The original Quattro model, first shown in 1980, is also commonly referred to as the Ur-Quattro - the "Ur-" (German for "primordial", "original", or "first of its kind"). It was the first rally car to take advantage of the then-recently changed rules which allowed the use of four-wheel drive in competition racing. It won competition after competition for the next two years.
The original engine was the 2,144 cc (131 cu in) (2.1 L), inline-5-cylinder 10 valve SOHC, it was eventually modified to a 2,226 cc (136 cu in) (2.2 L) inline-5 10 valve, and finally in 1989, it was then changed to a 2,226 cc (136 cu in) inline-5 20v (2.2 L 20v) DOHC setup producing 162 kW (220 PS; 217 bhp), and a top speed of 230 km/h (143 mph).
Quattro car production was 11,452 vehicles over the period 1980–1991, and through this 11 year production span, despite some touch-ups, there were no major changes in the visual design of the vehicle. (en.wikipedia.org)
