The E43 engine

RichardCranium3

So you're telling us the official AMG instagram page lied to us?

GreekUPS

Or is the official MB website false advertising that the turbos are bigger?

Why can't anyone just email someone at AMG...

^^^This. One way or another, someone at MB is wrong, as the info is contradictory.




The person replying on an instagram page is usually a low-level marketing person, who really has limited technical knowledge of the products. They are not going to be an engineer and they are going to reply with only the most basic of info. How many companies have a temporary intern manning a social media account? Read what they said: they both use the same system. Ask that instagram account to tell you the IHI model of the E43 and C43 turbos, and see if they can answer it. Then I might lean more towards believing them. I've seen plenty of "official" social media replies that ended up being wrong or inaccurate. I put more stock into the company webpage, which is going to include more vetted info, that is more carefully screened before it gets posted online. Then again, I've seen mistakes in that format too. The multiple auto magazines that have reported that the turbos are different tends to make me believe that to be the case, as usually they are talking directly to persons (designers, engineers, production managers, etc) that are associated to that car from the manufacturer. Whenever they are driving these cars for a press event, there is a manufacturer rep that is onsite, and available to provide more technically detailed info.

Is it really that hard to believe that MB might have dug into the parts bin from the E43 (especially since that model is now out of production), and decided to put that turbo onto the updated C43? Manufacturers often trickle down parts in model refreshes. After all, it's not like they had to have IHI spec a whole new turbo for the car, it was already a swap-able part. Not to mention that the cost-benefit balance, or the contract volume, may not have been reached with the E43 sales, so they decided to put it into the 2019s.

As I mentioned before, this is all speculative at this point, until someone can look at the compressor housing on a 2019 C43, and see what IHI stamped onto it. I am inclined, however, to believe that the larger E43 turbos are now on the 2019+ C43, and it would have cost MB almost nothing to do such an upgrade.

RichardCranium3

Not unreasonable to suspect MB and AMG-MB might get their info mixed up. It happens in all early production communications of different products all the time.

Whatever the case, since when did '18MY E43 and C43 have different engines/turbos? '18 models both share the same part number for the turbos on every MB parts page I've seen online (276-090-15-80). It's fine if both E and C are getting bigger turbos on the facelift models, but saying the C is adopting what the E already has is not supported by available info.

GuardianVA

Well, there are two separate part numbers for the E43 turbos, one overlaps the C43, the other doesn't. (2017 E43 left side turbo part #276-090-3-00 and right side turbo part #276-090-3-00, neither of which overlap into the C43). It does not appear that 276-090-15-80 is a superseding part number, so it's possible that there were different turbos on the E43 and C43 at one point in 2017, and then MB adopted the same turbo set for both cars in 2018. Only way to know for sure is, again, comparing the turbos themselves. It's a bit pointless to debate about it until then, either way.

I'd be curious to see, just because it would be interesting to know. If it's bigger, great. If not, oh well.

It works like this guys. The C43 came out, then the E43 with more power - larger turbos help with the large power output of the same engine that the C43/C450 has. Now, AMG is adding the E43 Engine to the C43 in order to push the C43 AMG to the level of an AMG while also changing the front to show it looks like it's v8 brother. All AMG cars will now get the newer AMG grills so that the new E53 has it's own look and newer inline 6 engine. It's easier for Mercedes to just put the E43 engine into the C43 to boost it's power instead that work has already been performed for the E43 by AMG.

"The E43 replaces the AMG Sport model from the previous-generation E-class lineup, and it fills the space between the base E300 and the hyper-performance AMG E63/E63 S. Its power comes from the same twin-turbo 3.0-liter V-6 that pumps up the smaller Mercedes-AMG C43, but AMG added larger turbochargers and updated software to boost horsepower from 362 to 396."

