MOT test results in Great Britain

Real-world fuel consumption

100,334 Mercedes-Benz cla cars registered in Europe between 2021 and 2024 report their fuel use through the on-board meter. Petrol versions average 8.0 l/100 km on the road, against 6.8 l/100 km in the official WLTP test — 18% more. Plug-in hybrids use 5.1 l/100 km against 1.1 l/100 km on paper, with 26% of their distance covered with the engine off.

Litres per 100 km: total fuel used divided by total distance driven, from the car's own fuel consumption meter (OBFCM), collected in 2024 by the manufacturers, mostly remotely, and by national authorities. WLTP figures are the type-approval CO₂ values converted to litres. Hybrids, including mild hybrids, do not plug in; plug-in hybrid figures include the distance driven on electricity.
