No, as I explained previously, it's horsepower that accelerates the car. The shape of the power curve is important as is gearing. The area under the power curve in the rev range determined by gear spacing and shift points is the total energy input to the vehicle. The higher it is, the faster the car will achieve speed and distance.

An engine that produces peak torque and power high in the rev range needs shorter overall gearing and closer spaced ratios to have the same average power input through the gears compared to a high torque low revving engine of the same peak power such as the examples I listed previously.
