Mercedes-Benz C-Class Plug-in hybrid · 155 kW (211 hp)
Measured by the on-board fuel meters of 1,298 cars · 2024 data
Real-world consumption is 295% above official. 74 of the other 187 plug-in hybrids in the data come closer to their official figure.
How much is driven on electricity
Owners drive 22% of their kilometres in electric mode with the engine off.
A further 12% is driven with a charged battery but the engine running.
They charge on average 5.0 kWh from the grid per 100 km driven.
Official electric range: 55 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 5.1 and 7.7 L/100 km. The most economical tenth stays under 3.8; the thirstiest tenth uses more than 8.6.
Each bar is a 0.5 L range; its height and the figure above it show what share of cars fall in that range.
