The two 1.6-litre turbocharged petrol engines provide either 120bhp or 154bhp, and because both deliver their peak pull at a lowly 1250rpm, they’re very flexible. A pair of 1.8-litre turbodiesels provide either 108bhp or 134bhp, and both have strong low-range muscle. None of these engines make the B-Class particularly quick, though. We haven’t driven the 168bhp 2.1-litre diesel yet.
Mercedes-Benz B-Class ride & handling
The B-Class has a distinctly firm ride that jitters you about on scruffy surfaces, whether you’re trundling along in town or blatting down the motorway. Sport models, with their lower suspension and bigger wheels, are even less forgiving. Tight body control and strong grip make the car feel secure in bends, but the inconsistently weighted steering ruins your fun.
Mercedes-Benz B-Class refinement
Considering the B-Class’ luxurious brief, you’d expect refinement to be better. There’s some wind noise on the motorway, and versions with big wheels kick up a fair amount of road noise. The engines get vocal as you pile on the revs, but they’re so flexible that you’ll rarely have to.
