Brabus Reclaims World's Fastest Sedan with the Twin-Turbo V12 Rocket
362.4 km/h (225 mph): The Brabus Rocket, built in small-series production based on the Mercedes CLS series, is the world's fastest sedan. During test runs on the high-speed track in the southern Italian town of Nardo the 348,000-euro high-performance automobile improved upon the previous record of 350.2 km/h, held also by Brabus with the E V12 Biturbo.

The heart of the new record car is the twin-turbo V12 engine from the latest Mercedes 600 models. It was fitted into the tight confines of the four-door with almost surgical precision. BRABUS increases displacement to 6,233 ccm with a special crankshaft, larger cylinder bore and forged pistons. In addition the engine is extensively modified internally: Airflow in both intake and outlet manifolds of both cylinder heads is optimized and sport camshafts are installed.

The Brabus engine specialists further equip the engine with custom-developed larger turbochargers, a more efficient intercooling system and a stainless-steel high-performance exhaust system with four exhaust pipes and low back-pressure metal catalysts. Newly programmed engine electronics orchestrate the perfect interaction of all new components and contribute not only to maximum power yield but also to meeting the latest EURO IV emission limits.

After the engine conversion, also available for all current Mercedes-Benz 600 and 65 models with twin-turbo V12 engine, the Brabus S V12 S Biturbo engine is the most powerful TÜV-tested engine of German origin: The maximum power output of 730 hp / 537 kW is produced at 5,100 rpm. Peak torque is 1,320 Nm, but is limited electronically to 1,100 Nm, available from a low 2,100 rpm.

In addition to the top speed of 362.4 km/h, limited electronically for street-legal operation to 350 km/h, the Brabus Rocket also offers acceleration at the highest level: 0 – 100 km/h in 4.0 seconds, 0 – 200 km/h in 10.5 seconds, 0 – 300 km/h in 29.5 seconds.

Power is transferred to the rear wheels via a modified five-speed automatic transmission and the Brabus locking differential.

The Brabus Rocket engine and the entire drivetrain are operated with high-performance lubricants from technology partner ARAL.

Naturally the unique performance of the world's fastest sedan must be kept safely in check at all times. In order to do so Brabus in cooperation with Bilstein has developed a custom-
calibrated height-adjustable coil-over suspension with gas-pressure shocks for the Rocket. The shocks feature six settings each for bound and rebound.

Maximum size and state-of-the-art materials characterize the Brabus high-performance brake system of the Rocket. The front axle features vented ceramic brake discs in size 375 x 36 mm and 12-piston aluminum fixed calipers. Vented and perforated steel discs in size 355 x 28 mm and 6-piston aluminum fixed calipers on the rear axle complete this efficient and strong brake system.

The giant size of the brake components and the enormous vehicle performance necessitate the use of Brabus Monoblock VI or S light-alloy wheels with 19-inch diameter. Brabus technology partner Yokohama made the record run possible with the help of its Advan high-performance tires. The perfect tire/wheel combination for the Brabus Rocket features 8.5Jx19 wheels in front with 255/35 ZR 19 tires and 10Jx19 rims with 285/30 ZR 19 tires on the rear axle.

Specifically for the Rocket the Brabus designers have developed a front apron with large air inlets for optimal airflow to radiator and oil coolers. Like all other Brabus body components for the four-door the front spoiler received its final aerodynamic touches in the wind tunnel. It not only reduces lift on the front axle but also contributes to a further improved drag coefficient.

Its aerodynamic counterpart on the rear axle is the custom-developed Brabus rear spoiler lip. It emphasizes the bow-shaped design of the rear and together with the front apron improves directional stability by minimizing aerodynamic lift.

Integrated lights are the main feature of the Brabus rocker panels and rear apron. Pushing a button on the keyless-entry remote or pulling on a door handle activates five LED lights on
either side and in the rear. They illuminate the ground on both sides and behind the vehicle for added user friendliness in the dark.

The Brabus rear apron is the perfect stylish backdrop for the four tailpipes of the Brabus high-performance brake system. Its integrated diffuser is also part of the refined Brabus aerodynamic-enhancement concept for the Rocket.

