Tesla will remove performance limiting algorithm from cars in next software update
Tesla’s President of Global Sales and Service, Jon McNeill, has indicated that performance limiting software will be removed from Model S and Model X vehicles in the next over-the-air software update. McNeill’s announcement, made on the Tesla Motors Club (TMC) forum, follows reports that the company was limiting power on performance versions of its Model S and Model X vehicles through a software algorithm designed to protect the vehicle’s powertrain from excessive wear and tear. However, despite the intended safeguards, Tesla owners questioned whether it was right for the electric car maker to ‘downgrade’ performance on a vehicle that was intentionally purchased for its touted acceleration capabilities.
UPDATE: Tesla removes performance restrictions in new software update
Tesla Performance Limiting Discovered
Teslarati was first notified of the potential issue back in September of last year when local friend and Ludicrous Model S P90D owner, best known as Tech_Guy on TMC, sent us graphs showing the loss in power on his vehicle. At first, the issue was thought to be a result of the Firmware 8.0 update that introduced Tesla’s, then, latest Autopilot feature which put radar technology at the forefront.

Not sure of the cause for the power loss, Tech_Guy solicited feedback from his local Tesla Service Center only to be told that software on his Ludicrous Model S has limited power output because of too many uses of Tesla’s Launch Mode feature. The issue would eventually be surfaced across TMC, with other owners reporting the same loss in power. More alarming is the discovery that Tesla’s power limiting safeguard was taking place on non-Ludicrous cars and affecting owners with Tesla’s P85D vehicle. Even early P85 cars that pre-dated the company’s dual motor configuration were reported to be affected.
Tesla would later add a disclaimer to its online Design Studio confirming that limiting controls may be placed to protect the performance and longevity of the powertrain.
It’s not just ‘Launch Mode’ and ‘Max Power’
Service descriptions coming from owners who were concerned that their newly purchased inventory car, or in some instances their certified pre-owned Performance variant, might have been affected by the power limiting software, revealed that Tesla did in fact use an algorithm to ‘count’ presumably the number of times a vehicle was driven under wide open throttle.
The discovery of a possible performance ‘counter’ raises a question of ethics. If an owner purchased a used P85D that was performance limited as a result of too many hard acceleration runs in the past, will the owner know and is it right for Tesla to downgrade the vehicle to essentially an 85D status though they paid for a P85D? The same goes for inventory vehicles which one can argue is more likely to be driven under wide open acceleration, for demonstration purposes, than a brand new vehicle belonging to an owner.
Show me the Power
Hailed as a hero among the Tesla owners community, Tech_Guy blew the whistle and surfaced an issue that quite possibly may have never been discovered.
On Tuesday, January 17, 2017 at 4:41 PM Pacific Time, Jon McNeill, Tesla’s President of Global Sales and Service responded to concerns surfaced on TMC with the following:
Based on your input, we have decided to remove all software performance reductions tied to frequent max power usage. These changes will roll out with our next software update (in about three weeks).
We had put these reductions in place to proactively protect the powertrain from wear and tear. Instead, we will monitor the condition of the powertrain and let our customers know if service is needed so that we can take proactive steps, such as by replacing parts if necessary, to maintain the vehicle’s performance.
Heavy-footed Tesla drivers rejoice. You’re getting your power back.

Tesla wins another award critics will absolutely despise
Tesla earned an overall score of 49 percent, up 6 percentage points from the previous year, widening its lead over second-place Ford (45 percent, up 2 points) to a commanding 4-percentage-point gap. The company also excelled in the Fossil Free & Environment category with a 50 percent score, reflecting strong progress in reducing emissions and decarbonizing operations.
Tesla just won another award that critics will absolutely despise, as it has been recognized once again as the company with the most sustainable supply chain.
Tesla has once again proven its critics wrong, securing the number one spot on the 2026 Lead the Charge Auto Supply Chain Leaderboard for the second consecutive year, Lead the Charge rankings show.

This independent ranking, produced by a coalition of environmental, human rights, and investor groups including the Sierra Club, Transport & Environment, and others, evaluates 18 major automakers on their efforts to build equitable, sustainable, and fossil-free supply chains for electric vehicles.
Tesla earned an overall score of 49 percent, up 6 percentage points from the previous year, widening its lead over second-place Ford (45 percent, up 2 points) to a commanding 4-percentage-point gap. The company also excelled in the Fossil Free & Environment category with a 50 percent score, reflecting strong progress in reducing emissions and decarbonizing operations.
Perhaps the most impressive achievement came in the batteries subsection, where Tesla posted a massive +20-point jump to reach 51 percent, becoming the first automaker ever to surpass 50 percent in this critical area.
Tesla achieved this milestone through transparency, fully disclosing Scope 3 emissions breakdowns for battery cell production and key materials like lithium, nickel, cobalt, and graphite.
The company also requires suppliers to conduct due diligence aligned with OECD guidelines on responsible sourcing, which it has mentioned in past Impact Reports.
While Tesla leads comfortably in climate and environmental performance, it scores 48 percent in human rights and responsible sourcing, slightly behind Ford’s 49 percent.
The company made notable gains in workers’ rights remedies, but has room to improve on issues like Indigenous Peoples’ rights.
Overall, the leaderboard highlights that a core group of leaders, Tesla, Ford, Volvo, Mercedes, and Volkswagen, are advancing twice as fast as their peers, proving that cleaner, more ethical EV supply chains are not just possible but already underway.
For Tesla detractors who claim EVs aren’t truly green or that the company cuts corners, this recognition from sustainability-focused NGOs delivers a powerful rebuttal.
Tesla’s vertical integration, direct supplier contracts, low-carbon material agreements (like its North American aluminum deal with emissions under 2kg CO₂e per kg), and raw materials reporting continue to set the industry standard.
As the world races toward electrification, Tesla isn’t just building cars; it’s building a more responsible future.

