Audi S5

The Audi S5 is the warm, all-weather performance version of the A5 - a turbocharged six-cylinder coupe or Sportback with quattro, offered as a petrol and, in some forms, a diesel. It's the sensible-shoes fast Audi: rapid and surefooted in any conditions, comfortable enough daily, and subtler than the full-bore RS5. As a used buy it's a discreet, quick and well-built quattro GT for buyers who want genuine pace without shouting about it.

Forecourt score

Value 95 · Reliability 66 · Insurance 1

The Audi S5 holds its value well and is dearer to run than most. Its MOT-based reliability is good, 78 out of 100, ahead of 66% of the cars we track. On three-year value retention it ranks better than 95% 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.

Best age to buy — around 4 years

A 4-year-old example loses roughly £4,200 a year — under half the £8,450 a one-year-old sheds. The steepest drop is behind it.

Things owners say

  • 01quattro makes it a confident all-weather performer; the turbo six gives effortless real-world pace.
  • 02The Sportback five-door is the practical pick; the coupe is the looker - both subtle next to an RS5.
  • 03Big brakes and tyres mean real running costs; check S tronic dual-clutch fluid history and kerbed wheels.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Audi S5, 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

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 S5 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 S5 as a company car, by tax year and income-tax band. Calculated from a CO₂ of 178 g/km, using £66,000 as the P11D value.

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.

Servicing & the dealer network

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 S5, answered

Is the Audi S5 ULEZ compliant?
Whether a Audi S5 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.
What insurance group is the Audi S5 in?
The Audi S5 sits in insurance group 48 of 50, towards the pricier end of the scale. Your actual premium still depends on age, postcode, annual mileage and no-claims history.
Is the Audi S5 reliable?
Our reliability score for the Audi S5 is 78 out of 100 (good), derived from DVSA MOT records, with a first-time MOT pass rate of about 89% at the reference age.
What economy does the Audi S5 get?
Expect roughly around 36 mpg combined for a typical Audi S5, 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 S5?
On the Audi S5, the issues that come up most by mileage include Tyres & wheels, Suspension and Lighting & signalling. The section above breaks down each one with its typical mileage, repair cost and severity.
How many Audi S5s are on UK roads?

Common questions

Audi S5, answered from the data

Is the Audi S5 reliable?
The Audi S5 scores 78/100 on Forecourt's MOT-based reliability measure, ahead of 84% of the cars we track. That is computed from 31,829 real DVSA MOT test results.
How much does a used Audi S5 cost?
A 2023 Audi S5 with around 24,759 miles is worth roughly £34,550 today (typical range £30,150–£38,950). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
How quickly does the Audi S5 depreciate?
A new Audi S5 typically loses about 30% 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 S5?
The Audi S5 sits in insurance group 48 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 S5?
The most common age-related issues we track for the Audi S5 are: tyres & wheels (typically around 60k-100k miles, £80-£500 to put right); suspension (typically around over 100k miles, £150-£450 to put right); lighting & signalling (typically around over 100k miles, £15-£120 to put right). A full service history and a recent MOT with no advisories are the best protection.
What does the Audi S5 cost to run?
Expect around 36 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.
