Mercedes-Benz launches the GLB with a new 48-volt hybrid powertrain offering electric driving, coasting, and recuperation across five model variants in Europe.
Mercedes-Benz has opened European orders for the new GLB with its high-tech hybrid drivetrain. The lineup features a 48-volt mild hybrid system across five variants. Three power levels are available, ranging from 136 to 190 horsepower. German pricing starts at €50,396.50 (approximately $58,200 USD).
Highlights
New electrified powertrain: A 1.5-liter four-cylinder turbo pairs with a 22 kW electric motor integrated into a new eight-speed dual-clutch transmission (8F-eDCT), supported by a 1.3 kWh lithium-ion battery.
Three output levels: System power ranges from 156 hp (115 kW) in the GLB 180 to 211 hp (155 kW) in the GLB 220, with front-wheel and 4MATIC all-wheel drive options.
Multi-mode hybrid operation: The system enables pure electric driving at city speeds, electric coasting up to 100 km/h, and energy recuperation across all eight gears at up to 25 kW.
Standard ADAS included: DISTRONIC Distance Assist comes standard, with optional MB.DRIVE ASSIST delivering SAE Level 2 capability including lane change assist.
Powertrain Architecture
The GLB's hybrid system centers on a newly developed electrified 1.5-liter four-cylinder turbo engine. An electric motor producing 22 kW and 200 Nm of torque is integrated directly into the new eight-speed dual-clutch transmission.
A 48-volt lithium-ion battery with 1.3 kWh capacity supplies the electric motor. The integrated design keeps the system compact and efficient. Mercedes-Benz stated the electric motor can provide an additional boost of 22 kW for up to 20 seconds at 3,000 rpm.
Hybrid Operating Modes
The system supports three distinct operating modes depending on driving conditions. At typical city speeds and with moderate throttle input, the GLB can run on electric power alone. The technical threshold is any driving situation requiring less than 22 kW of power.
On higher-speed roads, the drivetrain decouples for electric coasting at speeds up to approximately 100 km/h. Additionally, the electric motor recuperates energy in all eight transmission gears. Mercedes-Benz said the system can recover up to 25 kW during deceleration.
