The GLB adopts a revised exterior focused on proportion and efficiency
The new GLB introduces a revised exterior profile centered on proportion, aerodynamics, and increased visual stability. Mercedes-Benz extended the wheelbase by 2.4 inches, resulting in improved stance and contributing to a more spacious cabin for occupants in both the first and second rows. The longer wheelbase also aids ride comfort by allowing the suspension geometry to operate over a broader range, complementing optional adaptive damping that can be tuned for either comfort or more controlled responses.
Design changes focus on reducing visual clutter while highlighting functional surfaces. The clean shoulder line and minimized creases contribute to the vehicle’s 0.28 drag coefficient, a figure that directly impacts overall efficiency—particularly important for the fully electric variants. Although the frontal area is slightly larger than that of the previous EQB, Mercedes-Benz notes that aerodynamic resistance has decreased overall due to the interplay of refined underbody paneling, reshaped fascia components, and more favorable airflow around the mirrors and A-pillars.
The GLB’s upright front, short overhangs, and compact greenhouse are intended to preserve the SUV’s traditional shape while integrating modern lighting and surface treatments. Standard LED lighting elements connect visually across the body, and the grille incorporates 94 illuminated chrome-effect Mercedes-Benz stars in electric variants. These changes appear subtle in motion but support the automaker’s goal of creating a consistent identity across its electric product lines.
Rear styling emphasizes width, lighting continuity, and packaging improvements
Viewed from the rear three-quarter angle, the GLB’s updated lighting signature becomes particularly apparent. The full-width light band between the taillights creates a visual link to the front fascia’s illuminated components. Mercedes-Benz designed the taillights to integrate the brand’s star motif in chrome-plated form, reinforcing consistency with other models in its growing electric portfolio. For models equipped with the LED Intelligent Light System, these lighting components incorporate welcome and farewell animations.
The increased wheelbase contributes directly to improved rear packaging. Second-row passengers gain up to 2.7 inches of extra legroom compared to the previous EQB, while headroom also increases due to the revised roof contour and standard panoramic roof. When equipped, the third row is designed to seat occupants up to 5 feet 6 inches tall, with ingress improvements achieved through a 1.3-inch increase in Easy Entry seat travel and larger rear door openings. These changes reflect Mercedes-Benz’s effort to position the GLB as an everyday-use SUV rather than one optimized solely for range or design expression.
Aerodynamic optimization continues at the rear, where a reshaped bumper and carefully positioned spoilers reduce turbulence and improve flow separation. Engineers devoted particular attention to aeroacoustics, including wind noise generated around the tailgate edges and rear pillars. The brand states that microphones and artificial-head recordings were used to identify and mitigate localized noise sources, which contribute to long-distance comfort—especially at highway speeds where aerodynamic noise becomes dominant.
The GLB’s reworked cabin prioritizes digital integration and simplified forms
Inside, the GLB adopts a reinterpreted interior design that replaces its previous sculptural layout with a simplified architectural approach. Central to the redesign is the optional MBUX Superscreen, which merges a 10.25-inch driver display, a 14-inch central display, and a 14-inch passenger display beneath a single glass panel. This configuration is powered by MB.OS and supported by real-time graphics rendering from the Unity game engine, allowing the system to present more detailed visualizations and reorganized menu structures.
Mercedes-Benz reworked the dashboard, door panels, and center console to reduce form complexity. Round air vents appear to float outward from the paneling and are finished with metallic elements that contrast with the surrounding materials. The center console provides expanded storage and incorporates a redesigned surface that integrates cupholders and wireless charging as applicable. Mercedes-Benz also reintroduced physical controls for volume and Distronic functions based on customer feedback, aiming to preserve tactility where beneficial.
Ambient lighting and trim materials play a larger role in perceived cabin quality. New upholstery options, including leather and fabric combinations with pearl effects, aim to create a more contemporary palette. Paired with the redesigned panoramic roof and improved seating geometry, the GLB’s interior is intended to feel both more open and more technically oriented than before, while maintaining ergonomic familiarity for longtime Mercedes-Benz customers.
A broader view of the front cabin highlights MB.OS, lighting, and structural changes
From this angle, the expansive width of the MBUX Superscreen becomes clearer, demonstrating how much of the dashboard’s architecture has been reorganized around digital elements. MB.OS underpins the interface and allows the vehicle to receive over-the-air software updates affecting driver-assistance systems, infotainment features, and other operational components. This long-term update capability is designed to extend the functional lifespan of the GLB’s electronics and preserve feature parity with future Mercedes-Benz models.
