Renntech Inc. is an American high-performance automotive aftermarket tuning company founded in 1989, with their headquarters located in Stuart, Florida. RENNtech specializes in engineering, designing and manufacturing parts for Mercedes-Benz, AMG, Maybach and Mercedes-Benz Sprinter vehicles as well as other European luxury and performance vehicles. RENNtech also operates a full motorsport division named RENNtech Motorsports fielding a Mercedes-AMG GT4 racecar in SRO's North American GT -series. RENNtech Classics was founded to offer a wider range of services for owners of early RENNtech, Pre-Merger AMG, and collectible Mercedes-Benz vehicles.
RENNtech was founded by Hartmut Feyhl in 1989 as a result of the AMG Mercedes-Benz merger. Prior to the merger, Feyhl spent 12 years at AMG, first as a past of the team developing the Mercedes-Benz 300E 6.0 AMG "Hammer" and later serving as that company's Technical Director at AMG North America in Westmont, Illinois.
Feyhl named the company RENNtech, combining the German word for racing renn and technology, and continued to service AMG's North American customer base from Florida while maintaining a connection to AMG's headquarters, and Hans-Werner Aufrecht and Erhard Melcher.
RENNtech has designed and developed high-performance products for virtually all Mercedes-Benz AMG vehicles since 1989 (including the commercial Mercedes-Benz Sprinter van). The company received considerable press with the RENNtech E7.4RS, and the 2006 "Chrome SL" show car, an SL-based project entirely covered in chrome paint. RENNtech cars are often featured on social media, blogs, and on the covers of major automotive magazines including Car and Driver,[1] eMercedesBenz,[2] Motor Trend,[3] AutoWeek,[4] and Modified Luxury & Exotics.[5]
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. Other upgrades include racing LSDs, open racing exhaust systems, performance disc brakes, and engine remapping. Customers can also have complete engine overhauls, and upgrades to larger displacement.
RENNtech engines range from small 200 horsepower (150 kW) K4 blocks for SLK roadsters and CLK-Class to the 1198 horsepower (670 kW) twin-turbo M177 -engine for the AMG GT63 4-Door Coupe.
RENNtech Classics offers complete engine overhauls, restorations and performance upgrades for classic Mercedes-Benz and AMG vehicles. These services include increasing the engine displacement through bore-and-stroke, exhaust systems, suspension and improvements to the interior from custom upholstery, gauges, shift knobs, pedals, and trim to various electronics.
