Mercedes-Benz AMG GT 4-Door Review 2024

The Mercedes AMG GT 4-Door adds some family-friendly practicality and limo-like luxury to the otherwise uncomfortable and cramped world of supercars. But is it a better choice than the likes of the Porsche Panamera or another German contender, the Audi RS7 Sportback? Read our Mercedes AMG GT 4-Door review to find out.

Despite the supercar connotations, the Mercedes AMG GT 4-Door has more in common with the Mercedes CLS than the two-seater Mercedes AMG GT, with a similar swoopy exterior profile that should provide enough interior space and storage for four adults to travel in comfort.

The boot capacity ranges from 461 litres to a modest 335 litres depending on the powertrain, while passengers sitting in the rear get an Audi A8-style touchpad screen to control heating, lighting and seating adjustments.

At launch, the Mercedes AMG GT 4-Door was available with a choice of three engine options: a 3.0-litre V6 with 435PS in the Mercedes AMG GT 4-Door 53, and two 4.0-litre twin-turbo V8s in the Mercedes AMG GT 4-Door 63 and Mercedes AMG GT 4-Door 63 S, offering 585PS and 639PS respectively.

The range has since been rationalised to just two versions – the Mercedes AMG GT 4-Door 63 S and the Mercedes AMG GT 4-Door 63 S E Performance, which adds plug-in hybrid power to the V8 engine to give a maximum output of 843PS.

That’s enough to launch it from 0-62mph in 2.9 seconds and on to a top speed of 196mph, making it a genuine four-door supercar.

The interior uses the same panoramic design as the Mercedes E-Class, with a wide windscreen and sweeping dashboard that’s dominated by a pair of 12.3-inch HD screens.

The digital instrument binnacle can be configured with different themes – classic, sport and supersport – allowing the driver to add details on torque, traction, engine data and g-force. Supersport mode also features an F1-style gearshift light indicator for track driving.

Depending on the engine, there are up to six drive programmes to choose: slippery, comfort, sport,  sport+, race and individual.

Selectable via the gearshift paddles, the settings sharpen the handling, gearbox and throttle responses. The suspension and traction control can also be tailored to match track requirements.

Many modern supercars manage to combine a docile nature in normal driving with mind-bending performance in the right conditions, but the Mercedes AMG GT 4-Door does so in a remarkable fashion.

Partly this is down to the fact it feels like a relatively normal car from behind the wheel, albeit an expensive coupe. The driving position is comfortable, it is easy to see out of and you can fit more than one passenger in it, unlike most other high-performance cars.

However, the Mercedes AMG GT 4-Door 63 S versions – in particular the Mercedes AMG GT 4-Door 63 S E Performance – offer genuinely incredible performance, with strong acceleration available from almost any speed and revs, all accompanied by a raucous V8 sound from the exhaust.

Despite its size and weight, everything is kept under control by strong brakes and Mercedes’ 4MATIC four-wheel-drive system.

With a hefty price tag and running costs that are likely to be equally alarming, the Mercedes-AMG GT 4-Door is not for everyone.

But for those with the budget and the need to carry up to three passengers in comfort and significant speed, it is an impressive car with few genuine rivals.

Producing a car of this size that has handling to match its performance while offering good ride comfort is a significant challenge.

Although the Mercedes AMG GT 4-Door is not perfect, it does an impressive job of achieving a reasonable balance.

Despite its size and bulk, the Mercedes AMG GT 4-Door is impressively agile. This is in part thanks to the four-wheel-drive, but also the four-wheel-steer system, which turns the rear wheels a few degrees in certain conditions to help the car rotate.

While it is never going to be as nimble as the Mercedes AMG GT Coupe, it offers the driver an engaging experience that is a great deal of fun in the right circumstances.

Four-wheel-drive traction means it is easier to exploit the available performance, and there is even a Drift mode that allows the driver to disengage drive to the front wheels if so desired.

Similarly, the Mercedes AMG GT 4-Door is not as soft or supple in terms of ride quality as the luxury-focused Mercedes S-Class for example, not least because it rides on very large alloy wheels with low-profile performance tyres.

However, select the appropriate drive mode and the suspension is softened up, which means it is capable of riding with relative smoothness.

Certain road imperfections, such as long undulations at speed and broken urban streets, can cause a little discomfort.

But it strikes a good compromise between comfort and handling in most conditions.

Given that the least powerful of the current Mercedes AMG GT 4-Door range offers a sizeable 639PS, impressive performance is never in doubt.

With twin turbochargers pushing air into the 4.0-litre V8 engine and a slick automatic gearbox seamlessly switching gears, there is always strong acceleration available, accompanied by a thrilling exhaust note – particularly in the more aggressive drive modes.

The Mercedes-AMG GT 4-Door 63 S can dispatch the 0-62mph sprint in only 3.2 seconds and run on to 196mph, which is genuine supercar pace.

The Mercedes-AMG GT 4-Door 63 S E Performance uses its hybrid powertrain to boost the total output to a remarkable 843PS, making it one of the most powerful new cars on the market.

In some respects, the fact that it is only 0.3 seconds quicker to 62mph is almost disappointing, but this is more down to the challenge of laying all that power on to the road, even with four-wheel-drive.

