Tesla Model 3 Performance endures 31 hard launches with no throttling
The Tesla Model 3 could be considered as the electric car maker’s endurance champion in its current lineup. Not quite as quick as a Model S or Model X Performance in Ludicrous Plus Mode but capable of being driven hard for extended periods in a racetrack, the Model 3 Performance is a vehicle that has charmed even the staunchest gearheads of motoring media. Top Gear host Chris Harris, for one, described the Model 3 Performance as an “AK-47 disguised as a butter knife” during his review of the vehicle, which he found to be too plain in design compared to comparable ICE cars like the BMW M3. It should be noted that after his review, Harris noted on Twitter that he will be buying a Model 3 Performance for himself soon.
The Model 3’s endurance, both on the track and the highway, has been tested and proven by professionals and enthusiasts alike. Tesla and electric vehicle veteran Bjorn Nyland tested the Model 3 in the Autobahn last June, going flat at full speed in an attempt to overheat the car. He failed. The same is true for other reviewers such as Harris, who pitted the Model 3 Performance against the BMW M3-beating Alfa Romeo Giulia Quadrifoglio in a time attack battle. True to Elon Musk’s statements on Twitter, the Model 3 Performance, thanks to its instant torque that allows the vehicle to launch from 0-60 mph in 3.2 seconds, soundly beat the Giulia Q4 in a closed circuit.
Last week, Porsche made headlines when the company allowed Fifth Gear and Fully Charged host Jonny Smith to take one of its Taycan Turbo pre-production vehicles for a launch mode repeatability test. Conducted on an empty airfield, the test involved the EV veteran launching the Taycan Turbo at max power 26 times with no power throttling. The exhibition was impressive, and it invoked just how much work Porsche has put into the Taycan and its development. The Taycan’s feat also brought comparisons to Tesla’s Model S P100D, which was quicker off the line with its 0-60 mph time of 2.4 seconds, but is prone to limiting its power after multiple max power launches.
After watching the Taycan’s demonstration, Tesla owner Patrick Lawson opted to see if his vehicle, a Tesla Model 3 Performance, could accomplish multiple max power launches without losing power as well. Accompanied by his son, Lawson headed to a (mostly) empty stretch of road to test the endurance of his Model 3. In a message to Teslarati, the Tesla owner noted that with Track Mode on, he figured that his vehicle should be able to perform comparably to the Taycan.
By the 10th 0-60 mph test, Lawson noted that he was already feeling the effects of the Model 3’s multiple hard launches. The father and son duo continued over the next 30 minutes, hitting 31 consecutive launches in the Model 3. At that point, Lawson noted that his son was probably good for about 10 more launches, but that was about all he could handle. Interestingly, the Model 3 Performance, just like the Porsche Taycan Turbo, did not throttle its power at all. The 31st launch registered a 0-60 mph time of 3.11 seconds, which is in the same territory as the Taycan Turbo.
Granted, Lawson’s test did not involve the same parameters as Fully Charged’s test of Porsche’s all-electric car. The Taycan Turbo, for one, performed 26 runs that topped up at speeds of 200 kph (124 mph), while Lawson’s Model 3 Performance test only involved 31 0-60/0-70 mph runs. Nevertheless, it should be noted that the Tesla owner’s tests were conducted on a public road in the United States, which usually have speed limits of around 60-70 mph.
The Tesla Model 3 could be considered, in more ways than one, as a Trojan Horse of sorts. While the vehicle is considered as the “cheaper” Tesla (and this is accurate, of course), and while the vehicle experienced a notable period of anti-selling by the company, the electric car has been showing signs that there is more to it than meets the eye. With track capability and a price point that is notably more affordable than other premium EVs in the market, the Model 3 will likely be the vehicle that ultimately brings electric cars into the mainstream.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.
While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.
Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.
Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.

This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.
The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…
— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.
— Elon Musk (@elonmusk) March 12, 2026
Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.
