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.

Brazil Supreme Court orders Elon Musk and X investigation closed
The decision was issued by Supreme Court Justice Alexandre de Moraes following a recommendation from Brazil’s Prosecutor-General Paulo Gonet.
Brazil’s Supreme Federal Court has ordered the closure of an investigation involving Elon Musk and social media platform X. The inquiry had been pending for about two years and examined whether the platform was used to coordinate attacks against members of the judiciary.
The decision was issued by Supreme Court Justice Alexandre de Moraes following a recommendation from Brazil’s Prosecutor-General Paulo Gonet.
According to a report from Agencia Brasil, the investigation conducted by the Federal Police did not find evidence that X deliberately attempted to attack the judiciary or circumvent court orders.
Prosecutor-General Paulo Gonet concluded that the irregularities identified during the probe did not indicate fraudulent intent.
Justice Moraes accepted the prosecutor’s recommendation and ruled that the investigation should be closed. Under the ruling, the case will remain closed unless new evidence emerges.
The inquiry stemmed from concerns that content on X may have enabled online attacks against Supreme Court justices or violated rulings requiring the suspension of certain accounts under investigation.
Justice Moraes had previously taken several enforcement actions related to the platform during the broader dispute involving social media regulation in Brazil.
These included ordering a nationwide block of the platform, freezing Starlink accounts, and imposing fines on X totaling about $5.2 million. Authorities also froze financial assets linked to X and SpaceX through Starlink to collect unpaid penalties and seized roughly $3.3 million from the companies’ accounts.
Moraes also imposed daily fines of up to R$5 million, about $920,000, for alleged evasion of the X ban and established penalties of R$50,000 per day for VPN users who attempted to bypass the restriction.
Brazil remains an important market for X, with roughly 17 million users, making it one of the platform’s larger user bases globally.
The country is also a major market for Starlink, SpaceX’s satellite internet service, which has surpassed one million subscribers in Brazil.

FCC chair criticizes Amazon over opposition to SpaceX satellite plan
Carr made the remarks in a post on social media platform X.
U.S. Federal Communications Commission (FCC) Chairman Brendan Carr criticized Amazon after the company opposed SpaceX’s proposal to launch a large satellite constellation that could function as an orbital data center network.
Carr made the remarks in a post on social media platform X.
Amazon recently urged the FCC to reject SpaceX’s application to deploy a constellation of up to 1 million low Earth orbit satellites that could serve as artificial intelligence data centers in space.
The company described the proposal as a “lofty ambition rather than a real plan,” arguing that SpaceX had not provided sufficient details about how the system would operate.
Carr responded by pointing to Amazon’s own satellite deployment progress.
“Amazon should focus on the fact that it will fall roughly 1,000 satellites short of meeting its upcoming deployment milestone, rather than spending their time and resources filing petitions against companies that are putting thousands of satellites in orbit,” Carr wrote on X.
Amazon has declined to comment on the statement.
Amazon has been working to deploy its Project Kuiper satellite network, which is intended to compete with SpaceX’s Starlink service. The company has invested more than $10 billion in the program and has launched more than 200 satellites since April of last year.
Amazon has also asked the FCC for a 24-month extension, until July 2028, to meet a requirement to deploy roughly 1,600 satellites by July 2026, as noted in a CNBC report.
SpaceX’s Starlink network currently has nearly 10,000 satellites in orbit and serves roughly 10 million customers. The FCC has also authorized SpaceX to deploy 7,500 additional satellites as the company continues expanding its global satellite internet network.

Tesla Energy gains UK license to sell electricity to homes and businesses
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
Tesla Energy has received a license to supply electricity in the United Kingdom, opening the door for the company to serve homes and businesses in the country.
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
According to Ofgem, the license took effect at 6 p.m. local time on Wednesday and applies to Great Britain.
The approval allows Tesla’s energy business to sell electricity directly to customers in the region, as noted in a Bloomberg News report.
Tesla has already expanded similar services in the United States. In Texas, the company offers electricity plans that allow Tesla owners to charge their vehicles at a lower cost while also feeding excess electricity back into the grid.
Tesla already has a sizable presence in the UK market. According to price comparison website U-switch, there are more than 250,000 Tesla electric vehicles in the country and thousands of Tesla home energy storage systems.
Ofgem also noted that Tesla Motors Ltd., a separate entity incorporated in England and Wales, received an electricity generation license in June 2020.
The new UK license arrives as Tesla continues expanding its global energy business.
Last year, Tesla Energy retained the top position in the global battery energy storage system (BESS) integrator market for the second consecutive year. According to Wood Mackenzie’s latest rankings, Tesla held about 15% of global market share in 2024.
The company also maintained a dominant position in North America, where it captured roughly 39% market share in the region.
At the same time, competition in the energy storage sector is increasing. Chinese companies such as Sungrow have been expanding their presence globally, particularly in Europe.
