The new Mercedes-AMG GT 4-door gets a bigger grille and a £179,325 price tag
The facelifted Mercedes AMG GT 4-door is available exclusively in 831bhp 63 S E Performance guise, sporting a series of design and tech updates
Mercedes-AMG’s GT 4-door is a saloon version of the firm’s Porsche 911 rival by name, if not by nature. The GT 4-door isn’t a genuine sports car under the skin (it shares its platform with the Mercedes E-class), but for 2023, the model has gained a new look designed to strengthen its visual ties to the latest AMG GT.
At the front, AMG’s Panamericana grille has been extended with a new lower section to feed air to the radiators, mirroring the AMG GT sports car. A pair of vertical outer vents in the front bumper also draw from the saloon’s two-door namesake, and a subtle new LED running light design has been applied at the rear.
The updated supersaloon is exclusively available in flagship GT63 S E Performance form at present, and its £179,325 asking price positions it well beyond alternatives from BMW and Porsche. In fairness to Mercedes, its performance is also in an entirely different category to those rivals – even if the powertrain remains the same as the outgoing model.
AMG’s ubiquitous 4-litre twin-turbo V8 lies under the bonnet, generating 630bhp. In this application, the engine is augmented by an electric motor housed in a rear transaxle that boosts power to a pulverising 831bhp, with torque rated at 1032lb ft. The combustion engine is mated to a 9-speed MCT transmission, with the electric motor driving through a two-speed gearbox and an e-differential at the rear.
Performance figures for the updated GT 4-door haven’t been officially announced, but its 2.9sec 0-62mph sprint and 196mph top speed will almost certainly remain unchanged. There’s no word on efficiency improvements for the electric drive system either, so expect the same 8 mile range and 81mph top speed when running in EV mode.
With a 6.1kWh battery pack mounted above the rear axle, the GT63 S E Performance has better weight distribution than non-hybrid versions, with twin-chamber air springs and adaptive dampers to help manage its considerable 2.3 ton mass. A ceramic composite braking system and rear-wheel steering also make up the suite of chassis electronics.
Inside, the updates centre around Mercedes’ latest MBUX infotainment software, which now features configurable AMG-specific displays. A wireless charger has also been installed for rear seat passengers, along with a standard-fit electric sunroof.
