CX 7 and fuel efficiency
Hi all,
I just bought recently a new 08 CX7 GT AWD with Luxury Package. I'm not new to Mazda Town :)...my prevoius car was a Mazda 3 and I traded in for this muscular crossover. I'm loving the power...the turbo...but I'm concerned about the gas consumption... With a full tank a was ble to drive no more than 420 km....mixed city and hightway. I'm using the same gas usd in my Mazda 3 (ESSO Premium 91 octane number). My questio is simple....What is your ful efficiecy wit you CX 7. Thx |
RE: CX 7 and fuel efficiency
This is one of the big issues with this car.
When I purchased my Touring AWD it listed 18mpg city/23mpg highway. But my real world mileage has been 19 combined city/hwy easy or 22 highway easy If my wife drives it in town the mileage will drop to 13 city as she has a lead foot at every light.[>:] I have installed a 3" ETS intercooler and plan on installing a CAI and BOV and a better exhaust. A guy on another forum claims these have boosted his mileage to 24-25 hwy. With a big boost in power too. It just does not seem to deliver the mileage a 2.3 4 cyl engine should when running below 2,500 rpm ie off the turbo boost as one would expect. I have just learned to drive with a very light foot and manually upshift in to higher gears early. And I try not to let the wife drive MY CAR.... :D |
RE: CX 7 and fuel efficiency
Thanks for your answer.
I'm really dissapointed by this fuel economy problem and is only here in North America. In Europe this car has a 13 liters/100 km city driving and 9 liters/100 km highway...and 260 HP with the same engine...but a manual transmision and of course better gas...octan # 95 or 98. The drawback I think is the 6speed automatic and awd. Can you tell me from where you will buy all the extra parts for your car? It won't void the warranty if you will install custom exhaust and intercooler? Any custom chip available on the market (USA & Canada). Another question: do you have automatic front sensing wipers or not...because in Canada this function is not either an option..but in Europe is standard on all models. Thanks again and enjoy an amazing car even it's eating gas like a H3 :D |
RE: CX 7 and fuel efficiency
This is one of the big issues with this car. We've never taken it for a long trip so I don't know what it gets on the highway. How you take-off from a dead stop makes a lot of difference. Coasting as much as possible helps tremendously. My father-in-law has a '08 Buick with real-time fuel consumption updated every 2 seconds. When observiing this, it's amazing how one's driving habits can effect fuel economy. |
RE: CX 7 and fuel efficiency
I've got the 08 CX7 GS 2WD, and I get 300 km per half-tank (i.e. 600 km per tank, projected). I recall the salesman saying that 4WD eats up more gas--maybe it's true! I drive 80% highway.

Thanks again and enjoy an amazing car even it's eating gas like a H3 :D I think the manual transmission and higher octane boosts mileage. Wish I had the manual most days. 1. I obtained my 3" TMIC from ETS directly. 2. I have ordered my CPE CAI from CPE directly and it should be here on the 31st. 3. I am up in the air between a Forge and Turbosmart BOV there are a few sources for each. 4. Exhaust mods will be by my buddy who owns All American Muffler here in town. Cat back custom 3" pipes and twin turbo mufflers The BOV, CAI and TMIC all can be removed in an afternoon before smog or service at the dealer. The exhaust is only cat back so no one really cares. If I did the downpipe and such then there would be an issue. No we have manual wipers front and rear on our car The AWD is really fun on twisty roads ! |
RE: CX 7 and fuel efficiency
Could I get some input on what others are getting for mpg? I just bought my CX7last saturday (2007) and due to my ignorance was missled about the mpg (was told around 27 mpg) and the factory advertises 17/23. I think the car is very nice, and drives very good, just a little concerned over the mpg.

RE: CX 7 and fuel efficiency
My CX-7 does well in warm weather, but hates the cold - summer time I average 25 mpg mixed highway and city driving - on a solid highway trip have done 27.5 mpg in summer - but in cold weather only 22 oh the highway and we won't even discuss the city mpg in cold weather

RE: CX 7 and fuel efficiency
i drive less than 12 miles a day rond trip to work and i average around 17.5 mpg and havent taken many long trips but when i do i get about 21- 23mpg
|
RE: CX 7 and fuel efficiency
Strange car. Best highway mileage was just under 21 in a run from Las Vegas to Los Angeles at mostly 85 mph. In the city, seeming to drive it the same, mileage ranges from 16 - 18.

