The Audi TT clubsport quattro: Open-Top Driving Machine with over 300 hp
​

​

• Audi presents its showcar at the Wörthersee Tour
• Speedster-like body with dynamic accents
• Racing-like engine and suspension performance
​

An open cockpit, an engine producing more than 220 kW (300 hp) and a host of technologies borrowed from the world of motorsports – the Audi TT clubsport quattro is an uncompromising driving machine. Audi is presenting an updated version of the spectacular showcar and sensation of 2007 at the Wörthersee Tour, the big meet for Audi and VW enthusiasts in Reifnitz (Kärnten), Austria, from May 21 to 25.

Purism at a premium level – this was the goal that the designers and engineers set themselves for the Audi TT clubsport quattro. The low windshield is extremely flat. The A-pillars are nearly invisible, making the continuous window strip appear to be a single casting. Instead of the compartment for the soft top there are two humps behind the passenger compartment – the lines of the showcar painted in Suzuka Gray, pearl effect are intensely evocative of a speedster. Mounted in front of the humps are two massive rollover bars, which together with the strong A-pillars protect the driver and passenger if the car should roll over.

The front end is dominated by the powerful single-frame grill painted in high-gloss black. Beneath the headlamps, which feature a strip of LED daytime running lights, are large air inlets covered by horizontally split black grills.

A distinctive spoiler lip optimizes downforce. When viewed from the side, the sharp contours in the sill area are every bit as striking as the boldly accentuated wheel wells, which house impressive (polished) 9x19 inch wheels shod with 255/35 tires. The track was widened by 66 millimeters (2.60 inches) versus the production TT. The rear bumper is designed as a diffuser. The fascia between the two large tailpipes of the stainless steel exhaust system emphasizes the horizontal lines and makes the car look even wider from behind.

The purist style of the exterior carries over to the interior of the Audi TT clubsport quattro. The newly designed sill area emphasizes the width of the vehicle. The driver and passenger sit in racing bucket seats that offer excellent support even in extreme driving situations – on the race track, for example.

Typical Audi: aluminum in the interior
Typical for Audi is the generous use of aluminum in the interior of the showcar. The clubsport quattro sports a high-grip version of the flat-bottomed steering wheel from the production TT with aluminum shift paddles. The door pull handle and door opener are also made of aluminum, and their cut-out appearance emphasizes the lightweight design character of the concept car. The pedals also shine with aluminum.

The second distinctive feature of the interior of the TT clubsport quattro is the color orange. Leather in this color provides bright highlights to the arm rests, the sides of the center tunnel, the backs of the bucket seats and the instrument cowl. The orange and white graphics of the instrument cluster clearly distinguishes it from its counterpart in the production model.

The TT clubsport quattro is a true sports car, and technology borrowed directly from the world of motorsports emphasizes this character. Even more power has been coaxed out of the 2.0 TFSI engine – the turbocharged four-cylinder gasoline engine breaks the magic 300 hp barrier. The exhaust system was designed to be particularly easy-breathing, and a powerful racing sound exudes from the oval tailpipes.

Audi high-tech: S tronic and quattro
The two-liter engine delivers its full power to an S tronic transmission. Thanks to its dual clutch, gear changes occur extremely quickly without interrupting the flow of power and thus go virtually unnoticed. The driver can change gears manually using the shift lever or the paddles on the steering wheel, or can choose a fully automatic mode. The quattro permanent all-wheel drive system transfers the power to all four wheels.

The powerful brake system from the new Audi TTS provides the stopping power. Its ventilated discs measure 340 millimeters (13.39 inches) up front and 310 millimeters (12.20 inches) at the rear.

Audi A4 Earns Five Stars in the Euro NCAP Crash Test
​

• Mid-sized model one of the safest cars in its class
• Highest rating possible for the new A4 sedan​

After testing the new Audi A4 for passive crash safety, the Euro NCAP consortium awarded the vehicle five stars, the highest rating possible. The results achieved by the new Audi A4 for adult protection in frontal and side crashes as well as child and pedestrian protection make it one of the safest vehicles in its class.

The mid-sized model from the brand with the four rings was put to the test for passive vehicle safety by Euro NCAP. The consortium, consisting of international representatives from European ministries of transport, automotive clubs, insurance companies and consumer protection agencies, comprehensively examined the crash performance of new vehicles.

The Euro NCAP’s demanding test requirements substantially exceed the guidelines stipulated by European lawmakers. The data collected on the A4 for driver and passenger safety in frontal and side crashes earned the vehicle five stars, the best rating possible. The Audi A4 offers good protection for children as well: the test results for child safety are also high, with four stars earned.

Founded in 1997, the Euro NCAP consortium conducts crash tests with all of the important vehicles on the European market. It seeks to systematically improve safety in traffic, thus protecting the lives of all road users.

Audi regards providing partner protection for pedestrians and cyclists as an important task. A vehicle front end designed specifically to comply with this safety philosophy helps to mitigate consequences in the event of an accident. This development is rewarded with two of four possible stars in the Euro NCAP test.

Audi attaches even greater importance to the key issue of active safety in accident prevention. A high-performance, standard ESP brake system with brake assist was therefore one of the main requirements specifications in the development of the new Audi A4, and helps the A4 to achieve excellent results in independent comparative tests. In addition, customers can benefit from a wide range of optional driver assistance system previously available only in luxury-class automobiles. These include a radar-supported adaptive cruise control system with Audi braking guard that actively warns the driver in several stages of an impending collision, Audi lane assist and Audi side assist.

The New Audi A6: An Overachiever with New Strengths

• The world’s most successful business sedan just got better
• New engines – High efficiency and power
• Suspension refinements and new high-tech features

A winner always builds on his strengths: That’s why Audi has again upgraded its luxury class A6 model. Efficient engines have been added to the drive-train lineup, with innovative technologies cutting fuel consumption by about 15 percent across the whole model range. An improved suspension and new high-tech assistance system give the driver even greater control over the car. And the new-generation MMI control system is out-performing itself. The revamped A6 will be launched in the German market in late summer.

It’s the sportiest and most popular business sedan on the market. The Audi A6 is leading the Premium C pack – both in Europe and around the world. In 2007, Audi sold about 234,000 units, giving the A6 a 37 percent market share among its core competitors. Most of the A6’s sold were equipped with six- or eight-cylinder engines, permanent 4x4 quattro and a luxury assortment of optional equipment – all evidence of the high regard Audi technologies is enjoying worldwide.

Its design is emphasized by a range of bold new accents, perfectly articulating the A6’s strong personality. The single-frame grill, bumpers, air vents and fog lights have all gotten a facelift.

