Electrifying Performance: The GLB EV Unpacked
The electrification of the automotive industry is undeniably the defining trend of our era, and the 2027 Mercedes-Benz GLB EV stands as a testament to Mercedes’ commitment to leading this charge. What was formerly known as the EQB has been seamlessly integrated into the GLB family, signaling a unified brand identity across powertrain types. When it arrives, we’ll see two distinct electric variants: the rear-wheel-drive GLB250+ with EQ Technology and the all-wheel-drive GLB350 4Matic with EQ Technology.
The base GLB250+ is far from basic. It’s projected to deliver a robust 268 horsepower and 247 lb-ft of torque, channeled through a sophisticated two-speed automatic transmission. This innovative gearbox is a crucial detail, expertly tuned for both exhilarating off-the-line acceleration and optimized efficiency during highway cruising – a balance that’s increasingly sought after in the luxury electric SUV segment. Mercedes-Benz estimates a 0-60 mph sprint in a brisk 7.3 seconds, which is more than ample for daily driving and provides confident merging capabilities.
For those demanding even greater performance and all-weather assurance, the GLB350 4Matic steps up considerably. This dual-motor setup adds a potent 107-hp front motor, while the rear motor is recalibrated to 242 hp, culminating in a combined output of 349 hp and an impressive 380 lb-ft of torque. The front motor operates on demand, engaging precisely when additional power for acceleration or enhanced traction is required, seamlessly blending efficiency with dynamic performance. This translates to a significantly quicker 0-60 mph time, projected at a rapid 5.4 seconds – putting it firmly in the performance luxury SUV category.
Powering these impressive drivetrains is an advanced 85-kWh battery pack, designed with 800-volt architecture. This high-voltage system is a game-changer for charging speeds, allowing the GLB EV to replenish its energy at up to 320 kW on compatible 800-volt DC fast chargers. Mercedes-Benz touts an ability to add 162 miles of range in a mere 10 minutes – a pivotal factor in alleviating range anxiety for busy professionals and families alike. While the WLTP cycle suggests a range of 323 to 392 miles, based on my observations of European vs. EPA estimates, we can anticipate official U.S. figures to be slightly more conservative, likely settling in the mid-to-high 200s or low 300s, which is still highly competitive.
Crucially, the 2027 GLB EV introduces a built-in DC converter, a feature that sets it apart from its CLA sibling. This means hassle-free charging on older 400-volt infrastructure without the need for cumbersome adapters, significantly broadening its charging accessibility. Furthermore, Mercedes-Benz’s adoption of the Tesla-designed North American Charging Standard (NACS) port is a major win for consumers. This allows direct access to the vast and reliable Tesla Supercharger network, arguably the most extensive fast-charging ecosystem in North America. For those who still frequent CCS-type chargers, a convenient adapter will also be provided, ensuring maximum flexibility. This multi-faceted approach to charging infrastructure signals a deep understanding of the practicalities of EV ownership, making the GLB EV an exceptionally versatile and future-ready choice for the discerning driver. The marriage of compelling performance, rapid charging, and extensive network compatibility ensures the GLB EV is not just a luxury electric SUV, but a truly practical one.
The Best of Both Worlds: GLB Hybrid Dynamics
While the electric revolution undeniably garners significant attention, Mercedes-Benz understands that a significant portion of the luxury automotive market still values the inherent flexibility and range of a hybrid powertrain. For this reason, the 2027 GLB will also offer a sophisticated hybrid variant, expected to follow the EV’s market introduction by several months. While Mercedes has remained tight-lipped on specific details for the GLB Hybrid, drawing parallels with the recently unveiled CLA Hybrid provides us with a highly educated forecast.
It’s reasonable to anticipate that the GLB Hybrid will share its core drivetrain with the CLA, a system engineered for both robust performance and impressive fuel efficiency. This likely involves a 1.5-liter turbocharged inline-four engine, a marvel of modern internal combustion, utilizing the highly efficient Miller combustion cycle. This engine isn’t just paired with, but seamlessly integrated into, an advanced eight-speed dual-clutch automatic transmission that also houses a potent 30-horsepower electric motor. This synergistic setup is projected to deliver a combined output of approximately 208 horsepower and a healthy 280 lb-ft of torque. In the slightly lighter CLA sedan, this powertrain enables a respectable 0-60 mph sprint in an estimated 7.1 seconds; the GLB, while a bit larger, should offer comparable spirited performance suitable for a premium compact SUV.
