The Audi quattro revolutionised the Rally World Championships during the 1980s with its all-wheel drive system. The car rapidly became the standard by which all other rally cars were measured. The competition was not standing still however, and in 1983 Audi decided to give the ever more popular pure racing cars a run for their money with a newly designed vehicle. The new Sport quattro, characterised by its shorter wheelbase, was launched at the IAA in Frankfurt in 1983. It participated in rallies for the first time the following year. The Swedish team with Stig Blomqvist and Björn Cederberg had a convincing win in the Ivory Coast Rally in 1984 with the powerful, 450 hp Sport quattro, earning for themselves the World Championship title and regaining the Manufacturers' World Championship title for Audi.
