Suzuki SX4 MPG Real World Numbers

Curious to hear what new SX4 owners real world MPG numbers are?

  • "Real World" for mine after the first 500 miles is 25.4 MPG. Not as high as I had hoped, but acceptable for colder weather and shorter trips. This with a 5 speed and mostly 2WD mode.
  • So far ours (Auto) has a tad over 2k miles -- when I drive it to work which is about 550 miles round trip per 5 day week mostly highway it nets me about 28 mpg. When my wife drives to work about 45 miles round trip per 5 day week its about 19 mpg (correct mostly city and she is very lucky)

    We also looked at a Honda Fit which has a tad more room and off the line pep. But lacking AWD was a deal breaker and at this price point can't complain. The SUV we traded in netted about 15 mpg no matter who used it so its win for us.

    as they say your millage may vary

    wow i was shocked to read you saying the fit had more pep off the line considering it has a 25% smaller engine! I do believe you though because on the honda hit part of this forum they say its got pep! and its got alot less horsepower than the sx4 .. btw what is the mpg for a fit anyways? i think they are in the 30's for city.?
  • not sure about the fit - we never really wanted it. Due to the fact that we have had a 4x4 for so long and are depended on that feature. And didn't want to spend more then the SX4. As far as power yeah it seems weird that it make a good "number" but feels less? Maybe its just drive-line loss? I'm still thinking Suzuki is using some sort of torque management to reduce power off the line. Cause as soon as its rolling the Sx4 seems very strong for its class.

    You can find out in Honda Fit: MPG - Real World Numbers.

    Honda Fit curb weight: 2400 lbs
    Suzuki SX4 curb weight 2900 lbs
  • and mainly fwd, about 20-25% city, rest Hwy, and he drives 120 miles per day(alittle over 2K right now).
    28+ MPG avg.
    He does drive faster than the speed limit(by about 5 MPH).
    No cruise( he said if he had cruise, adn dorve the speed limit, he could probably hit 30MPG, as advertised).

    Great Car. I hope the rest of the line up, over the next few years, mimics the SX4.... may have to buy a Suzuki myself, then!
  • good feedback... my thoughts were the same at having (wishing mine had cruise); but I think you can actually get "better" MPG with out it on a small egine car like ours. My reasoning is that on slight inclines you will either start going faster sooner to overcome the hill or just give up some speed for a short distance, which saves a tad bit of fuel. Where most cruise system will force a down shift which I think will burn more fuel?

    Then again maybe I tell myself that as no Sports were available - LOL

    since the fit has 500 less lbs of weight. what is the CC (engine size) differences between the fit and the sx4 since the sx4 is heavier.
  • arkainzeyearkainzeye pittsburgh paPosts: 473
    are you saying the sx4 has to get a running start to climb a hill? my tracker with a 2.0 engine (4x4) doesnt have to get a running start to climb a slight hill nor does the engine rev real high either. the tach might jump a tiny bit but thats all. my tracker is only 127hp but i bet it weights alot less. mine is only the 2door.
  • I think you may read my message incorrectly (or I wrote it wrong, very possible)

    Most cars I have owned while using the cruise control on a highway that is not flat, rather hilly. The system will hold you at the selected speed then when the hill comes up speed drops down a bit - maybe 2-4 MPH. Then the system starts to increase gas flow & kicks down to a lower gear to maintain that speed.

    My other car is a Isuzu Ascender with a 4.2L inline six making about 293HP and at 65MPH it turns about 1800RPM. with a slight hill the speed stays the same but in 3rd at about 2800RPM.

    My little Sx4 can climb a steep hill with no worries :-)

    Curious if any of you new owners have experienced a mileage difference between 2wd and auto 4wd? It'll be interesting to see if there is any benefit to the manual system. Those of you up north may have to answer this question.
  • arkainzeyearkainzeye pittsburgh paPosts: 473
    who here has the Optional 4-Speed automatic trany in their sx4? my tracker has the option 4 speed in it and i must say it was worth it! you can turn the 4 speed off to put it into 3 speed mode and wow that engine revs alot higher than when it is in 4 speed mode. my question and comment is what kinda gas mileage you get with the optional 4speed and did anyone see how expensive the sx4 gets when adding the 4 speed? $18,000!!
  • I've noticed that my average fuel mileage begins dropping when I travel at 65-70 MPH on the Interstate vs. a steady 45-50 MPH on rural roads. I expected this due to increased wind resistance at the higher speed, but probably another big factor is the low overall gearing on the 5 speed. After re-fueling and resetting the mileage computer, I was up to a 33-34 MPG average driving at a steady 45-50 MPH on a level rural road for a distance of about 30-40 miles. This included some traffic lights, stop and go, etc. After getting back on the Interstate and driving about 65 MPH, I watched the average mileage drop to 28.9 MPG after about 60 miles of driving and it was continuing to drop slowly. I think the highway rating of 28 MPG is pretty darn accurate. I believe you could probaly average 30 MPG with careful driving at 50-60 MPH or so, on level country roads. Some have questioned the accuracy of the onboard mileage computer, but it should know the exact mileage since the ECU knows exactly how much fuel it is sending to the fuel injection system, right down to the duration in milliseconds for each pulse of the injectors. The only variable I see might be in the rolling circumference of the tires which is subject to variation due to inflation pressure. The biggest variable in calculating your own mileage on a car with this small of a fuel tank is the accuracy in getting the tank filled the same each time. I haven't run with the AWD in "Auto" much yet, but I do know that the drive shaft is disconnected when you are in "FWD" so there is probably some reduction in drive train loss running in that mode.

    "I do know that the drive shaft is disconnected when you are in "FWD" so there is probably some reduction in drive train loss running in that mode."

    It is also disconnected all the time in AWD unless there is front wheel slippage, because all you do by putting it in AWD is "turn on" the rear electronic clutch pack. Nothing is physically engaged, though, until the computer detects wheel slippage.

    thats exactly what i thought. that switch is a Gimmick. The only real advantage or purpose to that switch wouldbe to put the sx4 into a Low range or (lock) setting. other than that the fwd and awd is useless, you might as wel just be in awd. this way you get the same fuel economy and if you ever needed it you wouldnt have to remember to hit the switch. So the switch should really read 4low/low range or something to that nature, as the fwd is useless. I think it might give a faulse sense of better fuel economy? Who knows maybe suzukis reseach shown that people like to pressure button?
  • I thought the drive shaft was disconnected in 2wd because when I had one back wheel jacked up, I could turn the wheel and the drive shaft didn't turn. Today I rolled the car a bit with the key on in both FWD and AUTO and the drive shaft turned in both modes. Evidently the drive shaft is being driven by the front differential. I've read that the center differential is located in the rear axle. I would like to know more about how this system engages and disengages. I did drive in some snow today and you can definitely feel the rear drive engage when when the front wheels start to spin. FYI the SX4 does not have a 2-speed transfer case so there is no low range or 4 Low.

    Interesting. I'd be curious to see technical details on how this system works. You really don't feel much of a transition with Subaru's AWD system, either auto or manual.
  • arkainzeyearkainzeye pittsburgh paPosts: 473
    you said there isnt a 2 speed transfer case. is there a 3rd switch? fwd, awd and i thought there was something else that you cant drive fast with..
  • arkainzeyearkainzeye pittsburgh paPosts: 473
    with my chevy work van (awd) you can surely feel when awd kicked it. if your on icy roads it sounds like a brick hits the frame. in snow its more like a Clunk! With the chevy van there is No switches. it just knows when it needs more traction and engages.
