The GLB250+, serving as the entry point into the electric GLB range, promises a compelling blend of power and impressive efficiency. Its single electric motor, strategically placed on the rear axle, generates a robust 268 horsepower and 247 pound-feet of instant torque. For a vehicle in the luxury compact SUV class, these figures translate into brisk acceleration, with Mercedes-Benz estimating a 0-60 mph sprint in a respectable 7.3 seconds. This RWD setup not only provides a refined driving dynamic but also optimizes range, making it an ideal choice for urban commutes and longer journeys alike.
For those seeking more exhilarating performance and enhanced all-weather capability, the GLB350 steps up considerably. Featuring a dual-motor, all-wheel-drive configuration, this variant unleashes a formidable 349 horsepower and 380 pound-feet of torque. The additional motor and increased power dramatically shrink the 0-60 mph time to a swift 5.4 seconds, positioning the GLB350 as a truly sporty contender within its segment. The inclusion of a two-speed transmission on the rear axle in both electric models is a notable engineering detail, optimizing power delivery across various speed ranges, which is a sophisticated touch rarely seen in this class.
Both the GLB250+ and GLB350 share a common high-capacity 85 kWh usable nickel-manganese-cobalt (NMC) battery. This advanced battery chemistry is crucial for balancing energy density, power output, and long-term durability, all vital considerations for a premium electric vehicle. While the GLB350 offers superior performance, the GLB250+ takes the crown for range, with WLTP estimates spanning an impressive 337 to 392 miles. For the U.S. market, applying typical EPA conversion factors, this likely translates to a real-world range of approximately 286 to 333 miles—a highly competitive figure that should alleviate range anxiety for most drivers. The GLB350, with its performance-oriented setup, still delivers an excellent estimated EPA range of 275 to 325 miles, proving that enhanced power doesn’t necessitate significant compromise on usability.
Charging capabilities are equally crucial for any compelling EV, and the 2027 GLB doesn’t disappoint. It supports AC charging at up to 9.6 kilowatts, allowing for convenient overnight charging at home or at public Level 2 stations. More impressively, the GLB’s DC fast-charging capacity reaches a blistering 320 kilowatts. This capability places it among the fastest-charging EVs available, meaning drivers can add significant range during short stops, turning what used to be a lengthy ordeal into a quick coffee break. This level of charging speed is critical for making long-distance EV travel genuinely practical and seamless, a testament to Mercedes-Benz’s focus on user experience.

While the electric GLB takes center stage, Mercedes-Benz intelligently recognizes that not every luxury buyer is ready for a full transition to electric. Therefore, a sophisticated hybrid GLB variant will join the lineup shortly after the EV launch, offering a compelling bridge technology. This hybrid model is expected to heavily borrow its powertrain from the innovative CLA220 hybrid, indicating a well-tested and efficient setup.
At its core, this hybrid system combines a fuel-efficient 1.5-liter Miller-cycle four-cylinder gasoline engine with a 27-horsepower electric motor, seamlessly integrated into an eight-speed dual-clutch automatic transmission. A compact 1.3-kWh lithium-ion battery supports the electric motor. The combined output for this gas-electric powertrain is a respectable 188 horsepower. This configuration is designed for optimal efficiency, with the electric motor providing pure-electric propulsion for short distances, particularly useful in urban environments or stop-and-go traffic. While the pure-electric speed is capped at around 60 mph, it significantly enhances fuel economy and refines the driving experience by providing silent, emissions-free operation at lower speeds. This GLB hybrid presents an ideal solution for those who desire reduced fuel consumption and a smaller carbon footprint without the need for dedicated charging infrastructure or long EV ranges.
Interior Evolution: Space, Comfort, and Digital Immersion
The GLB’s reputation for practicality and ingenious packaging is not just maintained but significantly enhanced for its second generation. The 2027 model boasts larger exterior dimensions, carefully sculpted to maximize interior space without sacrificing its distinct identity. The new GLB body is 3.9 inches longer, 1.1 inches wider, and 0.9 inch shorter than its predecessor, with a substantial 2.4-inch increase in wheelbase. These seemingly modest increments translate into meaningful gains inside the cabin.
Crucially, second-row legroom expands by an impressive 2.7 inches, transforming the rear passenger experience and making the GLB even more appealing for families or those who frequently carry adult passengers. While third-row headroom sees a minor reduction of a tenth of an inch, the continued availability of both five- and seven-seat configurations ensures the GLB retains its unique versatility. Improvements in practicality extend to larger rear door openings and an increased range of movement for the second-row seats, significantly easing ingress and egress to the third row—a common challenge in compact seven-seaters. Mercedes-Benz has clearly listened to feedback, optimizing user experience for all occupants.
Aesthetically, the exterior design, while retaining the familiar squared-off silhouette, evolves to align with Mercedes-Benz’s contemporary design language. The front fascia adopts the elegant “unibrow-and-big-grille” styling seen on the new CLA-Class, lending a more sophisticated and cohesive look. The rear features a modern, width-spanning LED lighting array that provides a distinctive signature, especially at night. In person, the new GLB feels more substantial and purposeful, with a particularly upright and chunky D-pillar that subtly enhances its robust character while hinting at its generous interior volume. This evolution strikes a perfect balance between preserving the GLB’s beloved functionality and elevating its luxury appeal.
