The definition of a boxy sports car is the Audi Quattro. The Audi Quattro Sport was born on rally tracks as a road going model to homologate for racing. The Quattro Sport featured a 2.1-liter straight five-cylinder engine with a turbocharger and 306 HP in street trim.
With a short wheelbase, light body panels, short ratio gearbox, and 306 horses, the road going Quattro Sport goes from 0 to 60 mph in just 4.8 seconds. But the essence of this car is that it brought Group B performance to the streets. It was an analog rally car that provided immense pleasure to the ones lucky enough to drive it to the limit.
