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 has reopened reservations for its long-delayed next-generation Roadster, asking buyers for a $50,000 deposit just days before an October 1 reveal event in Waco, Texas. The move revives a reservation process first launched in 2017 and later paused when Tesla pulled pricing from its website in 2021.
The reservation page requires an immediate $5,000 credit-card payment, described as fully refundable, followed by a $45,000 wire transfer due within 10 days, which is identical to what was expected previously. Reservations are not considered final until the wire clears.
The structure matches the 2017 terms Tesla used when it first collected deposits after unveiling a prototype. Tesla has not published a confirmed retail price or production start date on the order page.

The October 1 event is scheduled in Waco, about 90 minutes north of Tesla’s Austin headquarters and near SpaceX’s McGregor rocket test site. Tesla sent invitations to existing reservation holders and posted a “Go for launch” teaser on September 12.
The Federal Aviation Administration (FAA) established a temporary flight restriction over the McGregor area from September 18 through October 2, consistent with plans for a demonstration involving SpaceX-designed cold-gas thrusters. Elon Musk has previously described the optional package as enabling extreme acceleration or brief hovering. Tesla has said the event will include pricing, specifications, and production targets.
The second-generation Roadster was first shown in November 2017 during Tesla’s Semi launch. Musk promised production in 2020, with claimed performance of 0-60 mph in 1.9 seconds, more than 250 mph top speed, and roughly 620 miles of range.
Those targets have slipped repeatedly.
Tesla later pointed to 2022, 2023, 2024, and 2025-2026 before indicating production would not begin until 2027 or 2028 at Gigafactory Texas. Design work has continued, with reports of a sharper, Cybertruck-influenced look replacing the original curvy prototype.
Original reservation holders who paid $50,000 in 2017, or $250,000 for the Founders Series, have waited nearly nine years without a production car. Some high-profile customers canceled. Tesla’s decision to reopen orders now, after previously shutting them down, tests whether new buyers will commit substantial funds before seeing a finalized production vehicle. The October 1 event is intended to answer remaining questions about what those buyers will actually receive and when.
Tesla’s Full Self-Driving (Supervised) is heading to Czechia after the Czech Ministry of Transport recognised the Dutch RDW’s provisional type approval, making the country the seventh EU member state to clear the system for public roads. Tesla Europe announced on 21 September 2026 that “FSD Supervised is now approved in Czechia” and that rollout “will begin soon.”
The decision marks a notable reversal. Earlier in 2026, Prague had declined to automatically recognise the Netherlands’ April approval, citing concerns over speed-limit compliance, traffic-sign recognition and driver-attention monitoring, and arguing that a coordinated EU approach was preferable. Officials said months of expert review, talks with Tesla and other member states, and real-world data from countries already using the system resolved those issues.

“Safety remains the top priority,” the ministry stated.
FSD Supervised remains a Level 2 driver-assistance system: the driver must stay engaged and is legally responsible. Eligible vehicles need AI4, the company’s most up-to-date hardware version. Tesla is expected to push the feature over the air in the coming days, following the pattern seen after earlier national approvals.
Europe’s rollout began when Dutch regulator RDW issued a provisional EU type approval on 10 April 2026 after extensive testing. Mutual recognition then produced a rapid cascade: Lithuania (20 May), Estonia (29 May), Denmark (9 June), Belgium (10 June) and Slovenia (7 September). Czechia now completes that list of seven.
The approvals cover only a modest share of the EU population, but they add political weight ahead of a 6 October vote by the Technical Committee on Motor Vehicles. A qualified majority, at least 15 of 27 member states representing 65 percent of the EU population, could open the remaining markets, including large ones such as Germany, France, Italy and Spain that have so far preferred to wait for a bloc-wide decision.
For Czech Tesla owners, the immediate prize is access to the same supervised highway and city driving already available in the other six countries. For Tesla, each new market generates additional European driving data and strengthens the case that FSD Supervised can operate safely under the continent’s varied road rules. The Czech approval is therefore both a local milestone and another incremental step toward a wider European launch.
The Federal Aviation Administration (FAA) has established a Temporary Flight Restriction over SpaceX’s McGregor, Texas, rocket development and test facility, a move widely viewed as preparation for Tesla’s October 1 Roadster reveal. The restriction took effect September 18 and runs through October 2.
NOTAM FDC 6/3825 covers a 1.5-nautical-mile radius around the site near Waco and extends from the surface to 10,000 feet above ground level. The FAA cited hazards under 14 CFR 91.137(a)(3) and barred aircraft and drones from the zone. Tesla’s invitation to reservation holders already placed the event in Waco, about 20 minutes from McGregor, making the timing and location more than coincidental.

What stands out is the altitude. Typical recent TFRs at McGregor for engine static fires and component tests have used far lower ceilings, often around 2,000 feet. Raising the limit to 10,000 feet is unusually high even compared with some Starbase restrictions and signals operations that go beyond a standard ground-level engine test.
That extra airspace has fueled speculation about the long-promised SpaceX Package for the Roadster. Elon Musk has described cold-gas thrusters that could deliver sub-one-second 0-60 times and, more dramatically, brief lift-off. Reports earlier this year indicated Tesla planned a remote-controlled demonstration at McGregor in which the car would leave the ground with no one inside; spectators kept hundreds of yards away because of the noise.
The 10,000-foot envelope would give operators a large safety buffer even if the vehicle only hovers a short distance.
Tesla has not confirmed a flight demo. The company has only used the phrase “Go for launch” and posted a teaser image of the car on what looks like a launch pad. The TFR itself mentions only hazards. Still, closing airspace this high and this close to the reveal date strongly suggests the event will include more than a static display.
Whether the Roadster actually hovers on October 1 remains to be seen. What is certain is that the FAA has cleared a large vertical slice of Texas sky for whatever Tesla and SpaceX intend to show. Reservation holders heading to Waco will be among the first to find out if the car can do more than drive.
