Audi Q5 - MPG, emissions & running costs

Every Audi Q5 features hybrid technology. For the moment, it’s only mild-hybrid assistance, however Audi’s latest ‘MHEV plus’ 48-volt system allows for short bursts of pure-electric driving at low speeds – around town, for instance – which helps boost fuel efficiency and reduce CO2 emissions, compared with non-electrified engines.

Audi says the 2.0-litre TFSI mild-hybrid petrol engine in the Q5 can return up to 39.2mpg. During the international launch for the car, which included a fair amount of driving on twisty back roads, we managed to average 32.1mpg.

Naturally, the 2.0-litre TDI mild-hybrid diesel engine should be more frugal, with the brand claiming it’ll average 45.6mpg. We’ve not tested this version long enough to get a real-world efficiency figure, but hopefully will soon. 

The final engine option for now is a twin-turbocharged 3.0-litre mild-hybrid V6 found exclusively in the SQ5. Supposedly, it’ll return up to 34mpg, however after our testing the trip computer showed just 22.4mpg.

Plug-in hybrid, or TFSIe, versions of the Q5 will be available later this year, featuring a 25.9kWh battery that will offer more than 50 miles of pure-electric driving range, we’ve been told. However fuel efficiency stats for the PHEVs are still yet to be announced.

Tax 

Given that prices for the Audi Q5 start from over £50,000, it means every model is subject to an additional surcharge on annual Vehicle Excise Duty (otherwise known as road tax), which is applied from the second time the vehicle is taxed until it is six years old. 

Depending on the exact trim level, petrol and diesel Q5s fall into either the 36 or 37 per cent Benefit-in-kind tax bands for company car users. The forthcoming plug-in hybrid versions will attract much lower ratings, possibly as low as eight per cent.

Depreciation

According to our latest expert data, the new Audi Q5 will retain between 54-56 per cent of its original value after three years of ownership and 36,000 miles. However that’s the standard SUV, while the more expensive Q5 Sportback is supposed to hold onto 47-49 per cent of its list price. For comparison, the BMW X3 is supposed to retain between 54-59 per cent, while the Mercedes GLC is predicted to retain 39-58 per cent, with AMG versions set to lose the most value.
