How does RPM translate to power?

by

So a poorly worded question but like…

It seems to me like american performance v8 engines don’t rev as high as some others..
for example like a Ford GT might go around 65 rpm. but like an audi has a rev limiter at like 80 rpm.
much more rpm but the Ford COULD totally win in a drag race. (Not saying it would, im just using these cars for example)

Like i see this with other cars too, like a Corolla XRS can go to 80rpm but could still lose to a Subaru BRZ that can only do like 70rpm

How is it that a engine that can do less RPM go the same or faster than the engine that can reach higher rpm?

  • What your missing is the fact that the TORQUE is what moves the car. Torque is a measurable phenomena, whereas HP is a mere result of a mathematical calculation. Looking at RPM by itself is useless. Try reading this for a better ubderstanding of what makes a vehicle drive as it does…..
