Tesla will remove performance limiting algorithm from cars in next software update

Published

on

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.

Elon Musk handed Grok something no other AI company can get their hands on

Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.

Artistic concept rendering of SpaceX data being incorporated into a Grok AI model

Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.

The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.

Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.

Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.

Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.

Tesla expands ridesharing service in California to new hotspot

Published

Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.

The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.

The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.

UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch

This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.

The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.

Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.

The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
