Mercedes-AMG GT 4-Door Coupé

The Mercedes-AMG GT 4-Door Coupé is an executive car (E-segment) introduced in 2018 by Mercedes-AMG. It is marketed as a five-door variant of the AMG GT two-door sports car. Despite the name and style, the GT 4-Door Coupé is closely related to the E 63 AMG with its performance chassis, and is featured by the AMG-specific rear frame and a different front axle for better kinematics.

Specifications

The design of the GT 4-Door Coupé was mainly influenced by the Mercedes-Benz AMG GT Concept introduced a few years before series production. The AMG GT 4-Door Coupé uses a front-engine layout with rear-wheel-drive or 4MATIC+ fully variable all-wheel-drive (rear-biased), and is available with either a 3.0 L '' M256'' turbo/supercharged inline-six engine or a 4.0 L '' M177'' twin-turbocharged V8 engine. The inline-six engine features a conventional turbocharger as well as a mild hybrid system that Mercedes-Benz calls "''EQ Boost''", which uses an electrically driven supercharger and a 48 volt electric motor that when combined, produce an extra and of torque in addition to the petrol engine when it is not powering the electrical system. This system traces its roots back to the Mercedes CLS 53. The car utilises the rear anti-roll bar to increase chassis stiffness, as well as active aero, including an electronically adjustable rear spoiler and electronically operated front louvers in the front grille, that can open and close to manage airflow through the radiator from the AMG GT R flagship sports car.

The GT 63 is a high performance, better equipped variant of the GT 4-Door and features the AMG M177 4.0L twin-turbocharged V8 engine, which produces and . It has a claimed acceleration time of 3.4 seconds and a top speed of as tested by the manufacturer. The GT 63 also has an optional selectable "Drift Mode" which directs power solely to the rear wheels. The car comes standard with an electronically controlled limited-slip rear differential and rear-wheel steering, and features an MCT gearbox with a wet clutch to handle the extra power. The GT 63 uses AMG's multi-chamber air suspension for a sportier, more adaptive ride and has cylinder deactivation mode for increased efficiency.

Mercedes-AMG GT 63 S 4MATIC+

The GT 63S will reportedly accelerate from in 3.2 seconds and attain a top speed of as tested by the manufacturer. Auto Bild tested in 3.0 seconds, in 6.6 seconds and in 10.2 seconds.

Additionally, all of the equipment and features from the GT 63, as well as the selectable "Drift Mode", which directs power solely to the rear wheels, comes as standard on the GT 63S as well.

Mercedes-AMG GT 63 S E-Performance

The GT 63 S E-Performance is the top-of-the-line, flagship variant of the GT 4-Door. It is the first car to be launched under Mercedes’ new E Performance brand. It features the same 4.0L M177 Biturbo V8 engine, with the same electric motor powertrain as the Mercedes-Benz AMG GT Concept. The engine alone produces from 5,500 to 6,500 rpm, and from 2,500 to 4,500 rpm. It is supplemented by a rear-mounted electric motor that spins up a maximum of 204 PS for 10-second blasts and can continually provide 95 PS, and of torque. Its combined power output is , with of torque, making it the most powerful AMG GT 4-Door model ever made. The sprint time can be achieved in less than three seconds. The powertrain is named ‘V8 Biturbo E-Performance’. As for the PHEV system, the 6.1 kWh battery pack with the electric motor can commit to a pure EV range of 12 km at speeds of up to .
