It’s been more than six years since Mercedes-Benz introduced the GLB, and in the intervening time it has occupied an interesting niche in the premium segment. Until today, there isn’t another compact three-row SUV from the established brands, which is presumably why Stuttgart has chosen to press on with a second generation unveiled today, at the expense of the much-loved A-Class.
Built on the same Mercedes-Benz Modular Architecture (MMA) as the also-new CLA, the GLB shares all that car’s bits, including an initial range of purely electric powertrains. It’s slightly larger than before and promises to offer increased practicality and a greater level of tech and intelligence.
At launch, the car can be had as either a GLB250+ or a GLB350 4Matic, both with the rather cumbersome “with EQ Technology” suffix. The base model has a single rear motor making 272 PS (200 kW) and 335 Nm of torque, along with a Porsche Taycan-style two-speed transmission to improve efficiency without sacrificing acceleration. It gets from zero to 100 km/h in 7.4 seconds and has a top speed of 210 km/h.

With dual-motor all-wheel drive, the GLB350 boosts outputs just a tad to 354 PS (260 kW) and 515 Nm, taking nearly two seconds out of the century sprint at 5.5 seconds. Both variants come with an 85 kWh (nett) NMC battery to deliver a WLTP-rated range of 542 to 631 km on the GLB250+ and 521 to 614 km on the less efficient all-paw GLB350.
Thanks to an 800-volt electrical architecture, the GLB is able to support up to 320 kW of DC fast charging, delivering 260 km of additional range with just ten minutes of charging. Unlike the CLA, it will also be able to charge at 400-volt stations at launch, although this is only possible through a DC converter that is frustratingly still optional. As for AC charging, the car will accept up to 22 kW; bidirectional charging is also available, enabled via a future over-the-air update.
Later on, the GLB range will be expanded with additional variants such as an entry-level version, along with three hybrid models. The latter, available with either front- or all-wheel drive, feature a motor and inverter built into the 8F-eDCT eight-speed dual-clutch transmission, plus a 1.3 kWh 48-volt battery and the ability to recuperate up to 25 kW through regen braking. The M252 1.5 litre turbo four-cylinder engine has reportedly been developed in partnership with Geely and is likely related to the BHE15 mill in the Proton X50.
All models are suspended on MacPherson struts at the front and a new multilink setup – adapted from Mercedes’ larger models – at the rear. They also come with a brake-by-wire system and are available with wheel sizes of up to 20 inches in diameter, at which point the car comes as standard with adaptive dampers.
The new GLB largely maintains the outgoing car’s proportions, its boxy shape and the distinctive thick, upright D-pillars. At the front, the rectangular LED headlights are joined together by an illuminated strip and feature Mercedes’ large and brash three-pointed star graphic, which form the daytime running lights on models with the optional Multibeam matrix units.
Lower down, there’s a massive octagonal grille with a dinner plate-sized badge, dual spars and 94 little stars. This entire panel is illuminated, including the central star in part or whole, depending on market regulations. The side profile has been cleaned up with pop-out door handles, while the taillights are now a continuous inverted U-shaped band of light spanning the entire width of the car, again with the star graphic. The rear number plate recess has been pushed downwards into the bumper.

Mercedes has put greater focus on aerodynamics this time around to make the GLB more efficient. The streamlined front and rear ends, sealed front shut lines, an optimised A-pillar and door mirror design, an almost completely covered underbody with front and rear wheel spoilers, and aerodynamic wheel designs help deliver a drag coefficient as low as 0.28, with a minimised spread across model lines and options.
Break out the measuring tape and you’ll realise that the new GLB is longer, wider but lower than its predecessor, measuring 4,732 mm long (+98 mm), 1,861 mm wide (+27 mm) and 1,687 mm tall (-14 mm). Its 2,889 mm wheelbase is 60 mm longer, enabling a 68 mm increase in second-row legroom.
Using a bespoke electrified platform also means that despite the reduction in height, the GLB offers significantly more headroom in the second and third rows compared to the old EQB. The last row is claimed to be able to “comfortably” fit adults up to 171 cm tall (three centimetres more than that EQB), although it does still lose out in headroom versus the previous petrol GLB, by a scant two millimetres.

As previously revealed, the interior continues to take after the CLA with a bluff, upright dashboard that serves as a full-width display panel, devoid of almost all buttons and switches. This can be outfitted with up to three screens as part of the optional MBUX Superscreen, with a 10.25-inch instrument display and twin 14-inch centre and passenger infotainment touchscreens.
These run on the latest Mercedes-Benz Operating System (MB.OS) that was introduced on the CLA, replete with ChatGPT and Google Gemini generative AI support. It supports Disney+ and Sony’s Ridevu streaming services, as well as Boosteroid cloud gaming that can be linked to a Bluetooth controller. Audio is taken care of through an optional 16-speaker, 850-watt Burmester 3D surround sound system.
In response to customer feedback, the steering wheel now features physical rocker and roller switches to adjust the cruise control speed and volume respectively, although the rest of the steering wheel controls are still capacitive touch units. As per the CLA, you also now only get two window switches on the driver’s door, with users having to thumb a button to switch between front and rear controls.
Elsewhere, you get round turbine-style corner air vents and rectangular centre vents that lead to a tall centre console. This houses a limited array of buttons, a Qi wireless charging tray and twin cupholders. There’s also a large panoramic glass roof, missing a powered sunshade but gaining a UV-reflective coating to reduce heat in the sun; an electrochromic frosting Sky Control unit with illuminated stars is optional.
As per the current model, the new GLB has an optional third row with ISOFIX child seat mounts; together with the second row and the front passenger seat, you can fit five child seats at once. The 40:20:40-split second-row has an optional sliding function, improving entry and egress for the third row thanks to a one-touch tilt-and-slide feature that moves a further 32 mm over the previous car, in concert with larger rear doors.
The boot measures 540 litres on the five-seater model and 480 litres on the seven-seater (with the third row folded), expandable to 1,715 litres and 1,605 litres respectively with the second row also folded. There’s also a 127 litre front boot on the electric version, the largest among Mercedes’ renewed compact car models.
Safety-wise, the GLB comes as standard with nine airbags, including a centre airbag and knee airbags for both front occupants; rear side ‘bags are optional. You also get a complete suite of sensors as standard in Europe that enable an entire suite of driver assists, all now packaged under the MB.Drive banner.
Optional features have to be unlocked through the Mercedes-Benz Store, including MB.Drive Assist Level 2 semi-autonomous driving with auto lane change, MB.Drive Assist Plus with enhanced highway auto lane change and MB.Drive Assist Pro with highly-automated city driving, the latter initially only in China. There’s also an improved MB.Drive Parking Assist that supports diagonal parking spaces, which can be optioned out with a 360-degree camera system as part of MB.Drive Parking Assist 360.
The new GLB is available to order in Germany now, with a market launch slated for the spring. Prices start from €59,048 (RM283,000) for the GLB250+ and €62,178 (RM298,000) for the GLB350.
