Audi

In 1977, the NSU days slowly came to their end. Spiess used the new, bigger facilities to focus on a new project: Audi. More precisely, on the 1.6-litre engine of the Audi 80 that was tuned for motor racing. New machinery, such as a camshaft grinder, proved to be of value within a short time and contributed to the optimum power output. The main focus was set on the cylinder head, the camshaft and the intake system. And again, reliability was another main focus of this project as the cars often had to cope with race distances of four or even six hours. The success of the Spiess engines quickly convinced Audi to also charge Spiess with building the racing engines of the works cars.

Design of completely new engines or the enhancement of existing power units –inventive spirit, courage, extensive team work and our huge wealth of represent the basis for innovative results.

Precision components or the refinement of existing components, single copy or small-batch series, solid material or cast material – a diversified service range thanks to an ambitious mix of know-how and new developments.

Out there on the racetrack, the smallest mistake can be crucial. Therefore, special emphasis is placed to a gapless and absolutely precise quality control. No part will be installed without having been subjected to an extremely strict examination.

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.

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.
