Article Abstract
- C63 is being discontinued: AMG says the two.0T can’t meet Euro 7.
- C53 takes over: 3.0L inline-six, ICE-only—extra M340i/M350 rival than M3 rival.
- M3 advantages: 2028 M3 (G84) retains a six (seemingly mild-hybrid), 525+ hp rumored; no handbook and presumably xDrive-only.
The C63’s days are numbered, as Mercedes-AMG CEO Michael Schiebe has confirmed that the M3 rival is headed for retirement. In an interview with Edmundsthe outgoing Affalterbach boss defined why the flagship C-Class is being axed. The issue lies with its four-cylinder gasoline engine, however apparently not the shoppers’ lack of enchantment for the downsized powertrain. We’re instructed that the two.0-liter turbo unit can’t be made compliant with the upcoming Euro 7 laws.
The excellent news is that an AMG-tuned C-Class will dwell on, nevertheless it gained’t absolutely substitute the outgoing C63. Mercedes plans to introduce a milder C53 mannequin powered by an inline-six engine, borrowed from the BMW M440i-rivaling CLE 53 Coupe and Cabriolet. In contrast to the plug-in hybrid C63, the C53 will keep on with a combustion-only setup constructed round a 3.0-liter engine, information that ought to please purists.
Within the CLE 53 fashions, this six-cylinder presently delivers 443 hp and 413 lb-ft (560 Nm). If these figures carry over unchanged, Mercedes-AMG will struggle the next-generation 3 Sequence in M Efficiency kind moderately than go head-to-head with a full-fat M3. Studies recommend the M340i can be changed by an M350 producing 417 hpgiving the range-topping G50-generation 3 Sequence an additional 31 hp over immediately’s M340i.
In consequence, the M3 G84 arriving in 2028 gained’t have to fret in any respect about an AMG C63 rival. BMW has already confirmed it would retain a six-cylinder engine and has hinted at mild-hybrid help. Our sources declare the gas-powered M3 will exceed 525 hp, nevertheless it gained’t supply a handbook gearbox. Rear-wheel drive might also be dropped in favor of an xDrive-only configuration, although nothing is official at this level.
Might the C63 ever make a comeback? It’s cheap to count on Mercedes to ultimately handle the absence of a real range-topping C-Class. AMG is creating an all-new V8, although its utility within the C-Class hasn’t been confirmed. On condition that the present W206 technology is already 5 years outdated, a V8-powered C63 appears unlikely. By the point a successor arrives, assembly emissions laws with an eight-cylinder setup can be an infinite problem.
And what about Audi? The model is getting ready to unveil the brand new RS5 later this month. It’s anticipated to characteristic a plug-in hybrid powertrain, seemingly centered round a V6. Audi plans to supply the flagship as each a five-door liftback and an RS5 Avant aimed squarely at Munich’s Touring.
