About the Mercedes-Benz GLB
AI-generatedThe Mercedes-Benz GLB is a compact seven-seat SUV that arrived in the UK market in 2019, offering a practical and premium alternative to the brand's smaller GLA. Built on the same platform as the A-Class, the GLB provides a boxy, upright design reminiscent of the larger G-Class, maximising interior space and delivering genuine seven-seat capability in a relatively compact footprint. Despite its compact dimensions, the GLB offers impressive practicality with a flexible interior, generous boot space, and optional third-row seating that can accommodate adults for shorter journeys. Available with a range of petrol and diesel engines, plus plug-in hybrid variants (GLB 250e), the GLB combines Mercedes' latest MBUX infotainment system with a comfortable ride and strong build quality. While not the most engaging to drive compared to sportier rivals, it excels as a premium family SUV with excellent refinement, a commanding driving position, and the prestige of the three-pointed star. The GLB occupies a unique position in the Mercedes lineup, bridging the gap between the GLA and the larger, more expensive GLE.

Did You Know?
Did You Know?
The GLB is the only compact Mercedes-Benz SUV to offer seven seats as standard or optional equipment, depending on the market.
Despite being smaller than a Range Rover Evoque in length, the GLB offers more interior space thanks to its tall, boxy design.
The GLB nameplate references Mercedes' heritage, with 'GL' denoting an SUV (Geländewagen) and 'B' indicating its compact size.
The third-row seats in the GLB are actually usable by adults up to 1.68m tall, unlike many rivals where they're only suitable for children.
