Audi Q8

The Audi Q8 (2018 on) is the coupe-roofed flagship of Audi's SUV range - effectively a sleeker, more style-led Q7 sharing the same platform, but with five seats and a lower, racier roofline. UK cars span petrol, diesel, mild-hybrid and plug-in hybrid, topped by the thunderous SQ8 and RS Q8. It's about presence and a plush, tech-rich cabin rather than the Q7's practicality. As a used buy it's an imposing, well-built luxury SUV bought on style as much as substance.

Forecourt score

Value 70 · Reliability 94 · Insurance 22

The Audi Q8 holds its value well and is dearer to run than most. Its MOT-based reliability is excellent, 88 out of 100, ahead of 94% of the cars we track. On three-year value retention it ranks better than 70% 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.

Based on the 2023 car with 29,214 miles you entered above — worth about £40,000 today — here is the cost of owning it for the next 5 years, at roughly 9,738 miles a year.

Best age to buy — around 4 years

A 4-year-old example loses roughly £6,300 a year — under half the £13,150 a one-year-old sheds. The steepest drop is behind it.

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.

Safety rating

Euro NCAP's independent crash-test rating for the Audi Q8, from its 2019 assessment.

5/5
TEST YEAR2019
Rating expired (test protocol superseded)

The Audi Q8 shares almost all of its structure with the Q7 and has the same safety equipment fitted as standard.

Independent crash-test data from Euro NCAP. Star ratings reflect the test protocol of the year shown — newer protocols are stricter, so a 5-star from 2024 represents a higher bar than a 5-star from 2014.

MOT outlook

How this model fares at its MOT as it ages — from 27,139 real DVSA test records.

Things owners say

  • 01The diesels suit high miles; the PHEV lowers BIK if charged; the SQ8/RS Q8 are the performance flagships.
  • 02Shares its platform with the Q7, Bentley Bentayga and Porsche Cayenne - serious engineering underneath.
  • 03The coupe roof and five-seat-only layout trade the Q7's space for style; air suspension is a cost item to check.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Audi Q8, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens 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

Desirable SUVs like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.

Parts theft

Higher

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

  • Keep keys in a Faraday pouch and away from the front door to block relay attacks.
  • A catalytic-converter guard or forensic marking makes a hybrid far less appealing to cut.
  • A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.

Clean-air zones

Whether driving a Audi Q8 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.

Company car tax

What HMRC's Benefit-in-Kind charge looks like if you ran this Audi Q8 as a company car, by tax year and income-tax band. Calculated from a CO₂ of 268 g/km and a WLTP electric range of 48 miles, using £84,000 as the P11D value.

Our reliability score for the Audi Q8 is 88 out of 100 (excellent), derived from DVSA MOT records, with a first-time MOT pass rate of about 91% at the reference age.
What economy does the Audi Q8 get?
Expect roughly around 2.6 miles per kWh for a typical Audi Q8, based on official figures and our running-cost model. Real-world figures vary with driving style, load and conditions.
What are the common problems on the Audi Q8?
On the Audi Q8, the issues that come up most by mileage include Tyres & wheels, Driver's view and Brakes. The section above breaks down each one with its typical mileage, repair cost and severity.
How many Audi Q8s are on UK roads?
About 16,100 Audi Q8s are currently taxed and on the road in the UK, from DfT vehicle-licensing data.

Common questions

Audi Q8, answered from the data

Is the Audi Q8 reliable?
The Audi Q8 scores 88/100 on Forecourt's MOT-based reliability measure, ahead of 92% of the cars we track. That is computed from 27,139 real DVSA MOT test results.
How much does a used Audi Q8 cost?
A 2023 Audi Q8 with around 29,214 miles is worth roughly £40,000 today (typical range £34,950–£45,100). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
How quickly does the Audi Q8 depreciate?
A new Audi Q8 typically loses about 36% 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 Q8?
The Audi Q8 sits in insurance group 30 of 50 — the middle 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 Q8?
The most common age-related issues we track for the Audi Q8 are: tyres & wheels (typically around over 100k miles, £80-£500 to put right); driver's view (typically around over 100k miles, £60-£300 to put right); brakes (typically around 60k-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 Q8 cost to run?
Expect around 32 mpg combined, £195 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.
