Ultra-Rare Mercedes-AMG CLE 63 Coming With M4-Beating Muscle

The most potent Mercedes CLE Coupe you can buy right now is the CLE 53. This AMG model’s 3.0-liter six-cylinder turbocharged mill makes 443 horsepower, which is plenty, but it also leaves room for an even more powerful ‘63’ model higher up in the lineup. We now know just how powerful—and exclusive—this CLE will be, thanks to information obtained by Automotive News. A special-edition CLE 63 two-door is on the way and will pack 646 hp, but production will be limited to just a few units globally. Fortunately, it’s not the only new AMG on the way.

Limited CLE 63 Likely to be V8-Powered

The news comes from Sindelfingen, Germany, where Mercedes-AMG unveiled a new lineup of hot models to U.S. and Canadian dealers. The CLE 63 two-door coupe in question will be limited to just 30 units globally, so even fewer of these are destined to be available for U.S. buyers. While the engine itself wasn’t confirmed, the 646-hp output suggests it will be one of AMG’s V8s. This is less than the 671 hp made by the C63’s four-cylinder, but that’s a heavy plug-in hybrid that needs the extra grunt. We also know Mercedes plans to phase out the unloved four-pot in the C63, and there’s little chance of the CLE 63 getting two fewer cylinders than the CLE 53.

Earlier this year, Mercedes-AMG teased the Mythos, a high-performance coupe based on the CLE. Mythos is the company’s sub-brand for ultra low-volume performance models, so the production run of just 30 CLE 63 Coupes fits with that. A previous report suggested the Mythos AMG CLE would use a version of the new V8 in the S-Class, which uses a racing-inspired flat-plane crank. Whatever V8 the new CLE 63 uses, it’ll be a beast in a straight line; the older C63 S with a 503-hp V8 rockets to 60 in under 60 mph, for some perspective.

It remains to be seen if a regular CLE 63 to slot between the CLE 53 and likely CLE 63 Mythos will arrive and how powerful that will be.

Other AMG Models On The Way

At the same meeting, dealers also got a first look at the new AMG G63 Cabriolet. Due in 2028, it will be the first drop-top version of the G-Wagen in the USA and will be powered by a twin-turbo V8.

Three electric models bearing the GT 63 moniker are also on the way. They include a coupe for early 2027, a crossover for late next year, and a sporty coupe-style SUV that’s expected late in 2028. An “aggressive, yet elegant” design language for these models marks a conscious effort to move away from the rounded styling of existing Mercedes EVs. The coupe will be able to cover over 400 miles on a full charge, and all will have powerful axial flux motors, but no outputs were mentioned.

Finally, a halo GT Black Series will join the AMG lineup at some point. We haven’t seen one of these since the Mercedes-AMG GT Black Series produced from 2021. These models sit above standard AMGs, boasting more extreme performance and modifications suited for aggressive track driving.

What It Means

After a few years of gas-powered Mercedes-AMGs losing their edge with four-cylinder hybrid powertrains and AMG EV designs that failed to resonate, the performance division of the brand is looking to get back on track. BMW’s M division easily outsold Mercedes-AMG last year, and many believe this is largely because M products didn’t stray as far from the formula that has worked for so many years.

The CLE 63 will mark a return for smaller V8-powered Mercedes coupes, while the G63 Cabriolet and GT 63 EVs will see the performance brand branch into new territory. It only takes a few solid products to turn things around, and Mercedes-AMG looks on track to regain the respect and admiration it enjoyed in the 2000s and 2010s.
