 CBS's Matt Piper. NASCAR introduced its first electric race car to fans this weekend in Chicago. Listen to this. The $1.5 million prototype is a lot quieter than your average race car with three electric motors, two in the front, one in the back. NASCAR says it's still gauging interest, but says the EV is part of a broader sustainability plan. It aims to cut operating emissions to net zero by 2035. Monica Ricks, CBS News.
