Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 26 - 68 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

The Sportback carries a premium over the standard three-door A3 but it does come with the benefits of more luggage and passenger space. If Audi A3 running costs are high on the agenda then the 1.9 TDIe or later 1.6 TDI are the best models, however all cars are quite expensive to service, especially at Audi dealerships. Luckily there’s a good network of independent specialists who will charge you less.

Audi A3 emissions ratings show that this is an environmentally friendly choice for green buyers, especially the small petrol and 1.9-litre diesel engines. The 1.9 TDIe model emits just 119g/km of CO2, but in 2009 this was replaced by an even more efficient 1.6 TDI which emits 109g/km of CO2 and averages 69mpg, making it the cleanest model in the line-up.

The 1.4 TSI model is also frugal, averaging 44mpg and emitting 154g/km of CO2.

‘Typical Audi’ is a phrase you hear a lot, but as the A3 illustrates it does ring true. While you pay a premium for an Audi, the build quality, finish and reliability are all second to none. We’ve heard of no problems with Audi A3 reliability and doubt we will.
