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.

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.

RENNtech is an authorized Akrapovic exhaust dealer and also the exclusive North & South American distributor for Aixro rotary race engines. Our Aixro race engines also power the world’s fastest and exclusive racing karts, the RENNtech SLR kart, which is built in house by RENNtech.

RENNtech designs, engineers and manufacturers their proprietary line of tuning products in-house at our facility which features a full fabrication and machine shop with CNC and rapid prototype capabilities; an in house performance dyno, complete engine management and software tuning capabilities; a complete service/repair/installation facility and a full time design, engineering and sales staff.
