The Ferrari 126C3, introduced at the 1983 British Grand Prix at Silverstone, marked a significant step in Ferrari's Formula One campaign. Initially driven by Patrick Tambay, and then by René Arnoux from the German Grand Prix at Hockenheim, which Arnoux won, the car was an evolution of its predecessor, the 126C2B, retaining the oversized rear wing. Throughout the 1983 season, Tambay and Arnoux each delivered strong performances, collectively securing four wins. They both remained contenders for the world championship, but late-season reliability issues ultimately cost them the title. Despite these challenges, Ferrari succeeded in securing the constructors' title for the second consecutive year, underlining the effectiveness of the 126C3 in the competitive landscape of Formula One at that time.
