In Austria in 1980, just a year after four-wheel drive cars became eligible to compete in the WRC, Audi debuted the first Quattro rally car and forever changed the sport. Over the next half of the decade (and onwards, if you count the Pikes Peak specials), these Audis would be subjected to a period of rapid iterative evolution that led to the short-wheelbase Sport Quattro models that helped define the infamously fast and dangerous era of Group B rallying. The relatively lax nature of the Group B regulations gave rise to a number of downright ferocious cars from Audi’s competitors (most notable being Lancia and Peugeot), and while it was not the most successful nor technologically advanced of these top tier cars by the end of the Group B era, the Sport Quattro is a worthy poster child for the lot of them—being first to the punch has its advantages.
