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) | 25,585 | 1.1 | 4.8 | 31% | +351% |
| Plug-in hybrid · 120 kW (163 hp) | 12,474 | 0.9 | 5.1 | 29% | +479% |
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 | 15,343 | 6.5 |
| 2022 | 55,397 | 6.5 |
| 2023 | 77,850 | 6.5 |
| 2024 | 121,587 | 6.5 |
The same cars are reported again each year with their lifetime totals, so years are not added together.
