Holy. Crap. It’s not like the regular ZR1 is slow. But Hennessey’s new Vette looks?and sounds?positively evil. I don’t think setting the record in a modded car means anything, but then again setting it in a stock car probably doesn’t mean anything either. That said, I think I’d like to repeat my earlier statement: Holy. Crap. The full stats are below.
