Electrifying the Journey: The GLB EV
The spearhead of the 2027 GLB’s offensive is its all-electric variant, stepping confidently into the shoes of the outgoing EQB. Branded as the GLB EV with EQ Technology, this model represents Mercedes-Benz’s unwavering commitment to sustainable luxury. From a veteran’s standpoint, the specifications here are compelling and position the GLB EV as a significant contender in the burgeoning premium electric vehicle segment.
At its core, the GLB EV will launch with two primary configurations. The rear-wheel-drive GLB250+ will deliver a robust 268 horsepower and 247 lb-ft of torque. Mercedes-Benz’s decision to pair this with a two-speed automatic transmission is a clever engineering move, designed to optimize both snappy off-the-line performance (a 7.3-second 0-60 mph sprint is impressive for a family-focused EV) and cruising efficiency. For those demanding elevated traction and performance, the all-wheel-drive GLB350 4Matic ups the ante significantly. This dual-motor setup integrates a 107-hp front motor, working in tandem with a slightly de-rated 242-hp rear motor to achieve a combined output of 349 horsepower and 380 lb-ft. This power allows the GLB350 4Matic to rocket from 0-60 mph in a brisk 5.4 seconds, making it one of the quicker options in the luxury compact EV space. The intelligent activation of the front motor only when needed for performance or traction further speaks to Mercedes-Benz’s optimization efforts, balancing power with efficiency.
Powering these impressive figures is an 85-kWh battery pack, designed with an advanced 800-volt architecture. This isn’t just a marketing buzzword; 800-volt charging is a game-changer for reducing charge times. The GLB EV is estimated to accept DC fast charging at an astonishing rate of up to 320 kW. This translates into rapid energy replenishment, with Mercedes-Benz projecting an additional 162 miles of range in just 10 minutes—a crucial factor for drivers on long journeys. Crucially, and a distinct advantage over some competitors, the GLB EV will feature a built-in DC converter. This allows seamless charging on older 400-volt chargers without needing special adapters, expanding its utility significantly.
On the range front, Mercedes-Benz anticipates a WLTP estimated range between 323 and 392 miles. While the more stringent EPA cycle for the U.S. market typically yields slightly lower figures, we can still expect a highly competitive GLB EV range that comfortably covers most daily commutes and weekend adventures. Furthermore, in a significant move towards user convenience, Mercedes-Benz is embracing the Tesla-designed NACS charging port as standard. This means GLB EV owners will have direct access to the vast and reliable Tesla Supercharger network, a considerable competitive advantage in the competitive luxury EV market. An adapter will also be provided to ensure compatibility with existing CCS-type chargers, solidifying the GLB EV’s charging versatility. This comprehensive charging solution addresses a major pain point for potential EV owners, cementing the GLB EV as a practical and desirable choice for those ready to embrace an all-electric future.
The Hybrid Evolution: Bridging Traditional and Electric
While the all-electric GLB commands much of the future-oriented discussion, Mercedes-Benz understands that the transition to full electrification is a journey, not a destination for every buyer. Thus, the 2027 GLB will also offer a sophisticated hybrid powertrain, following a similar rollout schedule to the EV, hitting dealerships a few months later. From my decade of observing market trends, this dual strategy is intelligent, catering to those who desire efficiency and reduced emissions without full reliance on charging infrastructure. This positions the GLB Hybrid as a highly attractive option in the premium hybrid SUV segment.
Though Mercedes-Benz has yet to release explicit details for the GLB Hybrid, we can make highly educated guesses based on the CLA’s recently announced hybrid specifications. It’s almost certain the GLB will adopt the same innovative drivetrain: a 1.5-liter turbocharged inline-four engine, operating on the fuel-efficient Miller combustion cycle. This engine is mated to an advanced eight-speed dual-clutch automatic transmission, which cleverly integrates a potent 30-horsepower electric motor. The combined system output of 208 horsepower and a robust 280 lb-ft of torque provides ample motivation for the GLB, likely propelling it to 60 mph in a respectable sub-8-second timeframe.
The elegance of this hybrid system lies in its operational flexibility. The integrated electric motor allows for short bursts of all-EV driving, perfect for navigating urban environments silently and emission-free. An additional clutch in the gearbox facilitates the complete decoupling of the gasoline engine during coasting or pure electric propulsion, maximizing fuel economy. Drivers will also appreciate the manual gear change option, accessible via intuitive column shifters.
