FINALLY.
Now we can hopefully get realistic mileage numbers. Here is a link to the site that compares old and new: http://www.fueleconomy.gov/feg/calculatorSelectYear.jsp According to that site the old 2002 WRX numbers were: 20/27 (with a combined 23). The new numbers are: 18/25 (combined 21) That is a hell of a drop in actual numbers.... and they do seem fairly accurate - I average between 24-27 mpg on mostly hw driving. |

They reflect cruising speeds on the highway of 70-75 more accurately. The old ratings were more realistic for 60 mph cruising speeds, which is pretty rare on open highway.

I thought the WRX's highway mileage would be affected more than it was, with that screaming 5th gear ratio. Oh, and how does the sedan get 21 combined, and my wagon gets 20 combined, but we're both 18/25?

I still don't understand how a dynamometer test (per their description of the test procedures) can account for weight / aeryodynamics differences in vehicles. |

Unless you drive like a grandma, my BS Flag has to come out. I drive almost exclusively HW on my 100 mile (round trip) commute, and I have never gotten above 28. Ever. Let alone "consistantly" getting above that number. How fast do you drive? And more importantly, how do you calculate your mileage? |

I too get 27mpg on the highway, either at 60mph or 80mph. But on my daily commute (short distances, city and highway) I only get 22-24mpg. But 18 seems low, even when I go on the Dragon (floored all day) I still get 20mpg.

Our 2.5i legacy gets 32-33 highway. Thats going about 70-75. Hardly ever do I see mpg drop lower then 27-28.

I seriously have my doubts that some people even know how to calculate their personal MPG figures.

Energy to move it is also easily calculatable and can be simulated by the dyno. |

have you ever read how they do the epa tests? its crazy unrealistic,,
From frequently asked questions about the EPA fuel economy: www.fueleconomy.gov/feg/info.shtml (http://www.fueleconomy.gov/feg/info.shtml) The test used to determine the city fuel economy estimate simulates an 11-mile, stop-and-go trip with an average speed of 20 mph. The trip takes 31 minutes and has 23 stops. About 18% of the time is spent idling, as in waiting at traffic lights or in rush hour traffic. The engine is initially started after being parked overnight. The test used to determine highway driving simulates a 10-mile trip and averages 48 mph. The maximum speed is 60 mph. The test is run with the engine warmed up and has little idling time and no stops. After driving the FEH for several months, it is hard for me to imagine how the EPA got higher MPG for city test over the highway test, especially if it was a new FEH. - City test is with cold engine and average speed is low, a case where I get worse MPG. - The highway test has warmed-up engine and averages 48MPH, which seems to be in FEH “sweet” spot for getting best fuel economy (and there is no wind drag in EPA test). Even when considering the EPA city estimate is lowered by 10% and the highway estimate by 22% from the laboratory test results, it still does not make sense. Reading posts from others at several FEH group sites, it appears almost all of us get better fuel economy on the highway than we do in city driving. There are of course exceptions of those who drive long stretches at 35-45MPH, but that is closer to the EPA highway test than it is to the city test. |

My computer reads around 31mpg on my 15 mile, 55mph commute to work. I'm only on my 2nd tank, so I haven't been able to calculate my mileage yet. (First tank was me hotrodding everywhere and the needle read slightly below full when I picked up the car.) Driving to the Y and grocery store that is 2 miles away is killing my mileage though.
I'm convinced I could easily get 32mpg by going 65 or 70mph on the interstate. ~~Quentin |

I calculated by just dividing miles driven by the amount I had to put in to fill the tank. I know it isn't the most accurate thing in the world, but I've driven several cars with mpg computers and have never had a problem beating the current epa ratings by at least 1-2mpg. |

You can just imagine the amount of error if they were to do that. "Sorry Subaru, Toyota and Pontiac we happened to test all your cars with a 10 knot headwind. Your EPA figures are going to suck this year. Meanwhile the Big 3 had their trucks tested with a 15knot tailwind. 25mpg trucks all around!" |

Glad to see it. While we have had trips where we get 52MPG in the Prius, in-town we've never even come close to getting 60MPG over a whole tank. These revised numbers definitely are more realistic and seem to be relatively inline with the adjustment occurring with non-hybrids like the Civic.

While the Prius and Civic hybrid are both hit the hardest with the new testing methods, it looks like all vehicles are taking a ~10% hit in freeway economy.
I'm still trying to figure out how the EPA got 60mpg with the Prius in a 30 min city run after a cold start. The Prius hardly turns off the engine until the coolant is warmed up, and that takes about 5 minutes. My drives typically had the Prius getting about 25mpg until it warmed up. The rest of the drive must really lend itself to the "pulse & glide" technique that hypermilers do when shooting for 100+mpg. Daily driving (22mi commute mostly freeway) I get 25mpg consistently in my wagon. Long trips get me 26-27mpg easily and I can get that mileage daily if I can keep my foot out of it. Best ever was 31mpg driving 55-60mph for most of it. |
