2004 German Formula Three Championship

The 2004 ATS Formel 3 Cup was a multi-event motor racing championship for single-seat open wheel formula racing cars that took place across Europe. The championship featured drivers competing in two-litre Formula Three racing cars built by Dallara which conform to the technical regulations, or formula, for the championship. It was the second edition of the ATS F3 Cup. It commenced on 24 April at Hockenheim and ended on 9 October at Oschersleben after nine double-header rounds.

HS Technik Motorsport driver Bastian Kolmsee clinched both the championship and his rookie title. He achieved four wins, to overcome his closest rival Timo Lienemann by nine points, who won two races. Third place went to Jan Heylen, who started his season at Lausitz and won six races. His JB Motorsport teammate Michael Devaney won races at Oschersleben and Assen. Thomas Holzer, who completed the top five, lost 54 points to Devaney in the main standings. Other wins were shared between the opening round winner Jan Seyffarth and Jochen Nerpel.
