the model 3 drive unit has enormous cooling capacity, what with a head exchanger and an oil pump that spins faster as the motor gets hotter
the model S' large rear motor, by comparison, just has a gear driven oil pump that's dictated by wheel speed and no proper heat exchanger, which is why the model s famously couldn't do more than a few laps on a track before going into limp mode.
has anyone tried to fix this though? possibly adding an external oil pump with heat exchanger inline with the rest of the system. It doesn't need MUCH extra cooling, just some extra cooling
