Apologies if this has been covered, but what is the difference between the two that makes the performance model quicker? I know the performance model has bigger brakes, bigger wheels, lowered suspension and carbon fiber spoiler.... But what is it exactly that makes it quicker. It looks like it has the same two motors and same battery size. So, is it just a licensing thing where Tesla is somewhat limiting the power in the standard extended range AWD model? Or, does it have a different power inverter, etc.
