I'm looking into the C43 as a potential next vehicle and upon doing some research, I've read that the refreshed C-Class is due for new engines. Does anyone know if that affects the C43? From the articles I've been reading, it appears that both the 4-Cylinder and 6-Cylinder engines may change when the refreshed car is released in late 2018.

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."

Everything you read/hear on that is speculation. Nobody knows what MB will use, not even MB themselves. Of course I have no connection to MB except that I drive MB cars...

I wouldn't expect a new engine until the next generation of c-class.

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.

There is a chance they would change the engine. To all naysayers - it sounds as logical as this car evolving from the C400 to C450 to C43 in such a short period of time.

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'd be great for me because I'm thinking a used C43 will be my next car (don't care that it's "not a real AMG/no one man/one engine).

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.

Except the transition from c400 to c43 didn't have any engine changes other than tuning.

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.

Updates are normally cosmetic... I don't see big changes happening in the engine or trans department.

That's EXACTLY what I'm afraid of. The BMW 3-Series just went through this change with the F30's LCI refresh in 2016. The 335i changed to the 340i (N55 engine to B58) and the 328i changed to the 330i.


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.

that swap was from i6 to i6.

v6 to i6 isn't realistic IMO.

But, you can say you told me so if that isn't true.

5ilver-5urfer

I hope for my sake that you're right. I would hate to have an inline-6 available in my current car....might be tempted to swap for one....

2009 SL63 was a face lift with new drive train, both engine and transmission

Is the 2018 S550 going to be a FL model with a new engine? (560)

Mr. J

That new I6 engine will appear in the S class at least a full calendar year before it shows up in the higher trim C.

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.

The C-Class is due for a refresh for the 2019 model year. 4 years in the front (2015, 16, 17, 18) and three years for the refreshed model (2019, 20, 21). I believe that is the life cycle of the C-Class as the last gen was structured that way (2008,09,10,11 and 2012,13,14 LCI model). And if I recall correctly, the refreshed 2012 C350 got a new DI V6 engine, correct? And with a lot more power.

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.

I am very interested in what the 2019 C43 engine might be. I know we can wait year after year but... if an inline is coming im waiting.
