Overall verdict on the Mercedes-AMG GT 4-Door

"Mercedes-Benz is taking on the Porsche Panamera Turbo with the AMG-GT 4-Door. Powered by a 4.0-litre V8 engine and with a six-figure price tag, the ultra luxurious 4-Door is an extravagant purchase - but one we think is worth every penny."

As we'll see in this Mercedes-AMG GT 4-Door review, like the Porsche Panamera, this is a high priced, high class performance saloon designed to carry four people very quickly and in luxury. Inside it exudes quality. 


Fancy ambient lighting lets you pick from 64 colours and manages to look quite classy - not a given for colourful interior lighting - and drivers who really want to treat rear seat passengers can opt for the £3695 Rear Luxury Lounge package with its individual seats and a centre console with touchscreen display providing access to the infotainment.


Heated seats are standard in the back, while a respectable 395-litres of boot space is supplemented by an additional 60 litres under the boot floor. True, you’ll have to cut down on luggage if you’re looking to trade your Porsche Cayenne SUV in, but that’s a perfectly useable amount of space.


Just like the recent BMW 8 Series, the Mercedes-AMG GT 63 is a niche player that, in objective terms, doesn't make a great deal of sense. We really rate the Mercedes-AMG E 63 S and, for most buyers, that'll do a far better job of transporting the family at speed and in comfort. It's not as stylish, but is more spacious.


Unlike rivals like the BMW 8 Series and Porsche Panamera, the Mercedes-AMG GT 4-Door is only available with a hunking great petrol engine, meaning it's hard to justify for high mileages, too. If you're thinking objectively, though, you probably wouldn't be looking to spend £150,000 on a car in the first place. 

If you’re in the market for a Porsche Panamera-esque performance saloon or love the AMG-GT two-door coupe but need more practicality, this is the car for you. It’s a German uber-saloon that is utterly fast yet still comfortable and usable every day. 

There’s only the 63 AMG at the moment and the one to go for is the S. After all it’s 0.2 seconds quicker to 62mph which we all need.

The obvious rival here is the Porsche Panamera. There are more versions of the Panamera available, including a diesel, but it’s the Turbo versions which rival the Mercedes-AMG GT 4-Door. You can also look at the Maserati Quattroporte for a bit of Italian flair. There’s also the Audi RS7 Sportback and the BMW M8 Gran Coupe. Basically, a lot of German stuff.

Comfort and design: Mercedes-AMG GT 4-Door interior

"You sit slightly higher than you may expect, but there’s plenty of electric adjustment in both front seats. Things are pretty good in the back, too. Even for adults, there’s a respectable amount of head and legroom. "

Children might moan about the relatively high window line, but there won’t be any complaints about how comfortable the seats are.

Mercedes-Benz has taken the title of ‘best interiors in the business’ from Audi in recent years, and its Mercedes-AMG GT 4-Door combines a centre console similar to that found in the two-door AMG-GT with the classy features of bigger and newer models like the Mercedes-Benz E-Class

There’s a premium Burmester surround sound system as standard, as well as a 12.3-inch colour display incorporating DAB radio and 3D navigation as well as Apple CarPlay.

The boot capacity of up to 395 litres is supplemented by around a further 60 litres beneath the boot floor. With the backrests folded down the capacity rises to 1324 litres. The wide load compartment opening makes it easier to load and unload luggage and other items.


In terms of exterior dimensions, it's 5054mm long, 2069mm wide and 1447mm tall. 

Handling and ride quality: What is the Mercedes-AMG GT 4-Door like to drive?

"While it’s not surprising that a four-wheel-drive, V8-powered AMG with 585PS accelerates quickly, the way it handles is impressive. All models feature four-wheel steering along with air suspension and - even on the wintery Scottish roads of our test - it copes very well in real-world conditions."

The front end is eager to turn in, while the steering is smooth and communicative for enthusiastic drivers. The rear-biased four-wheel-drive system, meanwhile, contributes to a sports-car-like driving experience.


One of the few negative points is the ride, which errs on the side of harsh around town, but once up to speed flows well. Indeed, when you’re not looking to mimic a Porsche 911 across country, the Mercedes-AMG GT 4-Door is a most acceptable grand tourer. Its nine-speed automatic gearbox settles on a gear quite quickly, while all the standard driver assistance tech takes the pain out of long journeys.

