Performance without compromise. This is the foundation upon which RENNtech has built their reputation. Established in 1989 by Hartmut Feyhl, RENNtech has evolved and grown from humble beginnings into the foremost authority on luxury
automobile performance tuning and offers complete tuning solutions for Mercedes Benz, Porsche, VW,
Audi and Bentley vehicles.
Over the years, RENNtech has developed high-performance products for virtually all Mercedes-Benz
AMG vehicles (including the commercial Mercedes Sprinter van and SMART vehicles). Some of the most
notable among these are the 200 mph RENNtech E7.4RS (which was called fastest sedan in the world
by Car and Driver in 1996) and the 2006 "Chrome SL" show car—an SL-based project entirely covered in
chrome. Each of these vehicles featured extreme performance, upgraded luxury features, and a fit and
finish that rivaled factory vehicles.
Historically, RENNtech has been a prominent Mercedes-Benz specialist, and Feyhl himself is regarded by
many as the USA's foremost authority on Mercedes tuning. His vast experience comes from his 12 years
spent at AMG well before the tuning company became part of Mercedes-Benz in 1999, then going onto
serve as that company's North American technical director prior to branching out on his own to start
Recently, RENNtech has begun to offer performance products for other marques specifically Porsche,
Volkswagen/Audi, BMW and Bentley vehicles. The product offerings focus on RENNtech's core competencies such as performance engine tuning, suspension, exhaust and custom fabrication.
