Family American tuning studio RENNtech takes new heights with the introduction of the most powerful Mercedes-AMG GT 4-Door Coupe, designed for public roads.
The RENNtech atelier was founded in 1989 by Hartmut Feil, who previously worked at AMG and gained experience in forcing engines there – this is what RENNtech is famous for today, and it refines not only Mercedes, but also cars of other European brands, but Mercedes are still in the spotlight and the coolest RENNtech projects carry a three-pointed star. Last year, for example, specialists from Florida made the “world's most advanced” W140 generation Mercedes-Benz 600 SEL, and this week the RIIIx project based on the Mercedes-AMG GT 63 sports liftback is presented.

RENNtech achieves much more power without a hybrid add-on and raises the output of the M177 4.0-liter V8 biturbo engine to 1213 hp. and 1257 Nm (in stock it produces no more than 639 hp and 900 Nm) – however, such indicators are available only on fuel with an anti-knock index of 100 (read about what an anti-knock index is in our separate material), and if pour conventional fuel with an anti-knock index of 93 (in our opinion it is AI-98), then the return will be 977 hp. and 1147 Nm, which is also good.
