After three successful years, Mercedes-Benz has overhauled the design and engineering of the B-Class. The facelift programme focused on environmental compatibility, economic efficiency and comfort, with further advances being made in each of these areas. Thanks to a series of detailed improvements, the four-cylinder engines now burn up to seven percent less fuel than previously, and distinguish themselves with remarkably low exhaust emissions that undercut the current EU limits by as much as 90 percent.
Mercedes-Benz has developed a new ECO start/stop function for the high-volume B 150 and B 170 models. This switches off the engine when stopped at traffic lights, for example, producing a fuel saving of up to nine percent in practical use. Additional new developments include the bi-fuel petrol/natural-gas drive in the B 170 NGT BlueEFFICIENCY, along with active parking assist which helps drivers to both find a suitable parking spot, and then manoeuvre into it.
The B-Class continues to be available with a choice of six engines – two direct-injection diesel units (109 hp and 140 hp) delivering up to 300 Nm of torque, as well as four petrol engines with a peak power output of up to 193 hp and a maximum torque of 280 Nm. The four-cylinder power units have undergone a series of detailed improvements in order to further reduce fuel consumption.
A further new addition to the B-Class range bears the initials "NGT" on the right-hand side of its tailgate. They stand for "Natural Gas Technology" and identify a model variant which is as economical as it is environmentally compatible, courtesy of its bi-fuel drive: the B 170 NGT BlueEFFICIENCY is able to run on both natural gas and premium grade petrol while delivering an identical maximum output of 116 hp.
