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.
The 3 options in Track Mode V3

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.
There has been extensive reporting on what the long-anticipated affordable EV option would become, and we’ve seen numerous news stories mentioning that it was delayed or even arriving on time. The executive team revealed the near-term and long-term plans for Tesla’s upcoming vehicles, and there’s definitely good news to share here.
Updated Timeline
The most important piece of news is that despite all the talk of delays from supposed inside sources, Tesla has confirmed that the plan for its more affordable model remains on schedule for production to begin in the first half of 2025. Tesla’s executive team narrowed that timeline down further - and said that they expect production to kick off as soon as June and that the new model will be in the market shortly thereafter.
While the production timeline itself is on track, Tesla did note that the subsequent ramping process will likely be slower than initially hoped, citing global tariff and financial impacts as challenges to overcome to prepare its production lines.
Hybrid Production Approach
Tesla has once again confirmed that this will not be their next-generation vehicle, built using new production methods. Instead, they outlined a relatively more pragmatic approach for this new model.
Tesla will utilize aspects of both the next-generation platform as well as some parts of its current platforms (namely the Model 3 and Model Y). This means that Tesla will produce this new vehicle on the same manufacturing lines as the Model 3 and Model Y.
This strategy allows Tesla to bring the vehicle to the market more quickly, while also managing capital expenditures more efficiently by using existing infrastructure. However, Tesla’s executive team also noted that this approach, while faster, will result in fewer cost reductions than what might have been achieved with an entirely new platform and dedicated manufacturing process.
Vehicle Design
Using these existing production lines means that Tesla’s new vehicle will likely share some considerable similarities with either the existing Model 3 or Model Y. Rather than being a radically different and smaller vehicle, this new model will resemble the overall form factor and shape of Tesla’s current core offerings, while being optimized for a lower cost.
This doesn’t mean that Tesla is forgetting the overall goal here. Their ultimate goal is to reduce the initial cost of ownership and lower monthly payments for customers while maintaining a standard of excellence and safety.
Not Unboxed
Both at this Earnings Call and previous ones, Tesla has indicated that this new vehicle will not be using the innovative unboxed assembly method, at least for the time being. That relatively unique method will be developed and implemented specifically for the purpose-built Cybercab and for future vehicles on the next-generation platform.
We’re just a few days away from May, so it won’t be long before we see more about this upcoming vehicle. Stay tuned.
In a follow-up move to the current US administration’s goals to introduce a federal framework for autonomous vehicles, the US Department of Transportation (USDOT) is loosening autonomy restrictions following an announcement from Secretary Sean Duffy on X. This new initiative helps streamline complex regulatory processes and foster home-grown innovation.
From the Wright Brothers to the first astronauts on the moon, our nation has always been at the forefront of transportation technology.
That’s why today we're unveiling a new Automated Vehicle Framework from @USDOT’s Innovation Agenda ⬇️ ⬇️ pic.twitter.com/W3kbMUwQSn
As part of the broader upcoming USDOT Innovation Agenda, the newly unveiled AV Framework is designed to promote American innovation and strengthen domestic engineering while maintaining existing safety standards. The framework centers around three key principles:
Prioritize Safety
Unleash Innovation
Enable Commercial Deployment
To kickstart this AV framework, USDOT announced two initial steps focused on streamlining processes and expanding opportunities.
Crash Reporting Requirements
Under the first principle to Prioritize Safety, the National Highway Traffic and Safety Administration (NHTSA) will maintain its Standing General Order requiring crash reporting on Advanced and Automated Driver Assistance Systems (ADAS and ADS).
However, the reporting process will be streamlined following feedback from AV innovators, likely including Tesla. The goal here is to focus on collecting critical safety information while removing unnecessary or duplicative items from the reporting process, thereby reducing the burden without compromising safety.
Cutting Red Tape
Directly tied to the second principle of Unleash Innovation, the framework also seeks to slash red tape. The first step here is the expansion of the Automated Vehicle Exemption Program, or AVEP. This program allows manufacturers to petition for temporary exemptions from certain federal motor vehicle safety standards (FMVSS) for testing or deployment purposes.
Previously, the standard excluded domestically produced vehicles. Now, domestically produced AVs will not need to meet FMVSS, which will broaden the scope for manufacturers to test more innovative and unique designs and technologies.
Single National Standard for AVs
Finally, tied to the third principle of Enable Commerical Development, USDOT intends to move the United States closer to a single national standard for autonomous vehicles. This aims to prevent a confusing and inefficient patchwork of state-level or city-level laws and regulations, which can create hurdles for companies attempting to innovate, deploy, and scale their technology.
A unified standard across the United States also means that Canada and Mexico will likely be able to follow, as they share homologization standards across North America, including for vehicle crash safety and some autonomy regulations.
What This Means for Tesla
These framework changes will likely have a substantial impact on Tesla. The move towards a national standard is potentially the most impactful change, as Tesla identified regulatory hurdles as one of the most significant challenges it will face with the deployment of both Unsupervised FSD and its Robotaxi network.
The reduction of FMVSS requirements and streamlined reporting will likely play a role in the future as well. The FMVSS requirements are probably already being worked on, if not already met, by the Cybercab and other vehicles in Tesla’s lineup.
Meanwhile, the streamlined reporting will be helpful once Tesla officially launches its Robotaxi network in June.
