0-100 is Kmph and fuel is litres average per 100 Kms

3.0 V6 TDI 0-100 233 bhp 500nm 8.2 sec 10.5 per 100
4.2 V8 TDI 0-100 326 bhp 760nm 6.4 sec 11.1 per 100
6.0 V12 TDI 0-100 500 bhp 1000nm 5.5 sec 11.9 per 100

either web sites are quoting incorrect figures or the V8 has an advantage. It seems to give the best returns.
Any thoughts?

what do you mean about advantage? V8 is the middle both in terms of consumption and acceleration

Torque calcs in @ 700 nm - is 726, Accl calcs Approx 7.1 but is 6.4

I've seen powerful turbocharged engines with torque curves that are completely flat over a large part of the rpm scale, as boost/power is electronically reduced to avoid overstressing the drivetrain.

Also, what is top speed in 2nd/3rd gear for the various engines? Maybe the 4.2 needs one shift less getting to 100 than the others? I've seen a small sports car gain a full second on 0-100 with just a transmission change, as top speed in 2nd went from 95 to 105.

At the Q7 introduction party the Audi rep said the V6 will be first.Once moving he said its better than the gas V8

The 4.2 V8 TDI has numbers in the ballpark of the 4.2 gasoline engine. If it drives anything like the TDI in my father's golf, It'd be interesting to see if they would do it something like the s4. That way you would still have the smile on your face from putting your foot down, even after you visited the gas station.
