AMGRSM — Mercedes-AMG, Audi RS & BMW M Reviews and Comparisons

About AMGRSM: German Performance Cars Explained

AMGRSM.com is an independent automotive publication focused on the three most famous German performance divisions: Mercedes-AMG, Audi RS and BMW M. Our goal is simple: to help enthusiasts and buyers understand these cars in depth, from the engineering behind their engines to what they really cost to own.

On this site you will find detailed reviews of models such as the BMW M5, the Mercedes-AMG C63 and the Audi RS6 Avant, head-to-head comparisons like AMG vs Audi RS or BMW M5 CS vs Audi RS7, reliability guides that explain known problems generation by generation, and buying advice for both new and used performance cars. We also cover the history of the brands, legendary models and rivals from Porsche, Lamborghini, Cadillac and Tesla.

Every article is researched using official manufacturer specifications, published road tests, recall information and the experiences of owner communities. We update our guides as new models and information arrive, and we correct errors when readers report them.
