Based on the newly posted Model 3 Performance review from Automobile (Quick Drive: Tesla Model 3 Performance AWD): "Go to the throttle smoothly on a fast corner exit and you’ll feel the lack of a true limited-slip differential as the inside rear tire lights up momentarily, before the new in-house Vehicle Dynamics Control (VDC—previously a supplier-sourced component) kicks in, grabs the brake, and forces the power to the outside wheel. Tesla says there’s an upgrade coming that will enhance this behavior by using active torque vectoring rather than the brakes to improve spirited (or track) driving performance. This new unofficial track mode is in development now, and not yet scheduled for release, but Tesla hopes to offer it to customers in the coming months. While it's exciting news for enthusiasts if it turns out to be true, I'm not sure how they would pull off active torque vectoring with the open-diff design of Tesla's drive units. Anyone have further insight into this?
