I have two other cars that have CVT (continuously variable transmissions). You accelerate best by holding the engine speed at the highest torque RPM, say 4000, and the car speeds up without ever changing engine RPM. The point being, torque is king, but torque at a higher RPM is a better king, because you can take advantage of gearing. If you have a CVT, then you don't need much of a torque curve at all.
