The MMA platform ensures that whether you opt for the exhilarating silence of electric power or the reliable efficiency of a hybrid, you’re getting a vehicle that feels purpose-built and thoroughly modern, not an adaptation.
Electrifying Versatility: The GLB EV’s Ambitious Charge
The fully electric variant of the 2027 GLB, effectively taking the reins from the outgoing EQB, is where Mercedes-Benz truly flexes its future-forward muscles. This isn’t just an EV; it’s a meticulously engineered electric luxury compact SUV designed to address critical aspects of range anxiety, charging speed, and dynamic performance, all within a family-friendly package.
The GLB EV will initially launch with two compelling configurations. The rear-wheel-drive GLB 250+ with EQ Technology will serve as the base, delivering a robust 268 horsepower and 247 lb-ft of torque. Power is channeled through a sophisticated two-speed automatic transmission – an unusual but effective choice in EVs, geared for both instantaneous acceleration off the line and optimized efficiency during highway cruising. Mercedes-Benz anticipates a respectable 0-60 mph sprint in 7.3 seconds for this variant.
For those demanding more spirited performance and enhanced traction, the all-wheel-drive GLB 350 4Matic with EQ Technology steps up to the plate. This model integrates an additional 107-hp front motor, complementing a de-rated 242-hp rear motor to achieve combined outputs of 349 horsepower and a significant 380 lb-ft of torque. The front motor intelligently engages only when additional performance or traction is required, maximizing efficiency when it’s not. This dual-motor setup drastically cuts the 0-60 mph time to an estimated 5.4 seconds, making it a genuinely quick luxury compact SUV.
Powering these impressive figures is an 85 kWh battery, offering substantial energy capacity. While Mercedes-Benz’s initial estimates of 323 to 392 miles are based on the more lenient WLTP test cycle, expert projections for official U.S. EPA range place it solidly in the competitive upper 200s to low 300s, a crucial benchmark for the 2025 electric vehicle market.
However, the true game-changer lies in its 800-volt battery architecture. This advanced system allows for incredibly rapid charging at up to 320 kW on compatible 800-volt chargers. What does this mean for the real-world user? A staggering 162 miles of range can be added in just 10 minutes, fundamentally transforming the perception of EV convenience and alleviating range anxiety for cross-country trips. Furthermore, Mercedes-Benz has thoughtfully integrated a DC converter, enabling seamless charging on older 400-volt chargers without the need for cumbersome adapters, a practical advantage over some competitors.
And here’s where the 2027 GLB EV truly future-proofs itself: it will feature the Tesla-designed North American Charging Standard (NACS) port as standard. This is a monumental shift for the industry and a massive benefit for consumers, allowing GLB owners direct access to Tesla’s vast and highly reliable Supercharger network across the U.S. For existing CCS-type chargers, a simple adapter will ensure backward compatibility, providing unparalleled charging flexibility and making the GLB EV one of the most accessible electric vehicles on the market from a charging infrastructure perspective. To top it all off, the GLB EV boasts a practical 4.5-cubic-foot “frunk” (front trunk), a convenient addition for charging cables or smaller items, and notably larger than what you’d find in a Tesla Model Y. This meticulous attention to detail highlights Mercedes-Benz’s commitment to delivering a truly user-centric electric experience.
The Intelligent Bridge: The GLB Hybrid Powertrain for Uncompromised Versatility
While the allure of pure electric driving is undeniable, the realities of the 2025 market still see a significant demand for sophisticated hybrid solutions. For many, a hybrid represents the perfect bridge technology – offering enhanced fuel economy, reduced emissions, and the security of a gasoline engine for extended range, without the need for dedicated charging infrastructure on every trip. The 2027 GLB Hybrid is engineered precisely for this discerning segment.
Following a similar staggered rollout to the CLA, the GLB Hybrid will arrive in dealerships a few months after its electric sibling, a strategic move to cater to diverse customer preferences. While Mercedes-Benz has yet to release granular details on this specific variant, a decade of observing their powertrain strategies allows for highly accurate prognostication. It’s virtually certain that the GLB Hybrid will adopt the same sophisticated drivetrain found in the new CLA.
This setup centers around a highly efficient 1.5-liter turbocharged inline-four engine, operating on the fuel-saving Miller combustion cycle. This engine is seamlessly integrated with an eight-speed dual-clutch automatic transmission that houses a potent 30-horsepower electric motor. The combined system output is expected to be a robust 208 horsepower and 280 lb-ft of torque. This intelligent pairing not only delivers brisk acceleration – likely enabling the GLB Hybrid to reach 60 mph in a manufacturer-estimated low-to-mid 7-second range – but also remarkable fuel efficiency. An additional clutch within the gearbox is a subtle yet significant engineering marvel, allowing the gasoline engine to be entirely disconnected for pure EV driving at lower speeds or for “sailing” (coasting) to maximize fuel economy.
The GLB Hybrid will be offered in both front-wheel-drive and the renowned 4Matic all-wheel-drive configurations. Similar to the CLA Hybrid, the GLB 4Matic Hybrid will intelligently disengage the rear axle when all-wheel drive isn’t required for traction or performance, further optimizing fuel consumption. However, when conditions demand it, up to 40 percent of the power can be instantaneously sent to the rear wheels, providing confident grip and enhanced driving dynamics. This intelligent power distribution ensures that the GLB Hybrid remains a versatile and capable companion for a wide range of driving conditions, from urban commutes to inclement weather. The ability to manually change gears by nudging the column shifter also adds a layer of driver engagement, a subtle nod to Mercedes-Benz’s commitment to driving pleasure even in an efficiency-focused package.
