What are the running costs?

If you want a conventional petrol or diesel engine, then the Audi Q5 is available with one of each – a 45 TFSI petrol or a 40 TDI diesel. The 45 TFSI is a 2.0-litre turbocharged four-cylinder with 265hp, so it’s not the most economical choice. It offers up to 33.6mpg and emissions as low as 191g/km, although this varies depending on trim level. This model has a 70-litre fuel tank, so a range of nearly 520 miles is possible if you hit that official economy figure.

The diesel has a 65-litre fuel tank and a 24-litre AdBlue tank. AdBlue is a system that helps reduce exhaust emissions, and the tank needs to be topped up every now and again – the car won’t run without it, and the trip computer will let you know when it needs refilling. The 40 TDI has 204hp, while official emissions are as low as 164g/km and fuel economy is up to 44.8mpg. That gives the car a range of up to 640 miles if you can achieve this.

We managed between 40-43mpg during our time with the 40 TDI, which is still enough for over 500 miles per tank. The diesel also benefits from mild hybrid technology that enables the stop-start system to activate sooner, when below 13mph, rather than at a standstill. There is also the ability to coast with the engine off over short distances, which did work quite often with us, and is claimed to function at speeds of up to 99mph.

The two plug-in hybrids have impressive economy figures. Both models feature a 2.0-litre petrol engine with different power outputs. The 50 TFSI e has 299hp and claimed economy of 188.3mpg, while the more powerful 55 TFSI e packs 367hp and 176.6mpg. However, if you don’t plug these cars in regularly to use battery power, then the engines will get closer to 30mpg. Nevertheless, low emissions of 35g/km and 39g/km mean both versions will be appealing company cars.

Quattro all-wheel drive is part-time on the Q5, so the engine predominantly drives the front wheels to conserve fuel, and only sends power to the rear over trickier road conditions. Audi says that the SQ5 will return up to 34.9mpg, while CO2 output is 213g/km. It’s worth noting that the Q5 Sportback returns the same fuel economy figures as the standard SUV, but emissions are very slightly higher. On the plus side, the Audi Q5 is a strong performer when it comes to residual values. Regardless of which Q5 you choose, after three years and 30,000 miles the price guides reckon the Q5 should be worth between 55-58% of its new price.

Servicing and warranty

While the cars themselves might not cost the earth to refuel, servicing at an Audi dealer is going to be expensive – but that’s typical across the premium car spectrum. You can get fixed-price servicing on your Q5, with up to a decade available through service plans. Routine services are reasonably priced, but for out of warranty and rectification work Audi dealers are relatively expensive.

Flexible servicing, recommended for long-distance drivers, can extend intervals up to two years or 19,000 miles. Lower-mileage drivers can opt for slightly cheaper fixed-schedule servicing at one-year, 9,000-mile intervals. Audi uses different formulations of oil for the different programmes. Transmission fluid should be changed every 38,000 miles.


  • Proven mechanical components
  • Well-made; feels solid
  • A few recalls

There have been a few recalls for the current Audi Q5, with a couple in 2019 – one relating to potential wheelarch covers detaching and the other relating to the starter-alternator. Two more in 2020 involved the brake pedal travel increasing on a small number of vehicles and the backrest adjustment mechanism may be faulty on individual front seats.

Virtually every mechanical component has been proven in another Audi or Volkswagen Group car, though, so if any issues arise, parts should at least be plentiful and easy to replace. It’s also true that the first-generation Q5 proved reliable, although it was also subjected to four different official safety recalls.

Audi’s UK warranty is slightly confusing, in that it’s summed up as three years or 60,000 miles, but is actually made up of a two-year unlimited mileage warranty with a free extension to three years or 60,000 miles – in other words, high-mileage drivers with a typical three-year lease or PCP could run out of warranty while still in contract. Extended cover up to five years is available for a reasonable cost.
