TrueDelta Reviews the Real Gas Mileage of the Audi A3 / S3 / RS3

Audi A3 / S3 / RS3 Real Gas Mileage: Pros
YearComment
2016 For a car that can get from zero to 60 mph in under five seconds, the Audi S3 can be quite economical. The tested 2016's EPA ratings were 23 mpg city, 31 mpg highway. For 2017, the S3's ratings have fallen to 21/28 for no obvious reason. Maybe the updates pushed the car into a higher test weight class. I doubt the car's real-world fuel economy has changed. I observed 25 mpg in suburban driving (with a light foot) and nearly 30 mpg on the highway. Despite its more powerful engine, the Mercedes-AMG CLA45 scores even better than the 2017 S3 (if not quite as good as the 2016): 23/30. see full Audi A3 / S3 / RS3 review

I am getting 30+ MPG in mixed 50/50 city/hwy driving. Hwy MPG if <70 MPH is easily 34 MPG+. If it had 7 gears, MPG at 70+ would be far better. see full Audi A3 / S3 / RS3 review
