Tesla has announced that it is starting the rollout of Track Mode, a feature of the Model 3 Performance that allows the car to perform better on a racecourse, today. In light of the feature’s release, Tesla has published a blog post outlining the science behind Track Mode, as well as the feature’s specifics.

While Tesla’s other performance-oriented upgrades like Ludicrous Mode for the Model S and X help a vehicle with straight-line acceleration, Track Mode helps the company’s electric cars handle corners better. Tesla’s blog post notes that Track Mode was designed specifically to be used on closed autocross circuits and racetracks. The company also pointed out that its goal behind the development of Track Mode was simple — they wanted to use the power of the vehicle’s electric motor and instant torque to “make cornering on the track feel just as natural as forward acceleration.”

Track Mode enables vehicles to precisely control whether torque goes to the front or the rear wheels. This allows the Model 3 Performance to instantly increase or decrease the car’s rotation in a corner. With such a system in place, racing enthusiasts would find that highly technical driving sessions on a closed circuit would be a lot easier.

Unlike the usual Sport Modes of legacy carmakers, which usually involve the disabling of stability control, the Model 3 Performance’s Track Mode adds features to the vehicle. Tesla accomplished this by replacing the electric car’s stability control system with its own Vehicle Dynamics Controller — a software specifically developed for the company’s electric vehicles that acts as both a stability control system and a performance enhancement on the track. Tesla also provided a summary of the features that are employed by Track Mode when it is activated.

Motor Torque for Rotation

Our Vehicle Dynamics Controller continually monitors the state of the vehicle and all of the inputs from the driver to determine the driver’s intention and affect the rotation of the car in a matter of milliseconds. Track Mode relies heavily on the front and rear motors to control the car’s rotation, and we have the ability to command a 100% torque bias. When cornering, if rotation is insufficient to the driver’s request, the system controls a rear biased torque. Conversely, when rotation is excessive, we command a front biased torque.

Increased Regenerative Braking

Heavy regenerative braking may not be comfortable for day-to-day driving, but on a track, it has several key advantages. It gives the driver more authority with a single pedal, improves the endurance of the braking system, and sends more energy back into the battery, maximizing the battery’s ability to deliver large amounts of power. It also gives the Vehicle Dynamics Controller more authority to create or arrest rotation with the motors when your foot is lifted off of the accelerator pedal.

Track Focused Powertrain Cooling

The high output power required for track driving generates a lot of heat, so endurance on the track requires more aggressive cooling of the powertrain. We proactively drop the temperatures of the battery and the drive units in preparation for the track and continue to cool them down in between drive sessions. We can also allow operation of the powertrain beyond typical thermal limits and increase our refrigerant system capacity by overclocking the AC compressor into higher speed ranges.

Enhanced Cornering Power

We typically think of using brakes to slow down a car, but you can actually use them to make the car faster out of a corner. All Model 3s are equipped with open differentials, which send an equal amount of torque from the motors to both the left and right wheels. When cornering, the wheels on the inside of the corner have less load on them, which means they can provide less tractive force than the outside wheels. To prevent excess slip on this inside tire, we have to limit the torque for both wheels, leaving power on the table. In Track Mode, we simultaneously apply brake and motor torque to produce a net increase in tractive force while cornering. This is similar to how a limited slip differential works, except when using the brakes, the differential can be optimized for various driving conditions.

What is particularly exciting about the release of Track Mode is the fact that it is just the first version of the system. On its blog post, Tesla noted that Track Mode is set to improve further in the future through over-the-air updates.

When Elon Musk announced the Model 3 Performance on Twitter, he noted that the vehicle would be around 15% faster than a BMW M3 on the track. Considering the pedigree of the German-made performance sedan as well as the tendency of Tesla’s previous vehicles to throttle their performance on a track, Musk’s claims were met with a notable degree of skepticism from both avid car enthusiasts and critics alike. That said, initial reviews of the feature were notably positive.

Tesla conquered the drag strip with Ludicrous Mode. It remains to be seen if the company can do the same on the closed circuit with Track Mode. Considering the deliberate design of the feature, though, there is a pretty good chance that the Model 3 Performance would soon be just as formidable on the track as the Model S P100D is on the drag strip.

Tesla Robotaxi is set to launch in the coming days, but the first rides will be confined to those who receive invitations that the company sends out. However, CEO Elon Musk revealed the date that Tesla is aiming for when anyone in the general public will be able to call for a Robotaxi.

There has been quite a bit of information today about what appears to be an imminent launch of the Robotaxi platform. The first video of a Robotaxi was captured on a public road in Austin today, just one day after Tesla was added to the City of Austin’s list of licensed autonomous vehicle operators.

In the coming days, it is expected that Tesla will launch the Robotaxi platform in Austin to a select few. For now, Tesla is taking this ultra-conservative approach as it pertains to the rollout, citing safety precautions. It will be the first time Tesla has done this in public and offered it to people outside of the company.

It did launch a small, limited version of it to employees last month in Austin and the San Francisco Bay Area, but there was someone in the driver’s seat. Today’s video only had an occupant in the passenger seat.

People are eager to know: when will they be able to fetch a driverless Tesla Model Y Robotaxi in Austin for themselves? Musk finally answered the long-awaited question with a tentative date of June 22:

Musk cited that Tesla’s utmost priority is still safety and not necessarily the speed of rollout. The current plan seems to be to deploy it in a controlled and slow fashion until confidence is at an extremely high level. Musk seems to believe the rollout will go smoothly, as the date comes less than two weeks after the initial launch.

