Ranked #250 car in the UK · Saloon · 145 units sold last year
The Audi A8 (D5, 2018 on) is Audi's understated luxury flagship - a hushed, tech-laden limousine that's more discreet than a Mercedes S-Class or BMW 7 Series. UK cars are mild-hybrid petrols and a long-range 60 TFSI e plug-in hybrid, all with quattro. Supremely quiet and beautifully built, with a long-wheelbase option for rear-seat space, it's a lot of luxury saloon for the money used - if a complex one to maintain.
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 3 · Reliability 85 · catalogue percentiles
The Audi A8 loses value faster than most cars and is dearer to run than most. Its MOT-based reliability is excellent — an MOT score of 87/100, ahead of 63% of the cars we track. On three-year value retention it ranks better than 3% 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.
Flip side for used buyers: heavy depreciation is the first owner’s loss and the used buyer’s discount — a reliable car with a low score here can be a strong used purchase at today’s prices.
Estimates are tuned to the version you choose.

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).

How this model fares at its MOT as it ages — from 269,366 real DVSA test records.
MOT pass rate by age
A 3-year-old A8 passes its MOT 89.7% of the time; by 25 years that has slipped to 71.2%. The y-axis is zoomed to this model’s range so the trend is readable.
Longevity
From 1,144 vehicles registered in 2018.
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.
What’s on the road
The fuel-type split of every A8 with MOT history in the DVSA record. From 26,509 vehicles tested at least once - not the number on the road today, which is lower.
What fails at the first MOT
The defect categories a A8 registered 2020–2023 fails on at its first MOT, from 1,160 first tests. Every car here is the same age and the same generation, so these are the faults that show up first - not the wear a high-mileage older example collects.
Share of first MOT tests recording at least one defect in that category. DVSA test-item categories, not parts: “Driver’s view” covers mirrors, wipers and glass.
Typical mileage by age
The average odometer reading for a A8 at MOT, by age — measured from the same DVSA records, not assumed. A useful yardstick for whether a given car has done more or fewer miles than its age suggests.
Mean recorded mileage at MOT by vehicle age, from DVSA test records. Ages below three are not shown: the first MOT is due at three years, so the few cars tested earlier are a self-selected minority rather than a representative sample. Ages with at least 10 tests shown.

Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Audi A8, or your exact vehicle, has any outstanding recalls on the official DVSA service.

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 A8 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. |

P11D value is approximated from the latest new price; the exact figure on your tax code will depend on options fitted. The 4% diesel surcharge applies only to non-RDE2 (pre-2021) diesels — we assume RDE2 compliance for current models. Bands and rates from HMRC's Autumn Budget 2024 confirmation through 2029/30.
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
~115
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.
These are segment estimates, not manufacturer figures. 296 of 325 catalogued cars share one of 14 identical dimension sets, so they describe a class rather than this particular car. Sourced figures replace them model by model.
