At launch, the electric GLB lineup includes two models built on an 800-volt electrical architecture and designed to support fast charging and longer driving range.

“The GLB brings Mercedes-Benz design into a new era for this segment,” said Gorden Wagener, chief design officer, Mercedes-Benz Group AG.

Powertrain, Range, And Charging

At launch, the electric GLB portfolio includes:

  • GLB 250+ With EQ Technology (268 hp)

  • GLB 350 4MATIC With EQ Technology (349 hp)

Both models use an 85-kWh usable lithium-ion battery. Mercedes-Benz lists up to 631 km of electric range (WLTP) for the GLB 250+.

The 800-volt architecture enables DC fast charging up to 320 kW at compatible stations. Mercedes-Benz says the GLB can add up to 260 km (WLTP) of range in 10 minutes. A DC converter is standard to support charging at 400-volt DC fast chargers.
