2027 Mercedes-AMG GLC53 4Matic+: A Return to the Straight-Six
Mercedes-AMG is poised to reintroduce a straight-six engine to the GLC range with the 2027 Mercedes-AMG GLC53 4Matic+. Scheduled for release in 2027, the GLC53 replaces the existing GLC43 and GLC63 S models, offering a potent combination of performance and styling [Hagerty].
Engine and Performance
The heart of the GLC53 is a 3.0-liter inline-six engine, turbocharged and supercharged, delivering 443 horsepower between 5,800 and 6,100 rpm and 443 pound-feet of torque from 2,200 to 5,200 rpm. An overboost function temporarily increases torque to 472 pound-feet for 10-second bursts [Hagerty], [Mercedes-Benz USA]. This engine utilizes a regular turbocharger alongside an electric auxiliary compressor, functioning as an electric supercharger [Hagerty].
This powertrain is as well slated for integration into the C-Class [Hagerty]. The engine features a new cylinder head with an updated intake cam, redesigned intake and exhaust systems, and works in conjunction with an integrated starter-generator as part of a 48-volt electrical system [Hagerty].
Drivetrain and Handling
The GLC53 features AMG Performance 4MATIC+ fully variable all-wheel drive, with an optional electronically controlled limited slip rear differential [Mercedes-Benz USA]. It also includes an available drift mode [Hagerty], [Mercedes-Benz USA]. AMG Air Ride Control suspension has been tuned for sharper cornering and improved ride comfort.
Exterior and Availability
The 2027 AMG GLC 53 will be available in both SUV and Coupe body styles [Mercedes-Benz USA]. Exterior features include 21-inch matte black AMG forged alloy wheels, glossy black brake calipers with white AMG logos, an enlarged front splitter, and an AMG lip on the rear spoiler (SUV) or tailgate (Coupe) [Mercedes-Benz USA]. The vehicle is expected to arrive at U.S. Dealerships in the second half of 2026 [Mercedes-Benz USA].
