Audi Sport quattro

With its wheelbase shortened by a meaningful 12.6 inches between the B- and C-pillars, the Audi Sport quattro was not only significantly shorter than the standard Quattro found in showrooms, but its steel monocoque shell also featured numerous GRP and carbon-kevlar panels to further trim weight. As such, there was very little shared with serial production Audis. By the end of the production in 1984, Audi had produced 224 examples of what remains as one of the great homologation specials of the 1980s.
