That's what the digital readout says. WRONG. That readout is no way close. I filled up and my actual mileage was 24.2 MPG. I have checked this a few times and the digital readout is always a couple MPG higher than actual. I'm very disappointed in the mileage. Best I ever had on the highway is 33 MPH on digital readout but 31 in actual calculations. So I get 24 city/road and 31 road. That sucks! I'm going to go to the dealer where I bought the car and ask why. Not close to what it should get. Might sell it and find a car that gets good mileage.
You're not alone. The only thing is that mine shows the same difference in actual mpg vs. the display, but when you consider how far the odometer is off combined with what it will show when the tires are worn down, it's pretty close. Check it with a GPS. There have been several car magazine reviews, but not very many that actually checked the mpg. The ones that checked it found it came way short of claimed. Even Consumer Reports, in their comparison of real world mpg's of other cars, report that the Impreza was woefully bad in mpg. The cvt is bad - I don't know about the 5 speed since I don't have one, but I hear it's not too far off, and actually maybe better in real world mpg's.
