2011	4dr Sedan 330-horsepower 3.7L V6 7-speed shiftable automatic AWD	Fuel economy is abysmal around town. I guess that's the price you pay for going grocery shopping with over 300 HP. However, on the highway it's very possible to exceed the EPA mileage number. see full Infiniti M review
2006	4dr Sedan 335-horsepower 4.5L V8 5-speed shiftable automatic RWD	V8 power--it's a gas guzzler and could've used an extra 1 or 2 speeds more since it revs so high at highway speeds. see full Infiniti M review

TrueDelta Reviews the Real Gas Mileage of the Mazda Mazda6

Mazda Mazda6 Real Gas Mileage: Pros
Year	Comment
2014	This year every Mazda6 has a 184-horsepower 2.5-liter four-cylinder engine under its hood. The 2013's less powerful (170hp) 2.5-liter four managed only 21 mpg city, 30 highway. The 2014 does far better: 26/38 with the automatic transmission and 25/37 with the manual. When fitted with a 178-horsepower 1.6-liter turbocharged four-cylinder engine and manual transmission, the Ford Fusion earns identical EPA ratings. An Accord with a 189-horsepower 2.4-liter and manual transmission checks in lower, 24/34. In real world driving, the trip computer reported averages in the 30s--and as high as 38--in casual suburban driving and about 36 on a 70-mph highway. With such impressive numbers, I'm tempted to place fuel economy higher in the reasons to buy a Mazda6. see full Mazda Mazda6 review

2017	4dr Sedan 184-horsepower 2.5L I4 6-speed manual FWD	I've been averaging over 30 mpg per tank at the pump. Computer usually 1mpg too generous. On some trips I've seen 40 mpgs. My is MT and it is rated considerably lower than AT. But in my book it is good since I've done same mileage in my 2011 Mazda3, which also was noisier, less comforting and generally, smaller car with smaller engine. So, I do about same MPG average and HWY as my 2011 Mazda3 see full Mazda Mazda6 review
2016	4dr Sedan 143-horsepower 2.0L I4 6-speed shiftable automatic FWD	This vehicle is a petrol automatic and the fuel economy is not too bad - around town its pretty good but out on the Motorway at 70 - 80 mph it is hardly any better than my previous 15 year old Volvo S80 petrol automaticwhich had a 5 cylinder 2.4 litre (this is a 2.0 litre less powerful engine) and weighed an awful lot more. Its giving aroun 40 mpg. The istop system seems to be a waste of money - it saves virtually nothing, you have to press hard on the brake pedal to make it work and the miles its claims to have saved are minimal - about 20 in 8,000. see full Mazda Mazda6 review
2016	4dr Sedan 143-horsepower 2.0L I4 6-speed shiftable automatic FWD	The fuel economy on this car is pretty good in my opinion. Its a petrol automatic and if I do half a tank of fuel on Motorways with the speedo at 80 - 85 and the rest of the tank around town I will see 40 MPG. I don;t think one can complain too much about this. If I do all short journeys and no motorway mileage I can probably get around 35, which again is pretty good. see full Mazda Mazda6 review
2014	4dr Sedan 184-horsepower 2.5L I4 6-speed shiftable automatic FWD	Fuel economy is good but not as good as Mazda claims, in 9 months I'm averaging about 28 MPG combined in 60/40 city to highway driving and now in the winter months here in Minnesota, where you need to let the vehicle warm up for a minute or two in cold weather conditions and using winter gas. Still better than most cars in this class and the Skyactiv weight reducing and engine and transmission improvements really do seem to contribute to a fuel efficient car that is still fun to drive and nice to look at! see full Mazda Mazda6 review
2014	4dr Sedan 184-horsepower 2.5L I4 6-speed shiftable automatic FWD	26/38 rating is better than other sedans in its class. Averaging 32 with daily up and down mountain treks. Car maintains speed well and uses little gas keeping speed up. see full Mazda Mazda6 review
2014	4dr Sedan 184-horsepower 2.5L I4 6-speed shiftable automatic FWD	Fuel economy over 71k has been 32.1 MPG. Pretty darn good for a non-hybrid and driving 75-85 mph pretty consistently. see full Mazda Mazda6 review
2014	4dr Sedan 184-horsepower 2.5L I4 6-speed shiftable automatic FWD	I regularly get 33-34 mpg commuting 35-55 mph with some stop and go driving distances of 30+ miles each way. Constant speed driving on interstates through central PA, DC, VA, CT, RI, with seldom slow traffic backups, the car gets 36-37 mpg. Usually set at about 3-4 miles over posted or at traffic flow speeds. see full Mazda Mazda6 review
2009	4dr Sedan 170-horsepower 2.5L I4 6-speed manual FWD	So far seems higher than EPA estimates. Gearing close so that I can drive 30-40 around town in 5ht or even 6th. 6th should be further out to improve mileage even more. see full Mazda Mazda6 review
2009	4dr Sedan 170-horsepower 2.5L I4 6-speed manual FWD	28.5 mpg. Driving to the interstate, taking the interstate to the other side of town, then driving to work (or home). see full Mazda Mazda6 review
2009	4dr Sedan 170-horsepower 2.5L I4 5-speed shiftable automatic FWD	The fuel economy is in the upper range of the norm for this class of car. see full Mazda Mazda6 review