RE: CX 7 and fuel efficiency
Just went thru my first tank of gas on my new '08 CX-7. The use was 1/2 and 1/2 city and hwy and I averaged 19.7 mpg. There were several hot shoe take offs and high speed passes just to see what the performance was like. I'm so pleased with my new CX, my brother has one and I drove it and really liked it.

RE: CX 7 and fuel efficiency
Sounds about right on your mileage.
I am hoping the CAI will help mileage. But my wifes foot will not let me find out! I need to get a tank though without her driving. |
RE: CX 7 and fuel efficiency
Here is an update...
second tank of gas, bout 40% hwy, 60% city posted 19.7mpg, on regular unlead third tank of gas, nearly 100% hwy, with some hills, just a tick of 23mpg Man, I'm so stoked, a car that looks like this, drives and runs as great as it does and 23 on the highway...all at 70+ I don't drive real hard, but I never drive like 65. I've got to get one of those CAI's Hope you all are enjoying your CX7 as much as I am...8 days and nearly 1000 miles... |
RE: CX 7 and fuel efficiency
Can you convert the 2.3 Turbo MPS engine to run on LPG?
I have just completed 250 miles in a 24 hour test drive of the CX-7. I did a reasonable mix of driving, and covered about 170 miles of sustained motorway miles. I returned an overall average of 22.7 mpg. The drive and experience was truely exceptional. Enough to try and find out if anyone has converted this engine to LPG. |
RE: CX 7 and fuel efficiency
Already over 2 months with this nice and sporty vehicle. The fuel efficiency improved a little bit....just a little...now I'm able to drive 420 km on a tank (city drive). I just contacted the dealer and the best expectations will be 500 km on a tank of gas. Unfortunately I'll void the warranty if I'll modify the exhaust or CAI system. Great car overall I'm really happy...even the gas will jump again this summer to $1,5 /liter

2008 CX-7 GT FWD
Combined City/Hwy - 21 Highway -27 (Warm weather/AC off/70mph max/40psi tires) |
RE: CX 7 and fuel efficiency
I bought my 2008CX7 Grand Touring AWD back in Oct. 2007 and have gotten terrible mileage since. I realize it's a heavy 4 cylinder but the EPA's MPG is way off unless you drive 60 mph on the highway, 5 mph less than the speed limit. I drove from Pitt. PA to Albany NY and got 22 mpg but that's becasue i was in a blizzard and could only safely drive between 55 and 60. I've made the same trip a few times and the average mpg on the highway is about 16 to 17 mpg driving about 75 to 78 mph, not even close to 22 as the epa states, and if the bikes are on top of the car it's aboput 14 mpg highhway. City mpg is about 12 to 13 mpg so needless to say I'm a little put off by the mileage and won't be buying another mazda.

RE: CX 7 and fuel efficiency
Driving full throotlle - cca 450km, driving like grandfather - cca 550km
But thats a known element of the car that is compensated by very good price!!! |
RE: CX 7 and fuel efficiency
p.s.
I think its also the fact that fuel in Europe is of a much greater quality!! Thats a fact. |
RE: CX 7 and fuel efficiency
I purchased a new 2008 GT on 12-3 and other than coming home, it was driven on a rather lengthy trip. On the highway I achieved 19 mpg and in the city I was getting 16. I'm disappointed in the numbers for what under the hood but it is fun to drive.

RE: CX 7 and fuel efficiency
Were I an owner I would improve FE by....
A) "Wiring" the wastegate fully open. B) Milling the head to get a standard "non-boost" DFI compression ratio of 12:1 C) Design a mod that kept the wastegate fully open except at WOT or with a quick/rapid depression of the gas pedal, sort of a reverse implemenation of BA, Braking Assist. (Not compatible with "B") D) Design a variable intake valve delay (Atkinson Cycle Engine) such that a 12:1 "off-turbo" compression ratio could be used and then switch back to 10:1 as the turbo is allowed to come online, boost rises. Note: CAI & BOV are only for those with "boy-racer" mentality and are typically, like K&N, are simply "snake oil" for those that are most gullible. |

ORIGINAL: wwest Note: CAI & BOV are only for those with "boy-racer" mentality and are typically, like K&N, are simply "snake oil" for those that are most gullible. I have both and a larger TMIC as well. As I remove these prior to dealer visits I can honestly say you are full of it. There is such a difference in the power, responsiveness and top end power with these mods over stock. With them I can bark all 4 tires with my AWD touring leaving the line. Try doing that stock |
