Audi RS4
The B9 Audi RS4 Avant (2018 on) is the understated 450bhp super-estate - a twin-turbo 2.9 V6 with quattro and a vast boot, capable of family-hauling and back-road heroics in the same trip. It looks almost like a regular A4 Avant, which is exactly its appeal: huge real-world pace and practicality with none of the shoutiness. The default choice for buyers who want one fast car that does everything.
How these figures are sourced — the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

The short version
Forecourt score
Value 46 · Insurance 7 · catalogue percentiles
The Audi RS4 holds its value about averagely and is dearer to run than most. On three-year value retention it ranks better than 46% of models.
The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20) — the from-new ownership picture. Higher is better; running cost is not yet folded in.

Best age to buy — around 6 years
A 6-year-old example loses roughly £5,650 a year — 50% less than the £11,400 a one-year-old sheds. The steepest drop is behind it.
Uses current UK pump and home-charging prices (DESNZ weekly), typical-driver insurance and manufacturer service intervals. "Fuel per mile" is just the energy input — so an EV at ~9p and a diesel at ~22p make running-cost comparison direct. A guide; your own costs will vary.

Reliability
Not enough first-MOT data yet. This measure needs cars registered from 2020 that have reached their first MOT at three years old; too few have so far for a figure worth publishing.
Not enough first-MOT data yet — no score. A car needs 100 first MOTs from 2018 registrations onward before this can be measured.

Things owners say
- 01The 2.9 V6 biturbo is effortlessly quick; quattro means the pace is usable all year.
- 02A genuine do-it-all car - estate practicality with supercar-baiting straight-line speed.
- 03Big brakes, big tyres, big bills - factor in consumables, and check for kerbed wheels and uneven tyre wear.
Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Audi RS4, or your exact vehicle, has any outstanding recalls on the official DVSA service.
Check on GOV.UKOpens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.
Theft risk
A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.
Whole-car theft
Higher
Higher-value cars like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.
Parts theft
Around average
Parts-theft risk is around average — catalytic-converter theft is the main thing to be aware of on any petrol or diesel car.
Worth doing
- Keep keys in a Faraday pouch and away from the front door to block relay attacks.
- A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.
Clean-air zones
Whether driving a Audi RS4 into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.

| London | All of Greater London (within the M25) | £12.50 | Likely exempt Petrol from 2006 meets Euro 4. |

Servicing & the dealer network
How well-supported Audi is across the UK — a practical read on how easy servicing, parts and warranty work will be to find.
Franchised UK dealers

Large network
Premium mainstream
Network size relative to the UK's largest (Audi is 2.6% of all franchised outlets)
Servicing, parts and warranty work are easy to find UK-wide, and most independent garages know the brand well — which keeps maintenance competitive.
For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.
Approximate figures, curated from public UK industry sources (NFDA, Car Dealer Magazine). Franchised networks shrink year on year — these indicate network size, not an exact count.

Common questions
Audi RS4, answered from the data
- How much does a used Audi RS4 cost?
- A 2023 Audi RS4 with around 22,839 miles is worth roughly £50,400 today (typical range £41,950–£58,800). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
- How quickly does the Audi RS4 depreciate?
- A new Audi RS4 typically loses about 40% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.
- What insurance group is the Audi RS4?
- The Audi RS4 sits in insurance group 44 of 50 — the more expensive end of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.
- What goes wrong on a used Audi RS4?
- The parts most often recorded at MOT on the Audi RS4 are: suspension (typically around over 100k miles, £150-£450 to put right); tyres & wheels (typically around over 100k miles, £80-£500 to put right); brakes (typically around over 100k miles, £150-£500 to put right). A full service history and a recent MOT with no advisories are the best protection.
- What does the Audi RS4 cost to run?
- Expect around 30 mpg combined on the RS4 Avant 2.9 TFSI biturbo 450 quattro, £200 a year in road tax, about £290 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.
- Is the Audi RS4 ULEZ compliant?
- Whether a Audi RS4 is ULEZ compliant depends on its engine and registration date: petrol from 2006 and diesel from September 2015 generally qualify, and electric versions are always exempt.
- How many Audi RS4s are on UK roads?
- About 5,914 Audi RS4s are currently taxed and on the road in the UK, from DfT vehicle-licensing data.
