Development

The preparation of the prototype trace back to the development of the Oreca 05. The Oreca 05 was developed with the consideration of what the factory knew about the new technical rules for the LMP2 class in the

for 2017. Taking knowledge from the Oreca 05's performance, the French team decided to develop a new car, and based it around the predecessor. Oreca's goal was to maximize the performance by focusing on the energy and resource usage. The team opted to use this strategy not only to build a car based on a proven predecessor, but also to allow teams update their Oreca 05's within reason to costs. The chassis of the Oreca 07 is mainly based on the 05, with the monocoque being not focused on much with the car. The Oreca 07 internals come equipped with a Gibson GK-428 V8 engine. The car performed its first factory shakedown test in late October 2016 at Circuit Paul Ricard. Current orders see confirmed production until the end of April 2022, at which point well over 90 chassis will have been produced, including 8 chassis for the Acura ARX-05 DPi programme and 9 updates for the Oreca 05, but not including the
