Race Groups
GROUP A 1960-1972
The oldest and perhaps most memory-stirring division, Group A is home to classic sports cars and prototypes from the early 1960's all the way through the 1970's.

GROUP B 1973-1982
Evoking the same emotion and memories of Group A with a little more turbo-power and wide-body aerodynamics, Group G spans from the mid-1970's to the early 1980's.
GROUP C 1980-1990
The prime of the IMSA GTP and Group C era is at the heart of this Group, not to mention some memorable GT and production-based race cars.
GROUP D 1994-2002
Historic but familiar, Group D has prototypes and GT cars from the mid-1990's all the way through the early 2000s.
GROUP E 2000-2018
The fastest and most contemporary class, Group E features prototypes and GT machines that raced at Daytona as recently as a decade ago.
GROUP F - 2000-2018
Due to the popularity of the current prototypes and GT machines we have expanded Group E. Group F will encompass the older generation of the Prototypes and GT machines.
GROUP G HSR CARS.
Home to the HSR classes that are not represented in the other six groups, Group G lets competitors with race cars that were never eligible to race at Daytona a chance to establish some new history.
Complementing the Classic 24 Hour will be HSR's signature Sprint Races & Endurance Series.
