Funny how that happened.
I'll deduct from that you don't like the site because it confirms your higher speed driving is killing your MPG's. Don't kill the messenger.
Why are you comparing it to other manufactures cars? That isn't how the EPA numbers are derived, and the numbers on your sticker are accurate for your car!
So why is this discussion in the Warranty Complaint thread?
When I test drove a '12 Impreza I reset the readout on the freeway and it said I got over 35 mpg at 75 mph (two way average, flat road). I used that information in my decision to buy the car. Little did I know that information was ... incorrect.
It was a little below my old Corolla that was rated (2008 renorming) the same 36 mpg highway, but I figured I could live with it.
Same EPA, same tests, should be the same mpg. Your question of why am I comparing it to another manufacturer's car is puzzling. I am not sure why you don't get that 2 should equal 2 - or in this case 36 should equal 36. 36 does not equal 27.
Most cars are not actually tested by the EPA, the EPA just uses numbers submitted by the manufacturer. I would like to know if the Impreza was actually tested by the EPA. Is there an online list somewhere of what they have actually tested?
