You're here Model owners 3 who have opted for the Performance variant now have a reason to go on the track. Or, if the story is a guide, they will ignore the track and try the new software feature of the Track Mode software in a parking lot or winding road.
The track mode – to be clear – is designed for and should only be used on closed autocross tracks and race tracks. Here's why.
The software feature relies on dual electric motors to further increase vehicle performance. But in a new way. Until now, Tesla used the power produced by its two motors and its torque (the rotational force of an engine or, in this case, an engine) to create a vehicle with very high acceleration quick. Now, it uses the same engine power and torque to turn the Model 3 into a dynamo cornering (and drifting).
As Tesla explains in a blog post (and in the video below), the company has replaced the stability control system with its own internal vehicle dynamics controller, "a software developed specifically for Tesla vehicles, which serves both as a stability control system and as an improvement in performance on the track. "
This vehicle dynamics controller allows more rotation if needed. If the rotation is insufficient, the system controls a biased torque towards the back. When the rotation is excessive, it controls a front polarization torque. Track mode also improves cornering by simultaneously applying braking torque and engine torque to increase the pulling force during cornering.
It simply means that the system is designed to send all the power to the rear wheels while the driver turns in turns, pushing the tail outward. If the rotation becomes excessive, the power is transmitted to the front wheels, pulling the vehicle up and out of the turn.
When activated, the track mode also increases regenerative braking. This gives a break (ahem) to the braking system and returns more energy to the battery. This also gives drivers more control with just one pedal (the accelerator). This means that the driver can simply lift one foot off the throttle to get the braking that he is looking for when approaching a turn.
Track mode also anticipates powertrain voltage, which lowers battery and drive unit temperature in preparation for the track and continues to cool them between workouts.
What's even more interesting is the way Tesla has tweaked the functionality. Motor Trend's Randy Probst ended up working with the Tesla engineers during a circuit session on the Willows Springs Street circuit for the track mode to work as it should. The result was a time of 1:21:49, beating the recently tested Alfa Romeo Giulia Quadrifoglio, and comparable to the 2016 Porsche Cayman GT4.
