Most powerful diesel production car in the world

[Poverty]

Introducing the Q7 V12 TDI

Audi is proud to present a world first – the first twelve-cylinder diesel engine in a series passenger car. This six-litre V12 makes its debut in the Audi Q7. It produces a colossal 500 PS and 1,000 Nm of torque. With this engine Audi has opened a new chapter in diesel history.

The V12 TDI is reminiscent of the engine featured in the new R10 Le Mans racing car – it catapults the driving performance of the Audi Q7 into the echelons of top-class sports cars. The car sprints from 0 to 100 km/h in just 5.5 seconds, and has an electronically governed top speed of 250 km/h. Maximum torque is available from just 1,750 rpm. The high-tech diesel engine, with the world’s first 2,000 bar Bosch Common Rail system, provides the high-performance Audi SUV with superior power reserves in any situation. The impressive sound of the new Audi is provided by the ultra-modern piezo-injection system. The V12 TDI transmits this power through a new six-speed tiptronic gearbox to the quattro permanent four-wheel drive system.

Although the V12 TDI belongs to the Audi V-engine family, this model features a special cylinder angle of 60° – perfect for this engine type. Apart from the light and highly durable crankcase, a further highlight is the new chain drive assembly. This includes the two newly developed high-pressure pumps in the common rail injection system.

Up to 2,000 bar of pressure is kept within the twelve piezo injectors – a further technological breakthrough. Both performance and efficiency are optimised by this high injection pressure, and the running smoothness also remains excellent. Exhaust emissions are also low. The twin-turbo V12 TDI conforms to the Euro 5 emissions class which should come into force in 2010. Fuel consumption is only 11.9 litres per 100 kilometres. With the high-tech twelve-cylinder engine using TDI technology, the diesel pioneers at Audi have opened new horizons in motoring.


500PS, 1000Nm between 1,750 - 3000 rpm, 0-100km/h in 5.5s

- The fuel-injection system is working with a pressure of 2000 (!) bar and is completely new developed
- Average fuel consumption is estimated with 11.9 liters diesel (compared to 16 liters of a Porsche Cayenne V8)
- Extremely clean engine, fulfilling the pollution requirements of the Euro5 standard

Suuure, but what's the tow bar rating?

2nd most powerful production car in the world

Eh? 500PS? I can name you 2 BMW's that have more. And that's without mentioning the Veyron...

 

[Dave A]

With 737lbs/ft of torque I'd say it's going to be rather high.

daan it's probably referring to the torque figure, rather than the Bhp/ps. There's a lot of production cars with over 500ps out there, only one I can think of with over 737lbs/ft of torque though.

 

[amp88]

This isn't the 2nd most powerful production car in the world. Bugatti Veyron and 3 different models of Koenigsegg all produce more power and those are just off the top of my head.

Its the combined figure of torque and HP arcording to the article I quoted for the title. On the audi boards we have just worked out its tied second with the Merc 65AMG engine. A brabus beats it also but thats a tuner car, altough a manaufacturer in their own right?

Either way this is really impressive looking at the economy.

Actually the 65 AMG is more powerful overall.Either that article screwed up up or they are counting torque only as other than the veyron so far all other cars have 1000NM.

 

[Metar]

Meh, still an ugly SUV. I'd take the engine somewhere else, perhaps into the upcoming R8...

Engine looks cool, though. I'd like to see one in person...

Rumours suggest it will end up in the R8, and one with slightly more HP at that. The torque on this engine is limited by the gearbox though.

The SL65 has the same torque and over 100bhp more. How is that tied?

On the audi boards

Aah! Audi boards favour an Audi over a Mercedes.

Sorry I noticed that check my edits. I think the article must have been going by torque. But yes it is rather misleading what they were saying.

 

[JNasty4G63]

Oh, the things I could do with this ammount of torque and a curve like this in my Rubicon with the 4:1 LR and the front and rear diffs locked. UGH, its almost too awesome to be real. I WANT THAT!!!

PS - The article list it as the "Most Powerful Diesel Passenger Car", not just the flat-out most powerful car.

 

[red70mach1]

A tow vehicle with style. Since the 07 VW Toureg TDI is delayed for now.

 

[Jay]

I was waiting for a Audi road car to show with a modified Audi R10 Lemans engine.

 

[harrytuttle]

Not exactly pretty, but not really ugly either. It's an Audi uber-wagen, I suppose. A 500HP engine wouldn't have made much sense by itself, but neither does the V12-TDI in this car, although 20MPG is impressive for the power & weight figures.

Didn't VW make similar claims about "most powerful car" with the Touareg V10-TDI a few years ago? It was wrong back then, too.

In the R8, however, the V12-TDI makes perfect sense. Audi has a strong diesel presence in the European market, and this would be a great diesel sports car (a segment Peugeot could have had if they followed through on the RC Diamonds). Not that diesel is going to win in the long run anyway....

 

[JNasty4G63]

Well, they are calling it the most powerful DIESEL car in the world. So, if you can find a production passenger car that is more powerful with a diesel engine, you go ahead and let us and them know.

I dont like hoe the diesel engine sound, sounds like valves are going kaputt. but the tourqe at those low rpm is impressive for a car that is. trucks eat those figures for breakfast.

but at the same time a trucks rev limiter is around 2000/2500rpm

 

[Pink_the_Floyd]

What use does an SUV with a V12 has?

It's not a good offroader, we all know that. It cost serious lots of money.


And, it uses serious amounts of diesel which will costs again serious amounts of money.

IMO, these cars don't deserve the name SUV or offroader but FUGLY

No serious, a Landcruiser of Defender ownes this car with ease offroad...


BTW: V12, so much torque and still so slow? I buy a Supra which is probably at least half the price and it goes from 0-60 mph in 4.9 sec.

