Jan Fatthauer





9FF is internationally known for fast, street-legal sports cars. It will always be our aspiration to build world record vehicles. Still, power and performance only represent one side of 9FF.

On the other side, 9FF stands for aesthetic and individuality.  Accordingly, 9FF offers a complete programme for individualisation.  9FF designs sports cars to be even more personal and sporty, offering exclusive and sophisticated products.

9FF also stands for uncompromising quality - combined with the art of German engineering - and the guarantee of a vehicle manufacturer approved by the Federal Motor Transport Authority.


That's why driving a 9FF is something special.


Extraordinary performance can only be achieved with extraordinary people

Heading 9FF is "The Brain:” Jann Fatthauer. He perfected his engineering expertise in the field of vehicle technology to such an extent that he is today of the few, if not the only, "Engine Artists" in the world who can get far more than 1,000 HP out of a series engine.


His young team at 9FF consists of highly motivated engineers, talented car body builders, gifted master mechanics, diligent trainees and apprentices.

And they're all living the same dream: Make everything a little better.


Again and again, 9FF has set new records and captivated the world of car enthusiasts.

With a total of 8 world records in the last 10 years, 9FF has taken a global leading position in the refinement of sports cars. The fact that the vehicles can drive to the test track on their own four wheels is also part of 9FF's fundamental philosophy: They must be fully reliable, durable and, above all, roadworthy.
