2015 Audi A3 Fuel Economy

At 27 MPG combined, the 2015 Audi A3 ranks 2nd of 5 subcompact cars EPA rated for 2015 — 2 MPG better than the 25 MPG median for that group. That places it a little above the middle of its class. Fuel cost is close enough to its rivals that other running costs will probably matter more.

EPA puts annual fuel spend at about $2,750, within $0 of the $2,750 typical for the class — roughly $13,750 over five years.

Across the 7 model years we hold for the Audi A3, the figure ranges from 27 MPG (2015) to 32 MPG (2021), so the 2015 car is best read against its own model history rather than in isolation.

Tailpipe CO₂ is 328 grams per mile. Over 15,000 miles that is about 4.9 metric tons a year, a figure EPA derives from the same test cycle as the MPG above rather than measuring separately.
