Fuel economy is great. The car gets about 33-35mpg in spirited driving and can do up to 42mpg if driven economically. I would prefer a manual transmission but the automatic performs very well for a commuter car. I always use 87-octane gas, Royal Purple synthetic motor oil and a K&N reusable air filter in the stock intake. I have a sub in the trunk and heavier speakers upfront that probably cancel out the mpg gains from the oil/filter. Worth it to me. Undoubtedly the cars aerodynamic car- forward design contributes to its fuel economy as well, but the thick pillars front and rear cause large blind spots making lane changes a bit more risky than Id like.
