Seats are comfortable with ample legroom and headroom in the front and rear. The rear bench is fine for two adults – although three will be a push – and there are up to 1547 litres of luggage space on offer if you push the rear bench down.
Mechanically, though, the refinement of this B-class still needs some work. The 2.0-litre diesel engine is noisy at idle, and intrudes into the cabin on the move. There’s also a significant level of wind noise at motorway speeds.
For all its noise, though, the engine does at least offer decent levels of power. Mercedes says the B 200 CDI Sport can reach 62mph from rest in 9.8sec, and in practice, getting up to speed is never an issue.
The seven-speed automatic transmission fitted to our test car is capable but seems slow to change gears under load. As usual, it also offers the choice of Sport, Eco or Manual modes, the latter operated via steering wheel-mounted paddles.
Official fuel economy figures suggest this B-class should be capable of returning a combined 70.6mpg, but on a varied test route, which took in urban and motorway routes, we couldn’t get close. We also found the ride to be a little too firm, especially around town.
Should I buy one?
There are plenty of reasons why you might find yourself looking seriously at the B-class. In facelifted form it’s a stylish mover, and the cabin upgrades give this Mercedes plenty of comfort and luxury on the road.
Still, this 2.0-litre diesel isn’t the engine to go for. It feels unrefined and doesn’t return the kind of fuel economy we’d be expecting.
With all its luxury, the B 200 CDI Sport feels a little too lavish for a small family MPV, and we suspect the sweet spot in this updated range may lie with a lesser model.
