Mercedes-AMG GLC 53: Six-Cylinder Engine Returns with Enhanced Power and Features











Mercedes-AMG is once again embracing larger engines, as evidenced by the introduction of the new GLC 53. This model, boasting a six-cylinder powerhouse, signals a strategic shift back towards more robust powertrains, distancing itself from the previous four-cylinder models that generated some controversy among enthusiasts. The vehicle's debut highlights Mercedes-AMG's commitment to performance and driving dynamics, while also acknowledging the evolving landscape of the automotive industry and consumer preferences.
Mercedes-AMG Reintroduces Six-Cylinder Power to GLC 53 Lineup
In a significant development for performance vehicle enthusiasts, Mercedes-AMG has officially revealed the new GLC 53, a high-performance crossover that reintroduces the robust six-cylinder engine configuration. This move comes after a period where some AMG models, such as the C63, transitioned to four-cylinder engines, a decision that sparked considerable debate within the automotive community. The new GLC 53 is equipped with an enhanced 3.0-liter inline-six turbocharged engine, designated as “M256M.” This upgraded powerplant delivers an impressive 443 horsepower and 443 pound-feet of torque. Notably, it also features an innovative overboost function that can temporarily elevate the torque output to 472 lb-ft for a duration of 10 seconds, providing an extra surge of power when needed.
Compared to its counterpart, the CLE 53, the GLC 53's engine showcases several key modifications. These include a redesigned cylinder head, an updated intake camshaft, a new intercooler, and a larger volume intake system, all contributing to its superior performance metrics. The vehicle is offered in both standard SUV and a sleeker "Coupe" body styles. Both versions are engineered for exhilarating performance, achieving 0 to 60 mph (96 km/h) in a swift 4.1 seconds. For those opting for the AMG Dynamic Plus Package, the top speed extends to 167 mph (270 km/h). To complement the return of the six-cylinder engine, Mercedes-AMG has fitted a new exhaust system with specially designed resonators, promising a more profound and engaging engine sound.
Power is efficiently distributed to all four wheels through a sophisticated nine-speed torque-converter automatic transmission. An optional electronically controlled limited-slip differential further enhances traction and handling. A standout feature of the new GLC 53 is its introduction of a drift mode, marking it as the first Mercedes-AMG crossover to offer this dynamic driving capability, though it is an additional option. Furthermore, the GLC 53 comes standard with rear-wheel steering, a technology that improves maneuverability and stability. At speeds up to 60 mph, the rear wheels can steer up to 2.5 degrees opposite to the front wheels, while at higher speeds, they turn up to 0.7 degrees in the same direction.
While the exact pricing details for the new GLC 53 have not yet been disclosed, it is anticipated to be positioned between the current GLC 43 and GLC 63 models, which are priced at $68,900 and $88,100, respectively. This launch reaffirms Mercedes-AMG’s commitment to internal combustion engines, even as the brand continues to develop its electric vehicle offerings. The company’s earlier plans for a rapid transition to an "electric-only" future by 2030 have been adjusted, acknowledging the enduring demand for traditional gasoline-powered vehicles.
The reintroduction of the six-cylinder engine in the Mercedes-AMG GLC 53 serves as a compelling signal from the brand: performance and driving excitement remain paramount. This strategic decision highlights Mercedes-AMG's responsiveness to consumer feedback and market dynamics, particularly after previous models with smaller engines didn't quite hit the mark with all enthusiasts. By bringing back a more potent and audibly engaging powertrain, Mercedes-AMG aims to rekindle the passion for its high-performance SUVs. This move also suggests a broader industry trend where, despite the strong push towards electrification, there's still a significant appreciation for the visceral experience offered by well-engineered internal combustion engines. It's a reminder that true driving pleasure often lies in the harmonious blend of power, sound, and dynamic capabilities.