2009	4dr Sedan 272-horsepower 3.7L V6 6-speed shiftable automatic FWD	Well, the 4 cylinder was wonderful, averaging 25mpg, but the large 3.7 seems to be averaging around 21/22...not much better, if not the same, than the Lincoln MKS. But I DO drive this car really hard. Its difficult not to, its so much fun. see full Mazda Mazda6 review
2009	4dr Sedan 272-horsepower 3.7L V6 6-speed shiftable automatic FWD	Hmmm...yes, this is the sore point. But to tell you the truth, I am getting a little tired of pursueing one at the loss of the other. And do enjoy regular gas. see full Mazda Mazda6 review
2007	4dr Sedan 156-horsepower 2.3L I4 5-speed shiftable automatic FWD	I get only 26mpg highway and 19-21 mpg city with 4 cylinder. My other car (toyota solara) do over 33 mpg highway easily even with winter gas. see full Mazda Mazda6 review

2007	4dr Sedan 156-horsepower 2.3L I4 5-speed shiftable automatic FWD	it is very hard to get more than 27 mpg even with all highway drive see full Mazda Mazda6 review
2006	4dr Hatch 215-horsepower 3.0L V6 6-speed shiftable automatic FWD	The only minor complaints I have about this car comes from the engine. It puts out slightly less horsepower than racing engines of the same size, but eats just as much gas, roughly 15% more than I expected from an engine this size. This is something Mazda has drastically improved in recent years, but remains something to watch out for in their larger engines before 2010. see full Mazda Mazda6 review
2006	4dr Sedan turbocharged 274hp 2.3L I4 6-speed manual AWD	26mpg was the most I got on one long trip down south. I drove it mostly highway and usually got 21mpg, even when taking it easy. Around town I got 18mpg. Not great for a 4-cyl engine. My Saab has almost as much power and gets 24mpg around town. see full Mazda Mazda6 review
2006	4dr Sedan turbocharged 274hp 2.3L I4 6-speed manual AWD	Not very good unless you are on the highway only cruising. On the highway it can get 28+ mpg. However, in mixed driving you will be lucky to get 20 mpg. see full Mazda Mazda6 review
2006	4dr Sedan turbocharged 274hp 2.3L I4 6-speed manual AWD	Not necessarily a dislike, just a natural trade off for having 270 horsepower on tap. Averaging 22mpg with mostly city and traffic driving. It actually still bests my old 00 VW Golf turbo, which typically mustered only 20mpg with half the horsepower! see full Mazda Mazda6 review
