  • TFSI e plug-ins will attract company car buyers
  • The SQ5 is expensive to run - but also very quick
  • Excellent resale values reduce cost of ownership

From the regular Q5 range, there's just one diesel and a single petrol engine - the 40 TDI and the 45 TFSI, respectively. The 40 TDI claims a best mpg figure of up to 39.2mpg, while CO2 is rated at 189-196g/km. The 45 TFSI offers just 31.7-33.2mpg, while CO2 emissions weigh in at 193-203g/km. 

The SQ5 switched from powerful V6 petrol to powerful V6 diesel, and with it have come some more attractive running costs. Audi claims it'll return up to 32.8mpg, while CO2 output is 225g/km. 

Finally, the 50 and 55 TFSI e plug-in hybrid variants claim the most impressive fuel economy and CO2 figures. The 50 TFSI e offers up to 117mpg, with CO2 emissions of 55-62g/km, while the 55 TFSI e claims up to 108mpg and 59-60g/km. While these figures certainly sound appealing, if you don't plug the car in regularly and use it on battery power alone for the majority of your journeys, you'll be getting closer to 30mpg as it's a powerful petrol motor. Nevertheless, both will be appealing from a Benefit-in-Kind tax perspective for company car drivers. 

Certainly from a miles per pound perspective, there's not such a stark difference between the cheapest and dearest Q5 with a range of 6.6 - 9.0 mpp.

While the cars themselves might not cost the earth to refuel, servicing them at an Audi dealer is going to be expensive – but that’s typical across the premium car spectrum. Also be aware that as you upgrade the wheel size, tyres become more expensive.

It’s not all bad news – far from it – especially when it comes to residual values. Regardless of which Q5 you choose, after three years and 30,000 miles it should be worth between 55 and 58% of its new price.

How reliable is the Audi Q5?

  • Proven mechanical components
  • Well-made; feels solid
  • Previous Q5 subjected to four recalls

It’s a case of so far so good for the current Audi Q5 – not being subject to any recalls since launch in 2016. 

Virtually every mechanical component has already been proven in another Audi or Volkswagen Group car, while those elements that have been introduced on the Q5 are essentially developments of technology seen elsewhere already.

It’s also true that the first-generation Q5 proved reliable, although it was subjected to four different official recalls according to the vehicle inspectorate, the DVSA. Maladies included a potentially shattering sunroof, a loss of braking performance and a potential fuel leak.
