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 40 - 83 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.

If you want to keep Audi A3 running costs down then opt for the 1.6-litre TDI. Claimed average economy is 74.3mpg so expect around 64mpg in real-world driving. Audi servicing can be expensive, especially at main dealers while spares aren't cheap either.

Green credentials

Audi’s greenest A3 is the 1.6-litre diesel with start/stop technology emitting 99g/km of CO2. If Audi A3 emissions are a big concern go for this model: it's also set to be a big hit with company car drivers and private buyers wanting to do their bit for the planet and lower their tax bills.


Audi has an excellent reputation for build quality so worries about Audi A3 reliability should be non-existent. Audi engines are largely bulletproof so you should have few problems with mechanicals.
