2019 Mercedes-AMG GT 4-Door Coupé
The Mercedes-AMG GT 4-Door Coupé is many things, but it's anything but simple. In a brief description we could say it's a faster four-door version of a two-door car (AMG GT). Or we could say it's a faster version of the CLS63, another fast four-door coupé. Or, since it's based on the E-Class platform, it's a smaller, coupé-style, faster version of the E63 S sedan.
So trying to figure out its place in the Mercedes lineup is not an easy task. The North American Mercedes family spans over 86 different models, with each branch of the German tree intertwining like an invasive Kudzu plant. Soon, the overlap will be too much, and every new model will be some kind of crossed up coupe-not-coupe high performance blob.
Where does that leave the AMG GT 4-Door? If you don't consider its performance, nowhere. It'd be a more expensive and less practical E-Class AMG. But if you do open its front hood you'll see it's the fastest road-legal Mercedes currently in production. And for some, that's all it takes to stand out.
Like all current high-end Mercedes AMG cars its most defining features lies under the front hood. Historically, AMG saloons have more power and grunt than its competition and the AMG GT 4-Door is no exception. For GT63 and 63 S models, AMG deploys their crown jewel M178 4.0-liter twin-turbo V-8 petrol engine. GT63 S models produce 630 horsepower and 664 lb-ft of torque for a clean zero-to-100 kmh in 3.2 seconds with a terrifying top speed of 196 mph (315 kmh). GT63 models make do with 576 horsepower and 590 lb-ft of torque for a zero-to-100 kmh in 3.4 seconds with a 193 mph (310 kmh) top speed. Both V-8s feature cylinder deactivation for unnecessary fuel economy savings, active engine mounts (optional on GT63), and AMG SPEEDSHIFT MCT 9-speed wet-clutch automatic transmissions.
If you can't afford either V-8 the AMG GT53 4-Door is an entry level model into the new lineup (Entry meaning a starting cost of over $110,000). It uses a newly released powertrain involving an M256 3.0-liter turbocharged straight-six engine with 48-volt mild-hybrid technology. That means a 3.0-liter petrol unit outputting 429 horsepower and 384 lb-ft of torque assisted by an electric compressor unit for an additional 22 horsepower and 184 lb-ft of torque. Run this power through an AMG SPEEDSHIFT TCT 9-speed torque converter automatic transmission and you're looking at a zero-to-100 kmh in 4.5 seconds with a 177 mph (285 kmh) top speed.
To put its straight-line performance into perspective the GT63 S and GT63 is faster to 100 kmh than the AMG GT R; the fastest version of the 2-door car it's based on. We're sure Mercedes will be updating the AMG GT 2-door lineup with an even quicker model soon but for now, this four-door luxury cruise missile launches with the same ferocity as a Ferrari 599.
Drivetrain features for the AMG GT 4-Door are, predictably, carbon copies of the features offered on almost all the top-end AMG models. This includes standard 4MATIC+ all-wheel-drive with heavy rear wheel drive bias, rear-axle electronic limited slip differential (Standard on GT63 S, optional on GT63/53), active rear-axle steering (Standard on V-8s, optional on GT53), standard speed-sensitive electric steering, steel springs with adaptive dampers for GT53s, and multi-chamber adaptive air suspension for GT63/63 S.
All models come standard with electronically controlled vertical louvers mounted in the front apron similar to the AMG GT R. These louvers can open for improved engine cooling or close for more aerodynamic efficiency. An active wing sitting on the rear deck can also raise or lower for high speed stability. And if you desire more downforce, AMG offers an Aerodynamics package that adds front canards, a larger front splitter, modified rear diffuser, and a manually adjustable rear aerofoil (Optional in carbon fiber).
Brake sizes aren't listed yet but models with a V-8 will come from the factory with 6-piston fixed calipers in the front and single floating calipers in the rear. Those that wish to take the GT 4-Door to the track may opt for a ceramic brake disc option though the calipers stay the same. GT63/53 models wear 255/45 R19 and 285/40 R19 tires while GT63 S models use a larger set of 265/40 R20 and 295/35 R20 compounds. All models can upgrade to 275/35 R21 and 315/30 R21 Michelin Pilot Sport 4S tires for maximum three-season performance.
Scores of Settings
The interior cabin is lain with carbon-fiber-look trim, metallic surfaces, leather, and micro-suede. Its centerpiece is a dual set of 12.3-inch displays standard on V-8 models. AMG53s use a traditional analogue gauge cluster in front of the driver, though the digital screen is an available option. AMG also includes their latest performance steering wheel as standard featuring touch sensitive gesture controls, two configurable buttons, and two scroll wheels.
Drivers have many available settings to play with in the AMG GT including three steering modes (Comfort, Sport, Sport+), six drive modes (Slippery, Comfort, Sport, Sport+, RACE, Individual), and four AMG DYNAMICS agility modes (Basic, Advanced, Pro, Master) - the latter of which is chosen automatically based on the drive mode. AMG GT63 S models come with Drift mode (Optional on lower models) which fully disables the electronic stability control, sends all power to the rear wheels, and actives manual transmission control with paddle shifters. Just be sure to keep an extra set of rear tires at the ready. And for those that want to feel like Lewis Hamilton (Mercedes' words) the available AMG TRACK PACE package allows the car to collect and display over 80 driving parameters like braking, throttle, real-time telemetry, lap speed, steering angle, drift angle, zero-to-100 kmh times, and lateral acceleration.
Additional luxuries include optional seat massage, heated steering wheel, ambient LED lighting, and DRIVE PILOT (Lane keep assist, automatic cruise control, automatic forward emergency braking, ect) assist technologies. Rear seats come in three configurations; standard three-seat with 60/40 split folding, non-folding two-seat, or non-folding High-Class two-seat with integrated rear touchscreen. Rear trunk capacity is 13.9 cu-ft (395 liter) with 2.1 cu-ft (60 liter) underneath the trunk floor. If you're able to fold the seats down, total rear capacity tops out at 46.8 cu-ft (1324 liter). We don't recommend drifting with passengers in the rear.
Price to be announced. 2019 Mercedes-AMG GT 4-Door Coupés will be available in the U.S. summer 2018.
