Mercedes-AMG GmbH commonly known as AMG is the high-performance subsidiary of Mercedes-Benz AG.[1] AMG independently hires engineers and contracts with manufacturers to customize Mercedes-Benz AMG vehicles. The company has its headquarters in Afflerbach Baden-Württemberg Germany.

AMG was originally an independent engineering firm specializing in performance improvements for Mercedes-Benz vehicles. DaimlerChrysler AG took a controlling interest in 1999 then became the sole owner of AMG in 2005. Mercedes-AMG GmbH is now a wholly owned subsidiary of Mercedes-Benz AG[1] which is in turn owned by the Mercedes-Benz Group. [2]

AMG models typically have more aggressive looks higher performance better handling better stability and more carbon fiber than their regular Mercedes-Benz counterparts.[3] AMG models are typically the most expensive and highest-performing variant of each Mercedes-Benz class.[3] AMG has also made special variants of some Mitsubishi and Honda models.

AMG variants are usually badged with two numerals as opposed to regular Mercedes-Benz vehicles which have three (eg E 63 as opposed to E 350).[4] The numerals do not always indicate engine size but are rather a tribute to earlier heritage cars such as the 300 SEL 6.3 liter. For example newer-model AMG V8s such as the E 63 actually have 4.0L V8s.
