It has been a while since a GTR endurance series was held in LFS, but the CityLiga 10 Hours of Westhill International prooved that there is still a lot of interest in endurance racing in the GTR category and in LFS in general. Still, endurance racing is spiced up by a multi-class structure.
The Open Endurance Cup will provide several options to compete for class and/or race wins in four classes: The TBOs, the LRFs, the NGTs and the GTRs. Still all classes score to the same overall classification, with a points allocation based on the number of competitors per class using the system of the VLN Langstreckenmeisterschaft Nürburgring.

The OEC One will see the following schedule:

1. 4 Hours of Westhill National reversed (Sun 13 Sep 2015: 14:45UTC qualifying, 16:00UTC race)
   
2. 4 Hours of Kyoto Ring Grand Prix Long (Sun 11 Oct 2015: 14:45UTC qualifying, 16:00UTC race)
   
3. 6 Hours of Aston Historic (Sun 8 Nov 2015: 13:45UTC qualifying, 15:00UTC race)
   

Sign-Ups start on Thu 13 Aug 2015 at 14:45UTC. Further details will be finalised and released before.