The Brabus Rocket also meets the expectations of the most discriminating customers when it comes to the interior of one of the world's most exclusive automobiles. Soft and breathable
Brabus Mastik leather and Alcantara are part of the exclusive Brabus ambiance as an ergonomically shaped Brabus sport steering wheel and the speedometer with 400-km/h scale.

For high-speed fans there is now the Brabus polo shirt "Special High-Speed Testing Edition." The high-quality shirt is available in the Brabus online shop at www.brabus.com in sizes S through XXL and costs 75 euros.

Finally someone has done something even more pointless than AMG. And they did with the CLS, and incredibly pointless car. Take one E-class, lop off any extra useable passenger & cargo room that gives it more room than a CLK, then stuff in the most ridiculous engine you can that won't eat the tires for at least 2 miles.

Sounds like good fun, though.
 
Ditto... and by the way, Brabus... isn't the CLS officially a four-door coupe? :lol: That means it still doesn't get the prize. :lol:
 
Yeah...all of that effort that Mercedes-Benz put into marketing the CLS as a "four-door coupe," and Brabus just goes and calls it a sedan... :lol:

When I read what they had accomplished, only one thing popped into my head -- "would the M5's V10 be able to handle being turbocharged?" :trouble:

It's possible, but not likely. With a 12:1 compression ratio, it would have to be a pair of turbos from a VW 1.8T, and then only adding 7psi. Not that I wouldn't mind seeing it, though. It may be a bit nose-heavy (for a BMW) after the turbo work, but I haven't seen too many BMW's I can call "grunty". A twin-turbo V10 would be it.

Of course the compression ratio would be a problem. You would have to reverse some of the engine's natural-aspiration prowess (including lowering the compression ratio) before slapping the turbocharger(s) onto it.

The M5's V10 is so finely tuned that it would take some work.
 
That Brabus looks very nice, but the Rocket . . not the best name for a car, it's officaly my 2nd favourite Sedan/Coupe after the BMW M5 :)

But then after all that, would it really be worth it? It seems like such a wonderful, complex engine and you would have to throw out or change all the portions that make it what it is: high compression, VANOS, the entire intake & exhaust (probably no more individual butterflies).... After that, you'd be better off just buying a Viper V10, IMO.

"Some work" is an understatement.

You can have VANOS and the individual throttle butterflies. The 335i has the former and the Skyline GT-R has the latter.

The reason why you'd be better off with the M5's V10, as opposed to the Viper's V10, is that one is inherently more power-efficient and eager to rev to high RPMs. The other is just big.
 
That engine is not new. They build this enigine almost a year now and you can have it in several MB's...E-class, S-class, SL and CLS

I'd say almost a year is quite new...
Well... I dunno... matter of definiton. The record is new though, so I didn't want to critize this thread, just wanted to add some facts...actually I'd prefer that engine in the E-class or S-class... I really like Brabus, they look great, especially if you stand in front of them and they are pure understatement

What's the use of going 360 km/h with a car?

BTW: With four people, or even five, that car could NEVER go to 350.

Why?

Weight has precious little bearing on top speed. Five up it'd add just 11lb to the rolling resistance of the car, or just about 1% of the total resistance at 224mph.

You think a DOHC V10 is smaller than a OHV V10? Hasn't Chevy already proven that OHV is smaller & lighter than DOHC with the current LS series?

As for whatever the 335i and GT-R have, the M5/M6 has both. Variable valve timing has always been difficult to work around when adding turbos to non-turbo engines. Just ask the Honda tuning crowd. Puffing up a non-VTEC engine is much more straightforward than a B18C. Granted, there's lots of kits that can do that now, but it's been at least 10 years of work to get to this point.

And here we are presented with someone who would throw out the masterpiece that is the M5's induction system:

Sometimes I think I will never understand the human mind.... ;)
 
Ah, but doesn't the "production" title still with the Bentley Flying Spur? I think that could do a titch over 200 MPH, as the previous record holder was the Bentley Arnage T (168 MPH), correct?