Mercedes has confirmed that the GLB Hybrid will be available in both front-wheel drive and the brand’s renowned 4Matic all-wheel-drive system. The 4Matic variant, like its CLA counterpart, is expected to feature a sophisticated system that can disconnect the rear axle when not needed, optimizing efficiency during cruising. However, when traction or performance demands arise, up to 40 percent of the power can be instantaneously routed to the rear wheels, ensuring confident handling and grip in diverse conditions. This intelligent power delivery system underscores Mercedes-Benz’s commitment to engineering both performance and efficiency into every GLB, cementing its appeal for a broad audience seeking a versatile and efficient Mercedes GLB SUV.
Dynamic Versatility: Chassis and Handling
Beyond the powertrains, the 2027 GLB’s underpinnings have been meticulously engineered to deliver a driving experience befitting a Mercedes-Benz. While it retains its practical, upright stance, the integration of advanced chassis technology ensures it doesn’t sacrifice dynamic capability for utility.
For those venturing beyond the pristine tarmac, all-wheel-drive GLB models will come equipped with a dedicated Terrain driving mode. This mode intelligently optimizes the vehicle’s traction control, throttle response, and transmission mapping to maximize grip on loose surfaces like gravel or snow. Complementing this, if equipped with the optional 360-degree camera system, the GLB offers a truly innovative “transparent hood” feature. This utilizes the center screen to display a virtual view of the ground directly beneath the front of the vehicle, invaluable for navigating tricky off-road obstacles or tight parking situations. It’s a clever piece of next-gen infotainment system integration that directly enhances real-world usability.
Buyers seeking to fine-tune their driving dynamics will appreciate the optional adaptive dampers. These electronically controlled shock absorbers allow the driver to switch between comfort-oriented and sportier suspension settings, adapting to varying road conditions and personal preferences. While these adaptive dampers require opting for the larger 20-inch wheels, buyers can also choose from standard 18- and 19-inch wheel designs, each offering a distinct aesthetic and ride quality balance. From my perspective, the availability of adaptive dampers in a compact SUV of this caliber is a crucial differentiator, allowing the GLB to truly offer a tailor-made driving experience that transcends its segment. It underlines the GLB’s ambition to be a refined daily driver and a capable adventure companion, solidifying its position as a truly versatile luxury compact SUV.

For those craving the ultimate digital experience, the optional “Super Screen” takes things a step further, adding a third 14.0-inch passenger display. Mercedes-Benz has thoughtfully integrated a clever privacy feature here: if the driver glances at the passenger screen for more than 1.3 seconds while the vehicle is in motion, the screen automatically dims, minimizing distraction and maintaining focus on the road – a critical safety and advanced automotive technology consideration.
The MBUX Virtual Assistant, a cornerstone of Mercedes-Benz’s user experience, receives a significant upgrade in the new GLB. Thanks to advanced AI programming, it now boasts conversational capabilities and even short-term memory. This means interacting with your car becomes far more intuitive. Instead of rigid command trees, you can fluidly ask the system to “find me the nearest NACS charger with a coffee shop nearby” or “locate a highly-rated vegan restaurant.” This natural language processing elevates the next-gen infotainment system to new heights, making daily interactions effortless and enjoyable. Furthermore, the navigation system integrates seamlessly with built-in Google Maps, offering cloud-based EV route and charge planning, a critical feature for optimizing electric journeys.
Where the GLB truly differentiates itself from its sedan sibling, and indeed many rivals, is in its interior volume and practical utility. Its boxier silhouette translates directly into significantly more passenger space. The new model benefits from a 2.4-inch longer wheelbase, directly enhancing legroom for both first and second-row occupants. Headroom, often a concern in compact SUVs, is also improved thanks to a standard panoramic sunroof. For an added touch of luxury and innovation, the optional Sky Control panoramic sunroof allows occupants to instantly switch the glass from clear to opaque with the push of a button. At night, a dazzling display of 158 three-pointed stars embedded in the glass illuminates, creating a truly unique ambiance that screams sustainable luxury vehicles.
The GLB’s calling card remains its optional third row, transforming it into a versatile seven-seat SUV. Mercedes-Benz has further enhanced usability here, with second-row seats that now slide farther forward, making access to the very back significantly easier. While the third row is still best suited for children, an average-height adult can technically fit for shorter journeys, a testament to the efficient packaging.
Cargo capacity is also robust. The GLB EV offers 19.1 cubic feet with five seats in place, expanding to 17 cubic feet with the third row folded down. While the capacity with all seven seats deployed isn’t specified, expect enough room for a duffel bag or small groceries. A standout feature for the EV variant is its substantial 4.5-cubic-foot frunk (front trunk), a practical space larger than that found in a Tesla Model Y, ideal for charging cables or smaller items. While hybrid cargo specifications are yet to be fully detailed, they are expected to be similar, minus the frunk. This emphasis on flexible seating and generous cargo capacity makes the 2027 GLB a compelling choice for families seeking a premium yet practical urban family SUV.
