🔗 renntechmercedes.comThe story
Hartmut Feyhl founded RENNtech in 1989 after spending 12 years at AMG, including work on the development of the 300E 6.0 'Hammer' and a stint as AMG's Technical Director for North America. That insider knowledge positioned RENNtech as an unusually credible Mercedes performance specialist from its earliest days. The company is headquartered in Florida and is regarded as one of the reference points for AMG performance in the United States.
