RENNtech is the leading Mercedes-Benz specialist and Hartmut Feyhl himself is regarded by many as the USA’s leading authority on Mercedes tuning.
He gained his 12 years of experience at AMG Germany before becoming Technical Director of the North American Division.
Prior to the merger of the tuning company with Mercedes-Benz in 1999, at the request of AMG Germany, Feyhl opened his own subsidiary to establish RENNtech and serve existing AMG North America customers.
This is the foundation on which we have built our reputation. RENNtech was founded in 1989 by Hartmut Feyhl and has evolved from serving AMG’s customers to a leading authority for tuning and customizing AMGs and Mercedes-Benz.
Over the years, we have developed high-performance products for almost all Mercedes-Benz AMG vehicles. Some of the most notable of these are the RENNtech E7.4RS at 322 km/h (honored by Car and Driver Magazine in 1996 as the “fastest sedan in the world”) and the newer 945 LB-FT 5.5L Biturbo RENNtech R3 + Monster. Each of these vehicles is just one example of what RENNtech has achieved.
With extreme performance, improved aesthetics and a fit that competes with factory cars.
