NASCAR's EV prototype: How it differs from the Next Gen Cup car

On Saturday in Chicago, NASCAR unveiled its electric vehicle prototype race car in a new partnership with ABB.

The car isn't likely to ever see actual competition, but it part of the “NASCAR Impact” initiative, which is the sanctioning body’s platform to advance sustainability in electrification. The series plans to reduce its own carbon footprint to zero across its core operations by 2035.

John Probst, NASCAR’s senior vice president and chief racing development officer, said of the EV project: “As you know, we look towards net zero operating emissions for us by 2035, so at this point, I’m not sitting here saying we’re going to announce a series. That’s not what this is about.”

Instead, Probst said, the EV prototype is about “exploring what our future could be.”

“We built this car. We put it on track. That is our point, is to learn,” he said. “We’ll have a story tell as we learn. And we’ll be in the driver’s seat wherever our future takes us."
