Accelerate early,
brake late…   

… but never go off course

Our internal motto describes our competitive spirit: We are innovative, digital, and technically sophisticated – but never needlessly complicated. This enables us to reach our goal as quickly and safely as possible. Altogether, our explicit aim is to always skillfully combine all these maxims for the benefit of our customers.

From passenger and race cars to commercial vehicles and heavy trucks; from detailed analyses to complete modular solutions; from energy consumption optimization to environmentally-friendly measures and sustainability solutions – we have successfully implemented all this and much more over the past 20 years. And we are hungry for more.
