New Mercedes GLC Prototype Review: Promising All-Electric SUV with EQ Technology

Mercedes’ all-electric future is taking shape, and its best-selling model, the GLC, is slated to go fully electric in 2025. We had an exclusive opportunity to take an early drive in a prototype GLC equipped with EQ Technology, the BEV (Battery Electric Vehicle) version of the popular SUV. Based on Mercedes’ EV-specific MB.EA platform, this new model promises strong performance, impressive range, and rapid charging capabilities.
While Mercedes remains relatively tight-lipped about specific details, the prototype drive offered a compelling glimpse of what’s to come. The all-electric GLC will be available in both rear-wheel-drive and all-wheel-drive (4Matic) configurations. The 4Matic version leverages a front motor with de-coupling technology to distribute power to all four wheels. The rear motor, meanwhile, features a two-speed gearbox, enhancing both performance and efficiency. Drive distribution in the 4Matic system is managed based on road conditions and driver-selected modes. In Comfort mode, the system defaults to rear-wheel drive, while Sport mode offers a 33:66 front-to-rear split, and Terrain mode provides a 50:50 split.

The prototype we drove was the 4Matic model, utilizing two motors for a combined output of approximately 360kW (482 bhp). This setup delivers brisk acceleration, even when tested on snow with winter tires in the extreme conditions of northern Sweden, where Mercedes-Benz engineers were busy putting the vehicle through its paces.
One of the key considerations for electric vehicles is battery performance in cold weather. The GLC prototype addresses this with efficient thermal management, including an air-side heat pump, which also contributes to the vehicle’s high charging potential. The GLC boasts 800V technology, enabling rapid charging at speeds up to 320kW. This means that just 10 minutes of charging can provide approximately 160 miles of driving range. The battery pack has a capacity of 94.5kWh, projecting a range of around 400 miles, although smaller battery options will also be available.
This top-tier battery, similar to the one in the upcoming CLA BEV, uses anodes with silicon oxide blended to graphite. This innovative design results in greater energy density and helps to reduce weight, further boosting efficiency and performance.
Behind the wheel, the GLC offers a sense of briskness. However, it’s not only the performance we were impressed with. The steering offers a degree of feedback, and the brake pedal, often a weak point in EVs, feels natural and progressive. This is thanks to Mercedes’ new braking system, which integrates traditional braking functions into a compact module. It smartly juggles stopping power through recuperation and friction brakes for effective stopping. The optional air suspension effectively manages the GLC’s mass. Simultaneously, the rear-wheel steering enhances its maneuverability at lower speeds and improves stability at higher speeds.
While our drive was limited, and the environment was extreme, the GLC demonstrates real promise. Interior space is also generous. Although the GLC has a stretched wheelbase, its dimensions remain comparable, offering increased cabin area. Rear passengers, in particular, benefit from added legroom. The boot space will likely match that of the combustion-engine-powered GLC, while the BEV model offers around 100 liters of under-bonnet storage. Moreover, the GLC will be able to tow up to 2,400kg for heavier loads.
