The A-Class has been the leading light in the Mercedes-Benz compact car line-up, but the B-Class hasn’t been forgotten – pictured here is the test mule for the next-generation successor to the model which was facelifted in 2014.
No confirmation of what the upcoming B-Class will be based upon, though given its present architecture, the new model could be built upon the new Modular Front Architecture (MFA2) platform that will also underpin the likes of the upcoming A-Class and A-Class sedan.
Little in the way of interior detail is available, though extrapolating from the exterior’s design language, the new B-Class should also adopt the interior cues as applied to the upcoming A-Class, which will include design touches such as the floating tablet for the infotainment screen, updated steering wheel and possibly widescreen digital instrumentation as an option.
As part of the compact range, the MFA2’s transverse layout should see the enlisting of petrol and diesel four-cylinder engines, in various states of tune. The new platform’s flexibility should allow for the possibility of a plug-in hybrid variant further down the line, as well.
