Our team of spy photographers have snagged the production version of the upcoming 2012 Mercedes-Benz B-Class dressed in a see-through plastic wrap as the car was being loaded off the transportation truck.

Clearly descended from the current-generation of Stuttgart’s mini-MPV model, the new B-Class follows a more conservative styling language than its smaller sibling, the 2012 A-Class, official patent images of which we showed you in May (see here).

The five-seat 2012 B-Class is based on a new front-wheel drive platform which brings an increase in dimensions and consequently, improved interior space for both passengers and the luggage area.

The new B-class, dubbed W246, will benefit from an updated lineup of turbocharged four-cylinder engines with direct-injection and start/stop technologies in both diesel and petrol flavors.

It is believed that Mercedes-Benz will lift the covers off the new B-Class at the 2011 Frankfurt Motor Show this September with sales to follow next year. Mercedes-Benz officials have not revealed any plans to bring the B-Class to the USA.

Stay tuned for more spy shots as well as the actual production versions of both the 2012 A- and B-Class models as we’re nearing closer to their launch.