A key advantage of this integrated hybrid system is its ability to disconnect the engine entirely when not needed. An additional clutch within the gearbox facilitates pure-EV driving at lower speeds or during coasting, significantly boosting urban fuel economy and reducing emissions. For the driver, the experience is refined and intuitive, with manual gear changes accessible via a simple push-pull motion of the column shifter – a characteristic Mercedes-Benz touch that emphasizes driver engagement.
Furthermore, the GLB Hybrid will cater to diverse driving conditions by offering both front-wheel drive and the proprietary 4Matic all-wheel-drive system. My professional assessment suggests that, similar to the CLA Hybrid 4Matic, the GLB Hybrid’s all-wheel-drive system will be intelligent and adaptive, disconnecting the rear axle when not required for traction or performance, thus conserving fuel. However, when conditions demand, up to 40 percent of the power can be dynamically routed to the rear wheels, providing enhanced grip and stability on slick surfaces or during spirited driving. This thoughtful engineering ensures that the GLB Hybrid provides an optimal balance of power, efficiency, and all-weather capability, making it a compelling choice for luxury SUV buyers who aren’t quite ready to go fully electric but demand cutting-edge hybrid technology. It’s a pragmatic yet premium solution that ensures broad appeal in a competitive landscape.

A Mercedes-Benz is defined not just by its engine or motor, but by the holistic driving experience it delivers. The 2027 GLB elevates this philosophy with a suite of features designed to enhance both comfort and capability, distinguishing itself in the premium compact SUV segment.
For drivers who occasionally venture off the beaten path, or simply navigate challenging weather conditions, the optional 4Matic all-wheel-drive models come equipped with a specialized Terrain driving mode. This mode intelligently recalibrates the vehicle’s traction control, throttle response, and transmission mapping to maximize grip and stability on loose surfaces like gravel or snow. It’s a thoughtful addition that underscores the GLB’s versatility beyond urban confines. Adding another layer of utility, if specified with the optional 360-degree camera system, drivers gain access to the innovative “transparent hood” feature. This ingenious system utilizes the center screen to project a real-time view of the terrain directly beneath the front of the car, effectively making the hood “invisible” and allowing drivers to accurately place wheels over obstacles – a feature typically found in much larger, more rugged SUVs, now refined for the compact luxury class.
Ride quality is paramount in a Mercedes, and the 2027 GLB offers adaptive dampers as an optional upgrade. These continuously variable shock absorbers adjust their firmness in milliseconds based on road conditions and driver input, providing a sublime balance between supple comfort and dynamic control. While they require opting for the larger 20-inch wheels, the enhanced ride sophistication is a worthwhile investment for discerning drivers. For those preferring a slightly more understated aesthetic or desiring increased sidewall for rougher roads, 18- and 19-inch wheel options are also available, maintaining the GLB’s elegant stance.
This blend of intelligent off-road assistance, sophisticated ride tuning, and thoughtful wheel choices demonstrates Mercedes-Benz’s commitment to crafting a luxury SUV that isn’t just about appearances, but about delivering a refined and capable driving experience tailored to a variety of lifestyles.
Interior Reimagined: Space, Tech, and Unparalleled Comfort
Stepping inside the 2027 Mercedes-Benz GLB reveals an interior that is, predictably, a masterclass in modern luxury and cutting-edge technology, largely mirroring the avant-garde design language introduced in the new CLA. From my extensive experience assessing automotive interiors, Mercedes-Benz consistently pushes boundaries, and the GLB is no exception. Dominating the dashboard is the familiar, upright aesthetic, anchored by a standard 10.25-inch digital instrument cluster and a expansive 14.0-inch central infotainment screen. For the true tech enthusiast, Mercedes’ optional “Super Screen” takes center stage, adding an additional 14.0-inch passenger display, transforming the cabin into a truly immersive digital cockpit. Mercedes has even built in clever privacy features; the passenger screen intelligently dims if the driver’s gaze lingers for more than 1.3 seconds while the vehicle is in motion, ensuring minimal distraction.
