The walk-back nobody wanted to admit was happening
When the W206 C63 traded its 6.2-litre V8 for a 2.0-litre four-cylinder PHEV, Affalterbach told us it was about the future — F1-derived tech, electrified torque, 671 hp from a half-litre per cylinder. The numbers were there. The character was not. Two years on, the message has changed.
Multiple sources inside the Mercedes-AMG dealer network indicate a CLE 63 4MATIC+ is in late development for a late-2026 reveal, with one critical difference from its C-Class sibling: the M177 4.0-litre twin-turbo V8 is back, paired with 48V mild-hybrid electrification rather than a full plug-in system.
The four-cylinder C63 didn't sell. The CLE 63 is how AMG fixes it without admitting it.
Why the CLE gets the V8
The CLE platform is bigger than the C-Class and shares its bones with the E-Class — meaning the engine bay was always going to be large enough to swallow the M177. The C-Class wasn't. AMG's hand was forced on the C63 by packaging, the story goes; the CLE 63 simply doesn't have that constraint.
Power figures floated in the German press point to around 612 hp / 850 Nm, with 0–100 km/h in the low-3-second range and a top speed pushed to 320 km/h with the AMG Driver's Package. That'd put it squarely between the CLE 53's 449 hp and the old C63 S Coupe's 510. More importantly, it'd give buyers something the CLE 53 can't: the noise.
What's likely changing visually
- Panamericana grille with a wider centre slat, matching the recently-refreshed AMG GT and SL
- Larger air intakes in the lower bumper to feed the V8's coolers
- Quad round AMG exhaust outlets instead of the CLE 53's rectangular tips
- AMG Performance forged wheels at 20" standard, 21" optional
- A discreet "V8 BITURBO" badge on the front fenders — a nod to the M177 buyers who feel like they've been waiting two generations
Timing
If the rumors hold, expect a reveal in Q3 2026 with European deliveries in early 2027. North America gets it for the 2028 model year, badged simply AMG CLE 63 S to slot above the inevitable CLE 53 facelift.
Our take
The C63 four-cylinder wasn't wrong on paper — it was wrong on character. The CLE 63 V8 is Affalterbach quietly admitting that engineering excellence and brand promise aren't the same thing, and that the people writing $90,000 cheques for AMG coupes wanted the engine they paid for, not the engine that scored best on the EU drive cycle. If this lands the way the rumors suggest, it's the most important AMG launch since the GT.
