NASCAR, the inventory automotive racing sanctioning physique recognized for its high-octane occasions throughout the USA, is taking a major step towards a greener future. In July, in the course of the Chicago Avenue Race occasion, NASCAR unveiled a prototype battery-powered race automotive that marks the start of its push to decarbonize motorsports. This transfer is a part of NASCAR’s broader technique to attain 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 expertise chief. Constructed by NASCAR engineers, the automotive options three 6-Section motors from Stohl Superior Analysis and Improvement, an Austrian specialist in electrical car powertrains. These motors collectively produce 1,000 kilowatts at peak energy, equal to roughly 1,300 horsepower. The power is provided 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 Techniques at NASCAR and the lead engineer on the EV prototype venture, defined the motivation behind the event. He instructed IEEE Spectrum that “The push for electrical automobiles is continuous to develop, and after we began this venture one and a half years in the past, that progress was fast. We wished to showcase our skill to place an electrical inventory automotive on the observe in collaboration with our OEM companions. Our racing sequence have all the time been a platform for OEMs to showcase their inventory vehicles, and that is simply one other instrument for them to show what they will provide to the general public.”
Eleftheria Kontou, a professor of civil and environmental engineering on the College of Illinois Urbana-Champaign whose major analysis focus is transportation engineering, mentioned in an interview that “It was a superb introduction of the brand new expertise to NASCAR followers, and I hope that the followers will likely be open to seeing extra improvements in that area.”

The electrical race automotive isn’t just about velocity; it’s additionally about sustainability. The automotive’s physique panels are created from ampliTex, a sustainable flax-based composite provided by Bcomp, a Swiss producer specializing in composites created from pure fibers. AmpliTex is lighter, extra moldable, and extra sturdy than conventional supplies like metal or aluminum, making the automotive extra environment friendly and aerodynamic.
Regenerative braking is one other key characteristic of the electrical race automotive. Because it slows down, the automotive 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 quick oval tracks like Martinsville Speedway in Virginia.
“The Chicago Avenue Race was an excellent introduction for the EV prototype as a result of it occurs in a real-world setup the place electrical automobiles are likely 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 an element of a bigger NASCAR sustainability initiative, “There are not any plans to make use of the electrical car in competitors presently,” a spokesman mentioned. “The interior combustion engine performs an vital position 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 effectively behind Components One, its largest rival atop the world’s motorsports hierarchy. Since 2014, Components One’s father or mother group, the Fédération Internationale de l’Vehicle (FIA), has had an all-electric racing spinoff, referred to as Components E. For the present season, which started in July, the ABB FIA Components E World Championship sequence boasts 11 groups competing in 17 races. This 12 months’s races characteristic the league’s third era of electrical race vehicles, and a fourth era is deliberate for introduction in 2026.
Requested how NASCAR plans to observe via on its pledge to make its core operations net-zero emissions by its self-imposed goal date, the spokesman pointed to adjustments that will counterbalance the output of conventional inventory vehicles, that are infamous for his or her poor gasoline effectivity and excessive carbon emissions. These embrace 100% renewable electrical energy at NASCAR-owned racetracks and services, and tradeoffs similar 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 creating racing gasoline that’s extra sustainable in gentle 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 12 months 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 Components E World Championship, Tobin emphasised that NASCAR’s strategy in designing the prototype was distinct. “Outdoors of us seeing that there was a sequence on the market racing electrical automobiles and seeing how issues had been run with Components E, we leaned closely on our OEMs and went with what they wished to see at the moment,” he mentioned.
The apparently gradual transition to electrical automobiles in NASCAR is seen by some within the group as each a response to environmental considerations 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 will construct upon it—whether or not that be different fuels, battery electrical energy, or one thing unexpected sooner or later…We need to proceed to push the envelope.”
