Tesla has added a new feature to Track Mode v3 with software update 2024.38.4 and higher. This update lets users configure how aggressively their powertrain is cooled.
One of the biggest challenges of racing or tracking Teslas has been sustained performance as drivetrain components start to heat up. Previously, performance was optimized for maximum power, which would result in very high performance initially, but performance would quickly degrade after multiple laps. With this update Tesla is now giving users more control of their vehicle’s performance and cooling.
Thermal Limiting
Tesla limits vehicle performance as components reach their thermal limit. These could be the brakes, motors, or batteries. While the battery performs best when hot, too hot isn’t good for its life either. In terms of the motors, as they get increasingly hot, they’ll be at risk of damaging themselves, so the vehicle will thermally limit itself.
Track Mode also provides aggressive cooling at an increased level before, during, and after a track session, which helps to ensure that the vehicle stays within its safe thermal limits as you push it as hard as possible.
Powertrain Endurance
Powertrain Endurance is available in the Track Mode V3 menu between the Stability Assist options and the Regenerative Braking slider. It has three options: Standard, Increased, and Maximum.
Standard - This essentially provides no change to the existing functionality, so you’ll get the fastest initial times, but you’ll be thermally limited more quickly.
Increased - This is the next step up, providing a balance between initial performance and sustained power. It’ll give you more steady performance over multiple laps, but you may still get thermally limited.
Maximum - This setting will reduce your vehicle’s performance but ensures that the vehicle’s available power will last for longer distances. This is the option many have wanted to see - a way to get maximum performance without getting thermally limited and having to slow down immensely.
Supported Vehicles
For now, this option appears to only be able available on Track Mode v3 vehicles with update 2024.38.4 and later. For now, that means only the 2024 Model 3 Performance - the Highland refresh - has that capability.
The Model Y Performance and the Model S Plaid are currently not receiving this feature. The Model X Plaid still lacks track mode, but that’s apparently still in the works, as is Track Mode of vehicles with the Acceleration Boost package.

We expect this feature to roll out to more vehicles when Track Mode V3 makes its way to other models in the coming months.
