2019 C43 AMG Refresh/LCI Will Have An All-New Engine?
I know that the when the C-Class was released for the 2015MY, the V6 was the C400, then it changed to the C450 in 2016 (with some drastic vehicle changes after just one model year), and now the C43 AMG just a year later. So it seems Mercedes is not shy about making significant changes after just one year. So should we expect a new C43 AMG engine for the LCI?

"As mentioned earlier, the 6-cylinder engines adopt an inline-6 configuration, with a 3.0-liter displacement... Mercedes says the ISG can add a 20 horsepower and 162 pound-feet of torque boost during high-load situations. The automaker boasts that the overall result is a 6-cylinder that offers the performance of an 8-cylinder. No numbers have been confirmed but Mercedes says to expect over 408 hp and 368 lb-ft."

Even if they managed to shoehorn an i6 into the current gen, too much weight will be past the front axle resulting in poor driving dynamics that they would likely try to make up for with adding trick rear differentials.

Are you not in the market for a C43 for the next ~20 months? If that's the case, then it might not hurt waiting...but then again, you may be only 24 months out from a full model update at that point...

That said, the W204 FL was relatively substantial and the engine was essentially untouched, so I wouldn't be surprised if there were just some small tweaks... a C43S would be cool but I'm doubtful.

I don't see your point. They are all very much the same car and I can't pinpoint a single facelift that included an entire drivetrain swap other than the new 991.2 which switch from NA flat 6 to turbo charged.

No one said that the transition from C400 to C43 was an engine change - the point was that an automotive manufacturer can and will change anything they want, regardless of what a regular consumer anticipates.
Manufacturers change engines mid-cycle all the time - whether they coincide with a body update, that's up to the manufacturer. See N55 to B58. As for Mercedes going from a V6 to and I6...I don't anticipate it will be all that hard for the boys down in Germany.

Motorauthority is a pretty reputable auto site and the changes seem entirely plausible for an LCI. And as mentioned above, their primary competitor (BMW) did the same thing for their mid-year cycle refreshes for the 3-Series.

MB has invested quite a bit into the current generation of TT V6s. I seriously doubt they are going to walk away from these engines while they are still edging out BMW and Audi as far as engine specs go. The '43 lines will be given a little more time to mature. Audi will likely have an upgraded powerplant in its S line models in 2018. Mercedes will probably upgrades the 43's with the I6 for the 2019 or 2020 model year.

With that in mind, I would put money on the new engines being implemented in the 2019 model year (LCI year), which should be available sometime in late 2018. That only seems logical based on past history.
