Rondeau M482 '84-87

Powered by Ford Cosworth DFL V8/90° 4v DOHC 3955 cc N/A

Dubbed the M482, it was created with the help of aerodynamicist Max Sardou. His involvement was crucial to the project as sophisticated 'ground effect' aerodynamics would become a key part in the design of all Group C cars. The Frenchman was one of the ground effect pioneers and had already helped design the Lola T600 GTP racer a year earlier.
Underneath the carbon-fibre composite with Nomex sandwich body panels, the M482 featured an all-new aluminium monocoque that used the Cosworth DFL engine as a fully stressed members. To allow for a clean airflow through the tunnels, the rear suspension was mounted in-board with the springs and dampers actuated by rockers.
Entered alongside the interim M382s, the first M482 had a disastrous debut.

The M482 was the end of the line for the brief but successful spell for Rondeau as a manufacturer. With the likes of Porsche, Lancia and Jaguar entering the Group C ranks, there no longer was a place for a privateer like Jean Rondeau at the highest level of sports car racing.
