While I have only had my UltraGauge for a few days at this point I have some interesting numbers for y'all. First off, I have already calibrated the UG Odometer over a ~170 mile trip using my TomTom and my iPhone both of which are accurate to .01 miles. Then I did an additional 156 miles to calibrate the UG's fuel usage gauge which was then followed up by a 54 mile trip to verify the accuracy of the both gauges.
This morning I watched the fuel usage gauge that resets every time I start the car and I watched my car burn .21 Gallons in the first 1.90 miles(averaging 41 MPH). The car then proceeded to burn an additional .74 Gallons over the next 30.38 miles (averaging 64 MPH). These numbers are significant because for my commute I got an average of 33.98 MPG but if you take out that warm-up period I would have gotten 41.05 MPG. Also that means that if my daily commute was 47.9 miles I would average 36.01 MPG. In summary, the CVT has a warm-up period ranging from 1.7 to 2.1 miles depending on the temperature of the transmission. It will try to hold at or above 2K RPM for the entire warm-up period. So to minimize the impact on your FE try to get up to 45-50 MPH for for the initial warm-up period and then proceed to drive normally. Also combine your trips as much as possible because every time you let the car cool down for extended periods of time you are almost guaranteed to burn 1/5 of a gallon on your next trip. |

This AM the temps in Rochester, NY were 27*F. Before heading to work, I drove 2 miles to my favorite gas station to fill up and check my tire pressure. I then zeroed my trip odometer, which reset the AVG MPG display, and drove to work (which is mostly highway, although I did run into some rush-hour traffic jams along the way). By the time I arrived at work 18 miles later, my AVG MPG display showed 33.6 MPG. The key to that good MPG reading was the 2-mile warm up the car received before I zeroed out the trip odometer. I'm confident that if I zeroed the trip odometer in my driveway when the engine was stone cold, rather than at the gas station 2 miles away, my AVG MPG display would have shown significantly worse results. So while it may take 10 to 20 miles for the engine/tranny to reach full operating temps on a cold day, the highest gas consumption comes during the first couple of miles of warm up, and then starts improving from there. This is why lots of short trips that allow the car to cool off between each trip will result in an awful MPG result. |

You must have missed the part of IveBeenRued's post that included the following relevant information:
See, that isn't hard to read and break out the important information, it was just cleverly hidden in the other words he/she wrote. So how is your warranty complaint about Subaru providing misleading MPG figures for the CVT Impreza going for you? Did SOA offer to settle and cut you a check yet? Is the EPA launching an official fraud investigation? Did Consumer Reports retract their endorsement for our fuel sipping AWD best buy? inquiring minds want to know (at least I do) |

Well this def explains my 22-24 city Average. bah.. oh well.. I think I can live with that. Next tank I do will be completely lead footed just to see how horrible things can be. I'll be expecting 250mi on that tank or less... |

Electric cars and hybrids do best in short drives like you have, some of them can use mainly electric if you keep your drives consistently short. Last edited by Zeeper; 12-06-2012 at 03:05 PM. |

I'll either be buying on of those as a secondary car down the road or wishfully holding for for a Subaru hybrid within the next 5 years lol |

now you are using my argument that an AWD vehicle will NOT achieve the same MPG as a FWD vehicle. maybe you should make up your mind because the more you try to arque whatever your problem is the more toolish you become. the Impreza is an AWD (all 4 wheels are drive wheels) vehicle, it will not perform the same as your ****ty toyota corolla which let me remind you weighs in at 900 lbs less and is a FWD drive ( that is the front 2 wheels only) and it has less HP, obviously even if they are rated the same the corolla will achieve better mpg. i realize this is a very difficult concept to understand. most vehicles on the road do not achieve their rated MPG at speeds faster than 60mph, yes there are exceptions (your ****box for example) but the majority of vehicles do not. again very very difficult concepts to understand here. Social skills must be difficult for you as you don't even understand when someone mocks you Last edited by flyboy1100; 12-06-2012 at 01:01 PM. |

So you're upset that the EPA doesn't do the highway test at 80mph? The EPA rating is at the EPA speed. Engine displacement, tuning, gearing, and aerodynamics vary from car to car and the gas mileage at speeds greater than the EPA test will vary accordingly. |

My wife does that "test" regularly in our 2012 CVT hatch Impreza, well past "broken in". The overall MPG gauge holds a pretty steady 20mpg. She is a lead foot, and her commute and a large percentage of her driving is under 3 miles per trip. Occasionally she does just the short hops for awhile and it can get down to 18mpg. 18-20 mpg is identical to what my 2003 Honda Element AWD gets under the same circumstances. On the other hand, the best my Element can get is 22-24mpg freeway, whereas I can get 36-38mpg summer highway driving, with the Impreza, including mountain roads, when I borrow it to do long drives to hikes. I don't think anyone is debating the freeway mileage possibilities of the Impreza. But the short hop city mileage is mediocre, at best, even when compared to similar AWD cars, driven in a similar way. The Element is not light or aero. The Impreza requires a definite creative definition of "city" and very very careful driving to get the city rating with a CVT.(can't speak to the 5 speed.) On the other hand, its a lot more fun to drive than my Element. |

The shorter the hop, the more a block heater will help.

On the freeway I get numbers in line with the estimates. The somewhat crappy city numbers don't bother me much since I enjoy driving the car and a tank still lasts me a long time if all I'm doing is commuting. Edit: I had an '11 Impreza CVT loaner for a couple of weeks and it got 18-19 MPG on the same commute. Was much less fun to drive, too. |

Last tank of gas on the car was probably the worst I've had so far, right around 24 MPG. Literally only got 250 miles on the tank, with only one bar still on in the fuel gauge. But consider that (1) it's winter blend gas, (2) the entire tank was short hops to and from work (8 miles one way, last half going traffic signal to traffic signal at 30 MPH), (3) I've been driving the car a little more 'aggressively' lately, and (4) outside temps have been cold. But no issues, as I expected this based on the items noted above. Once you've driven the car for a while and experimented a bit with how you drive and where you go, it becomes extremely predictable what kind of MPG's you're going to get.
Honestly, the sticker is fairly accurate. I can reproduce those numbers if I try, and overall, I'm not far off the combined rating for all of my driving. And I certainly won't complain, since for an AWD car, the mileage numbers are great. For those who like the details, '12 Premium, CVT, just under 11k miles, and no oil consumption noted. |

If you folks have an interest I have made a first attempt at statistics from the fuelie.com website provided earlier. Given the format for blogs makes tables difficult, if someone can guide me on how to post graphs as pictures I would be willing to make them and post. Fueli.com had 220 2012 Imprezas where I was able to extract transmission type, state (in a very limited number of cases), average mileage, last mileage, best mileage, total miles driven, and % city driving. Should be an interesting analysis as long as most are willing to accept the data as representative if imperfect. Additionally if there is a particular question to be answered we can ask the data to attempt an answer.
I am also willing to share the Excel spreadsheet if there is an interest. |
