Anyone else think the facelift sounds different? To me it has more of a vroom sound whereas pre-facelift it sounds more like a muffled bark.

 

I think the sound was from a different car.

 

it might just be a bad (sound) recording.

I love the interior!!!!!!!!!!!!!!!

 

That dash... new screen... new taillights... and are those vented sport seats? FML, almost regretting that I picked up a 2017 recently.

 

 

I thought advertising literature suggested a few tweaks to the facelifted exhaust?

 

 

 

The face-lift has the exact same engine and exhaust... I think there will be another software update coming up soon.

 

It does sound very defined in that recording and does not sound muffled at all, but I think that is due to being in an indoor environment. It's really hard to get a good recording of any car because you would have to get microphones that are dedicated for really good capture of lower and higher frequencies.

 

 

Not sure if it's the case here, but I remember reading that these media test cars often have tweaked exhausts that are slightly louder than the production cars.

 

Rumor has it that the 2019's will now have a particulate filter in the exhaust, so MB decided to pipe engine sound in the cabin (like BMW) to compensate.

That's why "Remove before Race" said it now sounds more like an E63.

Guess we'll see.

 

 

yea i dont believe so

 

From https://www.whichcar.com.au/reviews/...-sedan-review:

"Mercedes-AMG has cheekily added a synthesised induction note to the C63 as part of this update, but far from sounding obviously fake, it improves the overall noise with an exhilarating upper-rpm snarl complimenting the fat, bassy V8 tailpipe bellow."

 

 

 

 

2018 or 2019, here's my theory:

The 4.0 Bi-Turbo V8 will keep being built, no problem. It's the best engine AMG has ever built - and they know it.

However, you will have to pay a lot more for any V8 AMG in the near future. It will only appear in much higher priced AMG cars. Just look at the new S63 which now has this engine, replacing the much larger displacement predecessor.

I was looking forward to later selling my 2018 C63S and eventually buying an AMG E63S Coupe. Result - not happening and, instead enter the E53 Coupe. Really?
Sorry, there's no comparison, no matter how cool the new E53 Coupe looks inside and out, or how you slice it.

Beginning with the 2020 or 2021 model year, I predict that you will will no longer be able to get a C class AMG with a V8. That future AMG C Class going to be powerful no doubt, but some sort of chipped inline 6 with Hybrid, or something to that effect, will be in the car.

That means say good bye forever to an AMG V-8 under $90,000.00.

So..... All of you pondering 2018 or 2019, pause and think about it. Either year you choose, you may have the last C63 or C63S ever made.

Your thoughts?

 

They certainly do seem to sound the same in that vid, however from a lot of journo reviewers comments the 19's sound better from within the cabin weather that's synthesized or not who knows, again from comments the 19's sound quieter from inside the cabin when cruising that's going to be a big plus for some people.

Agree with most of the above, pricing aside as it varies greatly around the World this will be the last and the best V8 RWD C Class AMG ever built definitely worth buying and keeping

 

I cross posted this to the AMG PL but thought I'd post here too:

I'm considering a 2019 C63S coupe and this does concern me about the GPF particulate filter affecting the sound (and power). According to the initial youtube reviews the sound is definitely different. Perhaps more of an E63 sound in the cabin (not necessarily a bad thing), but will it have the deep gutteral rumble/noise on the outside?

This is the sound of the new 2019 facelift C63S coupe (skip to 11:55):
Take this video of the pre-facelift (2017) C63S coupe as a comparison:
It's a bit difficult to tell from videos, but I really really hope the sound hasn't been diluted compared to that!

 

Yes, that is a concern.

That's why they piped intake sound in the cabin for 2019, since they can't do anything about the filter for the exhaust (unless, of course, it's only in cars delivered outside the U.S.). Do you know?

If the piped in sound isn't too fake (like BMW and Mustang), then I would welcome it.

However, I really like the low RPM deep exhaust rumble in my 2018 when cruising around town in "comfort" mode with valves open, and I'm not sure anything could be done about that for 2019.

Only way to really know is to test drive both yourself, which will mean waiting.

 

I was curious, so I found the below article. At the end, it suggests the filters won't be needed in North America. Question is - will MB still just put them on all 2019's since they are built in Germany?

*********************************Gasoline Particulate Filters

W. Addy Majewski

Gasoline particulate filters (GPF) are an emission after treatment technology based on diesel particulate filters (DPF), developed to control particulate emissions from gasoline direct injection (GDI) engines. In some German literature, the technology is also referred to as Otto particle filter (Ottopartikelfilter in German), abbreviated OPF.

The population of GDI vehicles has been increasing, driven by CO2 and/or fuel economy requirements. In 2016, an estimated 2/3 of new gasoline cars in Europe were GDI [[url=javascript:oRef(3615);]JM 2017]. The proportion of GDI vehicles has been also rapidly increasing in North America—within nine years after its first significant use in the market, GDI penetration has climbed to 48.5% of new light vehicle sales in the United States [[url=javascript:oRef(3616);]Davis 2017]. Emissions from the growing GDI vehicle fleet are a public health concern and a potential major source of ambient particle pollution in highly populated urban areas.

GPFs are expected to be used primarily in the European Union and in China, to meet the particle number (PN) emission standards for GDI vehicles—passenger cars and light commercial vehicles—adopted in both jurisdictions. The Euro 6 and China 6 regulations set PN (as well as PM) limits for GDI vehicles that are equivalent to those for diesels. The European PN standards, both effective for new types of GDI cars from September 2017, are:

• A PN limit of 6.0×1011 km-1 over the NEDC / WLTC test cycle (Euro 6c)
• RDE testing for PN emissions with a conformity factor of 1.5, i.e., PNRDE = 9.0×1011 km-1 (Euro 6d-TEMP)

The above standards could also be met—at least in certain types of vehicles—via in-cylinder controls such as fuel injection strategies, without particulate filters. However, the GPF has several advantages compared to in-cylinder controls:

• Effectiveness under all operating conditions—While in-cylinder strategies tend to be more effective under certain modes of operation, the GPF provides PN emission control under all engine operating conditions—an advantage that is especially important in RDE testing.
• Control of emissions from engine faults—Increased PN emissions can occur as a result of engine faults and malfunction, such as increased lube oil consumption. These emissions can be effectively controlled by particulate filters [[url=javascript:oRef(3632);]Czerwiński 2017].
• Control of unregulated emissions—The GPF can control certain unregulated emissions, including polynuclear aromatic hydrocarbons (PAH). GDI engines, even though equipped with three-way catalysts (TWC), may produce significant levels of toxic PAH emissions [[url=javascript:oRef(3618);]Muñoz 2017].

Gasoline particulate filters are not expected to be widely adopted in North America, where particle emissions are regulated through mass-based PM limits only. The US Tier 3 PM limit of 3 mg/mi, as well as the 2025 California LEV IIIlimit of 1 mg/mi will likely be met through in-cylinder control technologies.

 

Do you think it will be possible to remove the GPF filter to get the "old" sound back? A bit like de-catting. Guess time will tell.
​​​​​​I very much want to get a W205 C63S before they lose the V8 in the next generation. As soon as AMG lose the sound the brand is dead to me (look at the new E53 AMG coupe, sounds like a puny vacuum cleaner!)
