I've carpooled in a Prius and a Honda Civic Hybrid. Both of those cars seemed to be extremely capable of accelerating to pass other cars on the freeway. I was riding in the Prius one time and my friend was complaining about the Prius being slow, when we got stuck behind a car going 60 mph. Beep boop, he idly jumped up to 80, passed the guy, dropped back to 67, and went back to complaining that his car was slow.

I was terribly impressed; my car would've had to put more work in to do that.
