NASCAR recently unveiled its first electric racecar prototype at the Chicago Street Race, marking a significant step toward its goal of going all-electric by 2035. This $1.5 million prototype, developed in partnership with ABB, Chevrolet, Ford, and Toyota, is part of the NASCAR Impact program aimed at reducing carbon emissions. The initiative seeks to gauge fan interest in electric racing and its future potential.
Tested by NASCAR driver David Ragan at Martinsville Speedway in Virginia, the electric racecar demonstrated impressive performance, coming within two-tenths of the average time of a V8-powered NASCAR racer. Despite having twice the acceleration and remarkable braking ability, the electric car’s overall weight limits its speed in corners.
Ragan noted that while he could have pushed the car faster, the current focus is on collecting comprehensive test data rather than risking hardware damage.
The prototype, built on a modified Next Gen chassis, features three STARD UHP 6-Phase motors—one at the front and two at the rear—producing a peak output of 1,000 kW.
These motors are powered by a liquid-cooled 78 kWh battery, with additional energy derived from regenerative braking. This technology converts kinetic energy from braking into extra power, enhancing the car’s efficiency.
Sustainability extends beyond the powertrain; The car’s body is made from a flax-based composite material, and many components, including the steering wheel, suspension, brakes, and wheels, are repurposed from a 2022 NASCAR Cup Series car.
However, unlike traditional gas-powered V8s, the electric racecar lacks the iconic roar, a feature NASCAR plans to replicate using artificial sound through an exterior speaker.
This prototype represents NASCAR’s commitment to sustainable racing, aligning with broader trends in motorsports like Formula-1’s shift toward sustainable fuels and Formula-E’s focus on clean racing.