The seating shown here reflects improvements in comfort through revised foam structures, increased thigh support in the second row, and modified hip angles intended to distribute weight more evenly. These changes contribute to reduced fatigue during longer drives and support Mercedes-Benz’s claim of improved long-distance usability, particularly in EV configurations where extended-range driving may be more common. Paired with an upgraded heat-pump system derived from the Vision EQXX research program, the GLB’s climate control system can warm the cabin twice as fast as its predecessor while using approximately half the energy.
The lighting elements along the door panels, footwells, and instrument area connect with the GLB’s ambient lighting suite, which offers multiple themes coordinated with display colors and visual motifs. These modes are especially prominent at night or when combined with the available Sky Control roof, which can illuminate embedded star patterns. This visual harmony is part of Mercedes-Benz’s broader strategy to unify digital and physical design elements.
The third-row configuration demonstrates improved accessibility and expanded usability
The GLB’s optional third row is designed to accommodate two passengers with height recommendations up to 5 feet 6 inches. While compact, Mercedes-Benz emphasizes that this row benefits from improvements to both headroom and footwell depth due to changes in the vehicle’s floor structure and roof contour. The seats fold flat into the load floor when not in use, allowing the GLB to maintain flexibility between passenger capacity and cargo space.
Ingress and egress improvements stem from the Easy Entry system, which now offers 1.3 additional inches of travel. This allows the second-row seat to slide farther forward while maintaining enough clearance for occupants to step into the third row. Rear door openings have also been enlarged to enhance accessibility. These changes are particularly relevant for families or users who regularly transport more than five occupants, as few vehicles in this segment offer seating for seven with comparable ease of entry.
Child seat accommodation is an additional focus. Mercedes-Benz highlights that the GLB can support up to four child seats across the second and third rows, a capability uncommon among compact SUVs. Safety systems—including window airbags that extend across all seating rows—further support the vehicle’s positioning as a family-oriented model. These improvements reflect the manufacturer’s aim of combining electric-vehicle efficiency with practical utility and safety considerations.
Two-tone cabin option showcases material variation and individualized configuration
This interior variant highlights the GLB’s expanded catalog of trim materials and upholstery options. Mercedes-Benz allows customers to select from multiple combinations of leather, fabric, and synthetic materials across different color schemes. The example shown integrates contrasting black and white seating surfaces with coordinated stitching and door-panel inserts. This configuration aligns with the brand’s emphasis on personalization within its Entry Luxury portfolio.
The Sky Control panoramic roof is visible here, demonstrating its embedded LED star pattern. This roof uses switchable glass technology that can transition between transparent and opaque states within milliseconds. The opacity modes help control glare and cabin brightness, while the illuminated stars contribute to visual ambiance at night. These elements tie into the GLB’s broader lighting strategy, which coordinates instrument cluster themes, ambient lighting colors, and display motifs.
The cabin surfaces incorporate a combination of textured metals, soft-touch materials, and high-gloss components. Mercedes-Benz notes that many trim elements are available in open-pore wood, brushed aluminum, and natural fiber finishes, allowing users to tailor the environment based on aesthetic preferences. The GLB’s center console and dashboard are designed to maintain ergonomic predictability across these variations, ensuring that material changes do not alter functional layout.
A full-cabin perspective highlights spatial improvements and updated ergonomics
This final view provides a clear representation of the GLB’s front-row ergonomics and spatial arrangement following its redesign. The steering wheel integrates capacitive panels supplemented by physical rollers and switches, reinstated to improve usability for functions such as volume control and Distronic operation. The simplified forms of the dashboard and doors present more continuous surfaces than in the previous model, contributing to a more modern appearance that aligns with the brand’s larger vehicles.
The cabin geometry is informed by changes to the GLB’s exterior dimensions. Increased headroom in both the first and second rows results from the revised roof structure, while the expanded wheelbase contributes to legroom gains. Mercedes-Benz emphasizes that these spatial adjustments are not merely numerical but translate to improved comfort, especially during extended drives. The front seats are supported by structural enhancements aimed at reducing vibration and improving posture support.
Complementing these physical changes, MB.OS enables deeper personalization of digital elements. Users can reorganize app grids, create folders, and rely on the system’s updated Zero Layer interface, which prioritizes contextually relevant information without requiring multiple menu layers. This organizational approach was developed to reduce distraction and maintain consistency with consumer electronics interfaces, extending the GLB’s digital usability beyond typical automotive norms.