The top speed is also 196mph, but without electronic restriction it would top 200mph.

It’s not just the outright performance that is impressive, but the manner in which it is delivered. The V8 engine is full of character, so much so that it is hard for the driver to exercise restraint.

Even small blips of the accelerator produce notable acceleration, and the range of sound that it can produce is addictive.

It may even be too extreme for some drivers with the exhaust in its loudest setting, but the combination of four-door practicality with a hot-rod engine holds great appeal.

The Mercedes AMG GT 4-Door has not been safety tested by Euro NCAP, but there are many factors that suggest it is an impressively safe vehicle.

For starters, the platform on which the Mercedes AMG GT 4-Door is based is closely related to the Mercedes E-Class and Mercedes CLS, which received a five-star rating when it was tested in 2016.

In addition, the structure is actually stiffened compared with these cars, so it should provide a very robust bodyshell.

Further to that, it is packed with standard safety features, including active lane keeping assist, blind spot assist and active brake assist, as well as the option of a driving assistance package that adds even more features.

The Mercedes AMG GT 4-Door 63 S offers a towing capacity of 750kg unbraked and 2,100kg braked.

Figures are not provided for the Mercedes AMG GT 4-Door 63 S E Performance.

The main reason anyone would choose this Mercedes AMG GT 4-Door over the coupe version is the additional practicality it offers. So whether it actually delivers on this front is likely to be an important factor.

For front-seat occupants, it’s all good news. There is plenty of legroom, headroom is generous and elbow room is decent, too, even if the wide centre console can make larger drivers feel a little hemmed in.

In the rear, legroom and elbow room are also good.

However, the steep slope of the roofline means that headroom is not as abundant as in the front, so taller adults may find it uncomfortable on longer journeys.

Most versions of the Mercedes AMG GT 4-Door are fitted with a three-seat rear bench, but the Mercedes AMG GT 4-Door 63 S E Performance has two individual rear seats.

Boot space varies depending on the model. Most versions offer a useful 456 litres, but in the Mercedes AMG GT 4-Door 63 S E Performance this is reduced to 335 litres, due to the hybrid powertrain, which is somewhat disappointing for a car of this size.

Buyers expect high standards from the German brand in terms of quality, especially from a car with this kind of price tag, and in most areas the Mercedes AMG GT 4-Door delivers.

The majority of the interior is carried across from the Mercedes E-Class, but this is no bad thing.

The large twin-screen display dominates the cabin, and although many of the switches and controls feel familiar, it still has a quality feel. Those same switches are solid to the touch.

There is also a significant amount of personalisation available, although the standard Nappa leather feels of good quality.

There’s the option of multi-tone seats which add to the luxurious ambience, while the standard carbon-fibre piano lacquer trim can be substituted for open pore wood, which has a classier feel.

As standard, the Mercedes AMG GT 4-Door is fitted with a comprehensive infotainment system with twin 12.3-inch screens, controllable by a central touchpad, a second touchpad on the steering wheel, voice control or the touchscreen itself, giving plenty of choice for the driver and passenger.

It also comes with augmented reality for navigation, which is a useful feature and makes it easy for the driver to follow the guidance.

A high-specification Burmester surround sound audio system is also standard, delivering exceptional sound quality, while Apple CarPlay and Android Auto are also compatible, allowing easy connection to a smartphone.

Controlling the system is straightforward, with clear menus and sharp graphics adding to the feeling of quality.

There is even the option to add a touchscreen control for rear passengers, adding to the car’s credentials as a genuine four-door luxury vehicle.

As far as new models are concerned, deep pockets are required whichever version of the Mercedes AMG GT 4-Door you choose.

At the time of writing, the Mercedes AMG GT 4-Door 63 S starts at £156,000, while the Mercedes AMG GT 4-Door S E Performance version is £179,000.

Although not offering quite as much performance, the Porsche Panamera Turbo E-Hybrid starts at £141,000, while the BMW M8 Competition Gran Coupe is £139,000. So the Mercedes requires a significantly larger investment.

As for used examples, the earliest 2019 cars are around £65,000 and upwards with reasonable mileages.

This obviously constitutes a significant reduction on the new list price.

Anyone considering a car such as this has to accept that running costs will be high, although given the performance available, fuel consumption is not as frightening as it could be.

Thanks to its hybrid drivetrain – although designed to boost performance rather than economy – the more powerful and faster Mercedes AMG GT 4-Door 63 S E Performance has an official combined figure of 32.5mpg, as well as an electric range of 7.45 miles.

That may not be enough for long journeys, but it’s suitable for short urban trips. In contrast, the Mercedes AMG GT 4-Door 63 S has an official combined figure of just 21.6mpg, so expect real-world figures to drop into the teens.

Unsurprisingly, insurance costs will also be high. All versions are rated group 50 for insurance.

The Mercedes AMG GT 4-Door 63 S is fitted with 4MATIC four-wheel-drive and four-wheel-steering, cruise control, keyless go, LED headlights, a panoramic roof, 21-inch alloy wheels, memory package, climate front seats, head up display and Burmester audio system.

The Mercedes-AMG GT 4-Door 63 S E Performance adds carbon ceramic brakes, pre-entry climate control and two individual rear seats.