The optionally-available xenon plus, LED daytime running lights have been redesigned as horizontal strips with 6 LEDs each. Other options include Audi adaptive light, a dynamic cornering light system, and the high-beam assistant that automatically switches between the high and low beam.

An aluminum-colored molding traversing the sides emphasizes the A6’s dynamic contour. At 4.93 meters (16.17 ft) long, 1.86 meters (6.10 ft) wide, and 1.46 meters (4.79 ft) high, little has changed in the sedan’s generous proportions. The gentle lip on the trunk, integrated chrome strip on the bumper, broad diffuser and straight exhaust pipes are part and partial of the revamped rear end. The bipartite rear lights with LED technology have also gotten a new look: narrow and wide, they taper inward on the sedan. And there are 13 exterior colors to choose from, including five new ones.

The A6’s spacious interior with its clean and elegant contours and perfect craftsmanship is characteristic of this luxury brand. The rear seats are extremely comfortable and the L-shaped headrests improve the driver’s rear view visibility. As an option, the back seats can be fitted with a comfortable 2-seater bench. A package of elaborate features makes sure the noise level is cut by almost half, particularly within critical frequency ranges.

The instrument panel uses new higher-resolution graphics; and a new frame better accentuates the display (color in the optional MMI navigation system). Tastefully-appointed chrome trim, even on the spokes of the steering wheel, call attention to its overall elegance and inlays are available in either aluminum look or fine woods.

As is expected of an Audi, the interior designers have made sure all the colors and materials match. Standard seats can be optionally upholstered with a new material; the sport seats are available in Valcona leather. Soft armrests on the doors increase comfort, while the integrated headrest system reduces the danger of whiplash.

Audi is now offering an S-line sports package for the most dynamic of drivers. The package includes enhanced performance features like 18-inch wheels and sports suspension that lowers the ride height by 30 millimeters (1.18 in). Its sporty seats, decorative inlays and upholstery give the black-trimmed interior a feeling of even more exclusivity and the S-line exterior package provides more drama. Features from this Audi exclusive program are tailor-made to fit the A6’s luxury-seeking mavericks.

One of the major strengths of the A6 lies in its broad selection of engines: six gas and four diesels use direct fuel injection and cutting-edge FSI, TFSI and TDI technologies in a choice of four, six or eight cylinders. Whether stick shift, convenient tiptronic or high-efficiency multitronic, the energy literally flows to the front wheels, or all four wheels for that matter. Its engines are both powerful and efficient. New measures have been introduced to optimize engines and minimize fuel consumption without sacrificing one ounce of driving pleasure. Fuel consumption over the whole A6 family has been lowered by about 15 percent.

The smallest gas engine is the 2.0 TFSI, a 125 kW (170 hp) turbocharged four-cylinder unit. On the other end of the spectrum is the 4.2 FSI, a 257 kW (350 hp) V8 engine. Audi V6 models can be equipped with one of its two new 2.8 liter FSI engines; the 140 kW (190 hp) or the 162 kW (220 hp). Both engines feature the innovative Audi Valvelift System (AVS), which manages the inlet valve timing so that there is more torque and less fuel consumption. Regardless of which 2.8 FSI engine the A6 sedan is fitted, average fuel consumption is only 8.2 liters per 100 kilometers (28.68 US mpg) for the 190 hp, 6-speed manual shift or 8.4 liters per 100 kilometers (28.00 US mpg) for the 220 hp multitronic CVT.

With its 3-liter displacement and 213 kW (290 hp) power output, the V6 is a particularly exciting newcomer. Audi has designed the perfect package for each one of its engine. That’s why the 3.0 TFSI is fitted with a supercharger. From now on “T” doesn’t just stand for turbocharged – it stands for supercharged. Supercharger technology does not mean increased consumption – but the short intake paths do mean instantaneous response. And it’s got full power build-up even at low engine speeds: from 2500 1/min to 4850 1/min, the torque curve is broad and flat at 420 Nm (309.78 lb-ft).

The 3.0 TFSI comes with tiptronic and quattro drive train. The A6 sedan accelerates from 0 to 100 km/h (62.14 mph) in 5.9 seconds and keeps on going as it presses to its electronically-regulated maximum speed of 250 km/h (155.34 mph). This is the kind of performance that only an eight-cylinder engine would have been able to deliver a few years ago. At 9.5 liters per 100 kilometers (24.76 US mpg) on the EU cycle, the supercharged V6 is amazingly economical. The 3.0 TFSI’s combination of dynamic performance and low consumption is one more example of Audi’s successful efficiency strategy.

The A6 TDI engines give further evidence of just how closely Audi has been able to align sporty performance and efficiency. Fuel is delivered by the extremely sophisticated and quiet system of common rails with rapid-action piezo injectors and an injection pressure of 1800 bar (26,106.79 psi). The two V6 TDI engines (2.7 TDI with 140 kW (190 hp) and 3.0 TDI with 176 kW (240 hp) have peak torques of 380 Nm (280.27 lb-ft) and 450 Nm (331.90 lb-ft), respectively.

At the lower end of the diesel program is the four-cylinder 2.0 TDI engine, which is available in two versions: the 125 kW (170 hp), expected in fall 2008, and the 100 kW (136 hp). The basic version is an especially efficient e-model known as the 2.0 TDIe, which uses a six-speed manual shift or automatic multitronic transmission to deliver 320 Nm (236.02 lb-ft) of torque to the front wheels. With multitronic it sprints from 0 to 100 km/h (62.14 mph) in 9.9 seconds, and continues on to a top speed of 204 km/h (126.76 mph). Yet its average fuel consumption with a manual shift gearbox is only 5.3 liters per 100 km (44.38 US mpg), equivalent to CO2 emissions of app. 139 grams per kilometer (224 grams per mile).

The key to achieving such exemplary values is the strategic deployment of innovative technologies. The power steering pump operates on demand; the alternator regenerates electrical energy when coasting thereby reducing load off the engine. By lowering the ride height by 20 millimeters (0.79 in) and other aerodynamic fine-tuning, the drag coefficient has been reduced to cD = 0.28.

The transmission can be used longer in the upper two gears. Any manual-shift A6 with Driver Information System, even the 2.0 TDIe, can opt to have the shift indicator displayed in the instrument panel. The icon lets the driver know which gear is most economical under actual circumstances.

Audi quattro four-wheel drive is available on all engines with 140 kW (190 hp) or above and is standard equipment on high-end aggregates. The manual shift, 140 kW (190 hp) 2.8 FSI notwithstanding, this is the very latest generation quattro with the newly emphasized rear-end design. It gives the A6 tremendous driving characteristics, remarkable grip and superior safety. Under normal conditions, the torque split is 40 percent to the front wheels and 60 percent to the rear. The mechanically-operated Torsen differential immediately diverts most of the power to the axle, providing better traction whenever the need arises – in extreme cases, up to 65 percent to the front or 85 percent to the rear.

