When it comes to high-performance vehicles, Mercedes-AMG and BMW M are class rivals. As BMW makes M models of its best Series vehicles, so too does AMG soup up its standard lineup with AMG versions. Choosing which one is at the top of the segment will be largely subjective as each has its strengths and weaknesses: traditionally, Mercedes-AMG provides more lavish interiors coupled with raw power, and BMW M produces cars with superior handling and driver engagement, but both are leaders in the field.
