Powertrain & Engine Architecture
The GLB 350 4MATIC EQ Technology utilizes a dual-motor, all-wheel-drive (AWD) powertrain. A synchronous electric motor drives the front axle, producing 109 horsepower, while a more powerful synchronous motor at the rear delivers 272 horsepower. Combined, these motors generate a system output of 354 horsepower and 515 Nm (379.84 lb.-ft.) of torque. The powertrain is powered by an 85 kWh lithium-nickel-manganese-cobalt oxide (Li-NMC) battery pack located under the vehicle floor, contributing to a low center of gravity and improved handling. The vehicle employs a two-speed automatic transmission, optimizing efficiency and performance across a range of driving conditions. The recuperation system, capable of up to 200 kW, allows for efficient energy recovery during deceleration, extending the vehicle’s range.
Driving Characteristics
The GLB 350 EQ delivers brisk acceleration, achieving 0-60 mph in approximately 5.2 seconds. The instant torque characteristic of electric motors provides responsive acceleration in all situations. The dual-motor AWD system ensures excellent traction and stability, particularly in adverse weather conditions. The two-speed transmission allows for strong off-the-line acceleration in first gear, while second gear provides efficient cruising at highway speeds. Compared to potential future AMG-tuned electric GLB variants, the 350 EQ prioritizes a balance between performance and efficiency, offering a comfortable and refined driving experience.
Equipment & Trim Levels
The GLB 350 4MATIC EQ Technology comes standard with a comprehensive suite of features, including Mercedes-Benz’s MBUX infotainment system with a touchscreen display, advanced driver-assistance systems (ADAS) such as adaptive cruise control and lane-keeping assist, and premium interior materials. Interior upholstery typically consists of high-quality synthetic leather or available genuine leather options. Optional extras include a panoramic sunroof, upgraded sound system, and head-up display. The dashboard configuration is modern and minimalist, emphasizing the vehicle’s high-tech character.
Chassis & Braking
The GLB 350 EQ features an independent McPherson strut front suspension and an independent multi-link rear suspension, both incorporating coil springs and anti-roll bars. This setup provides a comfortable ride and responsive handling. The braking system utilizes disc brakes on all four wheels, coupled with ABS (Anti-lock Braking System) and electronic stability control. The vehicle’s relatively low center of gravity, due to the battery pack’s placement, contributes to reduced body roll and improved cornering stability.
Market Reception & Comparison
The GLB 350 4MATIC EQ Technology has been generally well-received by automotive critics, praised for its spacious interior, comfortable ride, and impressive electric range (521-614 km / 323.73 – 381.52 mi WLTP). Compared to other electric SUVs in its class, such as the Tesla Model Y and BMW iX1, the GLB 350 EQ offers a more traditional luxury experience with a focus on refinement and practicality. Its energy consumption of 15.9-18.6 kWh/100 km (25.59 – 29.93 kWh/100 mi) is competitive within the segment.
Legacy
As a relatively new model, the long-term reliability of the GLB 350 EQ powertrain is still being established. However, Mercedes-Benz has a strong reputation for building durable and reliable vehicles. The Li-NMC battery technology is widely used in electric vehicles and has a proven track record. In the used car market, the GLB 350 EQ is expected to hold its value well due to its desirable features, brand prestige, and growing demand for electric vehicles. The vehicle represents a key step in Mercedes-Benz’s transition to an all-electric future, and its success will likely influence the development of future electric SUVs from the brand.
