MPG, running costs & CO2 Rating

4.0 out of 5

While its stylish design will attract customers, the Audi Q3 Sportback needs to be economical too - especially as many buyers will upgrade to it from brands that are traditionally perceived as less upmarket. The entry-level diesel and the 1.5-litre petrol available from October, have reasonable running costs but the quickest models are much more expensive to run.

Audi Q3 Sportback MPG & CO2

As you’d expect, the most economical model is the lower-powered version of the 2.0-litre diesel. Badged 35 TDI, it manages up to 47.9mpg and CO2 emissions of 155g/km in a Q3 with front-wheel drive and an automatic gearbox, while ordering four-wheel-drive will increase fuel consumption to 42.2mpg and emissions to 176g/km. The more powerful version of the engine, named 40 TDI, returns just under 40mpg, with its CO2 output shooting up to 185g/km.

The range-topping 45 TFSI 2.0-litre petrol is thirsty; Audi quotes a figure of 31.7mpg. CO2 emissions stand at 202g/km. A 1.5-litre petrol engine has now joined the line-up, with mild-hybrid technology on models with an automatic gearbox. You’ll see around 40mpg and 154g/km from the non-hybrid version, with the hybrid set to be slightly more economical. The 35 TFSI petrol will be the cheapest for company-car drivers, as its Benefit-in-Kind (BiK) rating will be the lowest in the range.


Insurance groups are very similar to the Q3. The 1.5-litre petrol will be cheapest to insure - from group 23 - while the 45 TFSI in Vorsprung trim occupies group 36. This is very similar to the BMW X2, so it shouldn’t be much costlier or cheaper to insure.


When you need to get a Q3 Sportback serviced depends on the number of miles you’ll do in a year. Variable and fixed servicing is available - the latter will apply if you’ll cover less than 12,000 miles in a year, while variable servicing is for higher-mileage drivers and uses sensors to measure oil quality and other factors. If this applies to you, you may find you only need to get the car serviced once every two years.

Audi will sell you a fixed-price service plan, which covers the first two services. As all current Q3 Sportback models (besides the RS Q3) have engines that are 2.0 litres or smaller, you’ll pay £468 upfront or £19.50 per month for 24 months.


Audi offers a three-year warranty with unlimited mileage for the first two years and cover that’s capped at 60,000 miles in the third year. You can extend it for up to five years at extra cost but Mercedes and BMW both offer three years of unlimited-mileage cover. Some of the more mainstream manufacturers, like Hyundai, Kia and Toyota, offer five or even seven years of warranty as standard.
