Oreca 07 turned out to be the car of choice for LMP2 teams, finding more buyers every year, who switched to the chassis from the previously purchased ones of other brands.
The Oreca 05 was developed with the consideration of what the factory knew about the new technical rules for the LMP2 class in the FIA World Endurance Championship 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.
[1][7] The car performed its first factory shakedown test in late October 2016 at Circuit Paul Ricard.
[7] 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 Rebellion R-One (based on the 05) or Rebellion R13 (based on the 07) – (or indeed the grandfathered Alpine A480).
[8] The following month, chassis #100 (though technically the 99th due to skipping #13) was delivered to Cool Racing for the 2022 24 Hours of Le Mans, and will eventually be displayed at the company's factory showroom.
