Spied here undergoing a final round of tests ahead of a planned start to UK sales in early 2019, the five-seat MPV will join the recently introduced fourth-generation A-Class hatchback as well as standard and long-wheelbase versions of the new A-Class Saloon. These are part of an expanded line-up that will also include second-generation versions of the CLA, CLA Shooting Brake and GLA, as well as the new GLB, in showrooms by the end of next year.
The new B-Class, known under the internal codename W247, retains the one-box silhouette of its predecessors, but in a much smoother form that reflects Mercedes' latest design lineage. The heavy structuring and taut surfacing evident in the sides of today’s second-generation model gives way to a simpler and largely unadorned treatment.
The BMW 2 Series Active Tourer rival also adopts the so-called 'predator face' of the A-Class, giving it greater visual impact at the front. At the rear, its tailgate is more sharply angled than before.
