Mercedes-Benz C63 AMG GT
The Mercedes-AMG GT 4-Door Coupé is an executive car (E-segment) introduced in 2018 by Mercedes-AMG marketed as a five-door variant of the AMG GT two-door sports car.
Despite the name and style, the car is not based on the sports car, but rather on the E-Class (W213) and CLS-Class C257. Its performance chassis, however, is closely related to E63 wagon, and is featured by the AMG-specific rear frame and a different front axle for better kinematics.
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 21 hp (16 kW) and 184 lb⋅ft (249 N⋅m) 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 CLS53. 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.