 

[Max_DC]

Hey comme on, it's a diesel...
Surely a great engine, I don't like diesel....

 

[CDailey]

A Supra weighs less than half of what that SUV does.

Firstly let me say that I dont like the Q7 or any other SUV.

1. Modern SUV's arent meant to be offroaders contrary to poluar belief due to marketing.
2. Its a diesel V12. Diesel = massive amounts of torque, coupled with a V12 to make it smoooooth.
3. Its alot more economical than equivelant performing SUV's.
4. They deserve the name SUV, but shouldnt be bunched in with offroaders.
5. It wasnt built to go offroad at all. Its a SUV, not offroader.
6. And I can buy a caterham with 170hp and beat a supra to 60.

And you may just see another.

 

[Scaff]

It still suffers from the same problem that hampers most diesel engines and thats the very narrow power band.

Almost all the torque is limited to 1,750rpm to 3,000rpm, which means to actually make the most of it in spirited driving you have to work within a range of 1,200rpm and change up very early.

Its what drives me nuts with diesel engines, my dad used to have a 330d and that was a total pain, to keep it on the boil you used to have to constantly swap cogs.

Still it is a nice looking car in the metal (but big for the UK).

Well, at 4500 revs, you still have 750Nm. That's less than the peak torque, but not exactly little, is it?
I have a 323 Bimmer, and I need to keep it between 3500 and 5000 revs to get the peak torque. It may sound better and be more fun in the process, but technically, it's not much of a difference, it's just higher up in the rev range.

That's not the point; its how it feels when you are driving, it may still be a lot of torque in isolation, but for the car itself you have just 'lost' 25% of the torque driving the car, and lost it quickly. The end result is that the car feels like you have just stopped accelerating.

The 330d has a wider peak torque range (but obviously not the same level) and when that drops off it feels like the brakes have just been put on.

I would also be surprised if the torque curve for a 323 was as steep in terms of gain and fall as any diesel engine, which again makes a huge difference to how it feels in terms of delivery.

Scaff

 

[the Interceptor]

Fortunately, I do have a torque curve of a 323 (the blue one), and as you can see, it drops from about 250Nm at 5000 rpm down to below 175Nm at 6500 rpm (= the redline).



I can tell you from first hand experience that it runs out of steam if you rev it to the redline, and that you're better off with shifting before you reach 6000. I know what it feels like in a Diesel, cause I regularly drive a Seat with the 140hp 2.0 TDI. But I wouldn't say that at high revs, it feels much worse than my 323. Yes, you do get the feeling that the engine kind of stopped working, and subjectively, it still feels different to my BMW. But figure-wise, there's not much in it. The problem with the Diesel is that, unlike a good petrol engine, it doesn't like high revs. So, it starts to feel kind of "greasy" if you rev it.

see below

.

Uh, yes it is, The q7 is the up scale Toareg, which is FANTASTIC off-road

And, it uses serious amounts of diesel which will costs again serious amounts of money.

Uh, but the SUV will most likely cost 70 to 80 thousand dollars. If you are that rich who gives?

IMO, these cars don't deserve the name SUV or offroader but FUGLY

All I have to say is Pontiac Aztek

BTW: V12, so much torque and still so slow?

ITS A DEISEL!





PS:everyone (including me... alot) makes stupid or silly posts but unless you want bad rep(like this post has recieved) please post informatively, with the correct information.

Happy Days,

Which is kind of my point, the torque curve for the 323 and the power curve are rising and peaking at a similar time and working closer to the red-line, hence the reason why they 'like' to rev. Most diesel power curves and torque curves are 'mismatched' hence the feeling that they do not like to rev power may still be rising, but torque is falling and falling sharply. Hence the braking feeling.

The torque curve for the 323 is much more progressive both in how it rises and how it falls.

However, remember I'm not having a 'pop' at the car or diesels in general, I'm simply saying I have an issue with this diesel characteristic when it comes to spirited driving.

.

Strange then that Audi themselves and every road-test for the Q7 I have read clearly state that the natural habitat of the Q7 is the road and that its off-road ability is clearly not a strong point.

Please, if any new members are reading this, don't post like this.

Close it out mr. dunce!

I would strongly advise that before using the dunce cap and insulting any member that you spell check your own work.

Its spelt DIESEL


In addition as someone who has been warned about there own posting quality I would strongly suggest you put your own house in order before advising others on how to post.

In closing as you are one infraction away from a ban yourself, insulting people is not a smart move.

Okay, now I got what you're on about. But you can work around that Diesel problem (and I guess that's what you did) with getting used to shift a bit earlier. Usually, you're still moving in the power band with the next gear, even if you shift early. So, spirited driving with a Diesel can be fun, if you forget about revs and just use its torque properly. 👍

That is correct although very few people realize that.
In my country one of the most sought out car is the Seat Ibiza 1.9TDI 130ps, young guys are absolutely in love with this car, since it's really fast, economical and it's easy to re-map the ECU to give it more power.
All of that is fine by me, the problem is the attitude that these guys have behind the wheel. They are absolutely convinced that they are driving the ultimate thing in hot hatches and cannot realize that a true ferocious car will always have a petrol engine. It always confused me this Diesel-is-the-fastest-car disease, I think that maybe it's because the kick you get when the turbo spools up. VAG were the first one to introduce this but nowadays every car maker has the same effect on their Diesel cars. Also people won't understand that if you put a turbo on a petrol engine the feel is exactly the same.
Of course since they think they are the Gods of the road, they absolutely cannot believe that they can't shake off a miserable 19 year old Celica with a 1.6 engine

EDIT: Most of the people that do Street Drag Racing with Diesels always rev-it up to the redline, wich usually means that they loose...
