Mercedes-AMG GmbH, commonly known as AMG, engineers, manufactures and customizes Mercedes-Benz-branded vehicles. Mercedes-AMG is headquartered in Affalterbach, Baden-Württemberg, Germany. Originally an independent engineering firm specializing in performance improvements for Mercedes vehicles, Daimler-Benz AG took a controlling interest in 1990, then became sole owner of AMG in 2005. Mercedes-AMG GmbH is now a wholly owned subsidiary of Daimler AG.
AMG models typically have more aggressive looks, a higher level of performance, better handling, better stability and more extensive use of carbon fiber than their regular Mercedes counterparts. AMG models are typically the most expensive and highest-performance of each Mercedes class, with the exception of non-AMG V12 models found in the most expensive nameplates of the lineup.
AMG variants are usually badged with two numerals, as opposed to regular Mercedes-Benz vehicles which have three.
