Behind the Wheel of the New Mercedes-Benz GLC EV
The upcoming Mercedes-Benz GLC EV signals a significant shift in the company’s electric vehicle strategy. Rather than designing completely distinct EVs, Mercedes is adopting a more integrated approach, as demonstrated by the GLC EV. This new model, set to arrive later this year, aims to seamlessly blend electric technology with the familiar GLC nameplate.
This pragmatic strategy means the GLC EV will share a similar aesthetic with the facelifted combustion-engine GLC model, slated for release next year. Mercedes aims for greater cohesion between its different powertrains to drive electric vehicle sales, according to company boss Ola Källenius. Given the existing success of the GLC, this strategy could leverage the established customer base to boost EV adoption.
This integrated approach also streamlines development and production, which is critical as Mercedes expands its electric vehicle lineup. The GLC EV is the first to leverage the new MB.EA platform, designed specifically for electric vehicles. This platform will also underpin the electric versions of the C-Class and the junior G-Class off-roader, both scheduled for a 2026 reveal.
The new GLC EV further showcases the advanced eATS 2.0 drivetrain, previewed by the Vision EQXX engineering concept in 2023. The most potent dual-motor, four-wheel-drive configuration will generate up to 483bhp, while a single-motor, rear-wheel-drive variant with 268bhp is also planned. Power will come from a 94.5kWh nickel-manganese-cobalt (NMC) battery, expected to deliver a range exceeding 404 miles. Furthermore, the vehicle will support an 800V electrical architecture, enabling charging speeds of up to 320kW, allowing for a recharge of 162 miles in approximately 10 minutes.
Efficiency is also bolstered by an innovative heat pump, which is more effective and compact than current systems. This enhancement allows for a 100-litre frunk in addition to the 560-litre rear boot, offering more luggage capacity than the current ICE GLC models offer. Mercedes has also developed a sophisticated brake energy recuperation system known as One Box, where the brake pedal is decoupled from the physical braking system, relying on computers to manage the balance between regenerative and physical disc braking. This system is a significant advantage.
Dominik Voogdt, head of overall vehicle engineering for the GLC EV, describes the new braking system as a “game-changer” for overall efficiency.
Driving in the Arctic
My initial driving experience with the GLC EV took place on the Galtispuoda mountain pass, located just outside Arjeplog in Sweden’s Arctic north. This challenging, snow-covered road provides a rigorous test for a car’s handling. The route featured steep inclines, treacherous descents, along with a mixture of fast bends and sharp hairpin turns, which all tested the GLC EV’s capabilities in the variable conditions. The surfaces shifted unpredictably between compacted snow and sheer ice.
Although the prototype’s interior was heavily disguised, the driving position and ergonomics remained familiar, with typical Mercedes refinement. The longer wheelbase, a result of the MB.EA platform, provides increased cabin space, particularly for rear passengers. However, the focus was to experience the driving dynamics.
Despite the challenging conditions, the new eATS 2.0 drivetrain delivered impressive performance, particularly with traction and swift acceleration on the straighter sections. The stability-control system operated smoothly and efficiently, maintaining a controlled progress on the icy surface. Voogdt confirmed that changes to the vehicle operating system have reduced the amount of CPU networking to provide faster and more seamless control of power to each of the wheels.
The steering, normally light, was precise and provided excellent feedback, enhancing driver confidence. This was further aided by the rear-wheel steering function, which was tuned by the same engineers who developed similar systems for Mercedes-AMG models, with a rear steer of 4.5 degrees on the prototype. The overall agility of the GLC EV was surprising given its size and weight.
Driving carefully through the winding sections, it was clear the GLC EV was responsive and eager to change direction. Even without specialized spiked tires, the regular winter tires provided remarkable grip. The air suspension, with adjustable ride height, effectively controlled body movement. The new brakes also impressed, with the majority of the braking force handled by regen, even during hard braking. The amount of regeneration is also a key factor.
The GLC EV is expected to be produced at Mercedes plants in Bremen, Germany, and Beijing, China, along with the possibility of additional output in Tuscaloosa, US, depending on tariff considerations.
