THE GLC has long reigned as the most popular SUV model from Mercedes-Benz and, in 2024, it was the brand's best-selling series.

Now, there is a new all-electric GLC to enhance the lineup.

Moving forward, there will be a diverse array of powertrains to cater to all customer needs.

Engineered as a battery electric vehicle (BEV), the new all-electric GLC incorporates the latest technology from the esteemed brand.

In terms of performance, range, efficiency and charging speed, the electric GLC sets new benchmarks.

Heavily camouflaged prototypes of the electric GLC recently embarked on rigorous winter trials in the polar regions of Sweden.

During harsh winter testing in Swedish Arjeplog, the new Mercedes-Benz GLC showcased its exceptional ride and handling qualities, as well as superior traction on winter roads thanks to 4MATIC.

The all-wheel-drive models feature a powerful front-axle drive unit, which can be swiftly engaged or disengaged using a Disconnect Unit (DCU) when needed.

To ensure optimal traction and driving stability on snow and ice, sensors detect spinning wheels and distribute torque according to the operating strategy.

Since both electric motors are controlled independently, the driving force remains optimally maintained.

In the new, all-electric GLC, the entirely Mercedes-Benz-developed electric drive unit on the rear axle sets new benchmarks.

In addition to the sensitive and responsive all-wheel drive and precise steering, the new system also impresses on the Swedish tracks.

With its cutting-edge battery and drive technologies, the all-electric GLC achieves an impressive range even in very cold conditions.

Among its technological marvels are the 800-volt architecture and sophisticated drive units featuring a two-speed transmission on the primary rear axle drive unit. This 800-volt system optimises both efficiency and performance, substantially reducing charging times.

Various iterations of high-voltage batteries will be available for the GLC.

The premier battery variant will support DC charging with sustained rates of more than 320 kW. Beyond their usable energy capacity, these batteries also differ in cell chemistry. The top-tier battery cells use anodes with silicon oxide blended into graphite, achieving exceptionally high gravimetric energy density. This allows for longer driving ranges and lighter batteries, enhancing vehicle efficiency and performance. Consequently, the GLC benefit from better fuel efficiency and greater practicality.

Even operation in the deepest wintry conditions, the all-electric GLC has exceptional temperature comfort and the forthcoming model will be equipped as standard with an air-side heat pump.

When it comes to heating the interior, this system utilises approximately one-third of the electrical energy that a comparable electric heater would consume to achieve the same output under identical conditions.

For decades, Mercedes-Benz has subjected each new model to the most extreme conditions near the Arctic Circle. As a result, the vehicles endure temperatures as low as minus 25 degrees Celsius as well as navigating snow-laden roads and traversing the sheer ice of frozen lakes.

To facilitate this, the company operates a dedicated testing centre in Arjeplog, close to the Arctic Circle in Sweden.

Beyond road testing in the far north, the centre features meticulously designed test tracks. These include challenging hill climbs with gradients up to 20 per cent, test tracks with varying friction coefficients, handling courses and circular tracks on the nearly bare ice of the frozen lake, all of which impose significant demands on the drive and control systems.

New challenges for an electric vehicle include the power output of the electric motor during a cold start with a chilled battery, range in customer driving conditions, handling of charging cables, preconditioning and the operating strategy including recuperation. Additionally, the specific tuning of driving dynamics and the ESP system is crucial.

To test various customer requirements and charging profiles, the Arjeplog test centre offers the full range of charging options: from simple household outlets to wall boxes and fast-charging stations.

Systematic overall vehicle validation is a comprehensive measure in the development process of every Mercedes-Benz series, ensuring high-quality standards. In addition to winter testing, summer testing with intense sunlight and temperatures up to 50 degrees Celsius is also conducted, for example in Arizona and South Africa.