Anyone who has experienced Full Self-Driving for themselves knows what the cars are capable of. However, Tesla, at this point in time, still requires drivers to pay attention and remain ready to take over the wheel in case of an emergency. This will be a major step in the right direction for Tesla as it prepares to launch Robotaxi in Austin and slowly expand to surrounding areas.

Elon Musk says Tesla Robotaxi launch will force companies to license Full Self-Driving

“The automakers keep being told that this isn’t real or that just buying some hardware from Nvidia will solve it. As Tesla robotaxis become widespread and their other solutions don’t work, they will naturally turn to us.”

Tesla CEO Elon Musk says the automaker’s Robotaxi platform launch later this month will essentially force other companies to license Full Self-Driving to achieve their own goals of achieving autonomy.

Musk’s statement comes as a video captured today showed the first Tesla Robotaxi test mules on public streets in Austin, Texas, just one day after the City officially listed the company as an autonomous vehicle operator.

A prediction by investing YouTube and Tesla community member Dave Lee stated that “at least one automaker by end of year” will license Full Self-Driving from the Musk-led company, as it will give rivals the confidence to use the software to run their own self-driving operations.

Lee detailed his theory by stating that the company that chooses to commit to FSD licensing will not be able to integrate the hardware and sell those units immediately. Instead, it will take two years or so to solve the engineering and design applications.

Musk revealed his true thoughts on other automakers’ attempts at vehicle autonomy, and said many are being told that Robotaxi is not real or that they can solve their problems with hardware orders to Nvidia.

He went on to say that companies will be forced to turn to Tesla at some point or another, because Robotaxi will be widespread and their solutions to figuring out an effective deployment will prove to be failures:

“The automakers keep being told that this isn’t real or that just buying some hardware from Nvidia will solve it. As Tesla robotaxis become widespread and their other solutions don’t work, they will naturally turn to us.”

Musk has not been shy to respond to speculation regarding the video of the Robotaxi, which was shared on X earlier today. This is perhaps one of the more fiery things he revealed. He seems ultra-confident in what Tesla will prove and achieve in the near future with the launch of the Robotaxi platform.

Many believe it will be rolled out this month. Bloomberg reported recently that Tesla was internally aiming for June 12. The company has not directly responded to these rumors.

Tesla has discussed on several occasions that it is in talks with an automaker about licensing Full Self-Driving, but it has never revealed who. The company first revealed discussions with another automaker in early 2024 when Elon Musk said:

“We’re in conversations with one major automaker regarding licensing FSD. It really just becomes a case of having them use the same cameras and inference computer and licensing our software. Once it becomes obvious that if you don’t have this (FSD) in a car, nobody wants your car. It’s a smart car… The people don’t understand all cars will need to be smart cars, or you will not sell, or nobody would buy it. Once that becomes obvious, I think licensing becomes not optional.”

Tesla confirms it is in talks with major automaker for potential FSD licensing

Many, including us, suspected that Ford was the company that Tesla was speaking of due to Musk’s relationship with Jim Farley, which resulted in the legacy automaker being the first major car company to adopt Tesla’s North American Charging Standard (NACS), which gave them access to the Supercharging Network.

This catalyzed an onslaught of companies choosing to make the same move as Tesla had truly set itself apart in terms of charging infrastructure.

Companies may be forced to make a similar decision if it can make the same type of statement with the rollout of Robotaxi.

Tesla CEO Elon Musk reveals new details about Robotaxi rollout

The first Tesla Robotaxi unit was spotted in Austin earlier today, and CEO Elon Musk is revealing some cool new details.

Tesla CEO Elon Musk has revealed new details about the company’s relatively imminent rollout of the Robotaxi platform as the suspected launch date of June 12 continues to near.

Earlier today, the first video showing the first driverless Tesla Robotaxi in Austin was shared on X, just a day after the City officially listed the company as an autonomous vehicle operator on its website. Tesla is listed as a company in the “Testing” phase.

The initial details of the Robotaxi are being revealed by Musk, who is carefully releasing small tidbits that seem to show the capabilities of the entire Tesla fleet, and not necessarily just the vehicles that will be involved in the initial rollout in Austin.

His first tidbit is one that many Tesla owners and fans will already know: many Teslas are capable of this driveless performance, but Full Self-Driving is not yet refined to the point where the software is quite ready to handle it. Current versions are robust, but not prepared for driverless navigation. The hardware, however, will enable Teslas to be Robotaxis, even if they’re already purchased by owners:

This is one of the biggest advantages Tesla has over other vehicle makers. Simply put, the Over-the-Air software updates that will roll out to FSD users will eventually make their cars into Robotaxis as well.

However, Musk shed some details on the version of FSD that is being run in these new Robotaxis that were spotted. Musk said that the version these Robotaxis are running is a new version, but will soon “merge to main branch.”

There is also an even newer version that has four times the parameters as this newer version that the test-stage Robotaxis are using, but Musk admits that this needs significant refinement before it is released to the public.

As of now, Tesla is simply teasing the actual launch date of the Robotaxi program, but Bloomberg reported earlier this month that it will occur on June 12.
