The Sport Quattro is an Evolution of the Audi Quattro which took over the results of world class rallying. The Sport, with the marque's celebrated permanent 4-wheel drive transmission, was one of just 200 Homologation special versions of the volume-produced Quattro coupe produced in 1983 and one of only approximately 20 assigned by the factory for competition work. These supercars were only available in left-hand drive and were equipped with an all new 20-valve alloy block. They can be easily identified by their shortness, the wheelbase being 29cm shorter than the standard Quattro fixed head (similar in fact to arch rival from those Group B car days, the MG Metro 6R4), some seriously steroidal bulging wheelarches, rear wing vents and single square lamps. Chassis number 108 was initially prepared by the works Competition Department. Producing a mightily impressive 530bhp, the KKK 27 turbocharged, 5-cylinder, 2144cc power unit has been modified from the original 2122cc capacity motor by Leimans of Liechtenstein. Coolers for oil and fuel were situated below the huge rear wing and in the boot, while most of the external add-on panels - front, bonnet, boot and rear spoiler - were of Kevlar composite material for greater lightness and strength.
