Audi's Hannu Mikkola beat the defending world champion Walter Röhrl and his Lancia teammate Markku Alén to the drivers' title.
German Walter Röhrl, champion of the previous year despite his manufacturer's failed bid to capture the title, was tapped to drive for the Martini Racing team along with Finn Markku Alén in the new Lancia Rally 037 car.
Audi Sport meanwhile carried forward from its successful title run in 1982 led by the same pair of drivers, Finn Hannu Mikkola and Frenchwoman Michèle Mouton, equipped with the Quattro A1 (later in the season upgrading to the A2 model).
Rothmans Opel Rally Team tapped former champion Finn Ari Vatanen and fellow countryman Henri Toivonen to drive the Ascona 400 during the season.
Mikkola teammate Blomqvist was impressive, finally winning in the last event of the year to place fourth overall, but Mouton's season was a disappointment, her fifth-place finish well off the pace.
