Simulation and success

2007/08
The fastest German single-seater series now is called ATS Formula 3 Cup. For many years already, wheel manufacturer ATS has been involved as partner in national and international Formula 3 racing. ATS is the only manufacturer worldwide to produce low-pressure casting aluminium Formula 3 wheels. The series will be called ATS Formula 3 Cup up to 2009 at least. The changed name, however, makes no impact on the resounding success of Spiess. The 2007 ATS Formula 3 Cup Champion, Carlo van Dam, also relies on the engine from Ditzingen, on the way to his success. The winning OPC-Challenge engine was designed by Spiess Tuning exclusively for the German market - as cost-saving and steady engine option.

In 2007, Volkswagen - an extremely successful Formula 3 competitor in the past - makes its comeback on the Formula 3 stage as engine supplier. First test races on the Formula 3 Euro series grid are held in September 2007 and the first win is celebrated as early as 2008 - in the third race of the season, held in Pau, Southern France. At the same time, the new Volkswagen engine also is used in the ATS Formula 3 Cup: by the reigning champions, the team of Frits van Amersfoort.

Engine manufacturing The engines are individual custom products and are assembled in the heart of the company by a highly qualified team. Here, quality instead of quantity represents the yardstick.
Test bench Here, the process represented by development and design, production and manufacturing comes full circle. On the test rigs, the components or the entire project have to definitively demonstrate if they meet the highest standards.
