2008	4dr Sedan 268-horsepower 3.5L V6 7-speed shiftable automatic RWD	Slow to downshift, so-so fuel economy in the city. Should really have 30 more horsepower. see full Mercedes-Benz C-Class review
2008	4dr Sedan 228-horsepower 3.0L V6 7-speed shiftable automatic RWD	Fuel economy is about averge for this type of car, perhaps a bit less, but not a major deal. see full Mercedes-Benz C-Class review
2004	4dr Wagon 168-horsepower 2.6L V6 5-speed shiftable automatic AWD	The city mpg is usually around 15-17 mpg. Now that's for a hilly neighborhood in a big city, but still. True highway mileage usually about 26 - that's reasonable enough for us. see full Mercedes-Benz C-Class review

TrueDelta Reviews the Real Gas Mileage of the Mazda Mazda3

Mazda Mazda3 Real Gas Mileage: Pros
Year	Comment
2014	Ever since gas guzzling rotary engines almost put Mazda out of business in the 1970s, fuel economy has been a company weakness. The 2013 Mazda3 with a 167-horsepower 2.5-liter engine and five-speed automatic transmission managed only 22 mpg city, 29 mpg highway in the EPA's tests. (The same engine with a manual transmission did even worse, 20/28.) The 2014 with a new SKYACTIV 184-horsepower 2.5-liter engine and six-speed automatic transmission fares much better, 27 mpg city and 37 mpg highway. A $1,600 Tech Package (on the tested car) adds a capacitor-based regenerative braking system that bumps these ratings to 28/38. Quite impressive for a large, fairly powerful four-cylinder engine. The i's 155-horsepower 2.0-liter engine does a bit better still, 30/40, but anyone who cares about driving will gladly trade a 2-3 mpg to pick up 29 horsepower. In my real-world, sub-freezing suburban driving, the trip computer reported a two-way average around 40 mpg when I drove with a feather-light right foot. Push the car harder and high-20s to mid-30s happen. The Focus also manages 27/37 in the EPA's tests, but wasn't quite as efficient as the Mazda in my real-world driving. Others including the 23/35 Dodge Dart GT and 21/29 Kia Forte SX don't come close. see full Mazda Mazda3 review

2014	4dr Hatch 184-horsepower 2.5L I4 6-speed shiftable automatic FWD	Even with the 2.5L 'S' Option, the Mazda SkyActiv tech gives the Mazda3 a very impressive 28/39MPG. The 2.0L standard option gives 31/42. That's pretty standard in most new cars, however the performance for that economy is well above average. Good engines, these are. see full Mazda Mazda3 review
2013	4dr Hatch 155-horsepower 2.0L I4 6-speed shiftable automatic FWD	30+mpg avg since new; starting to improve to around 33mpg per tankful, mixed driving, more town than highway see full Mazda Mazda3 review
2012	4dr Sedan 155-horsepower 2.0L I4 6-speed shiftable automatic FWD	While reviews are mixed, the Skyactiv engine delivers as promised for me. With over 70% city/suburb driving, I've yet to average under 30mpg (odo/pump). Set the cruise control at 65-70 and > 40mpg is easy on a flat highway. see full Mazda Mazda3 review
2012	4dr Hatch 155-horsepower 2.0L I4 6-speed manual FWD	Excellent fuel economy with the skyactiv 155hp engine see full Mazda Mazda3 review
2012	4dr Sedan 155-horsepower 2.0L I4 6-speed shiftable automatic FWD	This car does very well.. I drive mostly highway during the week, but a lot of rush hour driving means lots of stop and go. Even with that and the around town driving I do on the weekends, I am still averaging 38.1 MPG! see full Mazda Mazda3 review
2012	4dr Sedan 155-horsepower 2.0L I4 6-speed shiftable automatic FWD	Hard to beat 40 mpg in a car that drives as well and has the performance of the Mazda3. Most ZOOM ZOOM for the price of any car I test drove. see full Mazda Mazda3 review
2012	4dr Hatch 155-horsepower 2.0L I4 6-speed shiftable automatic FWD	I drive it on the highway at a constant speed of about 78 with the cruise control on, for my daily commute . Very little traffic on my commute, and speed limit is 70. I get about 33 mpg, or 380 miles per tank. I've found that long-range runs of an hour or more seems to burn out the gunk, and I have better fuel economy for the next week or two. I figure driving near 80 is killing the advertised 39 mpg with the Skyactiv engine. see full Mazda Mazda3 review
2011	4dr Sedan 148-horsepower 2.0L I4 5-speed shiftable automatic FWD	great gas mileage even for a lead-foot like myself. see full Mazda Mazda3 review
2010	4dr Sedan 167-horsepower 2.5L I4 5-speed shiftable automatic FWD	I am currently getting 7.7L/100 km in the city and the vehicle only has 2000km on it. see full Mazda Mazda3 review
2010	4dr Hatch 167-horsepower 2.5L I4 6-speed manual FWD	Avg. 27mpg over the past two years. see full Mazda Mazda3 review

2013	4dr Hatch 155-horsepower 2.0L I4 6-speed shiftable automatic FWD	Fuel economy has been OK. I usually do a 50/50 mix and in good weather, I get in the high 7s/100km or about 30 MPG. In the cold weather, it's been closer to 9L/100km or about 26 MPG. Strangely, it's about the same economy I got with my 99 Civic w/ 4 spd auto. see full Mazda Mazda3 review
2011	4dr Hatch 167-horsepower 2.5L I4 5-speed shiftable automatic FWD	22 mpg (city) in a car this small is abysmal. 27 highway is worse. see full Mazda Mazda3 review
2011	4dr Sedan 167-horsepower 2.5L I4 5-speed shiftable automatic FWD	I have the Grand Touring model with the upped engine. Fuel economy is very poor compared to other cars in its class. see full Mazda Mazda3 review
2010	4dr Sedan 167-horsepower 2.5L I4 5-speed shiftable automatic FWD	It sucks (literally). Slightly better than 25 mpg overall (I am driving one with a bigger engine). The 3 i variant would do better without much sacrafaces. But the rating is still below Civics and Corollas of the world. see full Mazda Mazda3 review
2010	4dr Hatch 167-horsepower 2.5L I4 5-speed shiftable automatic FWD	Fuel economy in the VW GTI is slightly better than the Mazda 3, but it requires premium fuel. In the end, it's about even. see full Mazda Mazda3 review
2009	4dr Hatch turbocharged 263hp 2.3L I4 6-speed manual FWD	We average aprox 22MPG. Dont buy the Speed version of the Mazda 3 if your looking for fuel economy. Buy it if you have a smile pasted on your face when you drive. see full Mazda Mazda3 review
2008	4dr Hatch 156-horsepower 2.3L I4 5-speed manual FWD	10.5L avg for 100kms for the 2.3L 5 spd engine. Not as good as some of the competitors. see full Mazda Mazda3 review
2008	4dr Hatch 156-horsepower 2.3L I4 5-speed shiftable automatic FWD	I wish it was better. I get about 23MPG in the city and 27 combined city/highway. see full Mazda Mazda3 review
2008	4dr Hatch turbocharged 263hp 2.3L I4 6-speed manual FWD	Runs premium, burns through fuel fairly quickly with a lot of spirited driving. see full Mazda Mazda3 review
2008	4dr Hatch 156-horsepower 2.3L I4 5-speed shiftable automatic FWD	only 22 MPG highway - with a lead foot. My RAV4 V6 gets the same MPG see full Mazda Mazda3 review
