ATS D7

Early in the season, the D7 with its powerful turbocharged BMW engine, showed surprising speed, if not reliability. Winkelhock qualified sixth at Zolder for the Belgian Grand Prix and early in the race ran confidently in fourth place behind the Ferraris of Michele Alboreto and René Arnoux and the Renault of Derek Warwick before exhaust failure put him out on lap 39. He then qualified seventh for the next race in San Marino and again was racing in the points (top six) before his race ended in turbo failure.

Winkelhock only managed to finish two races in the quick but unreliable D7, finishing eighth in both Canada and Dallas. After joining the team for his first race in Austria, Berger enjoyed better reliability. He finished 12th at the Österreichring before gaining his first ever points finish in F1 by placing sixth in Italy at Monza. However, as ATS had only entered one car for the season and Berger was in a second entered car, no points were awarded for his drive.

Despite Berger's sixth place at Monza, the ATS D7 scored no points for the 1984 season. Following the season BMW stopped supplying the team with its engines due to the lack of results and bad publicity team owner Günter Schmid had gained for his pit lane antics. As a result, Schmid closed the team at the end of the season.

^‡ As Gerhard Berger was the team's second entry and as the team had only entered one car for the entire championship, the second entry was ineligible to score points.
