THE GRAND AMERICAN Road Racing Association Daytona Prototypes are entering their seventh season in 2009 as the featured class of the Rolex Sports Car Series.
Daytona Prototypes are sleek, full-bodied race cars that match auto manufacturers in the evolution of prototype sports cars, featuring powerplants that are offered to the public.
Engines for the Daytona Prototypes will be approved in two categories. Normally aspirated production 6- or 8-cylinder, 245 CID powerplants are open to modification. The second category, for V8 engines up to 305 CID, will have tightly controlled specifications and must be run as produced. The Lexus entries, which fall in the latter category, feature 5.0-liter, V8 engines that produce 500 hp at 7000 rpm.