The MBUX Virtual Assistant has been dramatically enhanced with advanced AI programming, now boasting conversational capabilities and even short-term memory. This means interacting with the vehicle is more intuitive and less command-based. Instead of rigid commands, you can converse naturally, asking it to “find the nearest EV charging station with a coffee shop” or “locate an Italian restaurant with vegetarian options nearby.” The navigation system, powered by integrated Google Maps, provides not just directions but cloud-based EV route and charge planning, intelligently factoring in battery status, terrain, and charger availability – a crucial feature for the electric variants.
Where the GLB truly differentiates itself from its sleeker CLA counterpart, and even its predecessor, is in its generous interior volume. The boxy silhouette, a GLB hallmark, translates directly into exceptional passenger space. Mercedes-Benz has further amplified this with a 2.4-inch longer wheelbase, directly benefiting legroom in both the first and second rows. Headroom, too, sees a significant improvement, thanks to the standard panoramic sunroof that bathes the cabin in natural light. For an added touch of celestial luxury, the optional Sky Control version of the panoramic sunroof allows occupants to switch the glass from transparent to opaque in under a second with a simple button press. At night, a truly magical touch: 158 tiny three-pointed stars are embedded within the glass, illuminating the cabin with a subtle, starry glow – an exquisite detail that underscores Mercedes’ commitment to sensory luxury.
A key selling point for the GLB has always been its optional third-row seating, a rare find in the compact luxury SUV segment, and this continues for 2027. While it allows for seven-passenger capacity, it’s essential to set realistic expectations. The second-row seats now slide further forward, improving access to the very back, making it more convenient for smaller passengers. As an expert, I’d still recommend reserving the third row primarily for children or for occasional, short-distance adult use, as an average-height adult would likely find it a bit snug.
Cargo versatility remains a strong suit. The GLB EV offers a practical 19.1 cubic feet of cargo space with the third row folded down (five-seat configuration), decreasing slightly to 17 cubic feet when the third row is installed but stowed. While cargo capacity with the third row actively in use isn’t yet specified, expect it to accommodate smaller items like a couple of duffel bags. A significant advantage for the EV is its substantial 4.5-cubic-foot frunk (front trunk), which provides secure storage and is notably larger than that found in a Tesla Model Y – a true differentiator. Hybrid cargo space is anticipated to be similar to the EV’s rear compartment (minus the frunk), though official figures are still pending. This intelligent use of space, coupled with advanced technology and luxurious appointments, ensures the 2027 GLB’s interior is as functional as it is inviting.

It aims to dominate the premium compact luxury SUV segment, offering a unique blend of three-row versatility, advanced powertrain options, and cutting-edge technology. In a market increasingly populated by electric and hybrid contenders, the GLB’s dual-pronged approach with both pure EV and efficient hybrid offerings ensures broad appeal, targeting eco-conscious buyers alongside those seeking maximum range and flexibility. Competitors will undoubtedly take notice of its sophisticated MMA platform and NACS charging integration.
Given that U.S. pricing is still over a year away from its official announcement, we rely on educated estimates informed by Mercedes-Benz’s recent pricing strategies. The company has shown a tendency to maintain relative consistency, even with significant model updates. Therefore, my assessment is that we can anticipate a modest increase over current GLB and EQB models. This would likely place the starting price for the 2027 GLB EV (successor to the EQB) in the neighborhood of $55,000. The GLB Hybrid, while offering exceptional efficiency, typically falls at a slightly more accessible price point than its pure-electric counterpart, thus an estimated starting price of approximately $48,000 seems reasonable. These figures position the GLB as a highly attractive proposition, offering compelling value within the luxury compact SUV space, especially considering its advanced technology, expanded space, and dual-powertrain strategy. Mercedes-Benz is clearly aiming to provide a top-tier luxury experience without venturing into the exorbitant price tags of larger, full-size SUVs.
