Your Questions About the 2027 Mercedes-Benz GLB, Answered

The 2027 Mercedes-Benz GLB is a fully redesigned electric SUV with available seating for up to seven. Two battery-electric variants launch the range — the rear-drive GLB 250+ with EQ Technology and the all-wheel-drive GLB 350 4MATIC with EQ Technology — with a 48-volt hybrid model to follow. Below, the team at Mercedes-Benz Rive-Sud in Longueuil answers the questions South Shore and Greater Montréal drivers are asking most.

How Far Can the 2027 GLB Drive on a Single Charge?

The GLB 250+ with EQ Technology offers up to 631 km of electric range (WLTP) from its 85-kWh lithium-ion battery. The all-wheel-drive GLB 350 4MATIC with EQ Technology reaches up to 614 km (WLTP) using the same battery pack. Both figures reflect WLTP testing standards; Canadian-market ratings may differ once confirmed by Natural Resources Canada. To put that into local context, a fully charged GLB 250+ covers easily the round-trip distance between Longueuil and Trois-Rivières.

How Fast Does It Charge?

The 2027 GLB uses an 800-volt electrical architecture that supports DC fast charging at up to 320 kW. At a compatible station, the battery can recover up to 260 km of range (WLTP) in approximately ten minutes. A standard DC converter is also included, which allows the GLB to charge at older 400-volt DC stations — useful given that Quebec's public charging network includes both voltage levels. For overnight home charging, the GLB accepts up to 9.6 kW through AC (Level 2).

Does It Lose a Lot of Range in Cold Weather?

Mercedes-Benz engineered the GLB's thermal management system specifically to reduce winter range loss. The heat pump draws warmth from three sources at once — waste heat from the electric motor, waste heat from the battery, and ambient air — requiring about one-third of the energy a conventional auxiliary heater would consume for the same output. The cabin heats twice as fast as the previous-generation model while using roughly half the energy. In cold-chamber testing at -15° Celsius, the windshield defrosts fully within 15 minutes using only the climate control system, with no manual intervention from the driver. When a DC charging stop is planned through the navigation system, the battery preconditions itself to an optimal temperature before arrival, preserving fast-charge speeds even in freezing conditions.

Is the Third Row Actually Usable?

The optional third row seats two passengers comfortably up to 5'5" tall — over one inch more headroom than the outgoing model. Access is easier than before thanks to wider rear door openings and 32 mm of additional Easy Entry adjustment range on the second-row seats, which slide forward on a 140-mm track. For families with older children or teenagers, the third row functions as a practical seating position rather than an afterthought. When not in use, the third-row seats fold flat into the cargo floor.

How Much Cargo Space Does It Have?

Behind the second row, cargo volume measures 540 litres in five-seat configuration or 480 litres with the optional third row installed. Fold all rear seats flat and that expands to 1,715 litres (1,605 litres in seven-seat models). The second-row backrests split in a 40/20/40 arrangement as standard, allowing long items to pass through the centre while two passengers remain seated. A 127-litre frunk under the hood provides additional enclosed storage — the largest in the GLB model family — for items like charging cables or groceries you'd rather keep separate from the main cabin.

How Many Child Seats Can It Fit?

Up to four. The second row accommodates two iSize child seats, and the optional third row accepts two ISOFIX seats. Mercedes-Benz notes this exceeds what most vehicles in the segment can support. All outer seating positions in the second and third rows include seat belts with pre-tensioners and force limiters, along with adjustable headrests.

What Are the Two Electric Models and How Do They Differ?

The GLB 250+ with EQ Technology drives the rear wheels through a single permanently excited synchronous motor producing 268 hp and 247 lb-ft of torque. A two-speed rear-axle transmission — an 11:1 first gear for low-speed response, a 5:1 second gear for highway efficiency — helps achieve 93 percent battery-to-wheel efficiency. The estimated 0–60 mph time is 7.3 seconds.

