Audi Q3 review - MPG, CO2 and running costs

Economy figures are decent, while running costs should be appropriate to each model’s performance

Fuel economy is respectable across the Q3 range, that said, if you pick one of the hotter models and drive it hard, you can expect a penalty at the pumps.

The diesel engines are the most frugal, and the lower power 148bhp diesel found in the Sport 35 TDI will reach 48.7mpg on a WLTP test. The punchiest 187bhp diesel engine is capable of returning 40.4mpg - thanks to the 4x4 penalty.

CO2 ratings across the range are average at best. The 148bhp 35 TDI engine with the automatic S tronic gearbox is the cleanest option at 152g/km, although the 35 TFSI Sport auto version isn’t far behind producing 162g/km of CO2. The same engine with manual gears emits 157g/km.

The highest ratings are unsurprisingly for the 40 TFSI and 45 TFSI which emit 208 and 205g/km respectively in top Vorsprung spec. 

Insurance groups

The entry-level 35 TFSI in Technik specification falls into group 23 for insurance, which should mean reasonable premiums. Moving up through the range brings significantly more expensive insurance costs, however. The 227bhp 45 TFSI, in fashionable S line trim, sees a rise to group 33, while the same car with the top Vorsprung equipment level is in group 36.

Those spending between £50k-£60k on the RS Q3 model probably won't be put off by group 41-42 insurance.


The Audi Q3 will hold onto a decent chunk of its original value, with both the standard and Sportback models retaining around 48% of their original value over three years and 36,000 miles of ownership. Diesel versions tend to fare slightly worse, overall, than petrol cars, but only by a fraction.
