The ATS D7, a Formula One racing vehicle fielded by Team ATS during the 1984 season, was engineered by Gustav Brunner. Primarily piloted by German driver Manfred Winkelhock, the team later added Austrian rookie Gerhard Berger to a second car near the season’s end. This model marked the final iteration produced by ATS. Equipped with a robust turbocharged BMW engine, the D7 demonstrated notable speed early in the season, though reliability issues persisted. At the Belgian Grand Prix in Zolder, Winkelhock secured sixth in qualifying and briefly held fourth place during the race, trailing the Ferraris of Michele Alboreto and René Arnoux, as well as Derek Warwick’s Renault, before an exhaust failure forced his retirement on lap 39. He followed this with a seventh-place qualifying effort at the San Marino Grand Prix, where he again competed within the points (top six) until a turbo failure ended his race prematurely. Despite flashes of competitive performance, the D7’s technical challenges underscored its inconsistent campaign.
