The 2011 Rolex 24 at Daytona Grand-Am race kicks off this weekend and several US racing teams are in the final preparation stage. One of them is the well-known tuner and racing team Turner Motorsports which will race once again in their self-prepared BMW M3 Coupe.
The Rolex 24 Hours of Daytona is, like the 24 Hours of Le Mans, an endurance race of man and machine to see who can traverse the longest distance in the alotted time. Many teams have tried and many have failed to survive the grueling conditions of the race. The series, typically dominated by Porsche and GM cars, had an abundance of Bavarians at the 2010 running of the Rolex 24 Hours of Daytona held in Daytona Beach, Florida.
To introduce us to their Rolex GT M3 race car, Turner Motorsport releases the timelapse below.
