@groupbcars: The Audi Sport quattro S1 E2 is one of the most extreme and recognizable rally cars in motorsport history. Introduced in late 1985 for the legendary Group B rally era, it featured a roaring 2.1-liter, 5-cylinder turbocharged engine that produced between 473 and 600 horsepower, aggressive aerodynamic wings, and a blisteringly fast 0-100 km/h time of 3.1 seconds. #audi #quattro #groupb #S1E2 #rally
