Mercedes-Benz B 250 e: The all-rounder

Sep 14, 2019

The B-Class is the perfect (family) car for all those who attach importance to space, comfort and safety, and despite its sporty appearance it offers better interior dimensions than the preceding model. At the same time, the B-Class is an agile drive and even more comfortable than its predecessor. As the B 250 e (weighted fuel consumption 1.6-1.4 l/100 km, weighted CO2 emissions 36-32 g/km, weighted power consumption 15.4-14.7 kWh/100 km)[1] the all-rounder is even more economical yet more dynamic than ever before.

In terms of the avant-garde interior, the B-Class again breaks new ground with the mono-volume design of the instrument panel and is every bit as revolutionary as the A-Class. With a Cd value starting at 0.24, the new B-Class betters its predecessor and is the leader in its segment. It too has driving assistance systems with cooperative driver support, and thus provides one of the highest levels of active safety in this segment with functions adopted from the S‑Class. The new ENERGIZING seat kinetics supports orthopaedic changes in the seating posture by means of minute changes to the inclination of the seat cushions and backrest.

For the compact models, the third-generation plug-in technology was adapted and scaled for the transverse engine. Electrically powered driving pleasure and everyday suitability are the main focus. The highlights of the B 250 e with EQ Power confirm this:

  • Electric range 70-77 km (NEDC)
  • Electric output 75 kW
  • System output 160 kW
  • System torque 450 Nm
  • Top speed 140 km/h (electric)/235 km/h (overall)
  • Acceleration from 0-100 km/h in 6.8 seconds
  • Hardly any restrictions in the load compartment

The B 250 e can be charged with alternating or direct current. A corresponding vehicle socket is located in the right-hand side wall of the vehicle. This means that the compact plug-in hybrid can be charged from 10-100 percent SoC (state of charge) at a 7.4 kW wallbox with alternating current (AC) within 1 h 45 mins., and with For direct-current charging (DC) the battery can be charged from 10-80 percent SoC in around 25 minutes.

[1] The stated figures are the measured "NEDC CO2 figures" in accordance with Article 2 No. 1 Implementing Regulation (EU) 2017/1153. The fuel consumption figures were calculated based on these figures. The range and the electrical consumption have been determined on the basis of Regulation (EC) No. 692/2008. A different value is applied in accordance with EmoG. A higher value may apply as the basis for calculating the motor vehicle tax.
