AFFALTERBACH, Germany — In a move that enthusiasts are hailing as a “return to sanity,” Mercedes-AMG has officially unveiled the new GLC 53 4Matic+, dramatically pivoting away from the controversial four-cylinder experiment that has defined the current generation’s performance SUVs.
The headline for the 2027 model year is the resurrection of the 3.0-liter inline six-cylinder engine. Replacing both the four-cylinder GLC 43 and the complex, heavy GLC 63 S E Performance plug-in hybrid in many markets, the new GLC 53 aims to recapture the “soul” that critics argued was lost when the brand downsized its powertrains.
Mercedes’ most popular SUV is getting a new AMG variant. Meet the GLC 53 AMG, available in SUV and coupe-SUV flavors.

Engineering a Comeback
The heart of the new machine is a heavily revised “M256 Evo” engine. While similar to the unit found in the CLE 53, this version features a larger intercooler, a high-volume intake system, and an upgraded electric auxiliary compressor that now delivers nearly continuous boost.
The results are formidable: the turbocharged straight-six produces 443 horsepower and 443 lb-ft of torque. For those seeking an extra surge, a 10-second “overboost” function pushes torque to 472 lb-ft. Combined with a 48-volt mild-hybrid system that adds a 23-hp “kick,” the GLC 53 can rocket from 0 to 100 km/h (62 mph) in just 4.2 seconds.
SUV “Shenanigans”: The Debut of Drift Mode
In an unprecedented move for an AMG SUV, Mercedes has introduced a dedicated “Drift Mode.” Previously reserved for the brand’s low-slung sedans and coupes, the system utilizes a fully variable 4Matic+ all-wheel-drive setup and an electronically controlled rear-axle limited-slip differential. When engaged, the front axle is completely decoupled, sending 100% of the power to the rear wheels for controlled slides, a feature Mercedes-AMG describes as a first for their crossover lineup.
Standard equipment has also been bolstered to justify the “53” badge, including rear-axle steering for enhanced agility and “Ride Control” adaptive suspension. For the auditory purists, a new exhaust system with special resonators has been tuned to provide the deep, guttural growl that the previous four-cylinder models lacked.
Limited Edition Luxury
To celebrate the six-cylinder’s return, Mercedes is offering a “Golden Accents” launch edition for the first year. Available in Obsidian Black or Graphite Grey, the special edition features “Techgold” highlights on the 21-inch forged wheels and exterior trim, mirrored inside by carbon fiber weave infused with gold thread.
While official pricing for the European and North American markets has yet to be finalized, the GLC 53 is expected to hit showrooms in late 2026. For the AMG faithful, the message is clear: the cylinders are back, and the spirit of Affalterbach is once again firing on all six.
