Well, ignoring air resistance, the rate of acceleration will truly not drop in the new car, provided you manage to shift late enough such that the revs stay above 5500. Such is the unusual magic of having a wide band of constant peak power!

Of course, as you hold the gear and accelerate above 5500 revs, the acceleration will continuously tail off, for the same reason: constant power going through the drive train.
