External changes have been limited primarily to the B-Class' bumpers. At the front there are reshaped air intakes and the driving lights have moved to within the reworked headlight clusters.
Out the back, the tail-lights have been subtly redesigned to include more LEDs. The rear bumper has also been revised to incorporate stylised exhaust tip housings, as well as a new chrome strip for some trim lines.
Under the hood, the turbocharged engine range carries on essentially unchanged. The petrol engine lineup begins with the 90kW/200Nm 1.6-litre B180 and ends with the 155kW/350Nm 2.0-litre B250. As far as diesels go, the range begins with the 66kW/240Nm 1.5-litre B160 and is topped off by the 130kW/350Nm 2.1-litre B220.
Also offered overseas are the 115kW/270Nm natural gas version of the B200 and the 132/340Nm B-Class Electric Drive.
Currently only the 100kW/300Nm B200 CDI, 90kW/200Nm B180, 115kW/250Nm B200 and 155kW/350Nm B250 are available down under. All Australia-bound models are fitted exclusively with the company's seven-speed dual-clutch transmission.
Inside the cabin, the B-Class can now be had with a larger 8.0-inch free-standing central screen. Autonomous emergency braking is available for the first time on the B-Class, while the car's attention alert system now operates when travelling between 60 and 200km/h, instead of 80 to 180km/h.
Options include push button start, smart entry key and high performance LED headlights.
The refreshed B-Class will go on sale from November across Europe and it's likely to land on our shores sometime in 2015.
