2019 Mercedes-AMG GT 4-Door: The More-Door AMG - Review
AMG's very own four-door is its most powerful model yet.

The first ever AMG-fettled Mercedes-Benz was a four-door car, and in the Affalterbach tuning outfit’s early days, four-door Benzes were the exclusive recipients of its ministrations. More recently, of course, AMG has visited its special brand of magic on Mercedes models of all sizes and body configurations, from the A-class subcompact to the G-wagen SUV. But to date, the purpose-built AMG models have been two-door sports cars and roadsters. We’ve known for some time—certainly since the debut of AMG’s four-door concept car at last year’s Geneva auto show—that an AMG-exclusive four-door was in the works.

Now, it has finally been revealed. Its official name, the Mercedes-AMG GT 4-Door coupe, may be something of an anticlimax, but there’s plenty to get excited about here. First, though, a bit of clarification: Despite a model designation that suggests this new entry is an AMG GT coupe writ larger, the model is actually based on the E-class sedan’s MRA longitudinal-engine, rear-wheel-drive architecture. One look at it, though, and it’s clear that this is not merely a more sportified E63. The AMG GT 4-Door has its own body, with a low-slung silhouette and a steeply raked windshield. Out front, a vertical-bar grille further establishes a visual connection to AMG’s sports car. At the rear, the active trunklid spoiler adjusts its angle based on vehicle speed; on V-8 models a more extreme aerodynamics package is optional, which brings a larger front splitter, a modified rear diffuser, and a fixed rear wing that is manually adjustable.

Most Powerful AMG Yet
The car debuts in a trio of familiar model designations, and the three-engine lineup includes inline-six and V-8 offerings, all fed with forced induction. The GT53 is the opening gambit and uses the carmaker’s recently introduced turbocharged inline-six. It’s supplemented by an electrically driven supercharger and a 48-volt electric motor (a setup first seen in the new CLS53). As in the CLS53, the 3.0-liter powertrain produces a maximum of 429 horsepower and 384 lb-ft of torque, with the electric motor contributing up to 21 ponies and 184 lb-ft. In combination with a nine-speed torque-converter automatic and 4Matic+ all-wheel drive, the combo is good for a 4.4-second sprint to 60 mph and a 174-mph top speed, according to AMG.

Like other AMGs wearing the “63” designation, the GT63 is powered by a twin-turbo 4.0-liter V-8. It’s paired with a slightly different nine-speed automatic—this one replaces the torque converter with a multiplate clutch pack—that incorporates AMG’s Race Start function. In the 4-Door model, output is 577 horsepower and 553 lb-ft. (That matches this engine’s numbers in the wildest version of the coupe, the track-monster AMG GT R.) AMG claims the GT63 can charge to 60 mph in 3.3 seconds on its way to a top speed of 193 mph.
Naturally, there’s also a “63 S” version. That variant turns up the wick to 630 horsepower and 627 lb-ft—meaning that the most potent AMG GT 4-Door exceeds the output of the two-door sports car, not to mention that of the 603-hp E63 S, which currently holds the title of fastest four-door sedan at our Lightning Lap test. In this car, the S’s extra oomph shaves 0.2 second off the factory zero-to-60-mph time and adds 2 mph to the terminal velocity, for new figures of 3.1 seconds and 195 mph. In both GT63 cars, the 4Matic+ all-wheel-drive system features an electronically controlled limited-slip rear differential; a selectable Drift Mode, in which torque is directed solely to the rear wheels, is standard on the GT63 S and optional on the normal GT63.
Brakes of Bronze

All that go requires plenty of whoa, and AMG seems to have spent a considerable amount of energy on the GT 4-Door’s brakes. Or at least on the color of their calipers, which come in four different hues. The GT53’s internally vented and perforated rotors are squeezed by relatively humble silver-painted calipers. In the GT63, flashier red units—six-piston front and single-piston rear—grip larger rotors. The GT63 S has the same hardware, but the calipers are an even more visually arresting yellow. The V-8 cars can be further upgraded with carbon-ceramic rotors, whose bronze-painted calipers mark them as the ultimate setup.
The 63-series cars ride on air springs (AMG Ride Control+), while the 53 version uses steel coils and adaptive dampers. Four-wheel steering is another exclusive feature of the V-8 model’s chassis. Below 62 mph, the rear wheels turn opposite of the fronts; at higher speeds, they turn in phase.

