With its main dimensions of 4.36 meters (171.65 inches) in length, 1.786m width (70.31 in.), or 2.01m (79.13 in.) with the mirrors, 1.56m (61.4 in.) height and 2.7m (106.3 in.) for the wheelbase, the luggage compartment of the 2nd generation B-Class has a capacity of 488 litres (17.23 cu. ft.) on the basic model, which comes with a standard folding rear seat backrest (60:40 split).
Rear cargo volume can be increased to 666 litres (23.5 cu. ft.) with the optional Easy-Vario-Plus system, which includes separate fore/aft adjustment of the rear seats by up to 140 millimeters (5.5 in.).
The first visible change in the petrol or diesel versions can be seen in the new bumper, wide radiator trim with two louvres and now integral daytime running lamps in the headlamps.
Optional high performance LED headlamps (not available for the B-Class Electric Drive or Natural Gas Drive) can increase safety at night with their wide beam pattern and light of a color similar to daylight.
The new rear bumper gets a contoured covering and an additional chrome trim strip, with the bicolor tail lamps featuring LED technology, making the vehicle more visible.
Enhancements of the updated interior include a larger free-standing head unit display, with a diagonal of up to 20.3 cm (8 inches), and the dial layout for the instrument cluster. There are 12 colors for the ambient lighting to chose from.
Mercedes-Benz has also aligned the model range to its other compact models, with three new design and equipment lines: Style, Urban and AMG Line.
Each version gets a number of distinctive exterior and interior details. The Night, Exclusive and AMG Exclusive packages add more options for individualization.
Options include the Keyless-Go access and drive authorization system with a starting function, allowing the vehicle to be opened, started and locked simply by carrying the electronic key with the user.
Autonomous partial braking
In addition to the existing standard and optional B-Class safety and driving assistance systems, new functions come with the Collision prevention Assist Plus, which extends the functionality of the Collision prevention Assist with autonomous partial braking to reduce the risk of rear-end collisions.
The standard Attention Assist feature has also been upgraded to operate within an extended speed range (60 - 200 km/h, 37 - 124 mph), now using a five-stage bar display to visualize the driver's current attention level.
With the new B-Class, the Mercedes connect me service offers a more intuitive operation, with more accessible functions thanks to animated menus and visual representations on a larger display in the head unit.
Basic Mercedes connect me services, which can be used with the standard communications module, include accident recovery (depending on markets), service maintenance and incident management.
In an accident, the emergency call system automatically connects the occupants with the MB Emergency Call Centre and sends the position and condition of the vehicle to the rescue operations centre. A rescue vehicle can then be dispatched immediately. While the system works automatically, it can also be triggered manually.
The special Remote Online equipment enables customers to connect with their vehicle anywhere and at any time via the URL "connect.mercedes.me", or for example, to query by smartphone the fuel level in their fuel tank.
In the B-Class Electric Drive, the Mercedes connect me services are more extensive, also via "connect.mercedes.me", as the current charging level of the lithium-ion battery and current vehicle range can be queried from a distance.
The range of Mercedes connect me services also allow (depending on the temperature) to preheat or precool the vehicle ready for a specified departure time.
