One thing that we like the most about Hennessey Performance, besides their huge obsession with horsepower, is the fact that they always put their money where their mouth is. They don’t just claim something, they will prove it to you by drag or dyno videos. In this video John Hennessey himself takes you for a ride in the latest product, the ZR750. Based on the Corvette ZR1, this beast makes nearly a 100 hp more than the standard car. OMG then!