In fine-tuning the A6, two key objectives were identified – increasing its comfort while retaining its sporty character. With new large-diameter, front-axle shock absorbers operating within an optimized valve system, Audi engineers were able to achieve both goals. Every other aspect of the suspension set-up has been improved, including the automotive spring response.

The A6 can be equipped with factory-fitted adaptive air suspension so that the driver can vary his response and the characteristics of the adaptive shock absorbers into three styles. High-powered engines come equipped with larger 17-inch wheel brakes. Audi can also be fitted with a tire pressure monitoring system, which is entirely wear-free and maintenance-free. The customer can opt for run-flat tires, which limit the car to 50 kilometers (31 miles) should there be a drop in air pressure.
Audi has integrated several new high-tech assistance systems. The new Audi side assist kicks in to help drivers when changing lanes at speeds over 30 km/h (18.64 mph), ensuring a stress-free and superior drive. Using radar sensors, Audi Side Assist is able to detect other cars up to 50 meters (164.04 ft) away: a signal on the outside mirror lights up should changing lanes pose a threat. Audi lane assist helps keep drivers in their own lane, radar-assisted adaptive cruise control keeps a steady distance to the vehicle ahead, and Audi parking system advanced has a rearview camera.

Since its debut in 2002, the Audi Multi Media Interface system (MMI) has been setting the standard for perfectly controlling any number of functions. The A6 comes equipped with the latest MMI generation, including the top-of-the-line MMI Navigation plus. Its basic construction has not changed. The central control knob can still be found on the middle console between the front seats and the operation is still carried out using large buttons. The new joystick capping the control knob means the MMI Navigation plus can be operated even more intuitively.

MMI Navigation plus is an ultimate solution, pioneering in an entirely new system generation with high-tech portfolio and ground-breaking standards. Special features include a CD/DVD/Navigation combination drive with a 40 GB hard drive capacity which can be used to store MP3s and up to 5000 addresses.

With its 7-inch, high-resolution screen, the monitor on this ultimate navigation system is truly innovative. The image is rich in contrast and incredibly sharp even under difficult lighting conditions. It also has an optional TV tuner that receives digital programs (DVB-T) in perfect quality.

The new navigation system has another innovation. A new bird's eye picture mode shows landscapes in topographical relief – in full detail, complete with three-dimensional images of landmark buildings. The monitor has a new operating principle: when adjusting specific functions like air conditioning or seat heating, a pop-up window appears at the right rather than taking over the whole screen.

Most of the new features found in the A6 sedan and Avant are also present in two other models: the versatile A6 allroad quattro and the dynamic S6. The A6 allroad quattro can be powered either by the new 213 kW (290 hp) 3.0 TFSI engine or one of the two powerful V6 TDI diesels. The V10 on the S6 has 320 kW (435 hp). Changes made to the sports model are limited to interior and exterior optical details.

The upgraded Audi A6 will be available in German dealer showrooms as of mid-October 2008. Starting at 34,200 Euros for the A6 2.0 TFSI sedan, Audi’s initial list prices have remained virtually unchanged, despite all the extensive innovations.

Audi Develops Race Version of the R8

• Customer sport programme with the mid-engine sportscar
• First races planned for 2009 season
• Factory driver Frank Biela completes roll-out
​

Ingolstadt – For the first time, Audi Sport will offer a racing sports car specifically developed for customer use in the form of the powerful 500 hp plus GT3 version of the Audi R8 which will be available from autumn 2009. The logistics and factory space required for the AUDI AG customer programme will be created over the next few months in Ingolstadt, Neckarsulm and Györ.

"The R8 is the first production Audi bearing the name and genes of a successful racing sportscar and is therefore an excellent base from which to build up our first big customer sport programme,” explains Head of Audi Motorsport Dr Wolfgang Ullrich. "Ever since the R8 was unveiled we’ve been inundated with enquiries about a race version. With the Audi R8 we will offer customers a racing sportscar equipped with high-calibre technology and the typical Audi qualities, but which is nevertheless easy to handle.”

The Audi R8 conforms to the production-based GT3 regulations allowing the car to be fielded in numerous national and international race series.

Because the GT3 regulations prohibit the use of four-wheel drive the Audi R8 comes with the typical GT rear-wheel drive. The power is transmitted via a newly developed six-speed sequential sports gearbox. The suspension uses almost exclusively components from the production line. A comprehensive list of safety equipment guarantees the highest-level of passive safety. A modified front end and a large rear-wing generate the required downforce for the race track.

​

The Audi R8, which bears the project name "R16” within Audi Sport, was developed under the direction of Audi Sport. Mid August, the first prototype successfully completed a roll-out in the hands of Audi factory driver Frank Biela.

The first test races in various European racing series are scheduled for the 2009 season. Delivery to the customers is planned from the autumn of this coming year.

The customer cars are manufactured together by Audi Sport and the quattro GmbH, which is also responsible for production of the Audi R8 street version, and Audi Hungaria Motor Kft. (Györ).

Let's hope so.

 

[Speedster502]

Let's hope so.

I actually think I missed something. The R8 is a GT3 class, meaning it would be up against the Ferrari F430, Porsche 911 GT3's not the LMGT1/GT2 which would be against the Vette's and the DBR9's. That's a shame, they could have done with being in that class, more popularity and more of a following than the GT3 class. Although, if they get the right drivers they might be able to win the Nurburgring 24 Hour race.

Ah but remember, it is a while before Le Mans, you never know, by then they may have built a car for LMGT1/2(I hope), if not, im sure there will be one in years to come.
Anyhow, it will be against DBRS9's in the GT3 Series so don't think your safe just yet.

Good point, however as well as the DBRS9's coming into GT3 class the Aston V8 Vantage GT3 car should be making a debut sometime next year or this year depending on what Aston are up to, so a battle between those two should be quite closely matched.

Anyway, Aston will clutch victory. Just.

The New Audi S4/S4 Avant

• Three-liter V6 unit generates 245 kW (333 hp)
• Acceleration from 0 to 100 km/h in 5.1 seconds
• Average fuel consumption of just 9.7 liters
​

Ingolstadt – Audi is introducing its new sporty top models in the midsize class – the S4 and the S4 Avant. Their engine, a three-liter V6 with direct fuel injection and mechanical turbocharging, delivers a powerful 245 kW (333 hp). It accelerates the S4 to 100 km/h (62.14 mph) in just 5.1 seconds, but on average only uses 9.7 liters of fuel per 100 km (24.25 US mpg). The quattro permanent all-wheel drive system transfers its power to the road in style, which is then converted by the sport suspension into dynamic handling. Upon request, Audi can equip the new S4 and S4 Avant with innovative technologies that further increase their lead over the competition. The seven-speed S tronic changes gears with lightning speed, and the new sport differential distributes the torque as needed between the rear wheels. The new Audi S4 will be unveiled to the public for the first time at the Paris Auto Show from October 2 to 19.

