2025 CLE63AMG
Breaking down the 63's by class, it's only logical the CLE63 will remain a V6 with an added electric motor sporting the E Performance badge:
C63 V4 + E Performance
CLE63 V? + ???
E63 V6 + E Performance (planned)
S63 V8 + E Performance
SL63 V8 + E Performance
GT63 V8 + E Performance
*Sorry for flaming out the V8 hopes.

It's absolutely adored in the CLA45, and even has been rated higher/better than the 5 cylinder Audi in that segment, which has a heap of character and sound.
The transmissions issues lately seem to have been more highly criticized portion of the drivetrain than the 4 cylinder itself. That mixed with some manufacturing issues has really given the 4 cylinder a hard time to stand on it's own in the new chassis.
Even though the "numbers" are so much better looking for the M139L + P3 PHEV combination, it'll still look like a down grade to the 2 already released CLE 450 & 53 variants with inline 6 engines + mild hybrid...

The M139L is a wonder of an engine no doubt and a further development of the current M139 in A Class AMG's.
I never thought I'd see the day where an OEM would build a mass production vehicle engine to those specifications, so kudos on them for that effort.

MB knows how to do both 8 and four cylinders right, we won't deny that.
It is just this complicated E Performance system that they haven't quite perfected yet. It also seems rushed but I guess they don't have a choice because they need a C 63 for the W206 (to compete in the segment instead of spending many years further developing the car and not releasing it) and they already abandoned plans for a V8 in the W206 a long time ago.
However there were praises of the drivetrain working well with the V8 in the S 63 E Performance so they are working their way there or perhaps the powertrain is better mated with the V8?

Last line caught my attention as I'm also curious as to why from all the reviews the same/similar V8 + P3 driveline in the new S63S E is so much better than that in the GT63S E 4dr...
Maybe because it's programmed towards luxury and not sporty, therefore the synergy between the 2 different powerplants does not mess up as much and also being a luxury transporter weight is not of concern ?
But leading on from there I'm really curious to see the outcome of the new GT63S E coupe and am hoping it too turns out good like the new S63S E and better than the GT63S E 4dr, it would make for a compelling DD for any 2dr coupe aficionado.

I'm sure they've ironed out a few things with the latest software and all. They did have quite a bit of time to do that since the GT 63 SE came out as their first attempt. However, as said, the S 63 is not exactly a car that somebody takes on a track. It weighs 5500 lbs and is essentially a straight line Autobahn rocket/barge. Going fast in a straight line with that much weight isn't particularly difficult. Just a matter of power. Wrestling it around a corner is a different story, but the S63 was never exactly a canyon carver, either. Reviewers also seem to like the new GLC 63 S E better than the C63, even though it has the same powertrain, but it also seems to suit an SUV that is already heavier better than a performance sedan and coupe. I suppose if the CLE 63 will really get the 4 cylinder it'll be interesting to see what people think and if AMG has at least ironed out some of the issues. The weight issue will still be there, though, but I'm curious if they managed to get rid of the lag. From what I understand, the C63 production has been put on ice for the moment, supposedly to iron out the issues that have been plaguing it, so will see how this evolves.
Just watched RBR's latest vid and review on the GT63S E and it was a very different story and outcome compared to when he reviewed it shortly after release.
He also mentioned a valid point that the GT 4dr being an older model was not designed with the P3 hybrid set up in mind, whereas all these newer models are so it looks like as they mature over time they could end up being rather good.
Porsche seems to have nailed it with their new Cayenne S E hybrid with V6 engine, but then Porsche is Porsche so a pinnacle result is not at all surprising

This newest mule is wearing the same overly fussy and ugly wheel rims that are standard on the CLE53, whereas previous mules under wraps were wearing the much nicer design as used on the new GT coupe.
I suppose we'll know everything in the next few months.

If they were going to use the powertrains of the new E Class AMG's there would be a charging port there.
My guess is that MB do not want a repeat of the uptake failure of the W206 C63SE and this vehicle is a "powered up" M256 that's in the CLE 53 and that will also be used in the upcoming E63 along with the P3 hybrid plug in pack.
It also explains why the release of this variant has taken so long since first seen years ago now, they obviously re-engineered it with a different powertrain.

There would have been no chance of this until not too long ago and makes total sense since the 2 variants below it are 6's.
It also puts some positivity back into the new upcoming E63 to also feature a V8 as that's the only real way to effectively compete with the new upcoming M5.
