 Mercedes B55 Concept, 2011

Spacious, innovative and safe, the compact models of the Mercedes A and B-Class score with their high practicality, and have found favour with more than 2.5 million customers as a result. An extraordinary one-off example has now been built at the Rastatt plant, and shows the B-Class in a completely new light: a B55 with a V8 engine and rear-wheel drive.

•     The spatial concept of the B-Class was to remain unchanged.
•     On the outside too, there were only to be minor indications of the conversion work.
•     The interior was to be upgraded in line with the new vehicle class being aspired to.
•     And the result of the conversion was to be in large measure suitable for day-to-day driving.

The exhaust system was a clever combination of various replacement part items, and took the form of a twin-pipe system emerging at the centre of the rear end. This is where the one-off, christened the B55 gets its typical, burbling sound - once the ignition key has been turned, all heads in the vicinity are guaranteed to swivel simultaneously in the direction of the B-Class.

Intensive perusal of parts catalogues also solved the second major transplantation problem, namely the drive axle at the rear. It emerged that the rear axle of an older W 210 series E-Class would be a very good geometrical fit.
For the brakes the team also struck gold in the replacement parts catalogue, this time in the C32 AMG listing. Perforated and internally ventilated disc brakes in size 345 x 34 mm were implanted at the front, with perforated and internally ventilated disc brakes in size 300 x 30 mm at the rear. The system was combined with striking 8.5 x 18 AMG sports wheels in a five-spoke design shod with 235/40 ZR 18 Y tyres at the front and 9 x 18 wheels with 255/35 ZR 18 Y tyres at the rear. The maximum steering angle at the front axle was limited to suit. The team had recourse to a typical item from the tuner's toolbox for the suspension, installing a coil-over suspension by K&W.

The seats in a leather/Alcantara combination were provided by the specialists at Johnson Controls, who are located on-site in Rastatt. The finishing touches were added to the B55 in the paint shop of the Rastatt plant. In trendy white with dark-painted radiator louvres and smoked headlamp lenses, the B-Class cuts an imposing figure but only gives a discreet indication of the powerpack concealed beneath its bonnet.
