Ranked #124 car in the UK · Estate · 304 units sold last year
The C8 Audi RS6 Avant (2020 on) is the legendary 600bhp twin-turbo V8 super-estate - mild-hybrid assisted, four-wheel drive, and absurdly fast for something that swallows a family and the dog. It's the ultimate Q-car: supercar pace, estate practicality, and a thunderous V8 soundtrack. Heavy and thirsty, yes, but few cars cover ground this quickly while looking this usefully ordinary.

The short version
Forecourt score
Value 41 · Reliability 54 · Insurance 22
The Audi RS6 Avant holds its value about averagely and costs about average to run. Its MOT-based reliability is good, 74 out of 100, ahead of 54% of the cars we track. On three-year value retention it ranks better than 41% of models.
The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20). Higher is better; running cost is not yet folded in.

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.

How we estimate this
Indicative annual comprehensive premium estimates. The 'Typical' figure represents an average UK driver in each age band; Lower and Higher risk show the realistic spread driven by factors UK insurers legitimately price on (postcode, occupation, claims history, NCB, voluntary excess, modifications). Based on 10,000 miles/yr, £250 voluntary excess, and the no-claims bonus selected above. Always get individual quotes before buying.
Adjust the annual mileage to match how you'll actually use the car. Insurance is what you selected above (age 33-39, typical risk, 3 yrs NCB).

MOT pass rate by age
A 3-year-old RS6 Avant passes its MOT 87.5% of the time; by 23 years that has slipped to 80.5%. The y-axis is zoomed to this model’s range so the trend is readable.
Longevity
From 287 vehicles registered in 2003.
Survival by registration year
Each point is one registration cohort. Older cars on the left, newer on the right. A flatter line means the model holds up over time; a steep drop means cohorts disappear from UK roads faster.

Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Audi RS6 Avant, 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.
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

Hybrid versions are a catalytic-converter target — a hybrid cat is rich in precious metals and can be cut out in about a minute.
Worth doing
Whether driving a Audi RS6 Avant 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.
| City | Area | Daily charge | Likely outcome |
|---|---|---|---|
| London | All of Greater London (within the M25) | £12.50 | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Birmingham | Inside the A4540 Middleway | £8.00 | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Glasgow | City centre | — | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Edinburgh | City centre | — | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Aberdeen | City centre | — | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Dundee | City centre | — | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |

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.
