FYI: General Motors (GM) has filed a patent for an innovative "endurance mode" aimed at extending the range of electric vehicles (EVs) during competitive races.
GM’s New Patent to Boost Electric Vehicle Performance in Races
General Motors has recently filed a patent for a novel "endurance mode" designed to enhance the range and efficiency of electric vehicles (EVs) during races. This patent, officially published by the United States Patent and Trademark Office (USPTO) on August 22, traces its origins to an early 2023 filing by GM. The idea centers around configuring the on-board controller to ensure vehicles complete a predetermined number of laps at a steady pace, all while avoiding performance degradation or running out of charge when speeding.
How It Works
- Controller Analysis: The on-board controller has the ability to evaluate several factors, such as the vehicle’s layout and the driver’s inputs, to anticipate when the battery and other components may overheat.
- Temperature Management: To maintain optimal performance, the controller can proactively manage power output to keep components within safe temperature limits.
This strategic approach ensures drivers can maintain a certain performance level without risking the vehicle’s efficiency or longevity.

Potential Qualifying Mode
GM is also exploring an alternative "qualifying mode," which would temporarily allow the EVs to unleash maximum power for short bursts. This concept, mentioned in an earlier patent application filed in April, could significantly benefit high-performance EVs. Mark Reuss, President of GM, teased the possibility of an electric Corvette during a 2022 interview, hinting that such advanced modes could one day feature in these top-tier vehicles.

Existing Technologies and Comparisons
GM is not alone in this high-performance EV space. Other brands have already begun implementing similar technologies:
- Hyundai Ioniq 5 N: Offers Endurance and Sprint settings in its N Race mode.
- Lucid Air Sapphire: Features Drag Strip, Endurance, and Hot Lap modes within its Track setting.
Additionally, Formula E race cars, known for their advanced electric capabilities, have an inherent energy management system. These cars are equipped with less energy capacity than needed for a complete race at full speed, necessitating energy conservation strategies by the teams.
Conclusion
As General Motors continues to innovate and push the boundaries of electric vehicle performance, the anticipated "endurance mode" represents a significant step forward. Coupled with potential advancements like the "qualifying mode," these innovations could redefine the capabilities of future high-performance EVs.
