Mercedes-Benz GLB-Class

New registrations in Europe

79,263 new Mercedes-Benz GLB-Class cars registered in the EU, Norway and Iceland between 2019 and 2022, from the European Environment Agency's CO₂ monitoring of every new car. In 2022 the largest markets were Germany (8,333), Italy (3,061), France (2,735).

Averages are weighted by registrations; CO₂ is the type-approval value (NEDC until the WLTP switch). European Environment Agency, CO₂ emissions from new passenger cars · re-use permitted with acknowledgement

Real-world fuel consumption

62,534 Mercedes-Benz GLB-Class cars registered in Europe between 2021 and 2024 report their fuel use through the on-board meter. Diesel versions average 6.6 l/100 km on the road, against 5.7 l/100 km in the official WLTP test — 15% 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.

What it costs in fuel

On real-world figures the diesel Mercedes-Benz GLB-Class uses 6.6 litres per 100 km, so 15,000 km a year takes about 980 litres: €2,226 at this week's average price in Germany, its largest market in Europe.
