Tesla’s two Model S ‘Plaid’ variants are being benchmarked against each other
True to its word, Tesla has returned to the Nürburgring with two “Plaid” Model S units. Both vehicles have been spotted running hot laps since they arrived at the iconic German racetrack, and if recent observations are any indication, it would seem that Tesla has actually brought two variants of its track-capable Model S for its Nürburgring comeback. What’s more, it seems that Tesla is benchmarking the performance of the two Plaid Model S against each other.
Tesla’s Plaid Model S units in the Nürburgring could be differentiated by their color and rear badges. One is a blue unit with a Dual Motor badge, while the other is a red vehicle that’s marked P100D+. Recent reports and accounts from sources in the area suggest that these two vehicles do not have the same performance. While both are Plaid Model S prototypes, their track results suggest that they are somewhat different, perhaps along the same lines as Porsche’s Taycan Turbo and Turbo S variant.

The differences between the two vehicles were hinted at last month during Tesla’s first excursion into the Nürburgring. Observing the two vehicles, a photographer from motoring publication Motor Authority mentioned that the blue Plaid Model S was able to complete a lap around the iconic German track in 7:40, a couple of seconds faster than the record set by the Porsche Taycan Turbo.
The same photographer also recorded an impressive 7:23 lap with the red Model S Plaid unit, which is identical to a hand-timed lap reported by German media outlet Auto Motor und Sport. Quite interestingly, Tesla departed from its initial Nürburgring rounds after the red Model S Plaid unit seemingly broke down in the middle of a hot lap.

These two vehicles returned to the Nürburgring this week. This time around, the Plaid Model S units sported a refreshed widebody kit that included side vents, and in the case of the blue unit, a massive rear diffuser reminiscent of the one used by Tesla in the next-generation Roadster. Images taken of the red Plaid Model S’ return to the nearly 13-mile closed circuit revealed that the vehicle was not equipped with a rear diffuser, though it had the same side vents and large rear spoiler with Gurney flap found in its blue sibling.
Interestingly, images recently acquired by Teslarati reveal that Tesla has installed the same large rear diffuser in its red Model S at the Nürburgring. The vehicle was brought over to the track at the back of the truck, and once on the road, it was clear that the additional aeros have been installed on the vehicle. A closeup picture of the track-capable flagship sedan further revealed that the red Model S Plaid was fitted with a front lip spoiler as well.

With these images in mind, it appears that Tesla is currently testing how each Plaid Model S prototype performs on the Nürburgring with and without additional aeros. This suggests that Tesla is likely benchmarking the two Model S Plaid units against each other, potentially as a way to refine and tune each vehicle’s performance for closed circuit driving. These efforts ultimately bode well for Tesla’s upcoming Plaid versions for the Model S and Model X, as the electric car maker appears to be leaving no stone unturned in its efforts to develop a flagship vehicle that can attack one of the racing world’s most notorious tracks with no hesitation.
Elon Musk has mentioned a few details about Tesla’s upcoming Plaid Model S. For one, the vehicle will have three motors, similar to the next-generation Roadster, which is equipped with one electric motor at the front and two at the rear. Musk also stated in a recent tweet that the production Plaid Model S, which will reflect the final iteration of the car that will set Tesla’s official Nürburgring record, is set to enter its manufacturing stage sometime in Summer 2020. Pricing for the Tesla Model S Plaid variants have not been revealed by Tesla, though Elon Musk has mentioned that the vehicles will be priced higher than the current top-tier Raven Model S Performance with Ludicrous Mode.

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.
