What is interesting is the 4.0 TFSI actually shows more torque than the 5.0 liter V10. Additionally, despite the torque advantage and the corrected horsepower figures being about 3 horses apart the wheels figures (the blue line) show a difference of 74.8 wheel horsepower which does not make much sense and does not appear to be accurate. The MAHA dyno automatically calculates losses and crank horsepower figures so let's just stick with the crank figures as they seem to be the most accurate.
Basically, the two cars are showing very similar power outputs. Audi was able to go smaller with the 4.0 liter V8 yet is not giving up much of anything. As APR's tuning results show, the 4.0 TSFI is a monster. Ditching the V10 has turned out to not be the step backward enthusiasts initially suspected it would be.
