Tesla’s Elon Musk addresses Taycan comparison, confirms +50 hp OTA update for Model S
Tesla CEO Elon Musk has provided a response to Top Gear‘s recent test of the Porsche Taycan Turbo S and the Tesla Model S Performance. In a couple of posts on Twitter, Musk noted that the Model S performance figures posted by the motoring publications are incorrect, and that an upcoming over-the-air update will be released for the flagship sedan to give it an additional edge against the top-tier Taycan.
Top Gear‘s Taycan vs Model S comparison was pretty balanced for the most part, with the publication noting that the Tesla is more comfortable for hauling passengers on long trips due to its superior range and large interior space. That being said, Top Gear also included a quarter-mile drag race between the two all-electric sedans, which reportedly ended with the Model S posting a 0-60 mph time of 2.68 seconds, a 0-100 mph of 6.46 seconds, and a quarter-mile time of 11.08 seconds at 124.0 mph.
These times, which were exactly identical to the results of a Model S P100D vs Mercedes AMG E63S drag race from 2017, as well as signs that Top Gear did not engage the Model S’ Launch Mode and full Ludicrous Plus Mode during its race with the Taycan Turbo S, were highlighted in a video by veteran drag racer and DragTimes host Brooks. According to the longtime drag racer, the figures posted by Top Gear were suspicious, to say the least, as it did not reflect the actual capabilities of a Model S performing at optimum capacity.
Musk responded to this comparison, stating that the DragTimes host is indeed correct in his observations. Never one to stand down, Musk also stated that the Model S Performance will be receiving a peak power increase through an upcoming over-the-air update. The update should add 50 hp to the flagship Model S, which should allow the flagship sedan to outrun the Porsche Taycan Turbo S in a 0-60 mph and quarter-mile sprint.
Elon Musk’s recent announcement provides a bit more detail to the upcoming OTA update that is being prepared for the Model S, X, and Model 3. The update was initially mentioned during the company’s third-quarter earnings call, with CEO Elon Musk and CTO Drew Baglino describing the upcoming improvements.
“We’re also expecting there’s going to be an over-the-air improvement that will improve the power of the Model S, X, and 3. That’s, by the way coming in a few weeks. Should be in the order of 5% power improvement due to improved firmware,” Musk said. Baglino added that the improvements are possible as Tesla continues to learn “how to optimize the motor control in our products.”
With Musk’s recent tweets, it appears that Tesla’s upcoming update will give the Model S Performance a 50 hp boost. That’s a 50 hp improvement that will be received by the all-electric sedan through a free over-the-air update. Once the update is fully rolled out, it would be very interesting to see how the Model S Performance stacks up against the Porsche Taycan Turbo S.

Tesla Cybercab tests are going on overdrive with production-ready units
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the vehicle being reported across social media this week.
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the autonomous two-seater being reported across social media this week. Based on videos of the vehicle that have been shared online, it appears that Cybercab tests are underway across multiple states.
Recent Cybercab sightings
Reports of Cybercab tests have ramped this week, with a vehicle that looked like a production-ready prototype being spotted at Apple’s Visitor Center in California. The vehicle in this sighting was interesting as it was equipped with a steering wheel. The vehicle also featured some changes to the design of its brake lights.
The Cybercab was also filmed testing at the Fremont factory’s test track, which also seemed to involve a vehicle that looked production-ready. This also seemed to be the case for a Cybercab that was spotted in Austin, Texas, which happened to be undergoing real-world tests. Overall, these sightings suggest that Cybercab testing is fully underway, and the vehicle is really moving towards production.
Production design all but finalized?
Recently, a near-production-ready Cybercab was showcased at Tesla’s Santana Row showroom in San Jose. The vehicle was equipped with frameless windows, dual windshield wipers, powered butterfly door struts, an extended front splitter, an updated lightbar, new wheel covers, and a license plate bracket. Interior updates include redesigned dash/door panels, refined seats with center cupholders, updated carpet, and what appeared to be improved legroom.
There seems to be a pretty good chance that the Cybercab’s design has been all but finalized, at least considering Elon Musk’s comments at the 2025 Annual Shareholder Meeting. During the event, Musk confirmed that the vehicle will enter production around April 2026, and its production targets will be quite ambitious.

Tesla gets a win in Sweden as union withdraws potentially “illegal” blockade
As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Swedish union Vision has withdrawn its sympathy blockade against Tesla’s planned service center and showroom in Kalmar. As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Vision’s decision to pull the blockade
Vision announced the blockade in early December, stating that it was targeting the administrative handling of Tesla’s facility permits in Kalmar municipality. The sympathy measure was expected to start Monday, but was formally withdrawn via documents sent to the Mediation Institute and Kalmar Municipality last week.
As noted in a Daggers Arbete report, plans for the strike were ultimately pulled after employer group SKR highlighted potential illegality under the Public Employment Act. Vision stressed its continued backing for the Swedish labor model, though Deputy negotiation manager Oskar Pettersson explained that the Vision union and IF Metall made the decision to cancel the planned strike together.
“We will not continue to challenge the regulations,” Petterson said. “The objection was of a technical nature. We made the assessment together with IF Metall that we were not in a position to challenge the legal assessment of whether we could take this particular action against Tesla. Therefore, we chose to revoke the notice itself.”
The SKR’s warning
Petterson also stated that SKR’s technical objection to the Vision union’s planned anti-Tesla strike framed the protest as an unauthorized act. “It was a legal assessment of the situation. Both for us and for IF Metall, it is important to be clear that we stand for the Swedish model. But we should not continue to challenge the regulations and risk getting judgments that lead nowhere in the application of the regulations,” he said.
Vision ultimately canceled its planned blockade against Tesla on December 9. With Vision’s withdrawal, few obstacles remain for Tesla’s long-planned Kalmar site. A foreign electrical firm completed work this fall, and Tesla’s Careers page currently lists a full-time service manager position based there, signaling an imminent opening.

Tesla Semi program Director teases major improvements
Tesla Semi Program Director Dan Priestly teased the major improvements to the all-electric Class 8 truck on Thursday night, following the company’s decision to overhaul the design earlier this year.
Priestley said he drove the Semi on Thursday, and the improvements appear to be welcomed by one of the minds behind the project. “Our customers are going to love it,” he concluded.
Just drove the redesigned Semi. Our customers are going to love it. https://t.co/KZ88sf1CDL

The small detail does not seem like much, but it is coming from someone who has been involved in the development of the truck from A to Z. Priestley has been involved in the Semi program since November 2015 and has slowly worked his way through the ranks, and currently stands as the Director of the program.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
Tesla made some major changes to the Semi design as it announced at the 2025 Annual Shareholder Meeting that it changed the look and design to welcome improvements in efficiency.
Initially, Tesla adopted the blade-like light bar for the Semi, similar to the one that is present on the Model Y Premium and the Cybertruck.
Additionally, there are some slight aesthetic changes to help with efficiency, including a redesigned bumper with improved aero channels, a smaller wraparound windshield, and a smoother roofline for better aero performance.
All of these changes came as the company’s Semi Factory, which is located on Gigafactory Nevada’s property, was finishing up construction in preparation for initial production phases, as Tesla is planning to ramp up manufacturing next year. CEO Elon Musk has said the Semi has attracted “ridiculous demand.”
The Semi has already gathered many large companies that have signed up to buy units, including Frito-Lay and PepsiCo., which have been helping Tesla test the vehicle in a pilot program to test range, efficiency, and other important metrics that will be a major selling point.
Tesla will be the Semi’s first user, though, and the truck will help solve some of the company’s logistics needs in the coming years.
