Today RENNtech a prominent Mercedes-Benz specialist, and Feyhl himself is regarded by many as the foremost authority on Mercedes tuning in the United States.[6]
Following the 1998 merger of Daimler-Benz and Chrysler Corp. (which became DaimlerChrysler later), RENNtech expanded into the Chrysler category developing performance upgrades for the Chrysler Crossfire. In 2013, when Mercedes-AMG entered a strategic partnership to produce V8 engines for Aston Martin, RENNtech followed suit by creating performance upgrades for the M177 powered Aston Martin Vehicles.
RENNtech has expanded their product line to include other car manufacturers - specifically Porsche, Aston Martin, Bentley, Rolls Royce, Maserati, Volkswagen, and Audi vehicles. These product offerings focus on RENNtech core competencies: engine tuning, braking, exhaust, transmission, and suspension.
RENNtech's primary focus is to achieve maximum car performance through the increase of horsepower and handling. Customers can either buy the upgrade parts from RENNtech, or send in their cars to be customized at their headquarters in Stuart, FL.
RENNtech also offers cosmetic modifications including aerodynamic body kits, carbon fiber splitters, and multi-piece forged alloy wheels.
