The Porsche 959 is a sports car manufactured by Porsche from 1986 to 1989, first as a Group B rally car and later as a legal production car designed to satisfy FIA homologation regulations requiring that a minimum number of 200 street legal units be built.
In 1986, it held the title as the world's fastest street-legal production car. During its production run, it was hailed as the most technologically advanced road-going sports car ever built and the forerunner of all future super cars. It was one of the first high-performance vehicles to use an all-wheel drive system, providing the basis for Porsche's first all-wheel drive Carrera 4 model. In fact, it convinced Porsche executives of the system's viability so well that they chose to make all-wheel drive standard on all versions of the 911 Turbo starting with the 993 variant. In 2004, Sports Car International named the 959 number one on its list of Top Sports Cars of the 1980s.
