 Ultra Geländewagen: Within Mercedes-Benz engineering circles the future model W463, i.e. the EQG electric off-road vehicle has already earned its reputation as the best in its class and is affectionately called using the German word which literally means off-road vehicle and which was the basis for the commercial definition of Class G.

Mercedes EQG, it will really be the ultra electric Geländewagen

But it is equally easy to explain the value of the term Ultra, given that the transition to 100% electric propulsion will mean entering a world of performance never before offered by a 4x4.

EQG, for example, will use four single engines for traction and will have the ability to make turns on itself like tanks or, on a smaller scale, Bobcat excavators.

    In its final version, which will start to be sold in 2024, the EQG will be an "unrivaled combination of luxury and off-road capability in the field of electric vehicles - underlines Emmerich Schiller, CEO of Mercedes-Benz G GmbH and head of the off-road product division of Mercedes- Benz AG - From the outset, it was decided that the electric G-Class should be at least as capable as the internal combustion engine model both on and off the road. We didn't want to compromise on capabilities."

    Built on a modified steel ladder frame chassis - the same as the internal combustion models - the EQG will be produced at longtime partner Magna Steyr in Graz, Austria retaining the same distinctive boxy exterior styling as the other existing G-Class models .

At the heart of the technical development of the EQG is a new propulsion system consisting of four electric motors, one for each wheel.

Unique in Mercedes' current EQ model range with this architecture, it draws on the experience of the SLS E-Cell produced by the company's AMG division in 2013.

    Today the four-engine layout is also used - reports Autocar magazine - by the US start-up Rivian for the R1 SUV and the pick-up and will be able to provide the EQG with what Schiller describes as "an unparalleled combination of performance off-road and refined on-road qualities".

Schiller points out that the system is also very expensive, but offers unique performance.

With two electric motors you need differential locks, which means a combination of electronic and mechanical systems.

"And with three engines, one front and two on the rear axle - he says - you don't get the maximum performance in off-road conditions".

Inspired by the concept car seen at the 2021 IAA Munich, the EQG features low-mounted front electric motors on each side within the

inside of the axle while the rear ones are integrated more towards the center in a de Dion style axle specially designed for this model.

The electric units provide individual drive to each wheel through a 2-speed mechanical gearbox, offering both high and low range ratios.

    Along with the traditional on-road driving modes – Eco, Comfort and Sport, EQG will offer the three off-road specific modes Trail, Rock and Sand.

And there will be an additional Creeper mode to set a predetermined speed on more challenging off-road sections.

Naturally, the electronic management systems of the electric motors are able to simulate the three locking differentials (one on each axle and one in the transfer case) of the petrol G-Class.

    Also provided is the G-Turn function, activated by a button mounted on the dashboard.

When engaged the motors on one side turn the wheels forward and those on the opposite side reverse, allowing the EQG to perform spectacular 360 degree turns without moving, like tanks.

    The Ultra Geländewagen will use a lithium-ion battery, with an energy capacity of around 100 kWh, sharing cell technology with that provided by the EQXX concept.

To protect the battery under extreme off-road driving conditions, it is housed within a rugged, sealed steel casing that allows the EQG to wade through deep water.
