Mercedes-Benz B-Class Plug-in hybrid · 120 kW (163 hp)

Official (WLTP)L/100 km
Real worldL/100 km
+403%

Measured by the on-board fuel meters of 2,502 cars · 2024 data

Real-world consumption is 403% above official. 132 of the other 187 plug-in hybrids in the data come closer to their official figure.

How much is driven on electricity

Owners drive 34% of their kilometres in electric mode with the engine off.

A further 5% is driven with a charged battery but the engine running.

They charge on average 7.8 kWh from the grid per 100 km driven.

Official electric range: 74 km.

The official WLTP figure for plug-in hybrids assumes a share of electric driving based on range. When cars are charged less often than assumed, real consumption is far higher.

How much drivers actually use

Half of the cars use between 2.8 and 6.1 L/100 km. The most economical tenth stays under 1.8; the thirstiest tenth uses more than 7.2.

Each bar is a 0.5 L range; its height and the figure above it show what share of cars fall in that range.

L/100 km · Each car’s lifetime average from its fuel meter. Cars with less than 1,000 km are left out.

Is my consumption normal?

L/100 km

Trip computers are often a few percent optimistic. Short trips, winter, motorways and towing raise consumption.