Beyond the Pavement: All-Road Capability for the Modern Explorer
While the GLB might not be designed for extreme rock crawling, its “All Road Ready-ish” moniker accurately reflects its enhanced capabilities for those seeking adventure beyond pristine asphalt. This is a compact luxury SUV that understands the needs of a modern family, ready to tackle gravel roads, snowy passes, or simply provide peace of mind in challenging conditions.
All-wheel-drive models will benefit from a dedicated “Terrain” driving mode. This specialized setting optimizes the powertrain, traction control, and stability control systems to maximize grip on loose surfaces such as dirt, sand, or snow. It’s an intelligent system designed to instill confidence in situations where standard drive modes might falter, making it a perfect companion for weekend getaways or navigating unpaved trails to a scenic viewpoint.
Adding a touch of cutting-edge technology to this capability, if equipped with the optional 360-degree camera system, the GLB offers an innovative “transparent hood” feature. This ingenious system utilizes the center infotainment screen to display a virtual view of the ground directly underneath the front of the vehicle. For drivers navigating uneven terrain, tight parking spaces, or even just avoiding curb rash, this feature provides invaluable visual assistance, allowing them to precisely place the front wheels and avoid potential obstacles. It’s a blend of luxury and practicality that truly enhances the driving experience.
When it comes to ride comfort and handling, Mercedes-Benz offers further customization. Adaptive dampers are available as an option, but they require selecting the larger 20-inch wheels. This combination allows the GLB’s suspension to dynamically adjust to changing road conditions and driving styles, providing a smoother ride on rough surfaces and tighter body control during spirited driving. For those preferring a slightly different aesthetic or ride characteristic, 18-inch and 19-inch wheel options are also available, ensuring a tailored experience for every owner. These thoughtful inclusions underscore the GLB’s commitment to providing both everyday refinement and the capability to venture off the beaten path with confidence, a key differentiator in the competitive 2025 luxury compact SUV segment.
A Sanctuary of Innovation: The GLB’s Interior Experience Redefined
Step inside the 2027 GLB, and you’re immediately immersed in a cabin that marries cutting-edge technology with thoughtful, spacious design. While sharing the modern, upright dashboard aesthetic of the CLA, the GLB carves out its own distinct identity through sheer volume and unparalleled versatility. This interior isn’t just a place to sit; it’s a command center, a lounge, and a sanctuary, all rolled into one.
Dominating the cockpit is a seamlessly integrated digital display landscape. A standard 10.25-inch instrument cluster screen provides all critical driving information with crystal-clear graphics, while a generous 14.0-inch central infotainment screen serves as the hub for all multimedia, navigation, and vehicle settings. But for those who crave the ultimate digital immersion, the optional “Super Screen” takes things to another level. This adds a third 14.0-inch passenger screen, creating an expansive, ultra-wide digital canvas across the dashboard. Mercedes-Benz has ingeniously addressed privacy concerns here: the passenger screen automatically dims or turns off if the driver gazes at it for more than 1.3 seconds while the vehicle is in motion, ensuring minimal distraction and optimal safety.
At the heart of this digital experience is the enhanced MBUX Virtual Assistant. Thanks to advanced AI programming, MBUX is no longer just a voice command system; it’s a conversational partner with impressive short-term memory. You can fluidly ask it to “find the nearest fast charger with a coffee shop nearby” or “locate an Italian restaurant with vegetarian options and good reviews.” No more rigid command trees – MBUX understands context, learns your preferences, and responds like an intuitive co-pilot. The navigation system, powered by built-in Google Maps, goes a step further for EV models, offering intelligent cloud-based route and charge planning, factoring in real-time traffic, charger availability, and battery state to optimize your journey. This level of integrated AI and connectivity is a powerful selling point in 2025, elevating the user experience significantly.
Crucially, the GLB’s inherent boxiness translates directly into superior passenger space. Compared to the swoopy CLA, there’s a noticeable increase in headroom and legroom, further enhanced by a 2.4-inch longer wheelbase than the outgoing GLB model. This extended wheelbase directly benefits both the first and second rows, ensuring ample comfort for adults. Headroom receives a boost thanks to a standard panoramic sunroof, flooding the cabin with natural light. But for an added touch of magic, the optional “Sky Control” version of the sunroof allows you to switch the glass from clear to opaque in less than a second at the push of a button, offering instant privacy or glare reduction. At night, a stunning array of 158 three-pointed stars embedded within the glass softly illuminate, creating a truly enchanting ambiance.
As before, the 2027 GLB retains its unique selling proposition of offering an optional third row, transforming it into a versatile seven-seater. The second-row seats now slide even farther forward, greatly improving access to the rear-most seats. While an average-height adult can technically squeeze into the third row for short distances, it remains best suited for children or occasional use, emphasizing its utility as a flexible solution for growing families.
Cargo versatility is another strong suit. The GLB EV offers 19.1 cubic feet of space with the five-seat configuration, expanding significantly when the second row is folded. Even with the third row installed but folded, a generous 17 cubic feet is available. While specific figures for the third row up aren’t yet released, it’s safe to assume it will accommodate small bags or groceries, making it practical for daily family duties. The EV’s aforementioned 4.5-cubic-foot frunk further adds to its cargo prowess, offering secure storage separate from the main cabin. While hybrid cargo space figures are still pending, they are expected to be similar, minus the frunk, maintaining the GLB’s reputation as a highly practical luxury compact SUV.
