About two days ago we brought you a video of retired John Heinricy taking the 2009 Corvette ZR1 with a Hennessey ZR700 package around a track. At first we thought the former head of GM’s Performance Division was just having some fun while feeding his need for speed. Well, it seems like Heinricy and Hennessey are up to something more… much more.

Apparently Heinricy, who drove the Cadillac CTS-V around the Nurburgring in a lap time of 7:59.32, is working with Hennessey Performance to take the Corvette ZR1 back to Green Hell for another crack at a record breaking time. The production version of the Corvette ZR1 currently sites in fifth-place in the world of Nurburgring lap times with 7:26.4 under its belt.

Heinricy and Hennessey are now planning to head back to the Nurburgring with a modified Corvette ZR1 with a 705-hp ZR700 Hennessey package under the hood. The ZR700 allows the Corvette ZR1 to go from 0 to 60 mph in 3.1 seconds with a top speed of 212 mph.

Check out these renderings of what the finished ZR700 Corvette ZR1 will look like when it heads to Germany.

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.
