The Mercedes-Benz B-Class is a subcompact executive car manufactured and marketed by Mercedes-Benz since 2005. Based on the A-Class with larger dimensions, the European New Car Assessment Programme (Euro NCAP) classifies it as a small MPV.
Mercedes-Benz had presented a concept car Vision B Compact Sports Tourer at the 2004 Paris Motor Show. The concept previewed some features that would be available on the production B-Class. The Vision B was based on the layered platform, so that the drivetrain would be placed partly in front of and underneath the passengers.
As of 20 December 2013, delivery of B-Class vehicles reached 1 million sales worldwide since its launch in 2005.
