1986 Audi Quattro proto Dakar
History and strong points
History Palmares: 1986 1987 Rally de l’Atlas Paris – Dakar Rally de l’Atlas Paris - Dakar The first prototype is developed in 1985 using a Range Rover-derived chassis with reduced rear overhang and reinforcements in the suspension attachment points; struts and a Panhard bar on the rear deck are added to the rigid axles. The fiberglass and Kevlar body is bolted to the frame with rubber pads to absorb shocks; the front and rear bonnets are fully removable. The engine is the classic Rover 8V 3500cc boosted to 230CV at 5400 rpm. The weight distribution is 50% on the two axes. The power supply, exhaust and transmission have been modified. The cooling system has been upgraded with a new heat exchanger. The suspensions are self-levelling pneumatic with four air springs, replacing the coil springs, connected to a power supply circuit controlled by the navigator. The car took part in the Paris-Dakar and the Rallye de l 'Atlas in 1986; on the way back, some changes were made by adding the fiberglass doors, a new dashboard and a new front hood. Franco De Paoli takes part in the Rallye de l'Atlas and the Paris-Dakar in 1987 with this new updated version. In total 5 prototypes with different characteristics are produced.
