Opening its doors in 1989, RENNtech quickly established itself as the nation's foremost authority on Mercedes-Benz performance.Building on the knowledge of Hartmut Feyhl (technical director of AMG North America and instrumental in the development of AMG's iconic Hammer) RENNtech developed a full range of performance parts and accessories for Mercedes automobiles - adding real value in terms of performance, finish, or luxury.The realization that high-performance tuning excellence didn't have to take away from the fit and finish of an automobile or deliver a harsh and noisy cabin led Feyhl to a radical sort of tuning philosophy:PERFORMANCE WITHOUT COMPROMISE.Following that mantra, the construction of each RENNtech vehicle is personally overseen by Feyhl himself; and each RENNtech automobile is assembled by hand, true to the ideals of Mercedes' performance cars: fast, yet refined - built to run flawlessly, idle smoothly, and deliver reliability and ease of maintenance comparable to a stock Mercedes-Benz.An obsession with quality, innovation, and solid performance claims have earned RENNtech the respect of the world's automotive press, and has made RENNtech the choice of the most discriminating enthusiasts in the world.
