step1 – with Spiess as pillar

As innovative and development partner that is well established on the market, Spiess is involved as engine partner in an independently initiated, private project created and supported by numerous competent German medium-size companies.

Step-1 is the project name resulting from ‘Sportprototype Team Engineering Projekt 1’.

The vehicle is supposed to be called MiKar C 301 and to meet the FIA homologation regulations for Group E2 / SC and C3 sport prototypes respectively. Particularly the concentrated ideas of the involved companies – with the most different core competences – represent the most important components of this ‘different’ racing car. Certainly, not only project step1 but also the sport prototype resulting from it will cause a stir in road racing and the hill-climb sport, too.

Being responsible for the design, development, construction and production of the engine, Spiess represents a key player in this project. Also involved are less known partners such as ITK-Engineering or GFi but also renowned companies such as cp-autosport, Drexler-Engineering or KW-Gewindefahrwerke.

In late November, some 50 project members travelled to Spiess in Ditzingen for a meeting and – afterwards – a guided tour of the company-premises.

Construction 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.
Manufacturing 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.
Quality management 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.
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.