The heart of the new S4 and S4 Avant is a completely redesigned engine. The 3.0 TFSI, the newest member of the Audi V-engine family, is an outstanding example of how the brand with the four rings blends performance and efficiency. The V6 generates its power from a displacement of 2,995 cc, is equipped with a supercharger, and delivers 245 kW (333 hp). The sedan sprints to100 km/h (62.14 mph) in just 5.1 seconds, and the Avant in 5.2 seconds: they both have an electronically governed top speed of 250 km/h (155.34 mph).

The "T" in the 3.0's TFSI nomenclature no longer merely stands for "turbo", but rather for the concept of supercharging in general – extensive testing on the big V6 has proven the superiority of mechanical charging. In conjunction with direct injection it is far superior to twin turbochargers, both in terms of packaging and of starting performance and responsiveness.

The compressor is so compact that it easily fits inside the 90-degree V of the cylinder banks, in place of the intake manifold. Two four-vane rotary pistons counter-rotate inside the turbocharger at up to 23,000 rpm. Two charge-air coolers are integrated into the housing and are connected to a separate coolant circuit. An impressive array of measures keeps the noise generated by the compressor to a minimum.

The engine-driven belt that powers the mechanical charger provides full thrust right from idling speed. The 3.0 TFSI delivers its maximum 440 Nm (324.53 lb-ft) at 2,500 rpm and maintains this constantly until 4,850 rpm. In fourth gear, the vehicle accelerates from 80 to 120 km/h (49.71 to 74.56 mph) in just 4.4 seconds. Thanks to the extremely short gas paths, the sonorous, supercharged V6 responds spontaneously to the throttle, even more so than a naturally aspirated engine of the same displacement.

Furthermore, the new 3.0 TFSI achieves exemplary fuel efficiency. On average, the sedan uses 9.7 liters of fuel per 100 km (24.25 US mpg), and the Avant 9.9 liters per 100 km (23.76 US mpg) – an improvement of 3.4 liters (26 percent) compared with its predecessor. The Audi technology of gasoline direct injection was what made this great efficiency possible in the first place. Unlike conventional concepts, it allows the compressor to be located behind the throttle valve. In view of the low density of the intake air at loads below supercharging level and when coasting, its rotors are free-running and the amount of power required to drive them is low.

Dynamism and efficiency: The new seven-speed S tronic
The V6 power in the new S4 and S4 Avant flows into a six-speed transmission, fitted as standard, which shifts quickly and precisely. As an option, Audi offers a state-of-the-art dual-clutch transmission – the seven-speed S tronic is extremely dynamic and highly efficient. The driver has the option of driving in fully automatic mode or selecting the gears with paddles on the steering wheel or directly with the shift lever – all of which provide impressively quick gearshifts. The gearshift feel is dynamic, comfortable and very precise – typically Audi.

The seven-speed S tronic consists of two separate transmissions and uses two multidisk clutches that control the various gears. The large K1 clutch guides the power via a solid shaft to the pinions for gears 1, 3, 5 and 7. A hollow shaft rotates around the solid shaft; it is connected to the compact K2 clutch, which is integrated within its larger counterpart and controls the pinions for gears 2, 4, 6 and reverse gear.

Both transmission structures are continuously active, but only one is powered at a time by the engine. For example, when the driver accelerates in third gear, the fourth gear is already engaged in the second transmission structure. The shifting process takes place as the clutch changes – K1 opens and K2 closes with lightning speed. This process takes only a few hundredths of a second and is completed without interrupting traction. It is so comfortable and smooth that the driver hardly notices it.

The seven-speed S tronic is designed for maximum efficiency. It operates with very high efficiency and its intelligent control system maximizes fuel economy in automatic mode. With its wide gear ratio spread of 8.0:1 the seven-speed S tronic easily exploits the tremendous power and superior torque of the 3.0 TFSI.

The quattro permanent all-wheel drive system transfers power to the road with supreme ease. Under regular driving conditions, it sends 40 percent of its torque to the front wheels and 60 percent to the rear wheels – a slightly rear-biased, sporty characteristic. Where necessary, it can vary distribution within fractions of a second.

The quattro drive system ensures safe self-steering characteristics, high stability and excellent traction in comparison with rear-wheel-drive competitors.

Customized torque distribution: The sport differential with Audi drive select
The new, active sport differential ideally complements the quattro drive system and lends it even greater fascination. When the steering wheel is turned or the car accelerated in a corner, power is redirected in a controlled manner to the outer rear wheel, literally pushing the vehicle through the corner. The system intervenes to counter any signs of understeer or oversteer. For the driver, this means reduced effort at the steering wheel and even higher lateral acceleration.

The active sport differential is a new type of rear-axle differential. A superposition gear was added to both the left and right sides of the classic differential; it rotates ten percent faster than the wheel's drive shaft.

Both components can be connected through a multidisk clutch, which runs in an oil bath, and is operated by an electro-hydraulic actuator. In most driving situations, the clutch can divert almost the complete input torque to one wheel in this way.

Controlled by an array of sensors and a high-speed computer, the active sport differential needs less than 100 milliseconds to redirect power. Drivers can adapt their manner of driving, along with characteristics for the load changes, to three performance maps. Unlike competitors' systems, the Audi sport differential is just as effective when the engine is driving the wheels as it is on the overrun or when the car is coasting freely.

The new Audi S4 and S4 Avant are well-trained athletes. Their five-link front axle and the self-tracking trapezoidal-link rear axle are of a highly sophisticated design; both axles are made almost entirely of aluminum and are therefore very lightweight. The low-mounted steering gear transmits the steering forces to the wheels without any lag time and gives the driver a precise and sensitive road feel.

The spontaneity of Audi's new midsize athletes is fascinating, and they possess the precise reactions of a thoroughbred sports car. In these transmissions, the differential is positioned in front of the clutch, which made it possible to move the engine 154 mm (6.06 in) forwards compared with the predecessor model. This unusual layout perfectly evens out the axle loads, and also affords the long wheelbase of 2,811 mm (9.22 ft) exceptional stability.

The chassis of both new S models received stiffer axle bearings, and the sporty tuning with stiff shock absorbers puts the chassis 20 mm (0.79 in) closer to the road. Huge high-performance and fade-resistant brakes sit behind the 18-inch and optional 19-inch cast aluminum wheels. The black-painted brake calipers – at the front with the S4 logo – grip the ventilated disks with newly developed brake pads.

