Mercedes-Benz has put its upcoming all-electric GLC through extreme winter testing in Sweden, ensuring it meets real-world demands for safety, efficiency and performance in sub-zero conditions.
Camouflaged prototypes tackled snow-covered roads and icy surfaces, refining their systems in temperatures as low as -25°C.
Christoph Starzynski, Vice President of Overall Vehicle Development & Integration at Mercedes-Benz Group AG, said, "Our new electric GLC is a car without compromises – and we test it just as uncompromisingly. During winter testing in Sweden, our new, all-electric GLC demonstrated its reliability and robustness even under extreme conditions."
Drivetrain upgrades
The electric GLC features an updated 4Matic all-wheel-drive system with a Disconnect Unit (DCU) that can disengage the front axle when not needed, improving efficiency. Real-time torque distribution helps optimise grip on slippery surfaces, ensuring the SUV remains stable even in challenging conditions.
A newly developed rear-axle electric drive unit, engineered in-house, benefits from silicon carbide inverters for improved efficiency. The dual-motor setup enhances performance while maintaining energy conservation, allowing for longer driving ranges even in cold temperatures.
Smarter braking
Mercedes-Benz has introduced a new braking system that integrates the brake booster, master cylinder and ESP control into a compact module, refining both brake feel and energy recuperation.
The system seamlessly blends regenerative and friction braking, recovering energy that would otherwise be lost to further extend range.
A hydraulic fallback ensures braking reliability, maintaining safety standards even in the event of an electronic failure.
Faster charging and extended range
Built on an 800V electrical architecture, the electric GLC supports rapid DC charging at rates exceeding 320 kW - significantly faster than its EQC predecessor.
Mercedes-Benz will offer multiple battery options, with the top-tier variant featuring high-energy-density cells that improve both range and efficiency.
An integrated heat pump comes as standard, using waste heat from the battery, electric motors and ambient air to warm the cabin efficiently.
Compared to traditional electric heaters, this system reduces energy consumption while maintaining passenger comfort. It also optimises the battery temperature for faster charging in cold weather.
Testing beyond the Arctic Circle
Mercedes-Benz conducts rigorous winter testing at its Arjeplog facility in Sweden, where vehicles navigate snow-covered tracks, icy inclines and frozen lakes.
Over 500 individual tests were conducted on the electric GLC, with a focus on eDrive performance, charging reliability and traction control.
Beyond winter trials, testing continues in extreme heat conditions in Arizona and South Africa to ensure the vehicle delivers consistent performance in all climates.
A new era for the GLC
As part of Mercedes-Benz’s strategy to integrate EVs more closely with its combustion models, the new GLC ditches standalone EQ branding in favour of the "with EQ Technology" suffix.
With refined aerodynamics, a focus on practicality and enhanced real-world usability, it aims to challenge the Tesla Model Y and other premium electric SUVs.
Full technical specifications will be revealed closer to launch, but early indicators suggest the electric GLC is well-positioned to become a serious player in the premium EV market.
