I believe in one thing, power to weight and nothing else. If you believe in dyno results then the M3 should destroy the RS4 but in every UK test where they were compared the difference is minimum, but compared to PTW the results match.

Power delivery and gearing also have as much to do with performance as HP and weight. The numbers on the new Porsche PDK tranny for all their lines are a great examples. In every case the PDK equipped car is actually heavier, but has the same HP. In every case the PDK car is quicker.
