Audi today unveiled the Q7 V12 TDI with an engine similar to the one featured in R10 Le Mans racing car. It produces 500 horsepower and 738 pound-feet of torque (1000 Nm). The crossover is capable of hitting 62 mph in 5.5 seconds, with a limited top speed of 155 mph. Maximum torque is available from just 1,750 rpm. The engine features the world’s first 2,000 bar Bosch Common Rail system. Up to 2,000 bar of pressure is kept within the twelve piezo injectors – a further technological breakthrough. Unlike other Audi V-engines, this model features a special cylinder angle of 60 degrees. The twin-turbo V12 TDI conforms to the Euro 5 emissions class which should come into force in 2010. Fuel consumption is 20 mpg (11.9 liters per 100 kilometres). Gallery after the jump…

i cant see pics either. is this going to come to the states? or is this just a project/concept or euro car like the W12 Touareg was? Why dont they offer the V10 TDI from the touareg?

Because the V-10 from the Touareg is weaker.

If it meets Euro 5, then it will meet EPA Tier 2 PM emissions requirements. However, Euro 5 allows for roughly twice the NOx emissions as EPA Tier 2 Bin 8. The audi will either have to use narrow angle direct injection or use a urea based exhaust aftertreatment.
The V-12 TDI engine makes less than the AMG v-12 Biturbo on account of the fact that it uses a 60 degree V (compared to the AMG’s 90 degree). This was done on purpose to limit the torque output as few gearboxes can handle more than 1,000NM (notice AMG “limited” theirs eh?).
BMW does the same thing with their inline 6 engines. An inline configuration produces the least amount of torque out of any engine design presently used. This is smart on BMW’s part, as they can increase power output (Hp, Ps, Kw, whatever you use) with out sending torque output (lb/ft, N/M whatever) to unusable levels.

Weird, as the Dodge Ram has a Diesel I-6 and it produces a monster 610 lbs-ft of torque but “only” 325 horsepower…and most semi trucks use an I-6 layout too, yet they need to haul up to 80,000 lbs or so. Did I perhaps miss something?

Other considerations in torque generation are, obviously, stroke length and compression ratio as well as the amount of turbo boost used.

This V12 seems to be a scaled up variant of the current 4.2L V8 TDI, which is rumored to replace the V10 TDI as it produces more power anyway.

yea not much to do with the race motor like everyone is going to think - 650 hp to match the R10 would have been nice a - 4.3ish 0-100 time for a big old truck woulda rocked

Looks like it had some bad plastic surgery, and the doc over enlarged her nostrils. Functional, though.

Not bad mileage for that much power. Though what’s the point of having something like this really?

This is the thinking man’s large SUV. I thought they were going to drop the engine into the A8? or better yet the R8 to better illustrate the brand’s racing success.

Are all of you aware this engine makes over 493 horsepower and 738 lb. ft. of torque? I hope you all know that. I also hope you all know it goes 0-62 mph in 5.5 seconds. But I’m mostly focusong on that 738 lb ft. Incredible.