2019 Mercedes-AMG GT 63 S 4MATIC+ data at a glance:

Engine: 4.0-litre V8 with direct injection and twin turbochargers
Displacement: 3982 cc
Output: 470 kW (639 hp) at 5500 - 6500 rpm
Peak torque: 900 Nm at 2500 - 4500 rpm
Drive system: AMG Performance 4MATIC all-wheel drive with variable torque distribution and Drift mode
Transmission: AMG SPEEDSHIFT MCT 9G
Acceleration 0-100 km/h: 3.2 s
Top speed: 315 km/h

The electro-mechanically controlled clutch of the AMG Performance 4MATIC+ all-wheel-drive system connects the permanently driven rear axle variably to the front axle. The best possible torque split is continuously computed according to the driving conditions and driver's input. The transition from rear-wheel to all-wheel drive and vice versa is seamless, as the intelligent control is integrated into the overall vehicle system architecture. Alongside traction and lateral dynamics, the all-wheel drive also improves the longitudinal dynamics for even more powerful acceleration.

It is still possible to drift thanks to fully variable torque distribution. To this end, the S version of the four-door AMG GT features Drift mode as standard. It is also available for other models as part of the optional AMG DYNAMIC Plus Package. Drift mode can be called up in the "RACE" drive program using the shift paddles, provided that ESP® is deactivated and the transmission is in manual mode.

The multi-link rear suspension with five links makes for impressively precise suspension and high rigidity. Here again, the consistent implementation of a lightweight construction leads to reduced unsprung masses: three of the five wheel-guiding links as well as the wheel mounts are made of forged aluminium. The driving dynamics benefit from the increased track width, the larger tyre dimensions and the optimised fine-tuning of the wheel-guiding elastomer bearings. Newly developed elastokinematics guarantee everyday comfort as well as high-precision driving and great vehicle dynamics.

To improve traction and dynamics, the eight-cylinder models are equipped as standard with an electronically controlled differential lock on the rear axle. The slip is thus suppressed at the inner wheel on bends, ensuring optimum grip. The driver is therefore able to accelerate out of corners earlier and with more power thanks to the improved traction. The vehicle remains more stable when braking from high speed, while the limited-slip differential also improves traction when accelerating from a standstill. The electronically controlled rear-axle differential lock is also part of the optional AMG DYNAMIC PLUS Package and is available in this way for the six-cylinder models of the four-door AMG GT.

The rear-axle differential also has a new specially reinforced mount to improve the NVH (noise, vibration, harshness) characteristics. As on the AMG GT R, an anti-roll bar made of tubular material reduces the overall weight of the rear axle.

The new 3.0-litre inline 6-cylinder petrol engine and the proven AMG 4.0-litre V8 biturbo engine cover a performance spectrum ranging from 270 kW (367 hp) to 470 kW (639 hp). They deliver incredible driving performance despite offering contemporary levels of efficiency. AMG-specific technologies such as the fully-variable 4MATIC+ all-wheel drive system and the rapid-shifting AMG SPEEDSHIFT 9G transmission with torque converter (TCT = Torque-Clutch Transmission) on six-cylinder models and a wet start-off clutch (MCT = Multi-Clutch Transmission) on eight-cylinder models serve to increase performance levels. As with the two-door AMG GT, the active aerodynamics with AIRPANEL active air control system in the front apron and extendible rear spoiler form the basis for high aerodynamic performance.

The interior is equipped with a number of modern high-tech features: innovative control panels such as the eight high-resolution display buttons in the centre console can be intuitively operated. The AMG Performance steering wheel with the new AMG steering wheel buttons (standard on the AMG GT 63 S 4MATIC+), the AMG seats and the fully-digital Widescreen Cockpit (standard on eight-cylinder models, optional for six-cylinder vehicles) with the new "Supersport" display style underscore the vehicle's dynamic character. MULTIBEAM LED headlamps, the EASY-PACK tailgate, Burmester® Surround Sound system (standard on the eight-cylinder models) and the 64-colour ambient lighting increase the car's everyday comfort.
