 The car was designed "in record time" according to Oreca Technical Director David Floury.The car only began testing in April 2014 and was not ready for the first race of the FIA WEC season, the 6 Hours of Silverstone, therefore Rebellion had to race with the two existing Lola B12/80s for the Silverstone race before switching to the R-Ones for round 2 at Spa-Francorchamps.The 2014 6 Hours of Spa-Francorchamps was the public début of the Rebellion R-One.
