Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.
Based on "Weighted" mpg; figures depend on the proportion of miles driven in pure electric mode and may vary widely

  • Audi Q3 shouldn’t cost the earth to run
  • Diesel engines should be more consistently economical than petrol
  • Different wheel size and Quattro all-wheel drive impacts fuel economy

All models have been tested with WLTP in mind, but despite that, the mpg figures have changed dramatically during the Q3’s lifeline as they’ve been updated, with some engines seeing a drop of 10mpg since launch.

The 1.5 TFSI petrol – badged 35 TFSI – has cylinder-on-demand technology which shuts down two of the four cylinders to maximise fuel when they are not required.

With the automatic gearbox, this achieves between 38.7-41.5mpg depending on the model.

Opt for the manual gearbox and this dips down to 39.2-42.2mpg depending on Sport or S Line models.

Work your way up to the more powerful engines and the 40 TFSI achieves between 30.4-32.5mpg depending on model, with the drop in fuel efficiency partly due to its Quattro all-wheel drive system.

The 45 TFSI drops a little further with 31-31.7mpg on depending on S line trim and Vorsprung trim level.

Opt for the 35 TDI diesel and this varies between 39.2-42.2mpg with the manual gearbox, and improves with the automatic, achieving 44.8-48.7mpg.

The more powerful and automatic-only 40 TDI achieves between 38.2-40.4mpg on S line models and 37.7mpg on Edition 1 and Vorsprung.

The fuel tank varies between 58-60-litres in size depending on model.

When it comes to CO2 emissions, Sport models are the cleanest due to their smaller wheels:
The 35 TFSI emits between 155-167g/km of CO2 with an automatic gearbox and 153-168g/km with a manual gearbox.

The 40 TFSI ranges between 197-210g/km, while 45 TFSI is actually less on certain models at 201-207g/km.

The 35 TDI emits between 175-187g/km with a manual gearbox, but fares better with an automatic, dropping down to 153-167g/km.

The 40 TDI fares worse with figures of 184-198g/km.

  • Previous Q3 proved to be a reliable car
  • Shares mechanical parts with other models
  • Too new for any recalls

The Audi Q3 shares the same platform and majority of its components with the Audi A3, which has experienced three recalls to date. The previous Q3 was subjected to two recalls throughout its lifetime, which is quite low.

That said, there is more onboard tech this time, so hopefully this won’t throw up too many electrical gremlins.
