The year 2003 was a landmark year in the history of Grand Am Rolex Sports Car Series and would stay there for years and years to come as it was the season when the much awaited Daytona Prototypes made their much hyped debut on the Rolex Sports Series circuit. As was to become the custom later on, the season started off at the historically significant and legendary Rolex 24 At Daytona and the Daytona Prototypes finally made it to the racetracks. The 2003 Rolex 24 At Daytona witnessed the debut of the Daytona Prototypes with six cars entering the fray for the first time ever in the Grand Am Rolex Sports Car Series. The six different Daytona Prototypes were in fact representing only five teams and there were only three chassis manufacturers, a situation which in few years to come was to change drastically with more and more teams vying to become a part of the famous racing circuit of the world of motorsports.
The Daytona Prototypes had a very interesting debut, something which was exactly opposite to what everyone was hoping for. Considering the fact that Rolex 24 At Daytona in any case is counted as the most difficult of endurance races, that there would be some initial hiccups was not something that was not a concern from the start, but the way some of the Daytona Prototypes behaved and performed was really unexpected. Darren Law was on the wheels of the G&W Motorsports BMW Picchio which within the first fifteen minutes of the race started facing issues related to overheating. The situation was worse in the case of Forest Barber and Terry Borcheller driven Bell Motorsports Chevrolet Doran which could not survive the rigors of the 24 hours of Daytona racing and barely managed to complete 67 laps at the race tracks.
More was to come as David Donohue and Mike Borkowski driven No 58 Red Bull Brumos Porsche Fabcar even though being the dominating car in the first six hours of racing lost its engine all of sudden. More or less similar fate was in store for the No 88 Ford Multimatic which kept loosing time, every now and then, due to its broken throttle cable. The No 66 The Racers Group Porsche GT3 with an impressive list of drivers like Kevin Buckler, Michael Schrom, Timo Bernhard and Jorg Bergmeister was the eventual winner of the overall honors in the end. The win for the team was made even more important since it also coincided with the 30th anniversary of the 1973 Daytona 24 victory of Hurley Haywood and Peter Greggs. The prestigious first crown in the Daytona Prototype class was captured by the team of David Brabham, David Empringham and Scott Maxwell which raced fast enough to be placed a remarkable 4th overall in the race.
Another high point of the 2003 Grand Am Rolex Sports Car Series was increasing the number of races to 12 and reducing the number of classes to four. For a good part of the season there were only four Daytona Prototypes with the number rising to five in June and seven in August, both times at Watkins Glen. The final race of the season at Daytona had a good ten cars starting the grid. Eventually overall the first season of Daytona Retypes was not exactly the kind of debut season everyone had hoped for but it did build a lot of promise for the Grand Am Rolex Sports Car Series seasons to come.
