2015 Aston 24 Hours

The 2015 Aston 24 Hours was the first running of this special 24-hour endurance event, held on the Aston Grand Touring course on October 17 and 18, 2015. It was organized by NVRT Holdings, the company behind Rejects of LFS, a month after the 2015 Rejects of LFS season finale. The RoLFS season had been marred by the death of Nobushige Fukuda at the penultimate race of the season, an event that ultimately led to the dissolving of RoLFS completely and the creation of a completely new series called the International Formula Reject Challenge. This put the future of Aston 24 Hours in doubt before even the first running of it had taken place, but in early 2016 it was announced that all rights to the event had been sold to Finanz-Sichereit Konglomerat and the event would take place in the future as well.

The race was won by Aero Kings Racing, who fielded George Bruno, Marco Bizzarri, and Calvin Brooks as their drivers. During the race, three cars were disqualified for various infringements - Jones Racing's and Ural Racing's cars for ignoring separate stop-and-go penalties, an error commonly seen during the regular season, and the Winton Racing's car for running a damaged car which ultimately caused multiple collisions.

Entry list
The entry list was capped at 20 entrants, with each team required to have three drivers to share the driving duties. The teams chose their cars from three powerful GTR touring cars, with each model limited to supply a maximum of seven teams.
