The info came straight from Tobias Moers, the current head of Mercedes-AMG, and it would normal end all other speculation. Fortunately or unfortunately, it doesn't.
As some of the three-pointed star aficionados out there are already aware of, Mercedes-Benz is currently working on an entirely new family of inline three, four and six cylinder engines. All of which will have gasoline, diesel and hybrid versions and will also share quite a number of components between them in a truly modular fashion.
While most of those twin-turbocharged modular inline sixes are reserved for the C-Class (W205) facelift and the upcoming W213 generation of the E-Class, one of them might also find its way under the long hood of the AMG GT (C190).
This is naturally yet another speculation on our part, but it does make sense if Mercedes-Benz wants to transform the AMG GT in a true Porsche 911-fighter as far as the engine range is concerned.
On top of that, V8 purists shouldn't feel offended by a Mercedes-Benz sports car with an inline six, as the most loved three-pointed supercar in history also had such a configuration under the hood (300 SL, obviously).
Recent reports say that the most powerful version of the new inline six engines should output at least 435 hp and a massive 750 Nm (553 lb ft) of torque in the E-Class (W213), numbers which wouldn't fare too bad in a base AMG GT (C190) either. Would you like such a model?