Audi drive select: The driving dynamics system
The Audi drive select driving dynamics system is a further high-end technology featured on the new S4 and S4 Avant. It accesses the throttle response characteristics, the shift points for the seven-speed S tronic and supports the speed-dependent servotronic steering. With the press of a button, the driver can decide whether these systems should operate in "comfort," "auto" or "dynamic" mode. If the vehicle is equipped with the MMI operating system, a fourth mode is available which the driver can program according to his own personal tastes and preferences.

Audi drive select can only be ordered in combination with one or more of three additional technologies – the sport differential, adaptive control for the shock absorbers, or dynamic steering, which is an additional high-tech solution. Its zero-play superposition gear, which is driven by an electric motor, varies the ratio by almost 100 percent depending on the speed being driven. In terms of driver safety, the dynamic steering assists the ESP stabilization program by using steering intervention to keep the new S4 and S4 Avant on track when cornering at the handling limits. In many instances, the system renders ESP intervention superfluous.

For the adaptive damper control system, hydraulic gas-pressurized shock absorbers are used which operate by means of additional, electrically actuated valves. They control the flow of hydraulic liquid, thus regulating the shock-absorbing characteristics. A high-performance control unit analyzes the signals it receives from 14 sensors, and calculates the damping power for each individual wheel 1,000 times per second.

An athletic look: The design
Both the Audi S4 and the S4 Avant look athletic and muscular on the road. Some of the most striking modifications to the exterior design are the special aprons, the aluminum-look exterior mirrors, the 18-inch S-design light-alloy wheels, the side rocker panels, the restrained spoiler at the rear and the quadruple exhaust system. The xenon plus headlights with daytime running lights and the rear lights are further distinctive touches.

The interior also underscores the sporty expertise that is the hallmark of both new S models. The sports seats have electric lumbar supports and pull-out thigh supports, and the instrument panel features gray dials with white needles. They also bear the S4 emblems, as do the multifunction sport steering wheel and the key. The interior is in black, with brushed aluminum inlays. Carbon and birch wood inlays are also available, as are stainless steel mesh inlays.

Optional assistance systems provide the driver with even greater control on the road. The adaptive cruise control (ACC) regulates the distance to the vehicle in front, and braking guard issues warnings regarding possible rear-end collisions. The Audi side assist makes changing lanes safer; the Audi parking system advanced makes backing into a parking space easier.

With regard to multimedia, Audi offers an attractive technology package. The communications and entertainment technologies portfolio includes the competition-beating MMI operating system, various types of radio and sound systems all the way up to the high-end solution from Bang & Olufsen, two navigation systems, an iPod interface, and a highly convenient Bluetooth car phone.

Luxurious features such as the three-zone deluxe automatic air conditioning and the dynamic cornering light system known as adaptive light round out the optional equipment.

Audi will begin delivery of its new S models in March 2009.

[Turbo Lag]

A bit bland on the styling department, me thinks. I also like to see that the V8 is gone, IMO it should be left to the RS4. The Avant certainly looks great, and I'm sure will perform almost as well as the sedan.

The 2010 S4, competing with the BMW M3 and C63 AMG?

I like it. But the coupe is much sexier.

The 2010 S4, competing with the BMW M3 and C63 AMG?

Hopelessly outgunned by both cars. Strange they would say something like that, since it's clear if you look at the pricing that Audi USA is positioning the S5 ($51k) as an 'in-betweener', slotting nicely between the M3 ($58k) and 335i ($42k). Why they suddenly think the same car plus two extra doors and a hairdryer makes it a direct competitor to the M3 and C63 is beyond me.

Damn shame the Avant isn't coming here. I can see us trading wifey's allroad for one a few years down the road.

The Audi A1 Sportback Concept

Compact five-door model with hybrid drive
At the Paris Motor Show (October 2-10, 2008), Audi is unveiling the
A1 Sportback concept study: following on from the Audi A1 project quattro, the three-door show car presented in 2007, this is a concept for a five-door four-seater for the sub-compact class – once again exhibiting all the characteristics of a genuine Audi. The 3.99-meter long (13.09 ft) and 1.75-meter wide (5.74 ft) vehicle combines cutting-edge, dynamic styling with optimum economy of space and supreme quality. At the same time, a series of visionary technical solutions take efficiency, dynamism and motoring pleasure into new territory as only Audi knows how.

Audi is presenting another version of the innovative hybrid technology in the drive unit for the A1 Sportback concept. At work under the hood is a 1.4-litre TFSI engine developing 110 kW (150 hp), whose power is directed to the front wheels by means of the S tronic dual-clutch transmission. A 20 kW (27 hp) electric motor integrated in the drive train is able to deliver up to an additional 150 Nm of torque (110.63 lb-ft) when the vehicle is accelerating. During the boosting phase, i.e. when the TFSI engine and electric motor operate simultaneously to enable a sporty driving style, the two power packs deliver impressive propulsion. The tried-and-tested front-wheel drive – supplemented by the newly developed, ESP-controlled active front differential lock – ensures optimum transfer of power to the road.

The electric motor is furthermore capable of powering the vehicle alone for zero-emission driving in residential areas, for instance. The capacity of the lithium-ion batteries gives the vehicle a range of up to 100 km (62.14 miles) in pure electric mode; the motor can be recharged from any power socket. The automatic start/stop facility, energy regeneration and phases of purely electrical operation reduce the fuel consumption and emissions of the Audi A1 Sportback concept by almost 30 percent compared to when it is running on the combustion engine alone. Despite its sporty performance, with acceleration of 0 to 100 km/h (62.14 mph) in 7.9 seconds and a top speed of 200 km/h (124.27 mph), the Audi A1 Sportback concept requires only 3.9 liters of premium fuel per 100 km (60.31 US mpg); CO2 emissions are an efficient 92 g/km (148.06 g/mile).

The Design

Exterior
The difference is not down to the two extra doors alone: the styling of the five-door concept vehicle is a consistent development of the three-door study, the Audi A1 project quattro from the year 2007. Surfaces and lines are distinctly tauter and more masculine.

The basic proportions, with a high vehicle body and a flat window area bordered by a coupe-like roof line, produce a virtually classic look for a vehicle bearing the four rings. The rear end is rounded off by a two-part spoiler with a striking centre groove, integrated into the rear window.

The side-on view presents another typical coupe attribute in the form of doors with frameless windows and a glass-covered and thus homogeneously integrated B-pillar. The bold segmentation of the study's side paneling with its gently rising shoulder line accentuates the styling.

The shoulder line of the Audi A1 Sportback concept with its Daytona Grey paint finish is a new interpretation of yet another trademark feature of the current Audi design. Here, the prominent double lines continue around the entire vehicle as a curvaceous band that links the front end – from which it seems to emerge – with the vehicle's tail, which rises to create a slightly wedge-shaped effect.

