It doesn't matter that "no one drives like that". What matters is that they drive the same in different cars. As we have seen with Consumer Reports, there is a tight grouping of vehicles that all get, with the admittedly easier Consumer Reports test, 35 mpg. All but one of those got very close to the same EPA ratings. There was bias error but not much random error. +/- 2 mpg is pretty close. The problem was that of the 13 cars, only 12 within 2 of the average. The other was 6 mpg off, so that with the other the mpg claimed would make it very difficult to get the EPA mpg. There are, BTW, only two types of error - bias error and random error.
So, 12 cars were rated at 30 mpg highway by the EPA test, and 35 mpg with the Consumer Reports test, within 2 mpg. Those cars could easily get their EPA highway mpg, just as we know it's not that difficult to get 30 mpg in a CVT Impreza. (Well, those of us that have CVT Imprezas. Those that don't have one are just talking out their ____) That's all those other cars that get the same real world mpg as the CVT have to do. That's not really a difficult concept to understand, so I don't get why there are people still arguing that the Impreza, rated at 36 but performing the same as the other cars in terms of real world mpg, is not off in its EPA estimate. Somebody did a comparison test with Fuelly, but only used 7 or 8 of each fill in the other cars so I'm not real confident in that. It's easy to get 30 mpg by all 13 of those cars. All but 1 of the 13 then easily get their highway EPA rating. All but the Impreza. http://forums.nasioc.com/forums/show....php?t=2477627

No. I wish I could be 87 octane E0 gas, but I can't. My source for E0 (Fastrac) only sells E0 in its premium gas. Their 87 and 89 octane products are E10. So I pay more for my gas than I'd like to, since the Impreza doesn't need anything more than 87 octane.
The higher octane doesn't hurt anything. It's just not necessary in the Impreza, and is a waste of money. However, I get approximately 10% better fuel economy with the E0 gas, which makes up for the higher purchase price. Last edited by sgoldste01; 03-11-2013 at 07:50 AM. |

This 10% difference is exactly what the majority of modern vehicles should be seeing on the winter blend of fuel in the Northeast. I would love to try E0 but like I said it isn't anywhere near where we live. Summer blend should be here some time in April.

And that, my friends, is the difference between 30 MPG highway vs. 36 MPG highway. Furthermore, I'll bet you a beer that when Subaru ran their EPA tests, they were using summer blend E0 gas. In warm weather. With the A/C off. On a windless day. And properly inflated tires. And so on, and so on. FYI, I prefer unfiltered wheat beers, like Shock Top or Blue Moon. |

I find it amazing that we have to make so many excuses for this car not reaching the epa estimates. With previous cars I have owned I never was concerned with the fuel that I used, or having perfect tire inflation, or driving exactly as the epa test was done. I could always just start the car and drive which would result in very consistent fuel economy that did not sway more than 10% from the epa numbers. This car requires me to take everything into consideration in order even come close to the epa numbers.

I made a 60 mile trip yesterday, had it read 37 mpg on the dash. Cruise control at 60 mph, straight, long, relatively flat road.

Well the one car I can vouch for is the new skyactive mazda 3. My friend owns one and is consistently getting 30+ mpg on his weekly 10 min. commute to work. So I would say that one is not included when you say "many of the new cars".

Yes with THIS car that is what you need to do. That is why I will not recommend the Impreza to others if fuel efficiency is important.

its also fwd He could probably get higher mpg in your car Also everyone should check their tire pressure irrespective of what car they drive, I would greatly appreciate it as would the environment. check tire pressure weekly or every 2 weeks. Buy a bike pump or an inflator from walmart. pressure varies based on temp I check oil level, coolant level, brake fluid, and tire pressure weekly. You should also check around the engine area to make sure everything looks A OK. lets all do our part http://www.amazon.com/Joes-Racing-32307-Pressure-Gauge/dp/B00404WDUC/ref=sr_1_sc_1?ie=UTF8&qid=1363011657&sr=8-1-spell&keywords=jores+tire+gauge |

i have stated it numerous times, the testing procedure is flawed, it really hasn't been updated since when it was introduced, just minor changes but overall the procedure looks like it is the same as it was 35+ years ago. Quote:

Class Action?
I know it's hard to hear, but Subaru used MPG Fraud on the Impreza for one reason, to sell more cars.
Below is a list from Consumer Reports best economy cars for 2013 in Wagons and Hatchbacks(clickhere) The last 4 on the list either matched or were below the EPA estimate. 3 of those 4 have been or are now in class action lawsuits. Hyndai/kia last year reduced their EPA from 40 to 37, and is issuing rebates based on a ClassAction (clickhere). Ford C-max is currently in a Class Action (clickhere). Table taken from CR's best milage Wagons.(clickhere) CR real world vs EPA (highway values only) Sorted by amount over EPA estimate. CR/EPA 49/41 +8 Jetta SprtWgnTDI(MT Diesel) 47/40 +7 Toyota Prius V Three 36/29 +7 Toyota Matrix S (2.4) 36/31 +5 Toyota Matrix 1.8L 33/28 +5 Kia Soul Plus 37/34 +3 Mini Cooper Clubman 33/30 +3 Nissan Cube 1.8 S 39/37 +2 Ford Focus SEL xx - - - - - - - - - - - - - - - - - - 37/37 +0 Hyundai Elantra GT 36/36 +0 Kia Forte EX 33/36 -3 Subaru Imp Spt Premium 38/47 -9 Ford C-MAX Hybrid SE ============================================= I might also add all other Subaru's CR test beat EPA. 37/30 +7 Subaru BRZ 29/25 +4 Subaru Legacy 3.6R LTD 35/32 +3 Subaru Legacy 2.5i Prem 32/30 +2 Subaru Outback 26/24 +2 Subaru Forester 2.5 XT ltd 23/21 +2 Subaru Tribeca LTD 3.6L 28/27 +1 Subaru Forester 2.5X Prem 34/33 +1 Subaru Crosstrek XV |

I hope you guys complaining to Subaru force them (or EPA?) to hand out a gas stipend to accomodate for the 1mpg off from EPA estimates.
My boss has a 2011 hyundai that this happened to and says whenever he goes to dealer they reimburse him the amount owed. So in one year he was able to claim around $100 or so. I achieve the EPA estimates but if I can get gas money on top of that for the life of the car, Im in. lol Keep fighting the good fight lol |

Personally, I don't think a small difference in the test results is a big deal since the EPA and CR tests are different and different cars have different mpg sweet spots. That is, you would expect some cars to do better on the EPA test than on the CR test and vice-versa. A 10mpg difference (as with the Ford C-Max) is pretty alarming though. |