The AMG 4.0-litre V8 biturbo engine is already used in numerous AMG models. Its output has been enhanced for the new Mercedes-AMG GT 4-Door 4MATIC+. It delivers 639PS and maximum torque of 900Nm, which is available over a wide engine speed range from 2500 to 4500 rpm.


Acceleration from 0-62mph takes a mere 3.2 seconds. In the ‘standard’ Mercedes-AMG GT 4-Door 4MATIC+ the V8 unit provides 585PS and 800Nm maximum torque. The sprint from standstill to 62mph lasts just 3.4 seconds.

Noise levels in the Mercedes-AMG GT 4-Door depend on what mood you’re in. It will happily potter around town if you want it to, feeling as easy to drive as a diesel Mercedes-Benz E-Class. But get it out on a quick road - and put it in sport mode - and it comes alive with a beautiful engine and exhaust sound that will have you prodding the throttle whenever you get the chance. 

While the Mercedes-AMG GT 4-Door hasn’t been crash tested by Euro NCAP, we’d expect nothing less than the maximum five star crash safety rating, in line with the majority of cars Mercedes builds.

MPG and fuel costs: What does a Mercedes-AMG GT 4-Door cost to run?

"You aren’t buying any AMG if you’re worried about fuel. Officially, the GT 63 model returns 25.2mpg, and this soon drops to tens should you regularly exploit all of its performance."

During motorway cruising, though, we expect mid-20s mpg should be fairly achievable if you're light with the throttle.

Mercedes generally performs well for reliability, placing 13th out of 30 manufacturers in the latest HonestJohn.co.uk Satisfaction Index. The GT 4-Door should be fairly reliable and it's covered by Mercedes' unlimited mileage warranty for the first three years. 

A high performance AMG with a huge list price? That can only mean one thing – group 50 insurance

Despite all its performance, all models only cost £150 a year for VED. Just be aware that all models have a list price of more than £40,000 so will incur the extra £325 a year showroom tax (on top of the £150) for five years from the second time it’s taxed. 

How much should you be paying for a used Mercedes-AMG GT 4-Door?

"You won’t be getting one of these for a bargain price."

Mercedes-AMG GT models are pretty rare and the Mercedes-AMG GT 4-Door especially so. In short you aren’t getting any change out of £100,000 for a used model.

Standard equipment on the Mercedes-AMG GT 4-Door includes 20-inch AMG 5-double-spoke light- alloy wheels, Multibeam LED Intelligent headlights; parking package and 360 camera, 12.3-inch infotainment and cockpit display, creating a widescreen effect, ambient lighting with a choice of 64 colours, heated front and rear seats, Command Online infotainment system, AMG Track Pace, wireless charging, Keyless-Go Comfort package, including keyless start and hands-free access, and fully automatic opening and closing of boot lid; Burmester surround sound system and AMG Performance steering wheel in Nappa leather.


The Mercedes-AMG GT 4-Door 63 S adds the AMG Dynamic Plus package, which includes electronic rear-axle differential lock, ‘RACE’ drive mode including ‘Drift-Mode’, larger front brake discs and yellow painted AMG brake calipers; 20-inch AMG multi-spoke alloy wheels, an AMG Performance steering wheel, upholstered in Dinamica microfibre, comes as standard.


The limited edition Mercedes-AMG GT 4-Door GT 63 S Edition 1 comes as standard with Graphite Grey magno paint; 21-inch cross-spoke forged wheels with black inserts; an Aerodynamics package, including a fixed rear aerofoil in high-gloss black and optimised front apron with a front splitter; Premium Plus package, AMG Carbon Matte trim, AMG Nappa leather Magma grey seats with yellow contrast stitching, black Dinamica headlining, Memory package, Air Balance and AMG Night package.

The entry-level Mercedes-AMG GT 63 S 4MATIC+ Premium Plus starts from £155,440 and the hybrid Mercedes-AMG GT 63 S E Performance is priced from £178,705.
While the GT 4-Door is edging into supercar money and performance it's a little more practical than your typical supercar. The 2-Door Coupe steps more into supercar territory.
