Electric Mercedes GLC-Class gets 2-speed gearbox, multiple battery options

  • A fully electric Mercedes-Benz GLC-Class with EQ Technology arrives in 2026
  • The electric compact crossover will be among the first models on the MB.EA dedicated EV platform
  • A related C-Class with EQ Technology is also due next year

Mercedes-Benz plans to launch an electric GLC-Class next year, alongside a related electric C-Class.

The compact duo will carry the “with EQ Technology” designation, marking them as the electric versions of the C-Class and GLC-Class families—similar to the electric version of the G-Class. They will also be the first models built on Mercedes’ MB.EA dedicated EV platform.

This platform is distinct from the MMA platform, which Mercedes is launching this year in its next-generation CLA-Class. On Tuesday, the automaker confirmed that the MB.EA platform will feature a 2-speed transmission at the rear axle, an 800-volt electrical system, and multiple battery options—including a range-topping variant that supports DC fast charging at rates exceeding 320 kw. Such a rate typically enables 10-80% charges in 30 minutes or less.

Mercedes also said the batteries will differ in cell chemistry. The top-tier unit will feature cells with anodes that incorporate silicon oxide blended into graphite, which increases energy density and, as a result, helps deliver more range with less weight.

The automaker did not provide details on the 2-speed transmission, but in the MMA platform, a similar system enhances smoothness and efficiency rather than outright performance, as seen in the Porsche Taycan. For MMA-based EVs, first gear uses an 11:1 ratio and maxes out at 68 mph, while second gear shifts down to a 5:1 ratio, allowing for a top speed of 130 mph and optimizing highway efficiency. Mercedes stated that occupants will not notice the gear changes.

Both single-motor rear-wheel-drive and dual-motor all-wheel-drive variants are planned for the electric GLC-Class. For all-wheel-drive models, the front motor will disconnect when not needed to improve efficiency but will engage instantly when required. The motors will use inverters with silicon carbide technology, which reduces switching losses and enables higher switching frequencies, ultimately boosting range.

Another new feature of the MB.EA platform will be a compact brake module that integrates the brake booster, master cylinder, and stability control system—components that were previously separate. Mercedes claims this change will improve brake feel while optimizing energy recovery to further enhance range. According to the automaker, braking feel will remain consistent whether energy recovery or conventional friction brakes are being used. A hydraulic backup will also be in place in case of system failure.

Testing of the electric GLC-Class is currently underway near the Arctic Circle in northern Sweden, where temperatures at this time of year can drop to -40 degrees. Extreme cold typically affects battery range and performance, making such testing crucial for an EV. In the case of the electric GLC-Class, there’s also a new heat pump to evaluate.

The new design draws energy from three sources: waste heat from the electric motors, waste heat from the battery, and the surrounding air. The heat pump is part of the climate control system. For cooling, Mercedes said the system maintains cabin comfort even during fast charging when the battery generates excess heat, placing additional strain on the climate control system.

Mercedes plans to launch dozens of new models within the next 24 months, many of them EVs. Another model based on the MB.EA platform confirmed to be in the pipeline will be an electric E-Class.
