2027 Mercedes-AMG GLC53 First Look: Hello, Inline-6 Engine

Mercedes-Benz has already shown us the all-new 2027 GLC, riding on a new platform with promises of multiple powertrains and variants. And now we see one of those spin-offs: the 2027 Mercedes-AMG GLC53 that delves into the performance realm with a choice of SUV or coupe body styles when it goes on sale in the U.S. in the second half of 2026. It aims to take leadership in the segment.

The AMG is distinguished by its front fascia with a larger front splitter up front, as well as a larger lip on the rear spoiler on the roof (SUV) or trunklid (coupe) and a diffuser in glossy black.

The biggest change is the turbocharged four-cylinder engine that has been a Mercedes mainstay is gone. It is being discontinued because it will not meet future emissions regulations.

So, powering the 2027 GLC53 is Mercedes’ 3.0-liter turbocharged inline six-cylinder engine that has been given the AMG treatment. The result is a 443-hp, 443-lb-ft powerplant with a powerful exhaust note and an overboost function to deliver an extra adrenaline burst. The overboost provides 472 lb-ft of torque for 10 seconds to help make sprints in the passing lane even quicker.

Yup, The GLC Has a Drift Mode

The engine is paired with the AMG nine-speed automatic transmission and drives all four wheels via 4Matic all-wheel drive as standard. Customers can choose to add an electronically controlled limited slip differential that includes a Drift Mode and the ability to make the vehicle rear-wheel drive. These are firsts for an AMG SUV and come as part of the AMG Dynamics Plus package.

The I-6 has a turbocharger as well as an electric auxiliary compressor to help smooth the torque curve. The modified engine has a new cylinder head and intake camshaft. It is also deliberately louder, with an exhaust note that varies across the five available drive modes. The AMG Dynamic Plus package also adds a Race drive mode.

The second-generation integrated starter-generator takes on hybrid functions by supporting the engine at lower speeds with 23 hp and 151 lb-ft while also helping with energy recuperation and smoother start-stop transitions.

Standard rear-axle steering provides more agile turn-in, better handling, and a reduced turning circle.

Mercedes says the 2027 model ups the towing capability for the U.S. market (no figures yet) and is compatible with a Class II hitch.

Golden Accents Package for 2027 Only

A treat being offered: a special Golden Accents package, but only for the 2027 model year. It comes with a choice of an Obsidian Black Metallic or Graphite Grey Magno exterior with gold details for contrast, as well as AMG graphics.

The package also includes a lengthy list of equipment. It has 21-inch forged AMG cross-spoke wheels in matte black with gold rim flanges and center cap details. The brake calipers are black with white AMG branding. The fuel filler cap is silver chrome with black AMG design elements. Inside are AMG sport seats in black leather as well as contrast stitching throughout the cabin, right down to the floor mats. The carbon fiber trim is also woven with gold metallic threads. The door sill panels have an AMG logo illuminated in white.

The AMG Night Package is pretty much what you would expect: high-gloss black mirror housings and trim, dark chrome tailpipe trims and door handles, and an AMG emblem on the hood and badging on the rear in black chrome.

The 2027 Mercedes-AMG GLC53 will be available later in the second half of the year. Final pricing will be released closer to its on-sale date.
