Supercars generate 5x-10x more torque, which would likely break this sort of transmission. Most automatic transmissions have a similar planetary gear design but use clutches to control power delivery (from the single motor). These clutches will burn up under lots of torque. Furthermore, it would be hard to implement a way of shifting the CVT to a predictable ratio and holding it there while in a tight turn. (Holding the ratio might not be hard, but the driver will probably want a predictable ratio before going into the turn).

> Supercars generate 5x-10x more torque, which would likely break this sort of transmission Perhaps, perhaps not. Williams had a working CVT in the FW14C F1 car, which was pre-emptively banned at the behest of their competitors. It probably set back CVT research by a couple of decades, and marked the end of F1 as a tech testbed. Currently it's worth noting the Toyota are running the Lexus 450h in racing, and the Lexus LS600h runs a 327HP/520Nm V8 though a CVT mated to an electric motor running over 200 HP.
