Peugeot, 12 cylindres et diesel dans la même phrase : cette réalité automobile défie tous les codes – PassionAndCar.fr
Peugeot developed the 908 RC in 2006, a concept prestige sedan powered by a 5.5-liter V12 turbodiesel engine.
The vehicle’s powertrain delivered 700 horsepower and 1,200 Nm of torque. Measuring 5.12 meters in length, the four-door prototype was designed to integrate supercar-level mechanics into a luxury sedan format.
Technical Specifications and Performance
The 908 RC was engineered to showcase the capabilities of Peugeot’s HDi common-rail technology. Performance estimates for the prototype indicated a top speed exceeding 300 km/h. In acceleration tests, the vehicle was capable of covering a distance of 1,000 meters from a standing start in 22 seconds.

The development of the V12 turbodiesel configuration represented a departure from the manufacturer’s traditional engine layouts, utilizing high-capacity diesel mechanics to achieve performance benchmarks typically associated with high-end gasoline engines.
Strategic Objectives
The project served as a technical demonstration of the potential of HDi technology. By producing a vehicle with these specifications, Peugeot intended to signal a high-end offensive against the trio of dominant German luxury automakers.
The 908 RC remained a technical prototype and never entered commercial production.
