The next-gen Mercedes GLB will be offered with all-electric and hybrid powertrains globally, while retaining the unique three-row layout.
The initial EV lineup includes the GLB 250+ with EQ Technology and the GLB 350 4MATIC with EQ Technology, featuring a completely new design, interior, and electrical architecture.
Following its world premiere, we got to spend some time experiencing the design, features, and comfort of the next-gen model in the global specification. The new model has been confirmed to arrive as the 2027 Mercedes GLB in the U.S., and here’s what we found:
Design
The new GLB is 98 mm (3.9 in) longer, 27 mm (1.1 in) wider, 14 mm (0.6 in) lower, with a 60 mm (2.4 in) longer wheelbase compared to the EQB. It continues with an upright profile with a steep windshield and short overhangs.
The front end uses an illuminated panel with an animated pattern of 94 chrome-effect stars and an illuminated central star, while a full-width light band links the headlamps.
The rear uses star-themed taillights with a light element that stretches across the tailgate. A panoramic glass roof is standard, and an optional SKY CONTROL roof can switch between transparent and opaque sections.
Interior
The cabin uses the same layout as the new CLA Electric with an optional MBUX Superscreen spanning a 10.25-inch driver display, a 14-inch center display, and a 14-inch front passenger display behind a single glass surface.
A floating center console introduces additional storage and integrates cupholders and a smartphone tray with available wireless charging. The GLB runs on the new MB.OS with over-the-air updates for key vehicle software, and navigation is based on Google Maps.
Our experience in the GLB Electric
The Mercedes GLB Electric offers easy ingress and egress even for six-foot-tall people, thanks to the tall seating position. I found the front seats comfortable, with good back support and supportive side bolsters.
Headroom is generous even for my six-foot frame, and there is plenty of space around the pedals, including for size 12 shoes. Under-thigh support is very good for this class. Visibility is strong in all directions due to the large windows, with no issues at the front, sides, or rear.
The second row is also easy to access and remains comfortable for me. Headroom is very good, and legroom is sufficient, with space to slide my shoes under the front seats. Under-thigh support is average, but the seat offers reclining and fore-aft adjustment, which helps improve comfort.
Outward visibility remains good thanks to the large windows and quarter glass panels. Rear passengers get air-conditioning vents, USB ports, and a center armrest with cup holders and phone storage.
The optional third row is suitable only for children. Even then, I had to move the second-row seats forward to create usable space.
Specifications
Both electric models use an 85 kWh (usable) lithium-ion battery and an 800-volt MMA electrical architecture. The rear-wheel drive GLB 250+ makes 268 hp and 247 lb-ft, with an estimated 0-60 mph time of 7.3 seconds.
The all-wheel drive GLB 350 4MATIC develops 349 hp and 380 lb-ft, with an estimated 0-60 mph time of 5.4 seconds. WLTP range is listed at 542-631 km (337-392 miles) for the GLB 250+ and 521-614 km (324-382 miles) for the GLB 350 4MATIC.
DC fast charging is available at up to 320 kW, and the system is designed to add up to 260 km (162 miles) of WLTP range in 10 minutes.
The GLB 350 4MATIC includes a TERRAIN drive program and can be equipped with a surround-view parking system that enables a “transparent hood” view beneath the vehicle. Standard driver-assistance tech includes Distance Assist DISTRONIC, with additional functions available through Digital Extras.
Standard seating is for five, with an optional third row for seven occupants. The third-row seats are designed for passengers up to 5’6″ tall. An available sliding second-row seat can move 5.5 inches and allows multiple recline positions.
Cargo capacity is up to 19.1 cu ft (17 cu ft with the optional third row). With the rear seats folded, cargo space increases to 60.6 cu ft (56.7 cu ft with the optional third row). A front trunk adds additional storage.
