Audi engineered a 90kg weight-saving for the second-generation 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.

A facelift in 2020 saw Audi include mild-hybrid tech for both petrol and diesel Q5 versions, 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 and 55 TFSI e plug-in hybrid models, although the latter is no longer offered on the Q5 price list. 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 more powerful 55 TFSI e returns a claimed 156.9–166.2mpg, with CO2 emissions of 40-42g/km. It’s a great choice if you regularly switch between shorter urban commutes and longer journeys, with around 26 miles of all-electric range possible in this version.

Insurance groups

Insurance ratings for the standard Q5 petrol versions range from group 32 to 42, depending on trim level, while the diesel variants sit in groups 28 to 38. The plug-in hybrid cars will generally be more expensive to insure as they are in groups 40 to 43.

Premiums for the Q5 are reasonably competitive when compared to close rivals such as the Mercedes GLC. A 2.0-litre petrol GLC AMG Line with 254bhp is in group 36, while the diesel version with 192bhp is in group 32.

Depreciation

The original Audi Q5 was the darling of the premium SUV sector and had rock-solid residuals that broached the 60 per cent barrier. With the introduction of plenty of rivals, values have softened a little, but it still manages to hold onto around 56 per cent of its value over an average three-years/36,000 miles of ownership.

Although you'll pay more to access the performance of the SQ5 model, it's a stronger used bet, retaining around 65 per cent of its original list price after the same three-year period.
