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

Audi A3 / S3 / RS3 Real Gas Mileage: Pros
Year	Comment
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

Mazda RX-8 Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2009	4dr Coupe 232-horsepower 1.3L R2 6-speed manual RWD	One of the big downsides of the rotary is truly horrendous fuel economy. When the RX-8 first came out in the early 2000s, its mileage ratings of 16/22 city/highway mpg (stick shift) were just barely acceptable, but there days, with many crossovers hitting more than 30 mpg on the highway, those figures are truly atrocious, especially given respectable but certainly not neck-snapping power. Futhermore, it takes premium. If you're using the RX-8 as it commuter, fuel costs will add up quickly. In my predominantly around-town driving, I typically average between 16-17 mpg. My highest recorded average was 20 mpg on a highway trip at speeds around 75 mph. see full Mazda RX-8 review
2007	4dr Coupe 212-horsepower 1.3L R2 6-speed shiftable automatic RWD	The EPA numbers are way low compared with my real-world experience. The window sticker showed 18/25 and I have never seen less than 23 with my 40/60 city/highway commute. I think Mazda should develop a lean-burn economy cruise mode for this car. see full Mazda RX-8 review
2006	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	Lite bit to high consumption when I drive it in normal speed. On full woot its ok. see full Mazda RX-8 review
2005	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	Worst fuel economy in its class. see full Mazda RX-8 review
2004	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	Not that bad for what it is, but it seems to me that Mazda's Sky Active technology could help the city mileage. It just needs more R&D. see full Mazda RX-8 review
2004	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	At 16 m.p.g. on premium grade these days it could be cheaper to take a taxi. see full Mazda RX-8 review
2004	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	For a small engine displacement and a relatively light vehicle weight, the gas mileage is weak. I usualy get around 19mpg, and that does not realy matter if I am doing all city or all highway driving. I think the real problem is in the sixth gear it isnt much different than fifth gear so it does not provide good fuel economy. see full Mazda RX-8 review
2004	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	For a car with a 1.9 liter engine I would have expected better than 16-19 MPG. Get your foot into it and the numbers fall drastically. Otherwise I loved that car. It just got too small with a newborn and a big dog. see full Mazda RX-8 review
2004	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	I gets 20MPG no matter what I do. Running around 20. 1/2 highway 20. All the highway all day 25-26. I think that it could do better. see full Mazda RX-8 review
