Every engine: official vs real
| Engine | cars | Official (WLTP) | Real world | Gap |
|---|---|---|---|---|
| Petrol · 450 kW (612 hp) | 461 | 14.1 | 15.8 | +12% |
| Diesel · 243 kW (330 hp) | 6,156 | 7.2 | 9.0 | +25% |
| Diesel · 210 kW (286 hp) | 3,292 | 7.0 | 8.4 | +20% |
| Hybrid · 370 kW (503 hp) | 3,520 | 10.7 | 12.9 | +21% |
| Hybrid · 320 kW (435 hp) | 1,706 | 8.8 | 11.1 | +26% |

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 · 270 kW (367 hp) | 3,657 | 0.8 | 7.1 | 29% | +852% |
| Plug-in hybrid · 450 kW (612 hp) | 1,010 | 4.5 | 14.1 | 12% | +215% |
| Plug-in hybrid · 220 kW (299 hp) | 214 | 0.7 | 6.2 | 31% | +818% |
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 | 3,703 | 9.5 |
| 2022 | 8,685 | 9.6 |
| 2023 | 13,017 | 9.7 |
