On May 13, 2011, Grand Am announced that various changes would be made to the Daytona Prototypes for the 2012 season:

The greenhouse (cockpit) area will be nearly identical for all newly constructed cars. The roll cage will be narrower on each side of the car, although the driver's position will not change. There will be a one-inch zone throughout the greenhouse surface to allow for individual styling cues, including windshield implementation and window outlines. New minimum body cross-section provisions will give the new DPs a more upright front fascia and nose, rather than the more sloped layout of today's cars. This will allow manufacturers to add more design character to their cars, making them closer to their production cars while still offering the dramatic message embodied by a prototype. Flexibility has also been introduced into the rules for side bodywork, including production-derived sidepods and open vents behind the front wheels that will enable styling elements from street cars to be functional on the race cars. Additional changes
On May 27, 2011, it was announced that BMW was developing a new 4.5 liter V8 which debuted at the 2012 Daytona 24. The engine is primarily derived from that of the E92 generation BMW M3. On November 15, 2011, Chevrolet unveiled its new Corvette-inspired DP. It made its debut at the Daytona 24. Results
