To most of the people in this discussion, the discussion is about how to
achieve maximum acceleration during normal (or rather 'spirited')
driving, at whatever start and end speed the situation requires - and
the answer to that is to choose the right gear to get as near to maximum
power as you can, not maximum engine torque.


No. Vir Campestris started it again after say the same as many on here
seem to think. That an engine accelerates at its best at peak BHP. But was
wrong before and is wrong now.

I'm beginning to lose the will to live!

Yesterday, you you agreed with my two propositions. Please re-read the
second one and then explain why you are contradicting yourself by what
you are now saying.

Supposing that you had an infinitely variable transmission (with an
upper and lower limit, of course) and could program it to maintain the
engine speed constant as the car accelerated. If I understand you
correctly, you would argue that in order to maximise acceleration, you
would need to hold the engine at its max torque speed. Most other people
here would say that was nonsense, because you could get more power to
the wheels - and hence acceleration - by running the engine at its
maximum power speed instead. So where do you stand on this?
