Mike sent me a link to an article about AMG... hell, I didn't realize I had no idea what the hell the acronym AMG represents

AMG evolved from the pet project of two intrepid M-B engineers whose passion, desire, and devotion far outstripped their means. 

Hans Werner Aufrecht and Erhard Melcher were engineers developing the racing engine for the Mercedes-Benz 300 SE in the early 1960s. 

Unfortunately for them, Daimler-Benz decided to cease motorsports involvement. Disappointed but undeterred, the pair continued work on the engine on the sly at Aufrecht's house in Großaspach

To further its development and prove their skills in a competitive arena, the pair planted the engine in the bay of an MB 300 SE in the German Touring Car Championship, and went on to win—10 times.

The pair's expertise with Mercedes-Benz performance now firmly cemented, Aufrecht realized the time to strike was now or never. 

He and Melcher found a company called Aufrecht Melcher Großaspach engineering firm, focusing on designing, testing, and developing racing engines. 

The AMG acronym naturally followed; its phonetic ring makes it both authoritative-sounding and easy to memorize.
