Call me crazy if I got to decide the engine for the G8X, the electrified AMG-tuned 4 cylinder would be my pick over the S58, given no other options.

Pity for you then

I'd skip both and get a rs6 avant.

The new 4series will have 48v mild hybrid. I would not be surprised if the New M3/M4 came with that upgrade to the S58 engine and smooths out and instantly puts the power down power

This would be an awesome powertrain in the AMG C-Class, and a much better replacement for the highly coveted V8, rather than dropping half of its cylinders. Not sure they couldn't reserve the 4-pot for the lower-tier AMG 35/43 model and at least save a "larger" displacement engine for the top-tier AMG 53/63 model.

I bet they use the inline 6 for the C63 and maybe 4 for lesser models?

If that's the case, skip the RS6 Avant and just jump straight into an E63 S AMG Wagon for that AMG V8.

To my understanding, the purpose of 48-volt electrical systems is not to enhance hp of the drive system as a ("mild") hybrid as you say, but rather for additional power to run the car's ever more hungry electrical system (e.g., infotainment system, electronics and electric motors running more and more things).

Most cars run on a 12-volt system as cars use DC 12-volt batteries. But now automakers are either switching over to 48-volt systems, using 48-volt lithium-ion batteries, or adding them on top of the existing 12-volt system.

[SeanWRT]

Correct.

48V at current stage is there only for efficiency. In low hp application, it provides a bit "torque fill" but it's by far incapable of filling the torque deficit for 500hp S58 off boost.

Why not going for electrical supercharger route like amg 3.0? Because of the complexity and packaging. too much stuff up front and reliability risk, and too little to get in return.

The only true lag eliminate solution with 48V to such high hp application, is the electric compressor and elimination of exhaust turbine. With such tech, every bit of power is pure internal combustion. But it's clearly a future technology not even sure will come to market given everyone is more interest to push plug in hybrid and full electric techs.

It's a mild hybrid meant to mitigate lag

Were any sources mentioned in this vid? It's difficult to believe the scenario where a v8 gets downsized directly to the 4-cylinder when they clearly have more left in the straight 6.

I didn't watch the whole video but I've been hearing this 4-cylinder C63 rumor for at least a few months now, maybe even a year.

He did mention in the video that Tobia Moers was pissed about the decision to move away from the V8 to a 4-cylinder hybrid.

[nublu2u]

Does seem strange going from the v8 to a i4 hybrid, especially with a fairly new i6 mild hybrid available (m256). Perhaps this engine is destined for the future E63 (not the imminent facelift) as the whole range downsizes.

[Clemenza]

The head of Aston Martin chimed in on a interview with Autocar UK, basically saying they see/know where AMG is going with their engines (V4/hybrid), thus Aston developing their own V6/hybrid. You will not see in AMG sourced V4 in an Aston he stated

[V-Eight]

I'm not surprised. It's at least six month that we hear about the 4pot here in Europe.

Now it's real. Ok, RIP AMG. I've never bought one, but I have to admit that their v8s were legendary, especially from 2000 to 2013.

The only selling point of the C63 was its engine, now will have a lot of power, but will offer nothing that can be defined as "exotic".

Before buying my current car, the F20 M140i, I drove really well both the RS3 (really nice car and sound but too much artificial), and the "old" A45 AMG, which was very balanced, but completely no engaging and with an awful sound. That engine produces only farts while changing, and is nothing more than a common Renault Clio SPort or MINI JCW, why have I to spend more than 60k euros for a jumped UP common car? My M140i is copetely stock (apart the rear differential) but is surely more special and technically advanced due to its engine and drive. is it slow? No worries, with less than a 1000k euros it can become a real killer, with just a simple engine map a different brake pads. No matter so, If I want I could tranform it in a real racer, but with a 4 pot which will be the difference? A drag race? Ok, it's only a win for a common softened driver...who buys products like the A45 it's not a real enthusiast, and it's not a real petrolhead, in my opinion. In terms of car, is what you buy and drive that defines you. The only 4 pot that I accept for an enthusiast is something coming from the past in classics Porsches, Alpines, Alfa Romeos or Lancias.

Ok guys, I'll go over the bad grille, BMW made another goal. It'll be the only real Sport sedan beside the AR Giulia Quadrifoglio facelift. There's no choice, but.....let's say thanks to God.....at least for other six/seven years we could buy a real sport sedan....not a sporty version of a forklift.

[535i MSport]

It will be a real shame if this goes. As others have said, one very good reason to go the Mercedes-AMG route.

[duky]

Did anyone else just get an email survey from BMW asking if they would buy a 4-cylinder M3 if the 6-cylinder were no longer available? Interesting that they are definitely thinking of going this route too

Or...

The M139 engine in the Mercedes-AMG A45 S already puts out 416hp, so the (non-hybrid) C43 will use a derivative of this and then the C63 will use same 4-cyl M139 but adding hybrid technology to kick it up to the (for the C63) 500+hp targeted area.

I think your guess is most likely what MB will do.

[evanescent03]

maybe MB can make a more exciting 4cyl than Porsche's powerful, well mannered, but boring boxer motor. I'm just not sure a 4cyl can be exciting... ever. The C63 is meant to be a mix between businessman/woman and barroom brawler. Almost makes me want to scoop up a current MY C63 for that beautiful V8.

I had a 2018 RS3. While it was fast, from a stand still it's very boring. Without launch control which I don't think people would be using for every acceleration, when you floor it nothing happens for a couple of seconds then it starts to really move. Very boring.

I wanted to love the RS3 so much but honestly for 99% of my daily driving the S3 felt punchier in and around town. Backroad, no traffic situations are really fun in the RS3 and that's where it shines. Still love the looks of them though!

[The Automotive Enthusiast]

I read an article not too long ago that the next generation will still hold on to the V8. Conflicting reports. :/

[MmmmmM2]

Not sure how this one is going to go over, so...
