Mercedes-AMG is the high-performance subsidiary of Mercedes-Benz AG. AMG independently hires engineers and contracts with manufacturers to customize Mercedes-Benz AMG vehicles. The company has its headquarters in Affalterbach, Baden-Württemberg, Germany. AMG was originally an independent engineering firm specializing in performance improvements for Mercedes-Benz vehicles. DaimlerChrysler AG took over AMG in 1999, and it has been operating under Daimler AG since then. The AMG designation on certain Mercedes-Benz vehicles stands for "Aufrecht Melcher Großaspach," the last names of Mercedes founders, Hans-Werner Aufrecht and Erhard Melcher, and the name of a city in Germany where Aufrecht was born. AMG vehicles are designed to have more power and finer handling, and have a unique sporty look due to their exterior and interior embellishments. Perhaps the most important feature that distinguishes a Mercedes-Benz AMG vehicle is its engine. Each one is handmade in an exclusive manufacturing facility in Affalterbach, Germany.
