Oreca builds "R13" LMP1 for Rebellion Racing

[Kristof]

Rebellion Racing and Oreca confirmed their partnership for its return to the LMP1 class in the FIA World Endurance Championship this season. It's a continuation of a long time partnership between the team and the manufacturer, as Oreca also designed and built the Rebellion R-One and Rebellion won the 2017 LMP2 title with the Oreca 07.
