MOT test results in Great Britain
1,191 RS4 cars took their annual MOT test in 2023; 82% passed first time, against 61% for all cars of the same ages. Older cars fail more often, so compare a year with the same year of other cars.
| First registered | Tests | Passed first time |
|---|---|---|
| 2014 | 198 | 84% |
| 2013 | 178 | 87% |
| 2007 | 433 | 78% |
| 2006 | 382 | 82% |

Real-world fuel consumption
1,080 Audi RS4 cars registered in Europe between 2021 and 2024 report their fuel use through the on-board meter. Petrol versions average 11.9 l/100 km on the road, against 9.9 l/100 km in the official WLTP test — 20% more.
| Fuel | Cars | On the road | WLTP | Difference |
|---|---|---|---|---|
| Petrol | 1,080 | 11.9 | 9.9 | +20% |
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.
