Audi Q3 SUV - MPG, running costs & CO2

To attract buyers away from less expensive models into a premium car like the Audi Q3, affordable running costs are important. On paper, the least powerful versions of the Q3 should appeal to those with a strict motoring budget in mind, but costs increase sharply with more powerful models. When it arrives, the 45 TFSI e plug-in hybrid model is likely to boast the lowest running costs of any model in the Q3 range.

Audi Q3 MPG & CO2

The entry-level 1.5-litre three-cylinder petrol engine, badged 35 TFSI, manages up to 43.5mpg and CO2 emissions of between 147-163g/km of CO2, depending on the exact spec. Above that is a mid-range 40 TFSI, which returns up to 32.5mpg and 197-210g/km. Both the 40 and 45 TFSI models are only available with an automatic gearbox and four-wheel-drive, but the extra power of the range-topper doesn't hurt fuel economy too much. The 45 TFSI, unavailable on Sport trim, offers up to 31.7mpg and 201-206g/km of CO2, while both these petrols occupy the top Benefit-in-kind (BiK) bracket for 2020/21.

The sole 2.0-litre diesel engine is available with power outputs of either 148 or 197bhp. The former, badged 35 TDI, can be ordered with a manual gearbox and front-wheel-drive, and is easily the most economical. Up to 52.3mpg is promised on entry-level cars, while CO2 emissions are 141-168g/km. The more powerful 40 TDI returns up to 45.6mpg with CO2 emissions of 162-182g/km on Q3s specified depending on the size of the wheels fitted.

Road tax costs £150 a year for all petrol and diesel models, falling to £140 for the forthcoming Q3 plug-in hybrid, unless you cross the £40,000 mark, in which case the car is also liable for the 'expensive car surcharge' of £325 in the first five renewal years.

Insurance

The least powerful 35 TFSI 1.5-litre petrol model has an insurance group 24E rating, which is not much higher than its predecessor. Choose the 40 TFSI 2.0 petrol and it’s insurance group 30E, and the most powerful 227bhp 2.0-litre 45 TFSI petrol is insurance group 36E.

The entry-level 148bhp 2.0-litre diesel attracts a rating of group 26E in standard trim with four-wheel drive, rising to groups 30E and 34E for the 197bhp 40 TDI quattro model in S Line and Vorsprung trim levels respectively.

Servicing

Audi service intervals are based on either a fixed or variable schedule, with the former intended for those who cover fewer than 12,000 miles a year. The latter uses sensors to measure wear-and-tear factors such as oil quality, and the car will notify its driver when it's time for a visit to the workshop. Intervals could potentially be as long as 24 months apart.

Your Audi dealer will be pleased to offer a service package to cover routine maintenance of your Q3, based on your expected annual mileage.

Warranty

Audi offers a three-year/60,000-mile warranty. It can be extended at extra cost, but remains less than generous by comparison to the three-year/unlimited-mileage policies offered by Mercedes and BMW, and even longer warranties offered by non-premium makers such as Kia and Hyundai.
