Question: are all amg engines hand built?
Answer: All AMG engines - with the exception of the "43" M276 3.0 L V6 Bi-Turbo engine - are hand built using a "one man, one engine" philosophy at the current AMG plant in Affalterbach, Germany. To signify this, each AMG engine builder stamps the engines they produce with an engraved plaque depicting their signature.
