Speaking to What Car, Moers said "It’s probably something we should consider. We haven’t decided anything but in my own mind, as an engineer, I think it could be an interesting solution to have a high-powered four-cylinder petrol engine in a car that’s not a compact - maybe even a saloon." The executive went on to say the four-cylinder engine would make sense in markets where cars are taxed based on their engine displacement.
While nothing is official, speculation suggests certain AMG models could be offered with both a four-cylinder engine and a traditional V8. Interestingly, there have already been rumors about a C450 AMG Sport but that model is slated to use a twin-turbo 3.0-liter V6 with 372 PS (274 kW) instead of the turbocharged 2.0-liter four-cylinder engine that develops 360 HP (265 kW).
Besides talking about the four-cylinder engine, Moers downplayed the possibility of a diesel-powered AMG model but hinted "hybrid technology is something that we can start looking at."
