Hi folks, what are your thoughts about a 2018 W222 - S560 Sedan Engine: 4L V-Shaped M278 under details shows V8 GASOLINE ENGINE M176, with 78,000 miles, it had regular services at an authorized MB dealer. Original MSRP was $160K, now for for $40K at an authorized Mercedes Benz dealer but AS IS.
I had a CLS550 with V8 biturbo engine and was great but not sure about the S560 with the new twin-turbocharged 4.0-liter V-8, 48V mild hybrid. Is that too many miles for a S560 engines. I heard S class could be very expensive for repairs when it reaches around 80k miles.
I still have a 2000, E320 with 270K miles that is bullet proof and runs so nice. I don't think they make cars like the good old models any longer.

Since your 2000 E320 was built MB has fallen many rungs down the ladder of reliability. MBs today are generally unreliable, especially so for engines and mild hybrid systems. Read this site for the gory details.

On the other hand, 78k is not particularly high mileage for a car that could be approaching 7 years since it was built.

Don't believe the W222 560 had the 48v system so you should be go there. That's a crazy amount of car for the money. Do you have the VIN? I'd be interested to see how it was spec'd to get a 560 up to $160k.

Its an M176 engine, the M278 was replaced with the M176 in 2018. No 48v mild hybrid either, its an ordinary 12v system. If its been well cared for I would not be concerned. The S580 in 2021 is the first year they became 48v

This is just not at all accurate when talking about this particular car. No mild hybrid system, and the W222 is actually very reliable. Look around the forum.

Correct, no 48v mild hybrid.

Have the dealer or an independent shop do a leak-down test on the engine (cost ~$300) to know the true state of the engine.

An authorized Mercedes Benz dealer is preparing this car before they put it for sale

If maintained well, there should be no problem at all .

GM, Ford, Mercedes, Audi, BMW, Dodge, Hyundai, Kia, Honda have made some very egregious engineering decisions that have set back the industry as a whole to please the environmentalists. However I don't think the 2018 S560 has 48v. If it did I would buy them just to dump them in the ocean. The newest Mercedes with 48v can remind you something is wrong pretty much on a daily basis.

I have an incredible emotional attachment to the W222 since they're such nicer cars and easily my favorite super sedan of the big 3. They're out of warranty now so I've been taking over service for them here in San Jose and they're wonderful cars. The 4.7 isn't without it's concerns either, nothing at this performance level is immune to criticism from any marque, but I've been very happy with mine in the W221.

The S560 does NOT have a 48v system, so we can stop guessing on that lol

2019 s560
1) no hybrid system
2) no 48volt battery
3) 4.0TT M176 motor. No concerns on this motor.
4) w222 is THEE LAST GREAT S CLASS

mine is at 68k miles and still brand new.
my last S class w220 was maintained well and ran like a clock.
same thing with this car, maintain and she runs forever.

So which year did Mercedes Benz S class added EQ Boost(48V) ?
I thought in the middle of 2017 they started using EQ Boost.
This car shows MFR Model Code S560V and M278 engine.

Once I test drove a 560, 4.0L V8 Biturbo and comparing to my S550 4.6L V8 Biturbo, didn't have enough power.

2021 eq boost. I have a 2018 with 65K miles, great cars, no real worries although like was said have a cylinder leak down test done just to be safe, don't take the dealers word for it. If you have cylinder wall scoring is new engine time which is about 40 grand. There was a guy on the forums recently that had that issue, believe he was over 100K miles but he dumped the car rather than fixed it.

chassis

W222 S550 used M278 cold vee used until 2017.

W222 S560 used M177 hot vee used from 2018. 48V starter/generator from 2018. This is not a 48V hybrid propulsion system.

W223 S580 used M177 hot vee plus 48V EQ boost mild hybrid from 2021. I wouldn't touch this with any length pole.

That news to me. The W222 V8 doesn't have a 48V starter. That would have been the i6 that didn't come to the US...

I would take all of these cars, including the mild hybrid... Also, only in the US are cars over 50k miles considered high mileage. Quite a few S560's in Germany at 200K kilometers right now; no issues. These V8's rock

MBNUT1

The S560 used the M176 not the M177.

chassis

OK M17x. The 4.0L hot vee engine.

chassis

Maybe need to submit a edit correction to the Wikipedia page. MB used 48V belt-driven ISGs before introducing the 48V transmission-mounted propulsion EQ BOOST motor.

SW20S

This is incorrect. The S560 has the M176 engine, the M177 engine variant is in the S63. There is no 48v starter/generator on the S560. That setup was used on the inline 6 variant that was not sold here. No US W222 has a 48v ISG

MBNUT1

I don't see anywhere where the S560 is associated with a 48V system.

Wolfman

There is a general statement in the article about the facelift but not related to any engine. I suppose chassis interpreted that as being on all engines for the facelift.

There is no need to an edit as this can be quickly validated with the engine article...

MBNUT1

Agreed.
