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.

Radical Tesla aero patent may make new Roadster’s ~1-sec 0-60 mph launch feasible

The patent is for a multi-mode active aero system that uses fans and deployable skirts to generate controllable downforce.

A radical new patent from Tesla has provided a potential hint at a technology that the electric vehicle maker can utilize to meet the new Roadster’s ambitious 0-60 mph targets. If the technology outlined in the patent does come into fruition, it could help the Roadster stay planted on the ground even as it executes extremely rapid and demanding driving maneuvers.

The Roadster’s 0-60 mph time

When the new Roadster was announced way back in late 2017, Elon Musk stated that the upcoming vehicle would have a 0-60 mph time of 1.9 seconds. This was impressive, but the new Roadster has become so late that this metric is no longer industry-leading. Even Tesla’s own Model S Plaid, a large and heavy family sedan, can now hit a 0-60 mph time in 1.99 seconds, all for a price that starts just under $100,000.

Back in February 2024, Elon Musk stated that Tesla “radically increased the design goals for the new Tesla Roadster.” He stated that there will never be another car like the Roadster, if it could even be called a car. Musk also added that Tesla is now looking to achieve a 0-60 mph time in less than one second with the new Roadster, though this would be the “least interesting part” of the vehicle.

Inasmuch as a 0-60 mph time of 1 second or less sounds insane, these figures are achieved by vehicles like top fuel dragsters, which could accelerate well under 1 second. Of course, these vehicles are specialized machines and not road legal by any means, so the Roadster would still be in a class of its own if Tesla does manage to achieve a sub-1-second 0-60 mph time.

Tesla’s new aero patent 

A new patent from Tesla has now outlined a technology that could be a perfect fit for the upcoming all-electric supercar. Tesla’s patent is for a multi-mode active aero system that uses fans and deployable skirts to generate controllable downforce. This should pave the way for optimal vehicle grip and performance across varying conditions, from the track to the drag strip.

Tesla describes the patent’s technology as follows: 

“The system operates by creating bounded (e.g., sealed or partially-sealed) regions beneath the vehicle through the selective deployment of skirts that interact with the ground surface. Fans positioned in airflow pathways that extend to these bounded regions generate low pressure within these areas by extracting air, creating downforce that enhances vehicle grip and stability (e.g., by creating a vacuum, or partial vacuum in the bounded regions).”

If Tesla could indeed create a fully bounded region under the new Roadster using the technology outlined in the patent, the company could all ensure that the all-electric supercar always has perfect traction when it launches. It could also help the vehicle handle better in corners, which would be useful if the Roadster were to attempt setting records in tracks such as the Nurburgring.

Tesla’s new Robotaxi geofence shape is an FU by Elon Musk to the competition

Maybe it’s all pareidolia. But maybe it’s not. After all, Tesla embraced the first geofence expansion for what it appeared to be.

Tesla expanded its Robotaxi geofence in Austin once again early Sunday morning. The new shape seems to be somewhat of a proverbial, and potentially literal, middle finger to the competition.

If you thought the first expansion was a message to the competition and doubters of the company’s ride-hailing service, you probably will believe the second expansion is an even stronger gesture.

Tesla’s first expansion did not go unnoticed, as its shape was particularly recognizable. The company has always operated with a sense of humor, and it embraced what it did. Some, including me, took it as a message to competitors: We can expand in any direction, in any size, at any time. We’ll prove it.”

They picked a shape and went with it:

Tesla’s Robotaxi expansion wasn’t a joke, it was a warning to competitors

It is evident that Tesla is keeping its humor up to continue to show a few things. The first is that it really can expand in any direction it wants and that’s how it is choosing to show it.

The second, well, maybe it’s an edgier way to show doubters that it is really executing on Robotaxi:

Maybe it’s all pareidolia. But maybe it’s not. After all, Tesla embraced the first geofence expansion for what it appeared to be. This might be a similar occurrence, and it might be sending another message to the competition, critics, and doubters.

The expansion was a near-doubling of the geofence Tesla offered previously. After the initial geofence covered just about 20 square miles, Tesla was able to more than double it to 42 square miles with the first growth. This new geofence shape was just under double, and is about 80 square miles.

Tesla’s rapid expansion has impressed many, especially considering the service area has roughly doubled for the second time in well under two months. The Robotaxi service was first offered on June 22.

Tesla (NASDAQ: TSLA) executed what Wedbush’s Dan Ives called “a must” this morning as it finalized a new pay package for its CEO Elon Musk.

The move helped give Musk his first meaningful compensation at Tesla since 2017, when the company offered a pay package that was based on performance and proven growth. That package was approved by shareholders on two separate occasions, but was denied to Musk both times by the Delaware Chancery Court.

On Monday, Tesla announced on X that it had created a new package that would give 96 million shares of restricted stock to Musk to compensate him for the “immense value generated for Tesla and all our shareholders.”

The details of the pay package are designed to retain Musk, who has voiced some concerns about his control of Tesla, as “activist shareholders” have used lawsuits to disrupt the previously approved package.

Tesla rewards CEO Elon Musk with massive, restricted stock package

Ives says Musk’s retention is ‘a must’

Ives said in a note to investors on Monday that with the raging AI talent war that Tesla made a smart move by doing what it could to retain Musk.

He wrote:

“With the AI talent war now fully underway across Big Tech, we believe this was a strategic move to keep TSLA’s top asset, Musk, would stay focused at the company with his priority being to bolster the company’s growth strategy over the coming years. With this interim award increasing Musk’s voting rights upon this grant, which Musk honed in on and mentioned was increasingly important to incentivize him to stay focused on the matters at hand, this was a strategic move by the Board to solidify Musk as CEO of Tesla over the coming years with this framework for Musk’s pay package and greater voting control removing a major overhang on the story.”

He went on to say:

“While the groundwork is now in place for the next few years, it will be critical for the Tesla Board of Directors to get this long-term compensation strategy in place prior to the company’s November 6th shareholder meeting which would address the elephant in the room and remove a significant overhang on the stock.”

Wedbush maintained its Outperform rating and its $500 price target on the stock.
