The first generation B-Class was introduced in Europe, Australia, and other parts of the world in spring 2005, and in Canada in autumn 2005. The B-Class uses front-wheel drive with sandwich floor construction, parabolic rear suspension,[4] and a two-box design — one for the drivetrain and another for the shared passenger and luggage compartment. The B-Class maximises its interior volume via its height. Having derived from the smaller A-Class, it retained that car's sandwich floor concept.[5]

All models included passive automobile safety systems including ESP, ABS, traction control, cornering lights, active lighting system, and headlamp assist.[6] In the event of a frontal impact the engine and transmission slide beneath the passenger compartment.

In 2008 it was updated with a start-stop system and a BlueEFFICIENCY option.[7] A new NGT variant was added, which could burn either gasoline or natural gas.[8]

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.[9]

B-Class Electric Drive

Production Mercedes-Benz B-Class Electric Drive

The Mercedes-Benz Concept B-Class Electric Drive was unveiled at the 2012 Paris Motor Show.

Production Mercedes-Benz B-Class Electric Drive charging

Initial concept versions of the B-Class Electric Drive were developed under the Mercedes-Benz BlueZERO project using batteries from Li-tec and a drivetrain from Tesla, but Mercedes switched to using a drivetrain developed by Mercedes itself soon after.[24][25] The Electric Drive was previewed at the 2012 Paris Motor Show,[26] the 2013 New York International Auto Show,[27] and the 2013 IAA International Motor Show 2013.[15] Production for retail customers began in April 2014 at Mercedes-Benz Rastatt factory.[28] In May 2014, Mercedes announced the B-Class Electric Drive will be available in Germany and the UK in the first quarter of 2015.[29] 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).[26] The battery can be charged at any standard domestic 230 V power outlet or 400 V rapid charging terminal.

The B-Class Electric Drive was introduced to the U.S. in December 2013 as an early 2014 model. It is one of the only B-Class models to ever be sold in the U.S. market, as well as being the first Mercedes-Benz vehicle to ever be offered in an electric variant, though it was only available in certain states that required ZEV mandates. It was originally rebadged as the B-Class Electric Drive, but in 2017, it was renamed the B250e. Pricing in the U.S. starts at US$41,450 before any applicable tax credits and other government incentives.[30] In 2015, over 1,900 electric B-class vehicles were sold in the US, but in 2017, only 4,100 electric B-class vehicles were sold and were shortly discontinued due to low demand.[31]

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.[32]

The third generation B-Class was launched at the Paris Motor Show on 2 October 2018. At launch, the vehicle was claimed to feature the Intelligent Drive semi-automated driving system borrowed from the S-Class.[35]

The vehicle received a facelift in 2023.[36]

The design was improved with a much shorter front overhang. The controversial sculpting on the side part of the vehicle was not carried over to the W247 B-Class. Three infotainment system options is available, with entry-level models getting dual seven-inch displays. A seven-inch display with the larger 10.25-inch display is available, with top-tier models getting a pair of the large displays. It is powered by a full MBUX infotainment system, giving B-Class buyers access to its functions through a standard touchscreen. Features such as intelligent voice control, augmented reality, and a head-up display are optional.[35] The all-electric configuration was removed, but a plug-in hybrid option was introduced. The plug-in hybrid comes with a 10.9 kWh battery which optionally supports DC charging and provides a WLTP combined cycle range of 66 km.[37]
