Real-world fuel consumption

43,948 Audi A4 Avant cars registered in Europe between 2021 and 2024 report their fuel use through the on-board meter. Diesel hybrid versions average 6.2 l/100 km on the road, against 5.3 l/100 km in the official WLTP test — 17% more.

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.
