I think we all knew the four-cylinder AMG's were a step too far in terms of "downsizing". Either AMG ignored instinct, or they did it on purpose so that they could make an impact by "bringing the V8 back because we listen to our customers" type of deal. Same happened when Porche dropped the manual GT3, then made a killing when they brought it back.
