There was some experiments with CVT in F1 in the early 90:ties. The gearbox aswell as the engine is of course controlled by microcomputers. Give full thottle and the computer takes the engine to max power while adjusting the gear ratio so a constant engine speed is achieved. That's however not the problem, the problem is to design a CVT which can take the torque and speeds involved without large friction losses and doing this while also being compact and light.
