What Our Members Are Saying about the Real Gas Mileage of the Pontiac G6

Pontiac G6 Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2009	4dr Sedan 164-horsepower 2.4L I4 6-speed shiftable automatic FWD	I opted to get the 4 cylinder 6 speed automatic because of the higher EPA rating and I have a fairly long commute to and from work. see full Pontiac G6 review
2007	4dr Sedan 169-horsepower 2.4L I4 4-speed automatic FWD	Getting 25 city miles see full Pontiac G6 review
2007	2dr Coupe 224-horsepower 3.5L V6 4-speed shiftable automatic FWD	Amazingly it gets 30+ on the highway. I usually drive in stop-and-go traffic but still get 20 mpg easily. see full Pontiac G6 review
2006	4dr Sedan 201-horsepower 3.5L V6 4-speed automatic FWD	Even with a 6 cylinder, and my overzealous driving, I regularly got 28-29 MPG. This is a mix of highway and city driving in a very hilly area. see full Pontiac G6 review

Pontiac G6 Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2008	4dr Sedan 219-horsepower 3.5L V6 4-speed automatic FWD	The V6 I drove had MPG ratings slightly worse than the 4-cyl models I was looking at. see full Pontiac G6 review
2007	2dr Hardtop conv. 217-horsepower 3.5L V6 4-speed shiftable automatic FWD	Not good enough. see full Pontiac G6 review

What Our Members Are Saying about the Real Gas Mileage of the Mazda RX-8

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
2004	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	16-18MPG city, 24MPG highway see full Mazda RX-8 review
