回答: both torque and power are important 由 kfbai 于 2005-12-07 15:30:53

Let's say two cars accelerate at the same rate with the same torque. And torque is flat. Engine rpm keeps going up. At one point, engine with lower power hits its power limit. Its torque has to go down while the other engine keeps the same torque. This is when the car with higher power pulls away.

You may be able to plot an imaginable torque curve that an engine with the same torque and higher power rating accelerates less. But in reality, it is hardly the case. Engine with higher power does have advantage at high rpm. If you compare 0-10mph acceleration, power does not matter. If you compare 0-100mph acceleration, power is an important factor.

The tuning I mentioned is about drivetrain. It is an different topic anyway.
