Video: John Heinricy testing the705-hp Hennessey ZR1

As if the Corvette ZR1-based 705 hp Hennessey ZR700 wasn’t enough to make us drool already, now it’s getting the blessing from the godfather of C6 Corvette, John Heinricy. After Heinricy retired from the head of GM’s performance division (he piloted the CTS-V to victory against the BMW M5,) he went to work for Hennessey as a consultant. Watch as Heinricy gives the Hennessey a work out.
