2014 MERCEDES-BENZ E-CLASS

Performance without compromise. This is the foundation upon which we have built our reputation. Established in 1989 by Hartmut Feyhl, RENNtech has evolved and grown from servicing AMG’s customers into the foremost authority on tuning and customizing AMGs and Mercedes-Benz. RENNtech also offers tuning solutions for Porsche, Audi, and Bentley vehicles, along with other European luxury cars.

Over the years, we have developed high-performance products for virtually all Mercedes-Benz AMG vehicles. Some of the most notable among these are the 200 mph RENNtech E7.4RS (which claimed ‘Fastest Sedan in the World’ honors by Car and Driver Magazine in 1996) and the more recent 945 LB-FT 5.5L V8 Biturbo RENNtech R3+ Monster. Each of these vehicles is just a sampling of what RENNtech has achieved, featuring extreme performance, upgraded aesthetics, and a fit and finish that rivals factory vehicle.

We design, engineer, and manufacture our proprietary line of tuning products in-house at our facility which features a full fabrication and machine shop with CNC and rapid prototyping capabilities; in-house performance dynos, complete engine management and software tuning capabilities along with a complete service/repair/installation facility and a full-time design, engineering, and sales staff.
