What Our Members Are Saying about the Real Gas Mileage of the Acura TSX

Acura TSX Real Gas Mileage: Pros
YearBody/PowertrainComment
2012 4dr Sedan 201-horsepower 2.4L I4
5-speed shiftable automatic FWD		 Average 28mpg over the past 6000 miles of mixed driving. Hit 36 mpg in about 200 highways miles this weekend. see full Acura TSX review
2012 4dr Sedan 201-horsepower 2.4L I4
5-speed shiftable automatic FWD		 Besides price, this was my primary reason for choosing the TSX over the TL. I don't have a lead foot but average about 25-27 mpg overall. On the freeway I'm easily over 30mpg and can run 500 miles on a tank of gas. see full Acura TSX review
2010 4dr Sedan 201-horsepower 2.4L I4
5-speed shiftable automatic FWD		 Surprisingly good fuel economy. Averaging around 27 mpg even with mixed driving conditions and a lead foot more often than not. Beats the EPA estimates easily especially in highway driving where 32+ MPG is possible. see full Acura TSX review
2010 4dr Sedan 201-horsepower 2.4L I4
6-speed manual FWD		 Honda Accord equivalent and a lot more fun to drive. see full Acura TSX review
2010 4dr Sedan 201-horsepower 2.4L I4
6-speed manual FWD		 With 100% highway miles, expect about 30 mpg. I have averaged about 24-25 mpg over 5 tanks in about 50/50 city/highway. see full Acura TSX review
2009 4dr Sedan 201-horsepower 2.4L I4
6-speed manual FWD		 Wonderful...............better than manufacturer quoted. see full Acura TSX review
2009 4dr Sedan 201-horsepower 2.4L I4
5-speed shiftable automatic FWD		 Average fuel economy has been around 28mpg in the city and up to 37mpg on the high, according to the trip computer. see full Acura TSX review
2009 4dr Sedan 201-horsepower 2.4L I4
5-speed shiftable automatic FWD		 32 mpg highway consistantly see full Acura TSX review
2009 4dr Sedan 201-horsepower 2.4L I4
5-speed shiftable automatic FWD		 Better milage than my VW Golf 1.8! Golf is a smaller car, less powerful (great ride though!). Fuel economy with the TSX almost certainly better...given the highway miles I put on. see full Acura TSX review
2007 4dr Sedan 205-horsepower 2.4L I4
5-speed shiftable automatic FWD		 While easy driving, the car runs at very low REVs. see full Acura TSX review

2011 4dr Wagon 201-horsepower 2.4L I4
5-speed shiftable automatic FWD		 Fuel economy for mixed city and highway is not very good for my driving style: between 20 and 23 mpg. I don't drive with the pedal down! see full Acura TSX review
2004 4dr Sedan 200-horsepower 2.4L I4
6-speed manual FWD		 the fact you "should" use premium gas makes it expensive to run as a 4 cylinder car see full Acura TSX review
2004 4dr Sedan 200-horsepower 2.4L I4
6-speed manual FWD		 With my admittedly brick-like right foot, I'm lucky to get 24 MPG in mixed driving, which isn't stellar for a 6MT four-cylinder. (With California premium gas, no less.) see full Acura TSX review

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
