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 has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.

Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.

This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.

This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.

Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.

Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.

The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.

Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.

For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.

Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country

Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.

Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.

The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.

Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.

In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.

The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.

The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.

These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.

However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
