Replying to: arkainzeye (Nov 08, 2006 8:27 am) 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. | |

| 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.
