Audi created a stir at the 1991 Frankfurt Motor Show, presenting the Audi Quattro Spyder Concept - a prototype previewing a possible mid-engined sports car for production. The quattro nameplate was already recognisable thanks to the original Audi Quattro (1980-1991) and the subsequent racecar which enjoyed great success in the '80s. A high-end sports car would help Audi strengthen its image as a premium carmaker.
