Other than stopping the driver by penetrating metal or glass, what are you thinking a round should do to stop a vehicle? If you are thinking a round penetrating an engine block, you will have to move up to rifle rounds, namely-armor piercing, .50 cals, etc. I'm sure pistol rounds can break radiators, fuel tanks, engine components, etc, but again, they just leave a mark on engine blocks.
I've seen training movies/videos which dispelled common myths of rifle/pistol/shotgun rounds, one being .357s being able to stop engines.....well these movies/videos show they don't even come close. Regular rounds and tracer rounds blowing up vehicle gas tanks like in movies.....nope. I haven't seen these since the '80s and '90s, but I wouldn't doubt there are similar videos on the net.
