What is it?

The Mercedes-Benz G-Class has long been known for its distinctive boxy design and rugged off-road capability. Now, with the introduction of the G580 with EQ Technology, Mercedes has given its iconic SUV an all-electric powertrain. This version retains much of what makes the G-Class unique but introduces an electric drivetrain with four motors, significant off-road enhancements, and a high-capacity battery.

With a starting price of £180,000, the G-Class Electric is positioned as a luxury off-roader, competing against other high-end electric SUVs such as the BMW iX, Volvo EX90, Lotus Eletre, and the upcoming electric Range Rover​

Design and Styling

Visually, the electric G-Class remains largely unchanged from its combustion-engine counterparts. The boxy shape, upright stance, and signature round headlights all remain, maintaining the SUV’s familiar appearance. However, there are a few subtle design tweaks to improve aerodynamics and efficiency:

A raised bonnet and a lip above the windscreen to reduce drag.

A larger cabin vent for better air pressure equalization when closing the doors.

A charging cable storage box mounted on the rear door, replacing the traditional spare wheel (though buyers can opt for a spare wheel instead).

Despite these modifications, the G-Class Electric still looks and feels like a G-Class, ensuring it appeals to loyal fans of the model​.

Interior and Technology

Inside, the G-Class Electric follows the same luxury-focused approach as the standard G-Class, with high-quality materials, premium finishes, and Mercedes’ MBUX infotainment system. The cabin includes:

Twin 12.3-inch screens, one for the driver’s display and the other for infotainment.

Physical buttons for heating and climate controls, making adjustments easier while driving.

Haptic touch controls on the steering wheel, which can be sensitive and difficult to use precisely.

Burmester sound system, offering a high-end audio experience.

Seating remains upright and commanding, though rear legroom is not as generous as one might expect, considering the G-Class’ large footprint. The 555-litre boot is slightly smaller than in combustion-powered versions and less than some rivals, such as the Volvo EX90 and Lotus Eletre​.

How Does It Drive?

The G580 is powered by four electric motors, one for each wheel, delivering 579bhp and 859lb ft of torque. This setup enables:

0-62mph in 4.7 seconds, making it nearly as quick as the AMG G63.

A top speed of 112mph, reflecting its focus on torque and off-road capability rather than outright speed.

Regenerative braking with adjustable strength, controlled via steering wheel paddles​.

One of the standout features is Mercedes’ artificial engine noise system, G-Roar, designed to mimic the sound of a petrol V8. While some may find it entertaining, it can be turned off for a quieter ride​.

On the road, the G-Class Electric feels heavy, which is expected given its 3,209kg kerb weight. The coil spring suspension and adaptive dampers provide a comfortable ride, but there is noticeable body movement over uneven surfaces. Steering is slower and less direct than in other high-end electric SUVs, making it feel more like a traditional off-roader than a dynamic road vehicle​

Off-Road Capability

Mercedes claims that the G580 is even more capable off-road than its combustion-powered siblings. Key enhancements include:

Independent front suspension and a solid rear axle, designed for extreme terrain.

850mm wading depth, significantly higher than that of previous G-Class models.

G-Turn function, allowing the vehicle to rotate in place by spinning the wheels in opposite directions.

G-Steer system, which assists in tight turns by selectively braking the inside rear wheel.

The four-motor system provides precise control over each wheel, making it easier to navigate uneven terrain and deliver instant torque to the wheels with the most traction​

Range, Charging, and Efficiency

The G-Class Electric is equipped with a 116kWh battery, providing an official WLTP range of 294 miles. In real-world conditions, efficiency is expected to be lower, with estimates closer to 2 miles per kWh, making it less efficient than many other electric SUVs​

Charging details:

Max DC charging speed: 200kW (10-80% charge in 32 minutes).

AC charging: 11kW, taking nearly 12 hours for a full charge​

While Mercedes highlights that the G-Class Electric can complete 14 laps of the Schökl off-road test track before running out of battery (compared to six laps in the petrol G63 before refueling), the overall efficiency remains one of its weak points​

Practicality

While the G-Class Electric maintains a luxurious and spacious cabin, practicality is somewhat compromised:

Boot space is 555 litres, smaller than combustion-powered versions and some rivals.

Maximum payload is only 415kg, limiting its utility as a workhorse.

No towbar option, removing one of the key capabilities often expected from large SUVs.

Rear seats fold down, but a large ridge in the boot floor makes loading larger items more difficult​

For urban driving, its large dimensions and high weight make it less manoeuvrable than smaller electric SUVs, and wind noise is noticeable at motorway speeds, despite the quiet drivetrain​

Verdict

The Mercedes G-Class Electric delivers on its promise of being a fully capable electric off-roader, retaining the rugged character and luxury appeal of the G-Class while incorporating modern EV technology. However, it comes with notable drawbacks, including high weight, limited efficiency, and a high price tag starting at £180,000.

Pros:

✔ Retains the classic G-Class design and off-road capability.

✔ Four-motor system offers excellent traction and control.

✔ Luxurious interior with high-quality materials and technology.

Cons:

✘ Very heavy, affecting handling and efficiency.

✘ High price compared to rival electric SUVs.

✘ Limited payload and no towbar option reduce practicality.

For those looking for a high-end, all-terrain electric SUV, the G-Class Electric is an impressive, if expensive, option. However, those prioritising range, efficiency, and on-road refinement may find better alternatives in models like the BMW iX, Volvo EX90, or upcoming electric Range Rover
