2026 Mercedes-Benz GLB Model Review

The 2026 GLB 250 4MATIC® SUV is powered by a refined 2.0L inline-4 turbo engine enhanced by a 48-volt mild-hybrid system. This advanced powertrain delivers 221 horsepower and 258 lb-ft of torque, ensuring a responsive and efficient drive through the Glendale area. The 8G-DCT 8-speed dual-clutch automatic transmission provides rapid, smooth gear changes, allowing the GLB to accelerate from 0 to 60 mph in a swift 6.9 seconds.

The integrated mild-hybrid technology features a belt-driven starter-generator that can provide an additional 13-horsepower boost for quick acceleration and allows for fuel-saving coasting. For local drivers, this translates to an estimated fuel economy of up to 25 mpg in the city and 33 mpg on the highway, beating several competitors in its class.

The cabin of the 2026 GLB is a sanctuary of modern architecture and high-quality materials. Standard MB-Tex upholstery offers a luxurious feel, while available leather seating and 64-color LED ambient lighting allow Glendale owners to personalize their environment. The GLB is one of the few compact SUVs to offer an optional third-row seat, increasing passenger capacity from five to seven for growing families.

Cargo versatility is a core strength of the GLB design. It provides 22.0 cubic feet of space behind the second row, which expands to a cavernous 62.0 cubic feet when the rear seats are folded flat. The low lift-in height and standard power liftgate with available HANDS-FREE ACCESS® make loading groceries or sports gear at Mayfair Mall effortless.

The 2026 GLB is engineered to handle the unpredictable Wisconsin weather with confidence. The available 4MATIC® variable all-wheel drive system monitors traction in real-time, instantly adjusting the torque split between front and rear wheels to maximize stability on rain-slicked or snowy Milwaukee roads. When properly equipped, the GLB offers a maximum towing capacity of up to 3,500 pounds, providing surprising utility for a compact SUV.

For light off-road adventures, the GLB includes an Off-Road Engineering Package as part of the 4MATIC® system. This package adds a specialized driving mode that optimizes power delivery and braking, along with an off-road display in the MBUX® system that shows steering angle and tilt to help you navigate uneven terrain.

The exterior of the 2026 GLB features an upright, muscular stance that pays homage to the legendary G-Class. The front is highlighted by full LED headlamps and a striking grille design, while short overhangs emphasize its athletic proportions. Milwaukee owners can choose from various wheel options, ranging from standard 18-inch twin 5-spoke designs to available 20-inch AMG® multispoke wheels in black when opting for the Night Package.

The 2026 GLB features the latest generation of the Mercedes-Benz User Experience (MBUX®), which integrates dual 10.25-inch high-resolution displays. This intuitive system uses artificial intelligence to learn driver preferences and responds to natural-language voice commands via "Hey Mercedes" activation. Standard wireless Apple CarPlay® and Android Auto™ ensure seamless smartphone integration for every Milwaukee commute.

Safety is fundamental to the 2026 GLB, which comes standard with a comprehensive suite of driver-assist technologies. This includes Active Brake Assist®, Blind Spot Assist®, and ATTENTION ASSIST®, which monitors for signs of driver fatigue during long trips. The standard PARKTRONIC® with Active Parking Assist helps you navigate tight street parking in downtown Milwaukee with ease.

While official 2026 ratings are finalized, the GLB series has historically performed exceptionally well in safety evaluations. Available upgrades like Active Distance Assist DISTRONIC® and PRE-SAFE® PLUS provide additional layers of protection by preparing the cabin for potential impacts from the rear or sides.

The GLB 250 SUV serves as the foundational model, featuring the 221-hp mild-hybrid engine and front-wheel drive. It includes 18-inch wheels, heated power front seats with memory, and the dual-screen MBUX® system as standard equipment. This trim is ideal for drivers who prioritize urban efficiency and the hallmark luxury of Mercedes-Benz.

The GLB 250 4MATIC® SUV adds the permanent all-wheel drive system and the Off-Road Engineering Package. It shares all the luxury features of the standard GLB 250 while providing the extra traction and stability required for Wisconsin's winter months. This is the premier choice for local drivers who require all-weather confidence.
