The Mercedes AMG GT 63 4-door is due a mid-life refresh to help it keep pace with the likes of the Audi RS7, the new BMW M8 Gran Coupe and the recently revised Porsche Panamera. The big news is that it’ll soon be available as a GT 73e hybrid with more than 800hp.

A not-for-UK 53 version has been revealed too, giving you an idea of how the facelifted saloon will look.

New Mercedes-AMG GT 53 4-door design

Your first uncovered look at the Mercedes-AMG GT 4-door facelift comes in the form of the 53. This six-cylinder version of the car won’t be coming to the UK, but at least gives you an idea of the visual tweaks to the car.

The standard 53 is completely unchanged, though a new styling pack has been introduced to allow this six-cylinder version of the car to look like the upcoming new V8-powered versions.

Again, there’s not a lot of change here — save for some lightly tweaked air intakes upfront. The rear of the 53 gets circular exhaust exits, though expect larger and more squared-off units on the real V8 cars.

New Mercedes-AMG GT 73e hybrid performance

Mercedes has confirmed the new AMG GT 4-door will be available as a 73e hybrid for the first time. This model will keep the old car’s twin-turbo 4.0-litre V8, but also comes with a rear-mounted electric motor that can endow this already punchy car with even more performance.

How much power exactly the new GT 73e 4-door will have isn’t entirely clear, as Mercedes has yet to confirm an official power output. However, the car maker’s gone on the record to say this V8 plug-in hybrid setup is able to pump out up to 816hp, of which 204hp can come from the electric motor alone.

Little about this prototype gives away its hybrid engine, though earlier shots show one crucial difference…

Like the regular AMG GT 4-door, all of this oomph will be sent to all four wheels through a nine-speed automatic gearbox. The electric motor also has its own separate two-speed automatic gearbox, which is made up of a shorter first gear intended for stuff like standing starts, and a longer second gear that’s more suited to traveling at higher speeds on the motorway.

There’s a flap at the rear hiding the charging port

There’s no official word yet on the 73e hybrid’s electric-only driving range. However, as the battery pack is pretty small by plug-in hybrid standards at 6.1kWh, you likely won’t be able to cover much ground between charges (especially if you try and drive the car at motorway speeds using electric power alone).

An electric range of about 30 miles is to be expected at most

Use the energy stored in the battery for flat-out performance, though, and Mercedes suggests you’ll be able to accelerate from 0-62mph in under three seconds.

This new engine setup could work its way into the S Class eventually

This new high-performance hybrid system will also be fitted to the Mercedes S-Class to create a new AMG S73e – although you’ll have to wait until at least 2022 to get your hands on one of those…

New Mercedes AMG GT 63 4-door engine

The AMG GT 63 4-door will come with the same 4.0-litre twin-turbo V8 as the current car. 

The current Mercedes-AMG GT 63 4-door’s heart is a monstrous 4.0-litre twin-turbocharged V8 engine. That’ll be carried over into the new car, along with the nine-speed automatic gearbox and Mercedes’ 4MATIC four-wheel-drive system.

The engine is currently offered in two different packages – the GT 63 with 585hp, and the range-topping GT 63 S with 638hp. The new car will likely retain both options.

Mercedes AMG GT 63 4-door interior

The new car’s cabin should look very similar to the current model’s, shown here. 

The new AMG GT 63 4-door’s interior hasn’t been spotted yet, but don’t expect any radical changes. It’ll almost certainly retain the old car’s design but should feature a few software updates for the dual-screen infotainment system.

For the most part, practicality should remain about the same, too. However, because the plug-in hybrid 73e model’s battery pack will be located above the car’s rear axle, the packaging constraints means it likely won’t have the standard GT 63 4-door’s 461-litre boot capacity.

Mercedes AMG GT 63 4-door price and release date

An official launch date for the refreshed Mercedes AMG GT 4-door hasn’t been announced yet. However, a leaked image uploaded by an anonymous user to the photo-hosting website ‘imgbb’ suggests the revised super saloon will be revealed in May 2021, and go on sale a few months later in August.

Because the image only refers to the car as a general facelift, it’s also possible Mercedes could unveil the updated GT 4-door and the new range-topping 73e plug-in hybrid model in tandem with one another.

Expect pricing to be north of £150,000 for the 73e

Prices for the AMG GT 63 S models aren’t likely to change that much over the current car – expect this model to start somewhere in the region of £140,000. The 73e hybrid version will likely cost considerably more, though, to suit its place at the top of the GT 4-door pecking order.
