That is fine and all but AMG currently makes a relatively tiny 2.0 liter four-cylinder motor. It is nice to see him support V8's, V12's, and larger displacement motors stating they are what AMG is about but he also spends plenty of time talking about the 2.0 liter four-cylinder in the 45 AMG's which has shown itself to be an excellent engine. He also knows Mercedes is cutting displacement as evidenced by the upcoming M177 V8.
Mercedes itself is already boosting output of their new twin turbo M276 DELA 3.0 liter V6 to 367 horsepower. Whether Moers admits it or not an AMG turbo V6 may be inevitable. That M276 engine can easily put out over 400 horsepower. The C63 obviously is getting a V8 this time around but when the W206 generation rolls around it would not be surprising to see a turbo V6 under the hood.
Regardless, in the lineup right now there is not a spot for an AMG V6 as the C63 AMG will use the M177 V8 and the CLA45/A45/GLA45 AMG cars are all fine with their four-cylinder M133 motor. It is nice to see that AMG will continue to support the V8 and V12 at least for as long as they can.
