'Rejoice, fans of Mercedes-AMG's 4.0-liter twin-turbocharged V8, for it seems the engine will be returning to the hottest C-Class and E-Class models. Car and Driver reports that the V8 will be reinstituted as the halo engine for these models, as AMG fans aren't happy with the current engine range.

The all-new C63 is infamously powered by a turbocharged plug-in hybrid four-cylinder, while the next-generation Mercedes-AMG E63 is rumored to adopt a PHEV turbocharged inline-six. Apparently, these engines are not good enough to compete with what Audi and BMW have in store. The fate of the next-generation M3/M4 is unknown, but the current M5's successor will retain its V8 engine while adding a healthy dose of electric power. Audi's upcoming performance models will also be PHEVs, but they won't drop down to four cylinders.'

Interesting about-face, hope for more of that.
Guessing the 4-banger deal isn't attractive to the big spenders ?

Even to the small spenders.

I guess you can't sell what people won't buy. Funny how that works.

Thats no small feat for them to do either as the cars were never designed for them and will all have to re-crash tested and certified. Their buyers sent a clear message I'd say.

Your move, Dodge. (that arent much cheaper than C63 and E63's)

Had an Uber ride in an AMG of some flaor.

It rode like a Sherman tank

Not impressed, lol.

Probably one of the newer fake ones, they've been slapping the AMG badge on everything lately.

Turbocharged and intercooled small displacement gasoline engines have a small fuel economy advantage
over same horsepower non-turbo engines
in that their BSFC minimum is over a broader range of RPM.

But if the system has an added battery hybrid drive, that also can also “broaden” the best Brake Specific Fuel Consumption range of RPM.

If the richer customer expects a V8 in a premium car,
and the expensive turbo and intercooler cost can be eliminated,
the almost the same EPA MPG window sticker numbers could be gotten.

Does any customer buy an AMG model for better fuel economy?

The C63 went from a naturally aspirated 6.2L to a turbo 4.0L V8. It just went to a 4cyl hybrid - and now they're saying its going back to the TT 4.0L. It was the hybrid 4cyl that turned off the customers
