It’s a rare occurrence that the often bulbous, inflated proportions of an MPV – even those at the smaller end of the size spectrum – lend themselves to visually appealing design. The original B-Class wasn’t a looker by any means, but fast forward to 2019 and this W247 model could just about pass for handsome.
From a distance, its aesthetic relationship to the lower, sleeker A-Class is readily apparent, but closer inspection reveals notable stylistic differences. The larger, more rounded headlights of the B-Class complement its augmented proportions and lend the compact MPV a gentler front end that’s not quite as pointed as that of its range-mate. A comparatively gentler tail-light design, meanwhile, helps to minimise the visual impact of its taller roofline.
Beneath the familial exteriors, the relationship between the two is as close as ever. Their shared MFA2 architecture means that, for the most part, the A-Class and B-Class are dimensionally identical. Both are 4419mm long and 1796mm wide, with a shared wheelbase of 2729mm.
Height is, rather obviously, the main point of difference; the boxier roofline of the B-Class means it stands 122mm taller, at 1562mm. The introduction of this new architecture made the A-Class one of the largest cars in its segment – a possible point of contention for buyers after a compact hatch. In relation to the B-Class, though, this dimensional increase should add to its practical appeal.
