For the consumer, this means the 2027 Mercedes-Benz GLB isn’t just a bigger CLA; it’s a versatile vehicle that inherits the sedan’s sophisticated ride quality and nimble handling, then adapts it for an SUV body. This strategic engineering move ensures that despite its boxier, more capacious exterior, the GLB retains a distinctly “Mercedes” feel on the road, distinguishing it in a crowded compact luxury SUV market.
Electrifying Performance: The GLB EV Unleashed
The most anticipated variants of the 2027 GLB are undoubtedly its all-electric counterparts, poised to spearhead Mercedes-Benz’s electric vehicle future. Building on the legacy of the EQB, which the new GLB EV effectively succeeds, these models are designed to redefine GLB electric range and charging convenience. Mercedes-Benz is rolling out two primary EV configurations at launch: the rear-wheel-drive GLB250+ with EQ Technology and the all-wheel-drive GLB350 4Matic with EQ Technology.
The base GLB250+ will impress with a robust 268 horsepower and 247 lb-ft of torque, delivered through a sophisticated two-speed automatic transmission. This setup is engineered for that instant, satisfying acceleration off the line while maintaining exceptional efficiency during highway cruising. For those craving more exhilarating performance and enhanced traction, the GLB350 4Matic ups the ante significantly. It integrates an additional 107-hp front motor, working in concert with a slightly detuned 242-hp rear motor to achieve a formidable combined output of 349 hp and 380 lb-ft. This intelligent all-wheel-drive system activates the front motor precisely when needed, ensuring optimal power delivery and grip in diverse driving conditions.
Performance figures are equally compelling. Mercedes-Benz projects the base EV to hit 60 mph in a brisk 7.3 seconds, while the dual-motor 4Matic variant shaves that down to a spirited 5.4 seconds. These figures position the GLB EV as a competitive player in the performance electric SUV segment, offering more than enough grunt for daily commutes and spirited weekend drives.
Range anxiety, a persistent concern for many EV adopters, is comprehensively addressed. The 2027 GLB EV is equipped with an 85-kWh battery, estimated to deliver between 323 and 392 miles on a full charge, based on the WLTP test cycle. While we anticipate official U.S. EPA figures to be slightly more conservative, this still projects a highly competitive GLB electric range that will easily accommodate most drivers’ needs.
The charging infrastructure is where Mercedes-Benz truly demonstrates its automotive innovation 2027 leadership. The GLB EV features an 800-volt battery architecture, enabling blisteringly fast charging speeds of up to 320 kW on compatible high-speed chargers. This translates to adding an impressive 162 miles of range in just 10 minutes – a game-changer for long-distance travel. Crucially, and unlike some other MMA platform vehicles, the GLB comes with a built-in DC converter. This thoughtful inclusion allows seamless charging on older 400-volt chargers without the need for cumbersome adapters, greatly enhancing accessibility.

Following the EV’s initial rollout, the GLB Hybrid will make its debut, offering a compelling blend of fuel efficiency and robust performance. While specific details remain under wraps, industry insights and the shared CLA platform allow us to make highly educated guesses about its powertrain.
We expect the GLB Hybrid to mirror the sophisticated drivetrain found in the new CLA Hybrid. This setup features a highly efficient 1.5-liter turbocharged inline-four engine, utilizing the advanced Miller combustion cycle to maximize thermal efficiency. This engine is seamlessly paired with an eight-speed dual-clutch automatic transmission that cleverly integrates a 30-hp electric motor. The combined output for this potent hybrid SUV performance package is anticipated to be around 208 hp and 280 lb-ft of torque. This configuration propelled the smaller CLA sedan to 60 mph in an estimated 7.1 seconds, and we expect similar, if not slightly adjusted, figures for the GLB Hybrid.
A notable feature of this advanced gearbox is an additional clutch that allows the engine to be fully disconnected for pure EV driving at lower speeds or for fuel-saving coasting. This provides excellent flexibility and contributes to overall efficiency, a key factor for those considering a Mercedes GLB Hybrid. Shifting gears manually, for those who enjoy a more engaged driving experience, will be intuitively managed via the column shifter – a quick push forward for an upshift, and a pull back for a downshift.
Just like its EV counterpart, the GLB Hybrid will offer both front-wheel-drive and 4Matic all-wheel-drive configurations. In the 4Matic hybrid models, we anticipate the intelligent system will selectively disengage the rear axle when not required, optimizing fuel economy without compromising traction or performance when conditions demand it. Up to 40 percent of the power can be dynamically sent to the rear wheels, providing confident handling in various scenarios.
