GM's John Heinricy retired, but hasn't disappeared just yet. He's now a consulting engineer for Hennessey and you can see him here taking the new 705-horsepower HRE ZR700 for a couple of seriously hot laps.

John Heinricy stepped down this past October from his position as Director of GM Performance Division, likely knowing that his group would be disbanded in the wake of the Carpocalypse. But all is not lost. Another performance guru with the same initials has brought him on as a consulting engineer to test the Corvette ZR1-based HPE ZR700. Should be fun considering this is the same guy who set the fastest production sedan lap time in a 2009 Cadillac CTS-V on the famed Nurburgring Nordschleife.

John Hennessey has gotten a bad wrap in recent times due to a supposed scandal involving a couple of his customers Dodge Vipers. The internet lit ablaze with this news, but here's proof that he's still considered to be one of the best in the business.

Maybe it's time for another visit out to the Lonestar Motor Park.
