The Oreca 07 is a Le Mans Prototype built by French manufacturer Oreca to meet the 2017 FIA and ACO LMP2 regulations.^[1] It made its official race debut in the opening round of the 2017 IMSA WeatherTech SportsCar Championship, the 24 Hours of Daytona,^[2] and its FIA World Endurance Championship debut at the 2017 6 Hours of Silverstone. The car is the successor to the Oreca 05.

Development

Oreca 07 with LMP2 Endurance Trophy

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 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. 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.^[1][3]

The car performed its first factory shakedown test in late October 2016 at Circuit Paul Ricard.^[3]

Alpine A470

French car manufacturer Alpine raced the Alpine A470 in the FIA World Endurance Championship. This car is technically identical to the Oreca 07, using the same chassis and internals, with Alpine branding. This is the successor to the Alpine A460, which Alpine raced and won the LMP2 category for the 2016 FIA World Endurance Championship season.^[4]

Acura ARX-05

A variation of the prototype, the Acura ARX-05, was created for IMSA's WeatherTech SportsCar Championship Prototype class under the DPi regulations. The car was developed in partnership with Honda Performance Development and Oreca.^[5] The powerplant of the vehicle is a production-based 3.5 litre V6 twin-turbo Acura AR35TT. Other alterations from the 07 include Acura-specific bodywork.

A pair of cars will be campaigned in the 2018 WeatherTech SportsCar Championship under the Team Penske banner.^[6]
