the next mercedes amg c63 may get a larger engine but no v8

Mercedes threw a four-cylinder engine at the C63 a while back, ending the iconic V8’s long run in the car and effectively tanking its appeal for enthusiasts. A lot of words have been written about the car in the time since, and the automaker appears to have listened, though it’s not making the exact changes many had hoped. The next C63 may get a bigger engine, but it’s not likely to be a V8.

A Mercedes board member told Auto Express that, “We will have some options where we had a four-cylinder, which will also be available as a six-cylinder going forward. There may or may not be a hybrid, it might be pure ICE, maybe. We’ll let you know when we are there.”

The current four-cylinder engine has loads of tech, including a trick electric turbocharger, plug-in hybrid tech, and other goodies, but even with its prodigious power and speed, it could never match the V8’s ferocity, engagement, and sound. A mild-hybrid inline-six or a similar engine could help with some of that, but the V8 noises will still be absent.

Of course, Mercedes may change course entirely and ditch the C63 name in favor of a tamer C53, which would align with the six-cylinder powertrain. Hybrid power is also almost a given, with tightening Euro emissions regulations driving the ship for many automakers. Whatever the change, we won’t have long to wait, as the next C63 update is expected to arrive in mid-2026.

Larger engine is nice to have; larger grille emblem is must-have.

I haven't read anything in this reporting that that states the V8 is not coming back for sure. It just sounds like the six-cylinder replacements will be around first.

If the CLE63 is getting a V8 I expect the top C-Class will be getting one back as well. I'm not sure why journos are acting like the C/E hierarchy won't follow the CLE but 🤷‍♂️

TheEndlessEnigma I'm sure the rise in driving infractions in Minnesota has nothing to do with all the learing centers.
Plaincraig 06 PT Cruiser 214k miles. 24MPG with a 50/50 highway city driving. One new radiator was the only thing replaced from failure at 80k.Regular maintenance and new radiator hoses and struts at 100k. Head gasket failed blew out the camshaft seals and the rear seal failed too. Being able to remove the backseats was wonderful. The ride was fine. Took an exit ramp and twice the rated speed and some kid in a Mazda 3Speed rolled down his window and asked what I done to make it handle like that. I said "Its all stock and Walmart tires. I know how to drive not just go fast."
Flashindapan Corey, I increasingly find your installments to be the only reason I check back here from time to time.
SCE to AUX The first couple generations of Prius were maligned by association with a certain stereotype owner. But you can't deny their economy and reliability is the envy of the automobile world. It's rare for an EV to match the TCO of a Prius. From personal experience, the first-gen Nissan Leaf. Yes, they looked like a frog and their batteries degraded, but the car was ultra-reliable, well-built, and smooth driving, and was a good introduction to electric motoring for its time.
DungBeetle62 Mercury Capri. It was never conceived to be an updated Lotus Elan/Brit RWD Roadster with Japanese reliability as the Miata was. If you just treated it as a more fun and airy commute than the Tracer/323 its bones came from - it was pretty quick with the turbo (for the era) and enjoyable. And you still had some Mazda reliability under the skin. Yes, I owned one. But let's just say I'm not perusing Bring a Trailer looking for used examples in decent shape.
