That’s the reason why I never had 6 cylinder S-Classes, TBH up to the 220 Mopf they were underpowered.You're once again making assumptions and putting words in my mouth.
Several business partners and acquaintances of mine own 6-cylinder S-Classes, and yes, at higher speeds and around town they have practically the same fuel consumption as the V8s. That’s an absolute fact, and it’s also logical: practically the same weight but less power – go back to school and learn some physics.
I don't know if you've heard, but there are different nuances of sound: the V8 in the 500 models (W140, W220, W221) is a beautiful blend of refinement and sportiness – not as "in your face" as the AMG models.
When I said "too raw," I wasn't just talking about the sound (which, in the current S63 W223, is honestly terrible, since the OPF completely muffles it), but about the entire configuration of the car – too aggressive design with too much plastic, an ugly grille with the central star, and a suspension that's too stiff for an S-Class.
You read superficially and then make silly and incorrect conclusions. Pay more attention to what I'm writing.
The 3.7L was the first okayish V6 S-Class, the 221 had the 3.5 4Valve which was even better.
The first acceptable 6 Cylinder was the S400 W222 with the M276 Bi-Turbo V6, this engine had finally some torque at low revs.
Biggest problem of the current S63 is the small trunk, fake sound inside and as you say the to stiff suspension.
I am absolutely annoyed that there’s no E-ABC suspension on the S680 Maybach, because this suspension needs 48V.