The aerodynamically designed single-frame grille indicates the sporty ambitions of the study, which are further emphasized by the flared fenders – a tribute to the legendary Ur-quattro design and the current Audi RS 6.

The design of the three-dimensional main headlights in innovative LED technology is especially eye-catching. The completely new styling underlines yet again the amount of freedom that this technology has afforded to designers. All light functions – low-beam and high-beam headlights, daytime running lights and turn indicators – have been located in one flat housing, in concentrically arranged, parallel and squared-off strips.

The layout, with light segments of varying sizes – the low beam taking up most space – completely changes the character of the front section, the “face” of the A1 Sportback concept.

The rear lights, too, continue this theme and combine the function of tail and brake lights, turn indicators, reversing and rear fog lights into an unmistakable design. The interplay of acute and obtuse angles and the clear and colored glass areas create a particularly dynamic look. A large-dimensioned, transparent cover over the entire width of the vehicle additionally combines both light units and emphasizes the horizontal design of the rear.

Like the three-door version, the body of the four-door Audi A1 Sportback concept makes optimum use of the small road surface area available to a vehicle from the premium compact class. Measuring 3.99 m long (13.09 ft) and 1.75 m wide (5.74 ft) with a wheelbase of 2.46 m (8.07 ft), it succeeds in combining sporty looks with impressive economy of space thanks to its short overhangs. The transverse installation of the engine also has a significant role to play in this respect. The third dimension of this compact, sporty car – i.e. the height – comes in at 1.40 meters (4.59 ft).

Interior
The interior, with its four individual seats and a surprisingly generous amount of spaciousness for this class, has a tidy, no-frills appearance. The curved, wrap-around section combines the doors and the sporty cockpit into one single unit. The dashboard and center console are designed entirely around the driver.

Ergonomics and aesthetics unite to create an ambience of clear-cut architecture and high-class appeal. Details such as the turbine-look air vents and air conditioning controls seem to be straight out of a jet plane. This is where advanced form and precise function are combined in typical Audi fashion: air flow direction and volume can be regulated simply and intuitively by turning or pressing the control button in the centre of the vent.

The center console accommodates the integrated selector lever, only extended in drive select dynamic mode, the start/stop button for the engine, the switch for Audi drive select and the armrest with an integrated mobile phone pocket.

The sporty seats with integrated head restraints offer levels of comfort and ergonomics that far exceed the customary standards in the sub-compact class and live up to the expectations of a typical Audi. A transparent, mesh-like fabric covers the lightweight seat apertures, which further accentuates the airiness of the design.

The materials used for the interior trim appeal with their high-class looks and feel. The contrasting color scheme for the interior – white and red – emphasizes the feeling of spaciousness.

Audi mobile device – the second generation
Whereas the Audi A1 project quattro study featured its own mobile control unit for infotainment and vehicle systems, the A1 Sportback concept takes one step further into the future: the driver can use his commercially available mobile phone (equipped accordingly) as a car phone, address database, navigation system and audio/video player. At the same time it can be used as a control unit for numerous vehicle systems in the Audi A1 Sportback concept. Several phones that are suitable for these functions are already available from various manufacturers.

All that is required is some additional software, which Audi will provide on the internet for the driver to download and install. He can then enter his route plan or adjust the sound system to his individual preferences, all from the comfort of his own home, for example.

The mobile phone and vehicle communicate via a fast WLAN connection, even over considerable distances.

The system also offers the user a security function: within the range of the WLAN it can constantly monitor the current status of the vehicle, for instance whether all windows and doors are closed. What’s more, the additional software offers numerous comfort and convenience features such as continued destination guidance on the mobile device after the vehicle has been left in a car park. If the user sets a maximum parking time with the device, its navigation software leads him back to the Audi A1 Sportback concept – in good time of course, allowing for the current distance from the vehicle.

During the journey the mobile device demonstrates its strength as a portable media player. If the user listens to a song in a certain driving situation – on the motorway, for example – it is entered in an appropriate playlist. The software registers when and where the user prefers to listen to particular songs. The music is then available at the right moment.

The MMI control unit in the vehicle is a further development of the familiar design. In terms of feel it is easier to operate, particularly while driving. Grouped around the central rotary pushbutton are four fixed-function hardkeys for the Navigation, Telephone, Car and Media basic menus. Four additional, backlit softkeys have variable functions which change within the individual menus.

The projected softkey labels combine with the bold softkey colors that identify the corresponding menus to ensure swift, intuitive user orientation.

All system information appears in the central display in the instrument cluster. This is designed in its entirety as a digital, freely configurable display with no mechanical elements. Superimposed glass elements make the graphics stand out with a three-dimensional look, producing a level of depth which could never be attained using a standard display.

As well as the virtual, large circular dial of the analog speedometer, which is always visible on the right-hand side of the instrument cluster, numerous other displays can be called up on request, and can be selected via control buttons on the steering wheel. These include infotainment, classic navigation by pictogram or map, a rev counter, information on how to drive as efficiently as possible and a current status report on the hybrid drive.

The layout of the infotainment display features icons arranged in a semicircle. As the driver turns the central MMI rotary pushbutton, the icons mimic the movement until the desired function is selected by pushing the button. Content can therefore be communicated visually, enabling it to be grasped faster and more intuitively than pure text.

Audi drive select
The Audi A1 Sportback concept features Audi drive select, which is also available as an option in the current generation of the Audi A4 bestseller. This enables the driver to pre-select one of two specially adapted configurations for the drivetrain, shift characteristics and magnetic ride shock absorbers.

The default setting is the “efficiency” mode. In this mode, the engine and transmission respond gently to use of the accelerator and shift paddles. This setting is ideal for a relaxed driving style, as well as offering tremendous potential for effectively lowering fuel consumption, and therefore emissions too.

In the “efficiency” mode the Audi A1 Sportback concept can be used for distances of up to 100 kilometers (62.14 miles) in purely electric mode – and it is quite speedy, too: thanks to the powerful battery it is possible to reach a speed of considerably more than 100 km/h (62.14 mph). The combustion engine only cuts in again once battery capacity has dropped to below 20 percent of maximum.

In this mode, the electric motor is not deployed as a source of additional torque; instead it is run selectively as the sole power source to bring about a tangible reduction in consumption. For this purpose, the system makes use of a host of parameters which can be fed to it via the navigation system. In the “efficiency” mode, for example, with a fully charged battery and a distance of less than
50 kilometers (31.07 miles) the vehicle is operated in principle on purely electrical power.

Thanks to the navigation system’s ability to detect differences in altitude along the route, regeneration phases as well as the increase in energy requirements on inclines can be computed before the journey has even started. This makes vehicle operation even more efficient through optimum utilization of the electric motor.

