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

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.