Beyond the Pavement: Capability and Control
While the GLB isn’t designed for extreme off-roading, its versatility extends beyond urban jungles. All-wheel-drive models come equipped with a dedicated Terrain driving mode, finely tuned to maximize traction on loose surfaces – perfect for gravel roads or light snow. This feature is a subtle nod to the adventurous spirit of SUV ownership, ensuring that the GLB is always All Road Ready-ish for whatever the journey throws its way.
For those who opt for the enhanced 360-degree camera system, Mercedes-Benz introduces an ingenious “transparent hood” feature. Utilizing the central infotainment screen, this system projects a real-time view of the ground directly beneath the front of the car, effectively making the hood “invisible.” This is invaluable for navigating tight trails, parking in tricky spots, or simply keeping an eye on obstacles immediately ahead – an advanced driver assistance systems Mercedes innovation that truly benefits the user.
Drivers will have a choice of wheel sizes, with 18- and 19-inch options available as standard. For those seeking enhanced dynamics and a sportier aesthetic, optional adaptive dampers can be selected, though they require the larger 20-inch wheels. These adaptive dampers continuously adjust to road conditions, providing a smoother ride over rough terrain and sharper handling during spirited driving, further enhancing the Mercedes-Benz GLB’s overall driving appeal.
Sanctuary of Innovation: Inside the 2027 GLB
Step inside the 2027 GLB, and the shared lineage with the new CLA becomes immediately apparent, but with a crucial difference: space. The interior design ethos is unmistakably Mercedes-Benz, characterized by a contemporary, upright dashboard and a minimalist yet luxurious aesthetic. Standard features include a vibrant 10.25-inch instrument cluster screen and a generously sized 14.0-inch central infotainment display, both powered by the latest iteration of the MBUX system.
For the ultimate in digital immersion, the optional “Super Screen” takes center stage, adding an additional 14.0-inch passenger screen. This cutting-edge setup creates a truly immersive cockpit, offering unparalleled customization and access to entertainment and information. Mercedes-Benz has even implemented a clever safety feature: the passenger screen automatically dims if the driver’s gaze lingers for more than 1.3 seconds while the vehicle is in motion, preventing distraction – a smart application of high-tech SUV interior design.
The heart of the GLB’s digital experience is the enhanced MBUX Virtual Assistant. Thanks to advanced AI programming, this assistant now boasts conversational capabilities and even short-term memory. This means interacting with your car is more natural and intuitive than ever. Instead of rigid command structures, you can now casually ask it to “find the nearest EV charger with fast charging capability” or “locate a highly-rated vegan restaurant nearby,” and it will intelligently respond, remembering previous requests within the conversation. This next-gen MBUX system also seamlessly integrates built-in Google Maps for navigation, offering cloud-based EV route and charge planning, ensuring optimal journey management for electric family SUV owners.
But where the GLB truly shines against its sedan sibling is in its spaciousness. The boxier profile, coupled with a significant 2.4-inch increase in wheelbase, translates to vastly improved legroom for both first and second-row passengers. Furthermore, a standard panoramic sunroof (and an even more spectacular optional Sky Control version) dramatically enhances headroom and interior ambiance. The Sky Control sunroof is a technological marvel, allowing occupants to switch the glass from transparent to opaque in under a second with a simple push of a button. At night, 158 subtly embedded three-pointed stars illuminate within the glass, creating a truly magical atmosphere – a testament to Mercedes panoramic sunroof innovation.
The GLB’s enduring appeal, especially for growing families, remains its optional third row, transforming it into a bona fide 7-seat Mercedes SUV. To improve access to this crucial rear space, the second-row seats now slide further forward. While an average-height adult can technically fit in the third row for short trips (albeit with some slouching), it’s undeniably best suited for children or smaller adults, especially for extended journeys. This feature is a significant differentiator in the compact luxury SUV market, making the GLB a prime candidate for GLB third row seating review comparisons.
Practicality Redefined: Cargo and Family Living
In the realm of GLB cargo space, the 2027 model continues to impress, reinforcing its reputation as a highly practical luxury vehicle. For the EV variants, you’ll find a generous 19.1 cubic feet of cargo room with the second row in use. With the third row installed but folded flat, that space adjusts slightly to 17 cubic feet, still ample for daily errands. While specific figures for cargo space with the third row actively in use aren’t yet released, expect it to be suitable for essentials like a large duffel bag or grocery haul.
A notable advantage of the GLB EV is its substantial 4.5-cubic-foot frunk (front trunk). This “extra” storage space is larger than what you’d find in popular competitors like the Tesla Model Y, providing a secure and convenient place for charging cables, smaller bags, or items you want to keep separate from the main cargo area. For the hybrid models, we anticipate similar cargo dimensions behind the second row, though the frunk will likely not be present due to engine components. This focus on maximizing utility underscores the GLB’s role as a luxury electric vehicle designed for real-world family life. The balance between a compact footprint and genuine utility makes the GLB a standout for electric family SUV shoppers.
