Power is energy per unit time so to continue a given rate of acceleration at twice the speed you would need to make 4 times the power. Since you only doubled power you would cut the acceleration in half even though your torque remained constant. I hope everyone else here can see this obvious flaw.

Acceleration follows the power curve exactly.


wrong the second car would accelerate at half the rate of the first one at twice the speed. Otherwise you are correct with twice the power it would accelerate faster at any given speed than the first car.
LMFAO!
This is something you can actually try yourself. Get in a a non-turbo car (preferably a V6 or V8 truck, for the powerband) and put it in 1st gear. Mash on the gas when your at the RPM where the engine makes its peak torque. Feel that kick in the pants? Now bring the RPMs up there the engine makes it peak power, and mash the gas. You will notice that the car jumps much harder at its peak torque, because TORQUE moves the car. I said preferably a truck because of its torque curve, generally they make a lot of low end torque, and not much high end torque, the results will be more noticable. Yoru car literally follows the torque curve when it accelerates. My car pulls no harder at 3000RPMs than it does at 5000RPMs, because its making the same amount of TORQUE at those RPMS, you dont feel hp.
