ATS D4 like many 1980 cars looked very much like a  Williams FW07. The car designed by Gustav Brunner and Tim Wardrub was lighter, shorter and narrower than the ATS D3. ATS team started 1980 with a pair of cars, which they described as being D4s. The first of these was a modified version of the D3 introduced the previous autumn, and the second was its brand new twin. These were used in South America and most publications called them D3s, but it appears that the team was calling them D4s. However, ATS then introduced a new model at the South African GP which was also called the D4. So the two cars used in South America must be regarded as updated D3s, and the South African GP car as the first D4. The team started the season with drivers Marc Surer and Jan Lammers, but since 4th round of the season in Long Beach only one car was entered – first for Lammers, and then for Surer. Surer finished in 7th position in Brazilian Grand Prix in a modified D3 chassis, and this was the best ATS result of the year. For the German GP of 1980 a second ATS D4 was prepared for Austrian Harald Ertl. Racing successfully in touring cars and being German Champion in a BMW in 1978, Ertl was less lucky in his parallel Formula 1 career. Disappointing results with Ensign in 1978 made him pause in F1 in 1979 and race a Ford Capri Turbo in the DRM. 1980 German Grand Prix was his last appearance in Formula 1, but while teammate Marc Surer qualified 13th the spare car for Harald Ertl failed to qualify.
