Default The physics of cars - a question sequence.

That's the problem - Mr Plowman *is*.

For the wheels to be turning or accelerating fastest -
in the absence of the car being powered by external
factors such as the wind propelling the body, they
need to be subject to the maximum available torque.


Indeed. And you obtain that by running the engine at max power and using
a suitable gear ratio. But Mr Plowman doesn't accept that. He says that
you have to run the *engine* at max *torque*. So he would end up using a
lower engine speed - producing less *power* - with higher gearing which
provides *less* torque multiplication - resulting in less torque at the
wheels. Mad!
