This is nothing special but just to show that there is potential in everycar, it's jsut a matter of the driver.
Candidate: 2002 Subaru WRX, all-wheel drive, 2.0 turbo engine, 227 HP.
Gas mileage mod: tires inflated to 37 psi.
Experiment: Drive back from my parent's home following an alternate route with a 90 KM/H speed limit. Weather is nice, 15-18 celcius.
This road is pretty much empty and just straighaways, it was real easy doing 90 km/h everywhere, pretty much 95% of the drive was at that speed, the engine runs at 2250 RPM.
results:
35.5 MPG, that's 7.5 over the 2002
27 mpg EPA highway rating.
That's all, I just wanted to express my joy that a car that does 0-60 in 5.7 seconds can do 35.5 MPG on the highway
PS: It's all in my gaslog.
