Last September, Buick entered a Regal GS in the Silver State Classic Challenge in Nevada with lead development engineer Bill Rietow at the wheel and GS powertrain engineer John Townsend as navigator. The duo won the 120-mph class of the of the same open road course, which sets the team up to enter this month’s Nevada Open Road Challenge on May 20.
This time around, the Regal GS will compete against world class sports cars in the more difficult 135-mph class. The event takes place on a remote 90-mile stretch of Nevada State Highway 318. The GS itself is a stock 2012 model, with slight modifications limited to safety equipment such as a roll hoop and five-point harness seat belts, as well as data collection computers that are necessary for contention.