The sport mode is designed to produce the dynamic yet comfortable driving sensation that is so typical of the brand and that Audi drivers have come to expect of their car. In this mode, the vehicle’s electronics also harness the torque available from the electric motor to achieve extra-sporty acceleration along with excellent lateral dynamics.

The drivetrain
Characteristic Audi sportiness plus a whole new dimension in efficiency – it is all down to the combination of a state-of-the-art turbocharged FSI engine with an electric motor and innovative control electronics.

Under the hood of the Audi A1 Sportback concept sits a four-cylinder TFSI with a capacity of 1.4 liters and a turbocharger. This engine is an advanced version of the unit that made its series production debut in the Audi A3. Whereas the 1.4 TFSI musters 92 kW (125 hp) in the A3, it delivers 110 kW (150 hp) at 5,500 rpm in the study. Its peak torque of 240 Nm (177.01 lb-ft) is on tap over a broad rev band from 1,600 – 4,000 rpm.

The Audi engineers have long since proven the performance potential of turbocharged FSI technology, both on race tracks around the world and out on the road. Indeed, a jury of experts awarded the accolade of “Engine of the Year” to the 2.0 TFSI for the fourth year in succession in 2008.

The new 1.4 TFSI builds on this very same concept in order to maximize efficiency and performance. Multi-hole injectors result in very homogeneous mixture formation and extremely efficient combustion. This is also an effective means of helping to cut pollutant emissions.

The integrated turbocharger promises optimized responsiveness and even more harmonious torque build-up. 80 percent of peak torque can be summoned up from as low down as 1,250 rpm, in other words barely above idling speed. And despite its power, the 1.4 TFSI sets new benchmark standards in its class for its acoustic output too.

Powertrain
Power transmission to the front wheels is the task of the sporty Audi S tronic dual-clutch gearbox. It allows the driver to change gear in fractions of a second without the use of a clutch pedal and with no interruption to the power flow. If required, the transmission performs the gear changes fully automatically, too. If the driver wishes to change gear manually, he can do so by using the shift paddles mounted on the steering wheel. Reverse gear and neutral are engaged via the gear knob on the centre console. The park position is automatically selected when the electric parking brake is engaged.

Between combustion engine and transmission sits the 20 kW (27 hp) electric unit, which cuts in automatically depending on the selected operating mode – or propels the vehicle alone. The battery unit – a package of compact lithium-ion batteries – is installed at the rear of the vehicle, which makes for a good weight balance.

When powered solely by the combustion engine or purely by the electric motor, and when both are used in the boost mode, the A1 Sportback concept operates as a front-wheel drive vehicle. The high torque of 390 Nm in total (287.64 lb-ft) –
240 Nm (177.01 lb-ft) from the 1.4 TFSI plus an extra 150 Nm (110.63 lb-ft) from the electric motor – is transformed into the required level of tractive power when accelerating.

Overrun, or the so-called regeneration phase, is one of the most important instruments of this vehicle concept for optimizing efficiency as it transforms the braking energy released during deceleration phases back into electrical energy, instead of it being wasted and released as heat.

The Audi A1 Sportback concept can in principle run self-sufficiently, using mixed operation of the combustion engine and electric motor. Thanks to the intelligent management of both units, energy regeneration as well as the automatic start/stop function, fuel consumption is almost 30 percent lower compared to a vehicle running on the gasoline engine alone. Although the components of the electric motor add around 40 kilograms to the overall weight, the study still only burns
3.9 liters of premium fuel per 100 km (60.31 US mpg) in mixed mode, while CO2 emissions average just 92 g/km (148.06 g/mile).

Pure electrical operation over shorter distances, however, is a particularly attractive alternative offered by this vehicle that benefits the environment and the wallet alike – all the more so considering that the performance achieved in this mode and the range of over 50 kilometers (31.07 miles) are perfectly satisfactory. “Refueling” the Audi A1 Sportback concept from power sockets alone, therefore, produces an unequivocal result: even allowing for the relatively high costs of domestic electricity in Germany, it is still possible to achieve a saving or more than 80 percent compared with the price of premium fuel. Thanks to “zero emissions” the benefit to the environment is even greater, particularly in congested urban areas.

The chassis
The fundamental ingredient for outstanding driving safety and handling dynamics is supplied by the sophisticated chassis design, comprising McPherson front suspension and four-link independent rear suspension. Large 18-inch wheels with size 225/35 R18 tires boost both driving pleasure and safety. Thanks to the newly developed active, ESP-controlled front differential lock, propulsive torque is distributed according to the driving situation, thereby achieving enhanced steering precision and superior directional stability as well as improved traction and dynamic handling when cornering.

The dynamic chassis is tuned for sporty, agile handling combined with excellent stability, and makes cornering a particular delight. What’s more, the chassis excels with a level of ride comfort befitting of higher vehicle classes.

The braking system with its large-diameter discs (measuring 312 mm across (12.28 in) at the front wheels) is more than a match for the drive power. Bred on the racetrack, the system promises outstanding, fade-free stopping power.

The electromechanical steering with speed-sensitive power assistance is also a boon for agile handling. The system boasts optimum steering feel combined with low sensitivity to road surface excitation and a considerable reduction in energy consumption.

The specific strengths of the four-link suspension stem from the way in which it splits the functions for absorbing longitudinal and lateral forces. This permits a high level of lateral rigidity on the one hand for optimum dynamism and driving safety, while offering a great degree of longitudinal flexibility on the other to improve ride comfort.

The shock absorbers deploy a highly innovative technology in the form of Audi magnetic ride, which has already made its mark in the Audi R8 high-performance sports car and in the TT. Here, the conventional shock absorber fluid is replaced by a magneto-rheological fluid whose qualities can be controlled by means of an electromagnetic field. This effect enables the damping characteristic to be influenced electronically at will by applying a voltage to the electromagnets.

Audi magnetic ride capitalizes on this quality to make the appropriate damping forces available in any driving situation, thereby optimizing both ride comfort and performance dynamics. A computer linked up to a system of sensors interprets the current driving situation with split-second speed. Here, the driver can choose between two driving programs, depending on whether he wants to drive with a sportier style – with the magneto-rheological fluid requiring a low yield stress – or with a greater emphasis on ride comfort.

The Audi A4 TDI concept e: The 58+ MPG Sedan

Efficiency is the way into the future – Audi is introducing the current state-of-the-art for its fuel-saving technologies at the Paris Auto Show. The A4 TDI concept e technology concept has the agile handling characteristics typical of the A4, but requires just 3.99 liters of fuel per 100 kilometers (58.95 US mpg). This exemplary result was possible through the concentrated use of innovative efficiency modules.

