Just so you know, this is an older review of the 2017-2024 Q5. If you are interested in information about the latest Audi Q5, or news about the current Audi models, please follow the links provided.

There’s a 90kg weight-saving for this second-generation Audi Q5 over the previous model, which helped deliver improved fuel economy and lower CO2 emissions. The other highlight that boosts efficiency is the quattro 'ultra' on-demand four-wheel drive system – which means it stays in a more efficient front-wheel drive mode until the system detects you need the extra traction of four-wheel drive in slippery conditions and engages the rear wheels to help out and get you out of trouble.

Mild-hybrid tech is fitted to both petrol and diesel Q5 models, while the 2.0-litre TDI engine now features a lighter aluminium crankcase and a lighter crankshaft, shaving 22.5kg of weight off the engine.

Audi claims the 40 TDI is capable of 44.1mpg on the combined cycle, with CO2 emissions from 167g/km, while the 2.0-litre TFSI petrol returns up to 33.6mpg, with CO2 emissions from 190g/km.

Low running costs are the order of the day with the 50 TFSI e plug-in hybrid. The 50 TFSI e returns between 156.9–188.3mpg, depending on specification (the Sportback PHEV offers up to 176.6mpg), all the while emitting just 35 to 40g/km of CO2 (again, the Sportback PHEV fares slightly worse with 36 to 41g/km). Of course, you'll have to keep the battery regularly topped up to achieve anywhere near this fuel economy figure, or the 38 miles of pure- electric driving range the Q5 PHEV offers, but the relatively low CO2 emissions will help company car users achieve a lower Benefit-in Kind tax rate.

The 17.9kWh battery pack (14.4kWh useable) of the 50 TFSI e will take around 2.5 hours to fully recharge using a 7.4kW home wallbox.

Insurance groups

Insurance ratings for the standard Q5 45 TFSI petrol range from group 36 to 42, depending on trim level, while the 40 TDI diesel variants sit in groups 33 to 39. The 50 TFSI e plug-in hybrid will generally be more expensive to insure in groups 41 to 44.

Premiums for the Q5 are reasonably competitive when compared to close rivals such as the Mercedes GLC, but they are higher than the BMW X3. A 2.0-litre petrol xDrive20i xLine with 181bhp is in group 30, while the diesel version with 187bhp is in group 32.

Depreciation

The original Audi Q5 was the darling of the premium SUV sector and had rock-solid residuals, but this has since softened. According to our expert data, the Q5 is likely to be worth between 42 - 46 per cent after three years or 36,000 miles, with the 45 TFSI Sport losing the most, and the 40 TDI Black Edition retaining the most.
