NASCAR, the inventory automobile racing sanctioning physique identified for its high-octane occasions throughout the USA, is taking a major step towards a greener future. In July, throughout the Chicago Avenue Race occasion, NASCAR unveiled a prototype battery-powered race automobile that marks the start of its push to decarbonize motorsports. This transfer is a part of NASCAR’s broader technique to realize net-zero emissions by 2035.
The electrical prototype represents a collaborative effort between NASCAR and its conventional Unique Gear Producer (OEM) companions—Chevrolet, Ford, and Toyota—together with ABB, a worldwide know-how chief. Constructed by NASCAR engineers, the automobile options three 6-Section motors from Stohl Superior Analysis and Improvement, an Austrian specialist in electrical automobile powertrains. These motors collectively produce 1,000 kilowatts at peak energy, equal to roughly 1,300 horsepower. The power is equipped by a 78-kilowatt-hour liquid-cooled lithium-ion battery, working at 756 volts, although the particular battery chemistry stays a intently guarded secret.
C.J. Tobin, Senior Engineer of Automobile Programs at NASCAR and the lead engineer on the EV prototype venture, defined the motivation behind the event. He informed IEEE Spectrum that “The push for electrical autos is continuous to develop, and once we began this venture one and a half years in the past, that development was speedy. We wished to showcase our capacity to place an electrical inventory automobile on the observe in collaboration with our OEM companions. Our racing collection have all the time been a platform for OEMs to showcase their inventory vehicles, and that is simply one other device for them to display what they’ll supply to the general public.”
Eleftheria Kontou, a professor of civil and environmental engineering on the College of Illinois Urbana-Champaign whose main analysis focus is transportation engineering, stated in an interview that “It was a wonderful introduction of the brand new know-how to NASCAR followers, and I hope that the followers might be open to seeing extra improvements in that area.”

The electrical race automobile is not only about pace; it’s additionally about sustainability. The automobile’s physique panels are produced from ampliTex, a sustainable flax-based composite equipped by Bcomp, a Swiss producer specializing in composites produced from pure fibers. AmpliTex is lighter, extra moldable, and extra sturdy than conventional supplies like metal or aluminum, making the automobile extra environment friendly and aerodynamic.
Regenerative braking is one other key characteristic of the electrical race automobile. Because it slows down, the automobile can convert a few of its kinetic power into electrical cost that feeds again into the battery. This characteristic most advantageous on highway programs just like the one in Chicago and on brief oval tracks like Martinsville Speedway in Virginia.
“The Chicago Avenue Race was an amazing introduction for the EV prototype as a result of it occurs in a real-world setup the place electrical autos are inclined to thrive,” says Kontou, who additionally serves on the Steering Committee of the Illinois Alliance for Clear Transportation. “[It was a good venue for the car’s unveiling] as a result of navigating the course requires extra braking than is typical at many speedway tracks.”
Although the electrical prototype is a component of a bigger NASCAR sustainability initiative, “There are not any plans to make use of the electrical automobile in competitors right now,” a spokesman stated. “The inner combustion engine performs an necessary function in NASCAR and there are not any plans to maneuver away from that.” So, die-hard stock-car racing followers can nonetheless anticipate the sounds and smells of V-8 engines burning gasoline as they hurtle round tracks and thru road programs.

In its sustainability efforts, NASCAR lags nicely behind Method One, its largest rival atop the world’s motorsports hierarchy. Since 2014, Method One’s mother or father group, the Fédération Internationale de l’Car (FIA), has had an all-electric racing spinoff, referred to as Method E. For the present season, which started in July, the ABB FIA Method E World Championship collection boasts 11 groups competing in 17 races. This yr’s races characteristic the league’s third technology of electrical race vehicles, and a fourth technology is deliberate for introduction in 2026.
Requested how NASCAR plans to observe by means of on its pledge to make its core operations net-zero emissions by its self-imposed goal date, the spokesman pointed to modifications that might counterbalance the output of conventional inventory vehicles, that are infamous for his or her poor gas effectivity and excessive carbon emissions. These embody 100% renewable electrical energy at NASCAR-owned racetracks and services, and tradeoffs akin to recycling and on-site charging stations to be used by followers with EVs.
The spokesman additionally famous that NASCAR and its OEM companions are growing racing gas that’s extra sustainable in mild of the truth that inventory vehicles devour, on common, about 47 liters for each 100 km they drive (5 miles per gallon). For comparability, U.S. federal regulators introduced in June that they might start implementing an industry-wide fleet common of roughly 5.6 liters per 100 kilometers (50.4 miles per gallon) for mannequin yr 2031 and past. Thankfully for NASCAR, race vehicles are exempt from fuel-efficiency and tailpipe-emissions guidelines.
Whereas some could also be tempted to check NASCAR’s prototype racer with the vehicles featured within the ABB FIA Method E World Championship, Tobin emphasised that NASCAR’s method in designing the prototype was distinct. “Outdoors of us seeing that there was a collection on the market racing electrical autos and seeing how issues have been run with Method E, we leaned closely on our OEMs and went with what they wished to see at the moment,” he stated.
The apparently sluggish transition to electrical autos in NASCAR is seen by some within the group as each a response to environmental issues and a proactive transfer to remain forward of potential laws that might threaten the way forward for motorsports. “NASCAR and our OEM companions need to be within the driver’s seat, irrespective of the place we’re going,” says Tobin. “With the event of [the NextGen EV prototype], we wished to showcase the modularity of the chassis and what powertrains we are able to construct upon it—whether or not that be various fuels, battery electrical energy, or one thing unexpected sooner or later…We need to proceed to push the envelope.”