The engine
The heart of the sedan is a direct-injection diesel engine – a 2.0 TDI with output of 88 kW (120 hp), just as for the A4 production models. From 1,750 to 2,500 rpm, the four-cylinder engine produces a constant torque of 290 Nm (213.89 lb-ft), which generates impressive acceleration. The piezo injectors in the common-rail system inject the extremely finely atomized fuel at a pressure of up to 1,800 bar, and the special piston geometry provides ideal thermodynamics in the combustion chambers.

The 2.0 TDI also features a comprehensive package of additional efficient technologies. The oil cooler, the oil nozzles for cooling the piston crowns, the oil pump and the water pump have been designed so that they can be switched off – when inactive they do not require any power. New piston rings resulted in lower tangential forces, the spring pressure on the intake valves was reduced slightly, and the vacuum pump for the brake booster received a new actuator. These measures as a whole reduce emissions by 5 grams of CO2/km.

Other engine-related modifications include reduced internal friction, a new thermal management system during the warm-up phase and an electronically controlled fuel pump.

Just as in the production version, Audi is using a thermostatically controlled cooling circuit with an internal heat exchanger for the automatic air conditioning system. It responds in a highly efficient manner – the system uses 20 percent less fuel than its predecessor. The A4 TDI concept e uses a new controller: the engine disconnects the air conditioning system’s compressor from its drive whenever possible.

Like many Audi production models, the A4 TDI concept e uses a recuperation system that converts the energy of motion during deceleration into usable electrical energy. In the deceleration and braking phases the A4 TDI concept e operates with increased secondary voltage. At this point, it is able to convert the kinetic energy into electrical energy; it is buffered in an absorbent glass mat battery, which is a robust battery with a long life. Whenever the sedan accelerates again, the battery feeds the energy back in, thus reducing the load on the alternator.

Efficiency and agility are inextricably linked at Audi – as proved by the basic data for the A4 TDI concept e. The sedan sprints from 0 to 100 km/h (62.14 mph) in 10.7 seconds, and accelerates from 80 to 120 km/h (49.71 to 74.56 mph) in fifth gear in just 10.9 seconds. The A4 TDI concept e reaches a top speed of 206 km/h (128 mph).

Drivetrain and chassis
The 2.0 TDI transfers its power to a six-speed manual transmission which is notable for its considerably reduced internal friction. It was specially customized to the high-torque TDI engine and has somewhat taller ratios for gears three through six. Most of the housing consists of ultra-light magnesium, which reduces weight by nearly 5 kilograms. A foam-packed skin serves as insulation, ensuring that the transmission oil heats up faster after the vehicle has been started. The drive shafts from the differential to the front wheels have also been redesigned.


The transmission is coupled to a start-stop system that switches the engine off whenever the sedan comes to a standstill. The TDI is deactivated whenever the A4 TDI concept e comes to a standstill, the shift lever is in the neutral position, and the driver’s foot is off the clutch pedal. It starts up again as soon as the driver steps on the clutch – a specially developed starter handles this in around two tenths of a second, which is faster and smoother than a traditional component. While the driver puts the vehicle in gear, the TDI speeds up; as he takes his foot off the pedal, it drops down to idle speed.

The start-stop system improves the exemplary fuel efficiency of the Audi A4 TDI concept e still further, meaning that 5 grams less of CO2 are produced per 100 kilometers – as measured on the dynamometer. And in actual terms this reduction may turn out even higher, as many trips to work are less than ten kilometers long and are frequently interrupted by traffic lights.

Another important feature is that an electro-mechanical part replaced the electro-hydraulic power steering. This yielded a further reduction of 4 grams of CO2/km. It does not have to circulate any hydraulic fluid, nor absorb any energy while the vehicle is traveling in a straight line – its electric motor which provides power assistance only kicks in if the driver turns the wheel.

The electrical brakes are another technology module that shows how meticulous the Audi engineers were in their approach to efficiency. Thanks to active brake control, residual brake torque is almost non-existent. It only arises if the small air gap that is necessary for a stiff feel to the pedal and immediate brake response results in a slightly unevenly shaped disk rubbing on the lining. Using electrical rear-axle brakes will achieve the same effect on the front axle: here, an enlarged air gap is also possible since the power brake system only has to carry out the lining displacement for one axle.

Body and cockpit
The A4 TDI concept e glides sleekly through the wind. A trunk lid with a restrained separating edge adds a further dimension to the already excellent aerodynamics. The partially closed grid in the single-frame grille and sporty suspension tuning with optimized ride height also contribute to the excellent drag coefficient of 0.25 (production model: 0.27).

The underbody of the technology study painted in Daytona Grey is faired much more extensively than the production model; the rear lights feature LED technology, which uses much less power than regular bulbs. Newly designed, dip-polished cast aluminum wheels, of the size 7.5 J x 17 improve the flow of air around the wheels and wheel housings. The tires are designed for smooth running, but also provide sporty grip due to their 225/50 R17 wide format.

The intricate technology package from Audi’s modular efficiency system also takes the most important external factor of all into account as far as possible: the person behind the wheel. Despite the prominence of high-end technology, the driver remains primarily responsible for how fuel-efficient his vehicle is. This is a fact that Audi takes very seriously in relation to its efficiency strategy.

The driver will discover two major aids in the A4 TDI to help him drive economically. He can call up an efficiency program that shows up on the instrument panel display and which acts like an ecology trainer – pointing out open side windows or recommending rapid upshifting. And the navigation system will always offer an especially fuel-saving route as an alternative whenever the driver enters a destination.

The ‘e’ models from Audi
The Audi ‘e’ models are especially progressive, combining maximum efficiency with excellent dynamics. The Audi A3 1.9 TDI e and the A3 1.9 TDI e Sportback both achieve standardized fuel efficiency figures of 4.5 liters per 100 km
(52.27 US mpg) and a CO2 value of only 119 grams per km (191.51 g/mile). Both models have an output of 77 kW (105 hp) and a top speed of 194 km/h
(120.55 mph).

The new Audi A6 2.0 TDI e and its Avant equivalent are equipped with a 100 kW (136 hp) diesel. The sedan accelerates from 0 to 100 km/h (62.14 mph) in 10.3 seconds and has a top speed of 208 km/h (129.25 mph). Average fuel consumption for both models: only 5.3 l/100 km (44.38 US mpg). The A8 2.8 FSI e, with its 154 kW (210 hp) V6 on average consumes only 8.3 liters of fuel (28.34 US mpg), making it the most efficient gasoline engine in the luxury class.

Audi plans to expand its ‘e’ model line in the near future and start putting further technologies from its modular efficiency assembly into production. By the year 2012, the brand with the four rings will once again have significantly reduced CO2 emissions while continuing to hone its sporty, elegant profile.
