This year marks the 30th birthday of Audi’s now famous quattro all-wheel drive system. The short-wheelbase plastic-bodied extreme machine called the Sport Quattro or Ur Quattro serves as the source of inspiration for the Audi Quatto concept, which will be unveiled tomorrow at the 2010 Paris show.
Loosely based on the Audi RS5, the Audi Quattro concept sits on a wheelbase that has been shorted by almost 6 inches. The rear overhang was shortened by 7.9 inches, and the roofline was lowered by 1.6 inches. Together, these reductions add up to a much tighter package and more muscular proportions. To help bring the weight down to similar weight as the Sport Quattro Audi replaced the steel body of the production RS5 with a custom aluminum spaceframe architecture clad with carbon fiber panels. The RS5’s V8 and dual-clutch transmission was also swapped out for a turbocharged five-cylinder and a manual six-speed gearbox to further reducing weight.
