Interesting Model 3 product info: the stock powertrain works quite well at the track:
Model 3 Track Day: Laguna Seca
Model 3 was able to complete 9 consecutive laps at full power. The Model S, in comparison, automatically goes into a reduced power mode under sustained throttle use that one would typically see in track use.
Model 3’s overall performance and handling appears to be superb, based on the driver’s feedback and the video posted. The only problem encountered was that the OEM brake pads were expended by lap 4, but this is to be expected. Brake pads for everyday street use are far less durable than brake pads for racing.
I don’t know why the Model 3 is able to do this when the Model S cannot. Perhaps the 3’s coolant system is better, or maybe the PM motor does not generate as much heat.
At any rate, Tesla has proved that their product can match or beat ICE capability in yet another application.
