Mazda RX-8 Real Gas Mileage: Cons
YearBody/PowertrainComment
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

2012 4dr Sedan 292-horsepower 3.6L V6
8-speed shiftable automatic RWD		 I average 31Mpg highway, 'nuff said. see full Chrysler 300 review
2012 4dr Sedan 470-horsepower 6.4L V8
5-speed shiftable automatic RWD		 This car has a 6.4-Liter V8 engine which produces more horsepower and torque than you'd ever need for any passing situation or any driving situation. That is, unless your las t name is "Andretti". The first of the 2nd gen 300 models I drove was the 390HP V8 in the AWD model, followed by the Pentastar V6. see full Chrysler 300 review
2011 4dr Sedan 292-horsepower 3.6L V6
5-speed shiftable automatic RWD		 I am light footed when it comes to driving and this car with the 3.6 will return very favourable fuel economy when treated as such. This car had 500 km when I purchased it and now has 1800 km and highway mileage is consistently at 7.3 L/100Km. see full Chrysler 300 review
2005 4dr Sedan 340-horsepower 5.7L V8

YearBody/PowertrainComment
2009 4dr Sedan 250-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Average 23mpg overall. Temperatures under 30 degrees and the AWD is always on and got 19mpg on the highway. Not bad for a 4400lb car, not good if you pay for gas. see full Chrysler 300 review
2008 4dr Sedan 250-horsepower 3.5L V6
4-speed automatic RWD		 I am not impressed with the fuel economy that my car gets. It only gets 22-24 mpg. The sticker states 26-28. I get that it is a bigger, heavier car, but they need to be more honest and realistic about the mpg. see full Chrysler 300 review
2008 4dr Sedan 250-horsepower 3.5L V6
4-speed automatic RWD		 I get about 20-25% worse fuel economy than EPA specified in the city, although on the highway I do 5-10% better, despite my occasional lack of regard for the posted speed limit. see full Chrysler 300 review
2008 4dr Sedan 178-horsepower 2.7L V6

2006 4dr Sedan 340-horsepower 5.7L V8
5-speed shiftable automatic AWD		 From a social conscious view the 19 MPG AVG is poor, especially with gas costing $4 a gal. But face it, considering the performance you get... I can live with the guilt and high cost of driving. see full Chrysler 300 review
