The designer of the iconic SWB Audi Sport Quattro of the 1980s has described the car as "bloody ugly".

Only 200 special homologation versions of the volume produced Quattro coupe were made and featured a turbocharged 2.1-litre alloy engine. Its wheelbase was shortened by 290mm and bulging arches, vents and rear spoiler were added to make it instantly recognisable.

Audi recently revealed a new Quattro concept, which, based on a shortened RS5 platform, follows the spirit of the 1984 version.
