John Heinricy, who retired after working with GM for 38-years, recently got behind the wheel of the 2009 Corvette ZR1 with a Hennessey ZR700 package.
The former head of GM Performance Division and chief engineer of the new 2009 Cadillac CTS-V and ZR1, tested his skills on the 705-hp ZR1 to see what Hennessey came up with.
The Hennessey ZR700 package allows the ZR1 go from 0 to 60 mph in 3.1 seconds with a top speed of 212 mph. A second package, known as the ZR750 makes a total of 755-hp and 730 lb-ft of torque. That allows the ZR1 to run from 0 to 60 in 2.9 seconds with a top speed of 217 mph. Since this is part 1 of the video, we’re guessing Heinricy will test the ZR750 in part 2.
