Mercedes-Benz Tests the New Electric GLC Beyond the Arctic Circle

Mercedes-Benz is putting its new all-electric GLC with EQ Technology through rigorous testing in extreme winter conditions. As the successor to the EQC, this model introduces significant technological advancements, featuring an 800-volt architecture, next-generation batteries, and an entirely new braking system.

Advanced Engineering and Cutting-Edge Features
The GLC electric version maintains a strong design resemblance to its internal combustion counterpart while being far more technologically advanced than the outgoing EQC. The vehicle is equipped with silicon carbide-based inverters, a dual-speed rear electric motor, and a fully integrated braking system, combining the brake booster, master cylinder, and ESP module into a single unit.

One of the most innovative upgrades is its heat pump, which draws energy from three sources—waste heat from the battery, electric motors, and ambient air. This system warms the cabin in winter, cools it in summer, and preconditions the battery before fast charging for maximum efficiency.

Mercedes-Benz will offer multiple battery options, with the most advanced variants featuring graphite and silicon oxide anodes, enabling compatibility with 320 kW ultra-fast charging stations.

Extreme Cold Testing in Northern Sweden
The new GLC electric SUV is currently undergoing extensive testing in Arjeplog, Sweden, beyond the Arctic Circle. Engineers are conducting over 500 standard and 100 specialized tests, focusing heavily on electronic performance and charging efficiency in freezing conditions. Key objectives include evaluating real-world range at low temperatures and optimizing regenerative braking.

In addition to powertrain testing, Mercedes-Benz is fine-tuning the steering system, stability control, and all-wheel-drive technology. The dual-motor powertrain features individual torque distribution, with the front motor capable of automatic deactivation to conserve energy when needed.
