Professional competence in demand

Particularly in the international Formula 3 scene, the technical competence of Spiess-Tuning has been extremely appreciated for many years, now. Hundredths of race wins and umpteen championships were won with engines that received the necessary power and were added the finishing touches to at Spiess-Motorenbau GmbH in Ditzingen.

One single example should be enough to highlight the success story: when Michael Schumacher secured the 1990 International German Formula 3 Championship title he also relied on the expertise of the Spiess engineers.

So, it comes as no surprise that the professional advice of Spiess and their explanations regarding the latest technical developments and the state of the art are regularly in demand. Recently, Holger Spiess was interviewed by a reporter team of the German sports channel DSF (Deutsches Sport Fernsehen).
