The Mercedes-Benz B-Class is a compact luxury car produced by German automaker Mercedes-Benz since 2005. Mercedes-Benz markets it as a sports compact tourer. It is similar to the A-Class, though bigger and with bigger engines. The European New Car Assessment Programme (Euro NCAP) classifies it as a small MPV (multi-purpose vehicle).[1] As of December 20, 2013, delivery of B-Class vehicles reached 1 million since the launch of the B-Class in 2005.[2]

In 2005 it was introduced in spring in Europe and in autumn in Canada. The B-Class is a front-wheel drive car with a sandwich floor construction and a parabolic rear suspension.[3]

All models included many passive automobile safety systems like ESP, ABS, traction control, cornering lights, active lighting system, and headlamp assist.[4] In the event of a frontal impact the engine and transmission slides beneath the passenger compartment.

In 2008 it was updated with a start-stop system and a BlueEFFICIENCY option.[5] A new NGT variant was added, which could burn either gasoline or natural gas.[6]

In 2011 Mercedes-Benz did a world tour with three of its Mercedes-Benz F-Cell vehicles, one of which was the B-Class. The hydrogen-powered fuel cell vehicle was driven more than 30,000 kilometres in a circumnavigation of the globe, starting and ending in Stuttgart.[7]

The second generation B-Class was introduced at the 2011 International Motor Show Germany.[8] European models went on sale in November 2011. Japan models went on sale in April 2012. They assembled at Rastatt, Germany,[9] and from 2011 at Kecskemet, Hungary.[10] By summer 2013, over 230,000 second generation B-Class cars had been delivered.[11]

It included new gasoline and diesel engines, mated to either a six-speed manual or seven-speed dual-clutch transmission.[12] Drag coefficient was lowered, despite growing in overall dimensions to the benefit of interior space. A new four-cylinder engine was introduced with the model, the M270.[13]

New safety systems included adaptive cruise control, blind spot assist and, a collision prevention adaptive brake system.[14]

Variants and nomenclature[edit]

The last part of the model name indicates how the vehicle is powered:[15]

  • Natural Gas Drive: c, e.g. B 200 c (for compressed natural gas)
  • Diesel: d, e.g. B 250 d
  • Electric: e, e.g. B 250 e
  • Fuel cell f, e.g. B 200 f
  • Four-wheel drive: e.g. B 250 4MATIC


BlueEFFICIENCY is a term used by Mercedes-Benz for a series of measures which reduce fuel consumption and CO2 emissions. These include:[16]

  • Start/stop function switches off the engine temporarily when the vehicle is stationary.
  • Alternator management for regenerative braking.
  • Tyres optimised for rolling resistance have low energy requirements while driving and also help to reduce fuel consumption.

The B 180 CDI BlueEFFICIENCY Edition was available from September 2013.[17]

B 200 Natural Gas Drive[edit]

Production version includes a choice of manual and 7G-DCT dual clutch transmission, and was available from early 2013.[18] European model was set to go on sale in February 2014.[2]

B-Class Electric Drive[edit]

Initial concept versions of the B-Class Electric Drive were developed under the Mercedes-Benz BlueZERO project using batteries from Li-tec,[19] but eventually used a drivetrain from Tesla. The Electric Drive was previewed at the 2012 Paris Motor Show,[20] the 2013 New York International Auto Show,[21] and the 2013 IAA International Motor Show 2013.[11] Production for retail customers began in April 2014 at Mercedes-Benz Rastatt factory.[22] In May 2014, Mercedes announced the B-Class Electric Drive will be available in Germany and the UK in the first quarter of 2015.[23] In November, Mercedes-Benz announced pricing for Germany and started accepting orders.

The concept has an electric motor rated 136 PS (100 kW; 134 hp) and 310 N·m (229 lb·ft), 36 kWh lithium-ion battery from Tesla Motors. The vehicle has a driving range of 200 km (124 mi) with a top speed of 150 km/h (93 mph).[20] The battery can be charged at any standard domestic 230 V power outlet or 400 V rapid charging terminal.

Pricing in the U.S. starts at US$41,450 before any applicable tax credits and other government incentives.[24] In 2015 over 1900 electric B-class were sold in the USA.[25] The United States Environmental Protection Agency (EPA), under its five-cycle testing, rated the 2014 B-Class Electric Drive with an all-electric range of 87 mi (140 km). The energy consumption was rated at 40 kWh/100 miles for combined city/highway driving, corresponding to a fuel economy of 84 miles per gallon gasoline equivalent - MPGe - (2.8 L/100 km; 101 mpg imp). The rating for city driving is

85 mpg-e (2.8 L/100 km; 102 mpg imp), and 83 mpg-e (2.8 L/100 km; 100 mpg imp) for highway.[26]
