The Mercedes-Benz GLB (internal code X247) is a compact luxury crossover SUV introduced in 2019. Positioned between the GLA and the GLC, it utilizes the MFA2 front-wheel-drive architecture but distinguishes itself with a boxy, utilitarian design inspired by the G-Class and the larger GLS. Its major selling point in the premium compact segment is the optional third row of seats, making it a 7-seater (though strictly for children or short trips). The GLB received a mid-life facelift (Phase 2) in late 2023, introducing 48V mild-hybrid technology to its petrol engines, updated LED light signatures, and the latest generation of the MBUX infotainment system.
The Mercedes-Benz GLB is a highly pragmatic choice in the premium compact SUV segment. It successfully blends the footprint of an A-Class with the practicality of a much larger vehicle. Mechanically, it is generally sound, with the Renault-sourced 1.3L petrol and Mercedes' own 2.0L diesel proving reliable over time. However, buyers should be prepared for typical modern Mercedes quirks: occasional electronic glitches with the MBUX system and interior plastics that can rattle over time. If you need a premium family hauler and occasionally carry extra kids, the GLB is an excellent choice. For high mileage, the GLB 200 d is the sweet spot; for mixed use, the GLB 200 petrol is more than adequate.
