The Mercedes-Benz GLC is the brand’s top-selling SUV, with an all-electric version set to join the lineup soon. The forthcoming new electric GLC incorporates what M-B says is the latest technology, delivering exceptional range, efficiency, and charging speeds.
Extreme Winter Testing
Mercedes-Benz has recently tested the electric GLC in Swedish Arctic conditions. Christoph Starzynski, Vice President of Overall Vehicle Development, emphasized the vehicle’s robustness and quality, highlighting its innovation and ability to perform under all conditions.

Advanced All-Wheel Drive & Handling
The 4MATIC all-wheel-drive system will likely ensure good traction and handling on winter roads. A Disconnect Unit (DCU) allows the front axle drive to engage or disengage as needed, enhancing efficiency. Sensors detect wheel spin, and torque is distributed to maintain stability. Electric motors operate independently, ensuring optimal power delivery.

A new braking system integrates the brake booster, master cylinder, and ESP control into a compact module, enhancing pedal feedback and energy recuperation. This increases range by recycling braking energy. If an error occurs, the system switches to a hydraulic fallback mode, ensuring safety.

Innovative Battery & Charging Technology
The all-electric GLC features new battery systems, with an 800-volt architecture and high-performance drive units. A two-speed transmission on the primary rear axle is said to enhance efficiency.
Different battery versions will be available, with the top-tier variant supporting sustained DC charging over 320 kW. The silicon oxide-blended graphite anodes increase energy density, providing longer driving ranges and lighter batteries for improved efficiency. Range and outputs are still TBA.

A heat pump optimises temperature control, using waste heat from the electric drive unit, battery, and ambient air. This allows efficient cabin heating with minimal power consumption, says Merc, ensuring comfort even in extreme cold. Additionally, the heat pump helps maintain optimal battery temperature during fast charging, improving performance.
Mercedes-Benz Testing Standards
Mercedes-Benz’s Arjeplog testing center near the Arctic Circle conducts over 500 tests for each new model, including 100+ electric vehicle-specific trials. These focus on cold-start performance, battery range in real-world conditions, charging cable handling, and energy recuperation strategies. Specialised tests also refine driving dynamics and ESP calibration for optimal safety.

The testing site offers various charging options, from household outlets to ultra-fast chargers, ensuring the GLC meets all customer charging needs. Beyond winter trials, Mercedes-Benz also tests vehicles in extreme heat conditions, such as in Arizona and South Africa, where temperatures reach 50°C.
