Generally they race at over 300 miles per hour.  Some tracks are shorter than others, but the longest track currently is 1,500 miles.  That translates to about 205 mph.  Since the cars can handle a lot of acceleration, they’re often hitting speeds above that in corners, though they’re also constrained by the track.
