The Peugeot 9X8 is a sports prototype racing car built by French car manufacturer Peugeot for the Le Mans Hypercar category in the FIA World Endurance Championship.

Peugeot states the 9X8’s name to be a combination of multiple elements: the 9 symbolizes the brand’s high-performance models, the X represents all-wheel drive and electric drive technologies, and the 8 corresponds to the brand’s contemporary models.

Succeeding the 905 and 908, the 9X8 was designed to take full advantage of the freedoms allowed by the new regulations for the Hypercar category. The first area to benefit from the new regulations is aerodynamics; the vehicle is allowed to have only one adjustable aerodynamic element without the FIA specifying what it should be, thus allowing Peugeot to do without the rear wing. The 9X8 is powered by a 500 kW (670 hp) twin-turbo 2.6 L V6 engine mated to a 7-speed sequential gearbox driving the rear wheels, while a 200 kW (270 hp) electric motor drives the front wheels.
