The second generation Mercedes B-Class was unveiled at the Frankfurt Motor Show in September 2011 and went on sale soon after.
Looks like Mercedes is already updating the B-Class as you can see from our latest spy shots.
The prototype has a disguised front, hiding a new bumper, revised grille, new headlights in one design/part as is on all new MB models. The rear revels new exhausts, which are similar to the ones we have seen on the upcoming new C-Class.
We also expect minor changes to the engine line-up with improved fuel economy and CO2 emissions.
We expect the updated model to go on sale in late 2014.
