The high customer satisfaction is also reflected in the sales figures: in 2014, the Mercedes-Benz B-Class won the J.D. Power satisfaction study in its vehicle segment. At 82.4 percent, the Mercedes-Benz B-Class received the highest satisfaction rating in its vehicle segment. The J.D. Power VOSS study (Vehicle Ownership Satisfaction Study) is the largest survey of German motorists and is based on the responses of more than 18,000 drivers. The study employed online interviews to poll the respondents about their level of satisfaction regarding the appeal, quality, service and operating costs of their cars no older than two years. A total of 26 manufacturers and 127 model series were rated.

The B-Class is also very popular with fleet customers. In Europe's largest comparative test based on practical experience conducted by the journal "Firmenauto" (Company Car), fleet managers repeatedly - in 2012, 2013 and 2014 - voted the B-Class the company car of the year in the "Small and Compact Vans" category.

The DEKRA used-vehicle report 2014 identified the B-Class as the vehicle with the least number of defects in the "Vans" category. Furthermore, it won the title "Vehicle of the Year".

Together with the A-, CLA- and GLA-Class, the B-Class is a member of the new-generation compact class from Mercedes-Benz. A fifth compact model has already been announced. Sales of the compact cars bearing the three-pointed star are progressing most positively: in the first half of 2014, some 215,205 customers opted for an A-, B-, CLA- or GLA-Class (+24.1% compared with the same period the year before).
