Mercedes-Benz B55 V8 Concept: official details, photos and specs

Article by Christian Andrei, on January 3, 2011

Although we don’t know the reason yet, it appears that Mercedes-Benz decided to let Andreas Würz, a foreman in the technical vocational training department, to create a very special edition of the B-Class: a B 55 with a V8 engine and rear-wheel drive.

Together with his fellow-foreman Matthias Rieger from the electrics/electronics installation section, Andreas Würz created a new concept that offers the same interior space as a standard B-Class.

As expected, both the exterior and the interior were improved in order to support the big amount of power found under the hood. Based on the B200 CDI, the new car received an impressive 5.5-litre V8 engine developing 388 hp and 530 newton metres of torque and mated to a seven-speed automatic transmission.

In order to support this amount of power, the engineers installed a rear axle of an older W 210 series E-Class, while the brakes were borrowed from a C32 AMG, which means that the car received a perforated and internally ventilated disc brakes in size 345 x 34 mm at the front and perforated and internally ventilated disc brakes in size 300 x 30 mm at the rear. The design of the car is completed by the new 18-inch AMG wheels wrapped in high performance tires.

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. Inside, the car features Alcantara linings for the A, B and C-pillars as well as a roof liner.

The seats are also finished in a leather/Alcantara combination provided by the specialists at Johnson Controls (the company which will acquire Recaro sport seats specialist). The most impressive result is the total weight of the car, 1620 kg, which means that the car is with 180 kg heavier than the standard version.

Plant manager Wesp is equally proud of the result: "The team of trainees has done a superb job, and placed a spotlight on the sporty genes of the B-Class that nobody could have imagined." Training manageress Manuela Rascher is likewise very pleased: "The B 55 shows what our training workshop can do."
