Lightweight construction boosts running costs to A3 hatchback levels

A selection of economical Volkswagen Group engines should ensure that the Q2 delivers reasonable fuel economy. If rock-bottom running costs are key, then look to the frugal diesel options – especially the 1.6 TDI.

The entry-level 1.0 TFSI turbo three cylinder has claimed economy as low as 55.4mpg and emissions of 117g/km. That compares favourably with thw Audi A3 with the same engine, as this returns 62.8mpg and 104g/km respectively.

The 1.4-litre TFSI petrol features cylinder on demand technology, which shuts down two of its four cylinders when cruising to save fuel. As a result, the 1.4 is only marginally poorer than the 1.0 TFSI, returning 52.3mpg and emitting 124g/km of CO2. A petrol-powered Mazda CX-3 only manages 47.9mpg, while also emitting 137g/km – so the Audi should prove cheaper to run. However, it's worth bearing in mind that moving up to an S line model with larger wheels pegs economy and emissions back, although in contrast, adding the twin-clutch S tronic auto shaves a little off emissions. Sporty SQ2 models return an official figure of 40.4mpg and emit 159g/km of CO2.

The star of the Q2 range is the 1.6 TDI. Audi claims 64.2mpg and 114g/km CO2 emissions, making this the most economical option if you've got your heart set on a Q2. On test, the combination of frugal diesel, stop-start and tall gearing helped a Q2 return an efficiency figure of 51.4mpg. Again, a 1.6 TDI S line has marginally poorer figures.

The larger 2.0 TDI has economy of 58.9mpg and emissions of 125g/km, which is pretty good when you consider the biggest engine features quattro all-wheel drive and the S tronic gearbox.

Insurance groups

Insurance groups for the Audi Q2 currently start from group 13 for an entry-level Q2 1.6 TDI and 1.0 TFSI SE models. A 1.4-litre TFSI in flashy S line spec sits in group 19. A Mazda CX-3 posts similar figures, with a 2.0-litre petrol SE falling into group 17. 

Depreciation

The Audi Q2 stacks up pretty well when it comes to residual values, with even the most expensive models retaining more than 40 per cent. Those most in demand are set to be the big 2.0-litre diesels, but the 1.0-litre petrol should be a safe buy, too, thanks to predicted residual values of around 48 per cent over three years. The Mazda doesn't perform as well, although all versions still retain at least 39 per cent of their value over the same time period.
