Mercedes-AMG GLC 53 unveiled, to come in both SUV and coupe forms

Mercedes-AMG has unveiled the new GLC 53 with a revamped 3.0-litre inline-six, mild-hybrid tech and drift mode, marking the return of six-cylinder power to the performance SUV and coupe lineup.

Mercedes-Benz has taken the wraps off the new AMG GLC 53, reintroducing a six-cylinder engine to the performance SUV and Coupe range. Set to be offered globally in both body styles, the new 53 badge effectively reshapes the AMG GLC line-up, replacing the outgoing 43 and 63 variants in international markets.

At the core of the AMG GLC 53 is a comprehensively updated 3.0-litre inline six-cylinder turbo-petrol engine paired with a 48V mild-hybrid system. The engine produces 443hp and 600Nm, with torque rising to 640Nm for 10 seconds via an overboost function at 5,200rpm. The integrated starter-generator contributes an additional 23bhp and 205Nm, while also enabling energy recuperation and smoother start-stop operation.

Although based on AMG’s existing six-cylinder unit, the engine has undergone significant changes. It now features a new cylinder head with optimised intake and exhaust ports, a revised intake camshaft, a larger intake system and an upgraded intercooler. Boost pressure stands at 1.5 bar (21.8psi), and the electric auxiliary compressor has been enhanced for longer and more sustained operation, sharpening throttle response across the rev range.

Power is sent to all four wheels through AMG’s nine-speed SPEEDSHIFT TCT automatic transmission and the fully variable AMG Performance 4MATIC+ all-wheel-drive system. With Race Start (part of the optional AMG Dynamic Plus Package), the GLC 53 sprints from 0-100kmph in 4.2 seconds. Top speed is electronically limited to 250kmph, extendable to 270kph with the AMG Driver’s Package.

In a first for an AMG SUV, the GLC 53 can be equipped with an electronically controlled rear-axle limited-slip differential along with Drift Mode. Available through the AMG Dynamic Plus Package, this setup allows the SUV to operate in rear-wheel-drive mode on closed courses, underscoring its performance intent.

The standard AMG Performance 4MATIC+ system can vary torque distribution continuously between the front and rear axles. Under low-load conditions, the front axle can decouple to improve efficiency, while sportier settings bias torque rearwards for a more engaging drive.
