Mercedes-Benz CLA-Class: real-world fuel consumption
Fuel meter readings from 100,338 Mercedes-Benz CLA-Class cars reported in 2024, split by engine.
Excluding plug-in hybrids, the average is 6.8 L/100 km on the road against 5.9 officially (15% above official).
Lowest real-world consumption: Diesel · 85 kW (116 hp) at 5.6 L/100 km.

Engines with fewer than 100 cars in the data are not shown. Hybrid includes mild hybrids (48 V) as registered by the manufacturer.
Plug-in hybrid
| Engine | cars | Official (WLTP) | Real world | Electric share | Gap |
|---|---|---|---|---|---|
| Plug-in hybrid · 118 kW (160 hp) | 21,075 | 1.1 | 5.1 | 26% | +359% |
| Plug-in hybrid · 120 kW (163 hp) | 6,559 | 0.9 | 5.3 | 27% | +465% |
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.
By reporting year
| cars | Real world | |
|---|---|---|
| 2021 | 8,395 | 6.8 |
| 2022 | 28,334 | 6.8 |
| 2023 | 44,209 | 6.8 |
| 2024 | 72,702 | 6.8 |
The same cars are reported again each year with their lifetime totals, so years are not added together.
