1. 335 torque curve - all modern boosted engines focus heavily on the torque at low RPM. This is where the driver will "feel" the pull of the car during normal and spirited driving. I can tell you that an electric motor torque curve is actually the ideal torque curve shape for drive-ability. also in the 335, the turbo lag reinforces the fact you are receiving more torque at low rpm.
2. high rpm NA engines have a bias towards peak torque numbers at higher rpm and sacrifice low speed torque. This makes them feel slow when driving around town even with a little bit of liberal pedal application.
3. Perception is a resultant of many factors, however the actual acceleration is based on how much time is spent at xx Horsepower vs vehicle weight/aerodynamics/etc.. My guess is that driving an electric car with 250hp, you would say it feels faster than the Z with 332hp. This is why all manufacturers focus on torque at low engine rpm for future engines, peak power is a nice advertising number but the shape of the curve provides the feel of the car.
