There is electric throttle response throughout the rev range, and it makes peak power at its manic top end near 8000 RPM. It punches well low in the rev range, but boy does it pay to rev it out to the climax. The motor hits so hard at the top after a linear climb through the tach that it feels like it would almost do a wheelie. In M Mode, the individual throttle bodies make the pedal razor sharp, dancing to millimetric movements of your right foot. It’s breathtaking and intoxicating to embark on the journey from 4000 to 8250 RPM. And it sings with an induction note that makes NA BMW engines from the era so memorable. Every single time.
