Oreca 05

The Oreca 05 is a Le Mans Prototype built by Oreca in 2015. The car was designed to compete in the LMP2 class. The car's first win came at the 2015 24 Hours of Le Mans by Hong Kong–based team KCMG. A closed-top design, it incorporates several new mechanical and safety features not used in the Oreca 03 car. Zylon anti-intrusion panels are built into the frame that prevent any mechanical components from coming into the chassis in the event of an accident. Since Oreca 05 shares the same monocoque with Rebellion R-One in LMP1 class which allowed only 1,900 mm (74.8 in) width after 2014, so the car also 1,900 mm (74.8 in) width while most other LMP2 in 2010-2016 are built to reach maximum 2,000 mm (78.7 in) width as LMP2 regulation allowed. The 05 has an electrical power steering system and an improved gearbox.

As a majority of existing cars being rebuilt into the 07, only three 05s, including the Alpine, are known to currently exist in its original form.
