Mercedes-Benz has unveiled the latest generation of its GLB, and although its overall shape still honors the squared-off, upright look that defined the original, the new model introduces a wide range of significant changes beneath its familiar exterior. For 2026, the GLB arrives first as a purely electric SUV, positioned as a de facto successor to the EQB despite carrying a different badge. Buyers will eventually see hybrid variants added to the lineup, but Mercedes has chosen to launch the new GLB exclusively with electric powertrains.
Visually, the 2026 model adopts the bolder design direction seen in Mercedes’ newest vehicles, such as the CLA and the GLC EQ. The front fascia now features a much larger grille area, supported by headlights that have been thoroughly redesigned. These lights incorporate decorative star-shaped daytime running lamps and are tied together by a prominent light bar stretching across the nose. While this updated face may not transform the GLB into a classically beautiful SUV—much like its predecessor—it certainly gives it a more modern and expressive character. Around the back, the design becomes even more distinctive. The taillights draw inspiration from the styling cues of the experimental EQXX Concept, using vertically oriented units connected through a thin illuminated strip. The repeating star motif appears here as well, reinforcing the new visual identity Mercedes is building for its electric offerings.
Dimensionally, the updated GLB has grown compared with both the retired EQB and the earlier gasoline-powered GLB it effectively replaces. Its total length now measures 4,732 mm, making it 48 mm longer than the EQB and nearly 100 mm longer than the previous GLB. Width has increased to 1,861 mm—an extra 27 mm over both older models—while height has slightly decreased to 1,687 mm, representing a modest 14 mm reduction. The wheelbase benefits from the most meaningful expansion, stretching to 2,889 mm. This 60 mm increase should translate into noticeably improved cabin space, especially for passengers in the second row. Cargo capacity has also improved, offering 667 liters in the rear trunk along with an additional 127 liters of storage up front.
Inside the cabin, Mercedes has taken a major leap forward in technology. Buyers can specify the optional Superscreen layout, combining a 10.25-inch digital gauge display with a pair of 14-inch screens—one serving as the central infotainment unit and the other dedicated to the front passenger. The dashboard design follows the brand’s new minimalist trend, appearing flat and clean with few ornamental details. This setup runs the latest fourth-generation MBUX system, enhanced with AI capabilities from Microsoft and Google. The interface itself is built on the Unity engine and incorporates the MBUX Virtual Assistant powered by ChatGPT-4o, signaling Mercedes’ intent to push digital innovation to the forefront of the GLB experience.
Two electric versions will be available at launch. The GLB 250+ with EQ Technology uses an 85-kWh lithium-ion battery paired with an 800-volt electrical system. Its single rear motor produces 268 hp and 247 lb-ft of torque continuously, with momentary boosts to 335 lb-ft. It completes the 0–100 km/h sprint in 7.4 seconds and delivers an estimated 630 km of driving range, strong numbers for a compact electric SUV. Above it sits the GLB 350 4Matic, which adds a motor to the front axle for all-wheel-drive capability. This version generates a combined 349 hp and 380 lb-ft of torque. Its range dips slightly to 615 km, but performance improves significantly, dropping the 0–100 km/h time to 5.5 seconds. Mercedes also plans to introduce a more budget-friendly electric entry model next year, along with a mild-hybrid variant using 48-volt assistance. In total, three power outputs will be offered across FWD and AWD setups.
At the moment, pricing details are available only for Germany. The GLB 250+ starts at €59,040, while the 350 4Matic begins at €62,178. U.S. pricing remains unannounced, but a similar pricing gap is expected once the model reaches global markets in 2026.