The GLB 350 4MATIC with EQ Technology adds a 107-hp front-axle motor for all-wheel drive, bringing combined output to 349 hp and 380 lb-ft. A Disconnect Unit decouples the front motor during light-load driving, cutting front-axle losses by up to 90 percent to protect range. When traction is needed — icy intersections, slushy highway merges — the front motor re-engages almost instantly. The estimated 0–60 mph time drops to 5.4 seconds.

Is There an AWD Option?

Yes. The GLB 350 4MATIC with EQ Technology provides all-wheel drive through its dual-motor layout. It also includes a TERRAIN drive program that adjusts drivetrain, steering, and brake characteristics for gravel or dirt roads, plus a transparent hood function (available with Digital Extra: MB.DRIVE PARKING ASSIST 360) that projects a virtual view beneath the vehicle using camera feeds. The upcoming hybrid variant will also launch with 4MATIC all-wheel drive.

What About the Hybrid Version?

Mercedes-Benz has confirmed a high-tech hybrid GLB will follow the electric launch models. It pairs a 1.5-litre four-cylinder gasoline engine (M 252, from the FAME engine family) with a 48-volt electric motor integrated into an eight-speed dual-clutch transmission. The system enables electric-only driving at city speeds when less than 27 hp is needed, and electric coasting up to approximately 100 km/h. A 1.3-kWh lithium-ion battery powers the electric motor, which can recuperate up to 25 kW of energy across all eight gears. The hybrid will initially arrive with 4MATIC all-wheel drive. Further specifications will be shared closer to its availability.

What Safety Features Come Standard?

Every 2027 GLB includes eight cameras, five radar sensors, 12 ultrasonic sensors, Digital Extra: Distance Assist DISTRONIC, and the PRE-SAFE preventive occupant protection system. PRE-SAFE can detect critical driving situations early and respond by pre-tensioning seat belts, closing windows, and repositioning the front passenger seat before a potential collision.

New for this generation: a centre airbag between the driver and front passenger, plus knee airbags for both front occupants. Window airbags extend from the A-pillar to the D-pillar, covering all three rows. The vehicle is also equipped with a water-cooled supercomputer designed with power reserves for future functions delivered through over-the-air updates.

What Optional Driver Assistance Packages Are Available?

Four Digital Extra packages expand on the standard equipment:

• MB.DRIVE ASSIST adds Steering Assist and Lane Change Assist to the standard Distance Assist DISTRONIC.
• MB.DRIVE ASSIST PLUS builds on that with market-specific functions, including Stop Sign and Traffic Light recognition.
• MB.DRIVE PARKING ASSIST identifies parking spaces on both sides of the vehicle and handles a variety of spot types — line slots, curb slots, garages, and angled parking. It can also exit a space automatically, even if the vehicle was parked manually.
• MB.DRIVE PARKING ASSIST 360 adds a 360-degree camera with improved surround-view displays and enables the transparent hood function on 4MATIC models.

What Infotainment System Does It Use?

The 2027 GLB runs on the Mercedes-Benz Operating System (MB.OS) with fourth-generation MBUX. The optional floating MBUX Superscreen spans the full dashboard width behind a single glass surface, housing a 10.25-inch driver display, a 14-inch central display, and a 14-inch front passenger display. The MBUX Virtual Assistant uses generative AI from ChatGPT4o, Microsoft Bing Search, and Google Cloud's Automotive AI Agent to handle natural-language conversations — covering navigation, vehicle questions, and general knowledge. Navigation is powered by Google Maps with Digital Extra: MBUX Navigation with Electric Intelligence, which plans routes including charging stops based on topography, temperature, traffic, and battery state.

Can I Personalize the GLB's Appearance?

Yes. Exterior styling packages include AMG Line, AMG Line Plus, and Night Package. Interior trims are offered in open-pore wood, brushed aluminum, anodized-look coating, and natural fibre. New paint options include Liquid Crystal Green and Sky Blue Metallic, and a new upholstery fabric with a pearl effect in Black/Clean White Pearl is available. The optional SKY CONTROL panoramic roof can switch its glass from transparent to opaque in milliseconds, and at night, 158 integrated stars illuminate in any colour matching the ambient lighting — eleven selectable ambient styles coordinate the instrument cluster, gauges, and cabin lighting around a visual theme.
