dropping 40 kg) was assigned to Marc Surer and Klaus Ludwig. The fortunes of Le Mans local Jean Rondeau had taken a big upward turn, selling several vehicles to customers. This enabled development of a Group C ground-effect car, the M482, and embarking on a full WEC season. Until ready, the team adapted the existing design to Group C spec, as the M382. They had the best possible start, winning the opening round at Monza with an updated M379C car, and came into the race as the leader in the championship. For Le Mans, three of the M382s were prepared, fitted with the bigger Cosworth DFL: the race-winning chassis would be driven by François Migault, Gordon Spice and Xavier Lapeyre. The premier car had Henri Pescarolo and Jean-Pierre Jaussaud (with five wins between them) while the third car had Rondeau himself with rally-specialist Jean Ragnotti. There were also three customer Rondeaux; Christian Bussi had an M382 with a 3.3-litre DFL, while those of Pierre Yver and former team-driver Jacky Haran were older M379Cs with 3-litre DFV engines. The small WM team also looked at running a WEC campaign, under the Secateva racing team set up by WM driver Roger Dorchy. Peugeot further developed the PRV engine, now up to 2850cc and putting out 540 bhp. But the fuel consumption of the twin-turbo engine had proven problematic in the early races. The new P82 had the drivetrain lowered to improve the centre of gravity and handling and could get up to 350 kp/h (220 mph) . Unlike all the other Group C cars the WMs were significantly smaller than the maximum dimensions and so had a far smaller frontal area that gave them their higher speed. Two cars were entered, with Dorchy and Guy Fréquelin in one and Jean-Daniel Raulet and Didier Theys in the other. Much like at WM, some of the R&D team at Mercedes-Benz got involved in Group C racing as a sideline. Swiss engineer Peter Sauber was working with composite-technology company Seger & Hoffmann, stepping up from their BMW M1 collaboration to Group C. They contacted the Mercedes technicians to develop their chassis design and aerodynamics. The resultant SHS C6 was fitted with a 3.96-litre Cosworth tuned by Heini Mader who got it to 540 bhp. Two were built, and sold to Gerhard Schneider (who had bought a Sauber-tuned M1) and Swiss slot-machine magnate Walter Brun. Both
