The Classic 24 Hour returns this November to the banks of Daytona International Speedway. The event will comprise racing for HSR race groups and incorporate a round of the Masters Endurance Legends USA series. This grid caters for a broad range of cars and showcases endurance races from the Group C era of 1982 right up to their modern equivalents of 2016.

The featured marque at the 2020 24 Hour event will be BMW.

Classic 24 Hour 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.


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.