Tesla Full Self-Driving likely to expand to yet another Asian country
“We are aiming for implementation in 2026. [We are] doing everything in our power [to achieve this],” Richi Hashimoto, president of Tesla’s Japanese subsidiary, said.
Tesla Full Self-Driving is likely to expand to yet another Asian country, as one country seems primed for the suite to head to it for the first time.
The launch of Full Self-Driving in yet another country this year would be a major breakthrough for Tesla as it continues to expand the driver-assistance program across the world. Bureaucratic red tape has held up a lot of its efforts, but things are looking up in some regions.
Tesla is poised to transform Japan’s roads with Full Self-Driving (FSD) technology by 2026.
Richi Hashimoto, president of Tesla’s Japanese subsidiary, announced the ambitious timeline, building on successful employee test drives that began in 2025 and earned positive media reviews. Test drives, initially limited to the Model 3 since August 2025, expanded to the Model Y on March 5.
Once regulators approve, Over-the-Air (OTA) software updates could activate FSD across roughly 40,000 Teslas already on Japanese roads. Japan’s orderly traffic and strict safety culture make it an ideal testing ground for autonomous driving.
Hashimoto said:
“We are aiming for implementation in 2026. [We are] doing everything in our power [to achieve this].”
The push aligns with Hashimoto’s leadership, which has been credited for Tesla’s sales turnaround.
In 2025, Tesla delivered a record 10,600 vehicles in Japan — a nearly 90% jump from the prior year and the first time exceeding 10,000 units annually.
BREAKING 🇯🇵 FSD IS LIKELY LAUNCHING IN JAPAN IN 2026 🚨

The strategy shifted from online-only sales to adding 29 physical showrooms in high-traffic malls, plus staff training and attractive financing offers launched in January 2026. Tesla also plans to expand its Supercharger network to over 1,000 points by 2027, boosting accessibility.
This Japanese momentum reflects Tesla’s broader international expansion. In Europe, Giga Berlin produced more than 200,000 vehicles in 2025 despite a temporary halt, supplying over 30 markets with plans for sequential production growth in 2026 and battery cell manufacturing by 2027.
While regional EV sales faced headwinds, the factory remains a cornerstone for Model Y deliveries across the continent.
In Asia, Giga Shanghai continues to be recognized as Tesla’s powerhouse. China, the company’s largest market, saw January 2026 deliveries from the plant rise 9 percent year-over-year to 69,129 units, with affordable new models expected later this year.
FSD advancements, already progressing in the U.S. and South Korea, are slated for Europe and further Asian rollout, complementing plans to expand Cybercab and Optimus to new markets as well.
With OTA-enabled autonomy on the horizon and retail strategies paying dividends, Tesla is strengthening its footprint from Tokyo showrooms to Berlin assembly lines and Shanghai exports. As Hashimoto continues to push Tesla forward in Japan, the company’s global vision for sustainable, self-driving mobility gains traction across Europe and Asia.

Tesla ships out update that brings massive change to two big features
“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”
Tesla has shipped out an update for its vehicles that was caused specifically by a California lawsuit that threatened the company’s ability to sell cars because of how it named its driver assistance suite.
Tesla shipped out Software Update 2026.2.9 starting last week; we received it already, and it only brings a few minor changes, mostly related to how things are referenced.
“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”
The following changes came to Tesla vehicles in the update:
- Navigate on Autopilot has now been renamed to Navigate on Autosteer
- FSD Computer has been renamed to AI Computer
Tesla faced a 30-day sales suspension in California after the state’s Department of Motor Vehicles stated the company had to come into compliance regarding the marketing of its automated driving features.
The agency confirmed on February 18 that it had taken a “corrective action” to resolve the issue. That corrective action was renaming certain parts of its ADAS.
Tesla discontinued its standalone Autopilot offering in January and ramped up the marketing of Full Self-Driving Supervised. Tesla had said on X that the issue with naming “was a ‘consumer protection’ order about the use of the term ‘Autopilot’ in a case where not one single customer came forward to say there’s a problem.”
This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.
Sales in California will continue uninterrupted.

It is now compliant with the wishes of the California DMV, and we’re all dealing with it now.
This was the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” names. Previous Transportation Secretary Pete Buttigieg was one of those federal-level employees who had an issue with the names “Autopilot” and “Full Self-Driving.”
Tesla sued the California DMV over the ruling last week.