This sounds like the most plausible thing to me as well.
An interesting thing regarding this, I checked what racechip.com could do with the previous C43, and the E43 and the numbers were 434/643 and 458/604 in hp/nm, not much difference despites bigger turbos.
Guess there are other things limiting.

mbusa website just updated. 2019 c43 with 385hp, 384lb torque. 0-60 in 4.6 seconds.
looks like the new quad round tips is still fake. i like the current quad fake tips better, it' more unique and more aggressive . round tips, like every other cars brand, what' so special about it?

jonathan358

Thanks for the news although I have to disagree the quad tips are definitely more aggressive combined with the 63 diffuser.

@netboy Where did you see MB USA website updated? I logged on and dont see anything updated. Still shows the old C43 - 362HP and 4.6s

Hello All,

I run a MB store close to Pitt and I currently have a 2018 C43 AMG, bought it in FEB2018. I just looked up the turbo part # for 2018 MY and a 2019 MY in our internal system. Turbo part # on a 2018 C43 AMG is A-276-090-3280 and the list price for MY 2018 turbo is around $3,500 and it is available for purchase. 2019 C43 AMGs are at VPC for people waiting for them and their Turbo Part #'s are A-276-090-1900 for Left turbo and A-276-090-2000 for the Right one. These are not yet available for purchase from dealers, but part numbers are different as well as the price of $2,500 (MB prob doesn't know prices yet as the part hasn't been released yet so they just guess).

Hope this helps you guys out.

bdajeha

Could you compare the 2019 MY to the E43 then perhaps?

From AMG : "The Mercedes-AMG E 43 has HAD bigger turbos and more boost pressure. Now the Mercedes-AMG C 43 FL got the bigger ones of the Mercedes-AMG E 43 since the Mercedes-AMG E 43 was replaced by the Mercedes-AMG E 53 with another engine. "

jonathan358

I mean that does make sense... I doubt they implemented the E43 turbo only to scrap it, what, 2 years later?

luka43

2018 E43 turbo part #s are A-276-090-0300 for Left, and A-276-090-0400 for Right side. Looks like all of these turbos have the same housing and different compressor wheel designs on the inside, and of course different turbo pressures and engine tuning. I have looked at technical drawings, but have not actually put them side by side. As you can see all part numbers start with A-276-090 and only the last four are different.

Do you have some insider information from AMG or MB that indicates they are the same turbos for 2019? Have you personally seen the turbos firsthand to look at the IHI model # on the compressor housing?
Part #s don't always mean anything different, but if they aren't superseding, then it's just as likely that they are, in fact, a different turbo. From what I've seen, the different part #s are not superseding, so there is something different between the E43, pre-2019 C43, and 2019 C43 turbos.

As I have repeatedly said in this thread, until someone can actually see the turbos, in-hand, then there is no way to know 100% that they are different...but there is also no way at this point to say that they are not different either. MB has given out conflicting information on this, so it's hard to say one way or another right now.

FWIW, I got an official reply in the Private Lounge that 1.0 gen C43 and E43 had different turbos and tuning, and now that E43 has evolved to E53, 1.5 gen C43 gets the E43 setup. I also no longer care...

threefirs

Although I agree you might be right - this is just speculation. It's very possible they upgraded the internals of the turbo's..

GuardianVA

Yeah, that's what it is.....might as well lay yours on the edge of the table so we can see how you measure up.

Funny, didn't see anyone bragging about bigger anything, or even trying to make it about that. Just a thread started with a legit question about if the 2019 turbos were larger or different. Seems that more and more evidence is pointing to the turbos on the 2019 C43 actually being larger or having a larger compressor wheel. This has implications for tuning and overall power potential. God forbid that some people try to gain some insight or information, much less share it. We just can't have people asking reasonable questions or trying to find out information about the platform or what may/may not be different. Go ahead though, please add more valuable commentary and relevant information to the thread.

it was a joke. Don’t take things so seriously.

I am also curious about any differences in the engine from 2017/2018 and 2019.

guess I’m bi-turbo curious. Okay, I’m done. Thanks for reading.
