INTRODUCTION
The Mercedes-Benz GLB 35 4MATIC, launched in 2023 following the X247 facelift, is the performance-oriented version of the GLB compact SUV. Built on the 2nd generation MFA platform (Mercedes-Benz Compact Architecture), it slots above the standard GLB models, offering a significant upgrade in power and handling. The GLB 35 aims to appeal to drivers who desire a practical, versatile vehicle with a sporty character, bridging the gap between mainstream compact SUVs and the more focused AMG models like the GLA 35. It’s available in both five and seven-seat configurations, providing flexibility for families or those needing occasional extra passenger capacity.
Powertrain & Engine Architecture
At the heart of the GLB 35 lies the M 260 2.0-liter inline-four cylinder engine, a member of Mercedes-AMG’s modular engine family. This engine produces 306 horsepower at 6,100 rpm and 295 lb-ft of torque between 2,500 and 4,000 rpm. A twin-scroll turbocharger with an intercooler enhances performance, while direct fuel injection ensures efficient combustion. The engine incorporates CAMTRONIC variable valve timing for optimized power delivery and fuel economy. Crucially, the GLB 35 features a 48V mild-hybrid system, adding a 14 hp electric motor that provides a boost during acceleration and enables a smoother start/stop function. This system contributes to improved efficiency and responsiveness. Power is transmitted to all four wheels via the AMG SPEEDSHIFT DCT 8G dual-clutch transmission, known for its rapid and precise gear changes. The transmission offers various driving modes, including a manual mode for greater driver control.
Driving Characteristics
The GLB 35 delivers a noticeably more engaging driving experience than the standard GLB models. The 306 hp engine and all-wheel-drive system enable brisk acceleration, with a 0-60 mph time of around 5.1 seconds. The AMG SPEEDSHIFT DCT 8G transmission provides quick and seamless gear changes, enhancing the sense of performance. While not as overtly aggressive as some dedicated performance SUVs, the GLB 35 offers a well-balanced ride, combining comfort with sporty handling. The suspension is tuned to provide a firm but controlled ride, minimizing body roll during cornering. The 4MATIC all-wheel-drive system ensures excellent traction in various conditions. The gear ratios are optimized for both acceleration and highway cruising, providing ample power throughout the rev range.
Equipment & Trim Levels
The GLB 35 comes generously equipped as standard. Key features include AMG-specific styling elements, such as a unique front grille, aggressive body kit, and quad exhaust outlets. Inside, the GLB 35 boasts sport seats upholstered in Artico leather and Dinamica microfiber, along with AMG-branded steering wheel and pedals. Standard technology includes the Mercedes-Benz User Experience (MBUX) infotainment system with a 10.25-inch touchscreen display, Apple CarPlay and Android Auto compatibility, and a suite of advanced driver-assistance systems. Optional extras include a panoramic sunroof, premium Burmester sound system, and a head-up display. The interior trim is typically finished with aluminum or carbon fiber accents, adding to the sporty ambiance.
Chassis & Braking
The GLB 35 features a specifically tuned chassis to handle the increased power and performance. The front suspension utilizes a McPherson strut design with a coil spring and anti-roll bar, while the rear suspension employs a multi-link setup with a stabilizer bar. The brakes consist of ventilated discs on all four wheels, providing ample stopping power. The AMG braking system, available as an option, offers even greater performance with larger rotors and calipers. The steering is a rack-and-pinion system with electric power assistance, providing precise and responsive steering feel.
Market Reception & Comparison
The GLB 35 has been generally well-received by automotive critics, praised for its blend of practicality, performance, and luxury. Compared to the standard GLB models, the 35 offers a significant upgrade in driving dynamics and overall refinement. It competes with other compact performance SUVs such as the BMW X2 M35i and the Audi SQ2. While the GLB 35 may not match the outright performance of some rivals, it offers a compelling package with its spacious interior, comfortable ride, and advanced technology. Fuel economy is respectable for a performance SUV, with combined WLTP figures ranging from 8.9 to 9.4 l/100 km.
Legacy
The M 260 engine, coupled with the AMG SPEEDSHIFT DCT 8G transmission, has proven to be a reliable and durable powertrain in other Mercedes-AMG applications. While long-term reliability data for the GLB 35 specifically is still emerging, the underlying technology is well-established. The GLB 35 is expected to hold its value reasonably well in the used car market, appealing to buyers seeking a sporty and practical compact SUV with a prestigious badge. Its combination of performance, versatility, and luxury positions it as a desirable option for enthusiasts and families alike.
