John Heinricy's SCCA T1 Grand Sport Corvette

GM’s Former Director of High Performance John Heinricy will be racing the Isotorque Phoenix Performance Corvette Grand Sport at the SCCA’s National Championship Runoffs at Road America this Sunday. Heinricy is six for seven in class wins when racing Corvettes at the Runoffs and owns 11 overall Runoff wins, the most of all active SCCA drivers.

National Champion Scott Tucker will be defending his T1 title with a Ferrari while 2009 third place finisher John Buttermore trades his Corvette in for a Dodge Viper.

The LS3 equipped Grand Sport Corvette Coupe was built by Phoenix Performance LLC of Phoenixville, Pa. Heinricy won the T1 class at the Runoffs tune-up weekend during Road America’s June Sprints weekend.

The SCCA’s National Championship Runoffs will be held Sunday morning on Road America’s 4.045-mile road course circuit. The T1 class will race at 9:30 am ET with live the race shown online at

Since retiring from GM in 2008, Heinricy has remained busy, consulting with Torvec, in Rochester, N.Y., helping the company develop the IsoTorque differential. He also serves as a test driver for Hennessey Performance in Sealy, TX.

Heinricy started second place but experienced transmission trouble just as the race went green. Competitors were forced to take evasive action to avoid him and seven cars were involved in a crash that red flagged the race. Heinricy was unable to complete a lap and earned a DNF.
