The M5 engine sacrifices low and mid-range torque for the high RPM torque (= HP) so you have to drive it to redline to make it feel fast. The M3 should feel a lot punchier in normal or even spirited driving due to its flat torque curve. Plus I'd guess they were trying to make the M3 get a bit better fuel economy than the M5's miserable 11/17 rating.
As SWAMP said (and I've agreed all the way along) they are saving that torque curve for the CSL. If the 3.6L flat six in a GT3 Porsche can make 415 HP (386 WHP, 115 HP/liter ), I am sure the M engineers can pull 450 HP or more out of the 4 liter for the CSL. |
It can hit 450 hp getting more torque in the last 2000-3000 rpm. This is where the engine spends its time during WOT acceleration.
Driveability and flat torque curves are great for getting lattes at Starbucks. I want an uncompromised torque curve in the last 3000 rpm of the rev range.
