The Baby GLS Arrives: Why the 2027 Mercedes GLB is the New Benchmark for Family EVs
The days of choosing between a dorky-looking electric bubble and a cramped combustion conversion are officially over. Mercedes-Benz is shaking up the family segment with the 2027 GLB, a vehicle that has grown into its own skin to earn the nickname baby GLS. By stretching the frame to over 4.7 meters and moving to a dedicated electric-first architecture, the German automaker is proving that practicality and high-end tech can finally coexist in a boxy, rugged package.
Perhaps the biggest news for longtime fans is a shift in naming. The confusing EQB badge is headed for the retirement home. In an effort to make things simple, Mercedes is keeping the GLB name across the board for petrol, hybrid, and electric versions. You will still be able to spot the electric model on the street, though, thanks to a closed-off grille featuring a galaxy of illuminated stars and those sharp new three-spoke daytime running lights.
Under the hood—or rather, under the floor—is where the real magic happens. While many competitors are sticking with older 400-volt setups, the new GLB jumps to an 800-volt system. This means you can blast the battery from 10 to 80 percent in just 22 minutes. If you are in a rush, a quick ten-minute stop adds about 260 kilometers of range. Even more impressive is the inclusion of a two-speed gearbox on the rear axle. This is a rarity usually found in high-performance sports cars, allowing for better torque when towing heavy loads and improved efficiency when cruising on the highway.
Inside, Mercedes is listening to its customers by bringing back physical buttons. The brand has ditched the frustrating touch sliders on the steering wheel in favor of tactile rollers and switches. It is a win for ergonomics and safety, allowing drivers to keep their eyes on the road. The tech suite is equally upgraded, using a dual-brain AI system. Google Gemini handles the complex navigation and outside world queries, while ChatGPT manages your internal comforts like climate control and lighting.
The cabin experience is rounded out by some truly unique features, including a Sky Control glass roof that can change its tint electronically and even mimic a starry night sky with integrated LEDs. For those who enjoy a specific vibe while driving, the new Sound Worlds feature includes edgy audio themes like Fractal Fusion.
Practicality remains the GLB's strongest selling point. The longer wheelbase makes jumping into the optional third row much easier, and there is a massive 127-liter frunk for stowing charging cables. For those who need to haul more than just groceries, the 2,000kg towing capacity is supported by an invisible bonnet camera system that lets you see through the front of the car on your screen for perfect maneuvering.
It is not all perfect, however. In a strange move toward minimalism, Mercedes has reduced the driver-side window controls to just two switches, requiring a toggle button to operate the rear glass. It is a small quirk that might irritate those used to the standard four-switch layout.
With a starting price of 54,000 euros, climbing up to 64,000 euros for the AMG Line 350 4MATIC, this is a premium machine with a premium price tag. While it faces stiff competition, the combination of supercar-level charging speeds and genuine seven-seat utility makes it a very tempting upgrade for the modern family.
