Mercedes GLB Electric Specs

Mercedes-Benz says its new electric GLB can travel up to 631 kilometers, or about 392 miles, and still seat as many as seven people. (mercedes-benz.com) The company’s product page says the sport utility vehicle can add up to 260 kilometers of range in 10 minutes on a fast charger. Mercedes also says the electric version includes a front trunk and a flexible third row with two extra seats. (mercedes-benz.com) Cars.com reported on December 8, 2025, that Mercedes has not released United States Environmental Protection Agency range figures yet. The 392-mile number comes from European testing, which usually produces higher results than United States ratings. (cars.com) Cars.com also reported that both electric GLB versions use an 85-kilowatt-hour battery pack and an 800-volt electrical system. That setup allows charging speeds of up to 320 kilowatts on a direct-current fast charger. (cars.com) Mercedes is pitching the GLB as a compact family vehicle rather than a low-slung sedan. The company says the cabin adds legroom and headroom, while the optional third row lets the GLB carry up to seven passengers. (mercedes-benz.com) That matters because battery-electric sport utility vehicles with three rows are still relatively rare, especially in the premium compact segment. Cars.com said buyers wanting an electric SUV with three rows and a luxury badge had essentially one direct predecessor here: the vehicle previously sold as the Mercedes-EQ EQB. (cars.com) Mercedes has also reworked the powertrain. Cars.com said the rear-wheel-drive GLB 250+ makes 268 horsepower, while the all-wheel-drive GLB 350 4Matic adds a front motor for a combined 349 horsepower. (cars.com) The range gain comes from more than a bigger battery. Cars.com said Mercedes paired more efficient motors with a two-speed transmission on the rear motor and a front motor that engages only when needed on all-wheel-drive models. (cars.com) Mercedes is not making the GLB an electric-only nameplate forever. Cars.com reported that a hybrid version with a 1.5-liter turbocharged four-cylinder engine and a small 1.3-kilowatt-hour battery will join the lineup later. (cars.com) For now, the headline is simple: Mercedes is trying to turn the GLB into an electric family hauler that keeps the boxy shape, the extra seats, and the long-distance promise buyers expect from a gasoline sport utility vehicle.
