The top feeling when we can still get the decisive moment out of perfection.
The joy when heart palpitations get more revolutions. That’s RENNtech, since 1989.

RENNtech, Inc. was founded in the USA by Hartmut Feyhl. As a former technical
Director at AMG, he brought with him the experience and know-how to reinvent tuning.
Today, RENNtech has established itself worldwide as a professional in the performance tuning of luxury vehicles. “Performance Without Compromise” inspires Mercedes-Benz automobiles as well as Lamborghini, McLaren, Ferrari, Porsche, BMW, Audi or Bentley.

RENNtech EUROPE at the Nürburgring upgrades sports and premium automobiles with perfect tuning solutions. Thanks to our location on one of the toughest race tracks in the world, all the prerequisites for demanding product and vehicle tests are in place.
But we are also pioneers on the road, with more and more TÜV-tested products.

RENNtech develops and manufactures all products in-house, by the way in
constant exchange with our USA headquarters. Thus we guarantee
excellent quality at all times.

This is how we noticeably set luxury in motion.
With bundled forces, on all routes of the world.
