Your brain is stuck in power and work mode which is not what is being discussed here, max acceleration is.

well, your brain is stuck in one-gear mode and peak acceleration is at the torque peak IN A GIVEN GEAR. if you DROP ONE GEAR and move to the power peak you will have MORE acceleration than at the torque peak in the higher gear. you seem to fail to realise this.

and if you wanna pull out the CVT argument, chew on this:
most speeds you won't have a gear available that puts you at either the torque OR the power peak. how do you answer that? this is how:
take any given speed. find the rpm you will be in ALL gears at that speed. the gear that has the highest POWER at the rpm the engine will be in when that gear is selected, is the gear that will have the highest acceleration. net result: maximize average POWER between gearshifts and you will cover x distance in the least amount of time possible. you're an engineer. surely you understand the math. work it out

besides the original intent of the thread is to see who understands the difference between torque and power

it is OBVIOUSLY apparent that both of us do. the rest here is arguing semantics.
