New Mercedes-AMG G-Class


It is nigh on impossible to summarise the Mercedes-AMG G 63.

Although the vehicle's history dates back to the 1970s when it was mostly designed for military use, the passenger G-Class, also known as the G-Wagen, first appeared almost four decades ago. It has remained virtually unchanged until 2018 when the second generation model was launched.

Engine and Performance

There are different driving modes to choose from, with Sport and Sport+ really livening up the handling, but the Comfort setting also delivers rewarding performance with thrilling acceleration and all the power you could possibly wish for. Admittedly, it is no hatchback, but they can not tow a 3.5-tonne horse-box whilst still somehow managing the 0 to 62mph sprint in just 4.5 seconds.

The official combined fuel economy figure for the AMG G 63 is 21.4mpg, although that is when the vehicle is driven relatively conservatively. When driven in Sport or Sport+ driving modes, you will notice a drop in this figure.

Mercedes has replaced the outgoing 5.5-litre V8 engine with a brand new AMG 4.0-litre V8 biturbo petrol unit that generates 577bhp and delivers a maximum torque of 627lb ft.

And with that mighty engine powering the AMG G 63, the performance stats cannot fail to impress with that blisteringly quick 0 to 62mph sprint time and a top speed of 137mph.

Our car featured an additional AMG Drivers Package that increased the maximum speed to an electronically-limited 149mph.

If it is a quiet, unassuming existence you are seeking, then the G-Wagen is not the car for you. It is big, bold and brutal with go-anywhere off-road capabilities.

Despite resembling a giant container on wheels with a high centre of gravity, the G-Wagen drives really well.

Admittedly, tight bends need to be given a degree of respect, but the rear-biased all-wheel drive system keeps the car well planted. And when the open road presents itself, the driver can take complete control of the gear changes by switching across to Manual and using the steering wheel mounted paddles.

Design and Practicality

The latest G-Wagen has had a bit of a growth spurt and also shed some weight. This means there is more space for occupants within the car, the performance stats have improved, and it is even more economical to run.

While the exterior looks have been updated slightly, the five-door vehicle still maintains all its traditional iconic design cues such as the box-like silhouette, a full-sized spare wheel on the rear door with an aluminium cover, external door hinges, round headlamps, and the rippled bonnet.

Comfort levels within the vehicle are deceptively good, and the ride and handling have certainly been refined in the latest model.

Equipment and Technology

Techno treats are plentiful with Mercedes’ COMAND Online navigation system, a 12.3-inch media display and 12.3-inch instrument display where the likes of smartphone integration via Apple CarPlay or Android Auto can be found.

A 15-speaker Burmester sound system is guaranteed to drown out any road surface or engine noise and when you reach your destination in the dark, you open the door to see the giant Mercedes three-pointed star lighting up the pavement; it is more like a puddle floodlight than a puddle lamp.

There is also the finest Nappa leather upholstery and powered seats with memory settings, 64-colour ambient lighting, an electric sliding sunroof, black flamed open-pore ash wood trim, a heated steering wheel, and heated rear seats.

Factor in a raft of innovative safety features and the new AMG G 63 is quite a unique piece of kit.


The Mercedes-AMG G 63 is a popular choice for drivers as it is 2.5-tonnes of pure muscle that has legendary off-roading ability, perfect for a whole range of uses.

Move inside, and there is a level of elegance and charm within the vehicle that belies its rugged exterior styling, along with a wealth of on-board technology.

It looks truly distinctive, has all the latest creature comforts and is possibly one of the toughest vehicles on our planet, making the AMG G 63 a perfect all-rounder.
