The new Mercedes-Benz B-Class features new petrol and diesel engines as well as new manual and automatic transmissions. The new four-cylinder petrol engines (internal designation M270) mark the launch of a completely new engine series. The combustion process is based on the third-generation Mercedes-Benz direct injection system which was introduced last year with the BlueDIRECT V6 and V8 engines. Its use in the B-Class marks this technology’s debut in the compact segment.
The new 6-speed manual transmission designed along similarly compact lines as a three-shaft transmission is a close relative of the DCT. Extremely easy gear shifting, low shift forces, low internal friction and a low weight are among its most important characteristics.
The characteristic lines of the exterior design indicate both of these attributes: front and rear sport a width-emphasizing design, with a wide, prominent grille and headlamps extending along the sides at the front while the rear end features a wide rear window, two-piece tail lights with horizontally offset meander and a large tailgate with low loading sill.
This transmission is extremely compact, extremely variable with regard to adaptation of the engine speed thanks to seven gears, features an electric oil pump for start/stop capability, shifts gear without any interruptions in tractive power and combines the comfort of an automatic with the efficiency of a manual transmission
The Mercedes-Benz B-Class is optionally available with the so-called EASY-VARIO-PLUS system. This enables simple reorganisation of the interior so as to enable the transportation of bulky items.
The world premiere of the All-New Mercedes-Benz B-Class (length/width/height: 4359/1786/1557 millimetres) will take place at the 2011 Frankfurt International Motor Show. It will be making its way to European dealers in November 2011.
