Running costs
Audi Q3 running costs
Fuel for a Audi Q3 costs about £1,338 to £1,923 a year, depending on the version, at 7,745 miles a year and today's pump prices. Vehicle tax and the MOT take the yearly bill to £1,593 to £2,178, before insurance, servicing and repairs. That is the mileage Audi Q3s really cover, from their MOT odometer readings, against 6,727 miles for the average car.
- Fuel a year £1,338–£1,923 at 7,745 miles
- Vehicle tax a year £200 registered from April 2017; older cars £225–£445
- MOT £54.85 maximum fee, once a year
- Fuel per mile 17.3p the most economical version
What the fuel costs
Each version's official combined figure, turned into a yearly cost at 7,745 miles and the current UK average of 171.5p a litre for petrol and 198.7p for diesel, from 8,148 forecourts. Figures are WLTP for versions listed between 2025 and 2026.
| Version | Official mpg | CO2 | Fuel a year |
|---|---|---|---|
| Diesel 2.0 4 versions, 2025–2026 | 40.9–52.3 | 141–181 g/km | £1,338–£1,711 |
| Petrol 1.5 1 version, 2025–2026 | 39.2–43.5 | 148–164 g/km | £1,388–£1,540 |
| Petrol hybrid 1.5 1 version, 2025–2026 | 39.8–42.8 | 150–162 g/km | £1,411–£1,517 |
| Petrol 2.0 2 versions, 2025–2026 | 31.4–34.4 | 186–206 g/km | £1,755–£1,923 |
| Petrol hybrid 2.0 2 versions, 2025–2026 | 31.7–34.4 | 186–203 g/km | £1,755–£1,905 |
The spread is worth knowing: the diesel 2.0 costs about £1,338 a year in fuel, the petrol hybrid 2.0 up to £1,905, a difference of £567 a year on the same mileage.
Vehicle tax
What a car pays depends on when it was first registered, not on when you buy it.
- Registered on or after 1 April 2017 £200 a year, whatever it emits
- Registered March 2001 to March 2017 £225–£445 CO2 bands F to K for this model
- List price over £40,000 when new +£440 a year for 5 years
DVLA rates as published on GOV.UK, checked 19 September 2026. Rates change in the Budget. Paying monthly or every six months costs more than a single yearly payment.
MOT and what it tends to find
The test itself is capped at £54.85 for a car, and a Audi Q3 needs one every year once it is three. 17.6% of Audi Q3s fail first time, so on roughly one test in 6 the fee is the small part of the bill.

Audi Q3 running costs: common questions
How much does a Audi Q3 cost to run a year?
Fuel works out at £1,338 to £1,923 a year, from the official economy figures for each version, the 7,745 miles a Audi Q3 averages, and today's average pump prices. Add £200 vehicle tax and up to £54.85 for the MOT and the yearly total is £1,593 to £2,178. That is before insurance, servicing, tyres and repairs, which we have no figures for.
How many miles a year does a Audi Q3 do?
7,745 on average, worked out from the odometer readings DVSA records at consecutive MOT tests. The average car covers 6,727 miles, so Audi Q3s do more than average. It is the reason these costs are the model's own rather than a figure for a notional 10,000 miles.
How much is the road tax on a Audi Q3?
£200 a year for one registered on or after 1 April 2017, whatever it emits. One registered between March 2001 and March 2017 is taxed on its CO2: Audi Q3s fall in bands F to K, which is £225 to £445 a year. Cars with a list price over £40,000 when new pay £440 a year on top for 5 years.
Are the official mpg figures realistic?
The WLTP figures used here are closer to real driving than the older NEDC ones, but they are still laboratory tests. Most drivers see a little less, and short journeys, cold weather and a roof box all cost more than the figure suggests.
What is not in these figures?
Insurance, servicing, tyres, brakes, repairs, parking and depreciation, which is usually the biggest cost of all. We publish figures we can source: fuel from official economy tests and live pump prices, tax from DVLA rates, the MOT from its maximum fee. We do not estimate the rest.

Data sources and methodology
| Figures | Source | Period | Records | Updated |
|---|---|---|---|---|
| Official economy and CO2 | Car fuel and emissions information Vehicle Certification Agency | July 2000 to 15 September 2026 | 172 VCA records | 15 September 2026 |
| Average annual mileage | Anonymised MOT tests and results Driver and Vehicle Standards Agency Derived statistics UK Motoring | 2025 | 140,820 MOT tests | 15 September 2026 |

- Fuel cost is miles ÷ mpg × the price of a gallon, using the model's own average annual mileage and the current UK average pump price. A gallon is 4.546 litres.
- Official economy figures come from the laboratory test in force when each version was sold: WLTP from 2018, NEDC before it. NEDC figures are optimistic against real driving.
- Plug-in hybrid figures assume a charged battery at the start of every journey, so no yearly cost is shown for them. Electric cars are priced per kWh, which depends on where they charge, and we do not publish a charging price.
- Vehicle tax rates are DVLA's, published on GOV.UK and checked on 19 September 2026. The MOT fee is the maximum a test station may charge, from GOV.UK.
- Insurance, servicing, tyres, repairs, parking and depreciation are not included.
