On all the auto specifications card that I read, they mention 'bhp', which i guess is the power provided by the engine, when none of the transmission losses are counted. But, is the power of a engine constant?
Secondly, the also provide a specification 'Torque @ a certain rpm'. But, isn't Torque x Angular Velocity = Power? Then why are there 2 separate specifications given?
Also, what exactly happens when I press the accelerator of my car?
Also, lower gears have a low gear ratio. Hence, for every single rotation of the wheel, more torque is provided on lower gears than for higher gears [am i right?]. Why is a higher torque needed at lower speeds?
Thanks,
