Here at Autoblog we've been fortunate enough to have two separate opportunities to drive what is officially known as the Milford Road Course. Informally, the facility is better known as the Lutz-ring. Early this decade when Bob Lutz was lured out of retirement to provide guidance to the product development staff at General Motors he quickly came to the realization that despite all of the different test surfaces at the Milford Proving ground there was no proper facility for evaluating the limit handling performance of its vehicles.
Under Lutz's prodding the development staff led by Jim Mero designed a 3 mile, 17 turn course where 97 percent of every lap is spent undergoing lateral acceleration to one side or another. The facility is used for both handling evaluation and development and as part of the durability cycle for new GM vehicles. We shot some footage the other day while driving in the Corvette Grand Sport and you can follow along for a lap of the Lutz-ring after the jump.
