Any easily attainable MPG gains will already have been realized and done by the factory ... it's what they sell cars by to many people ... over 40 would be a marketing coup. If they could have eked out 1 MPG better than the Elantras they would have .... they certainly would have done it if it could have been done as easily as with an air filter and tuning. I agree with another poster who indicated more aero underpinnings ... THEY WORK. So do skinny tires and full moon type hubcaps ... but is anybody REALLY going to do those things ? The easiest thing to do would be to slow down a little. And I'm not lecturing or parenting ... I could care less how fast somebody drives or how much they spend on gas. The biggest factor mentioned that causes the OP to get poor highway fuel mileage is SPEED ... get a free 8 MPG just by slowing down a little .... don't believe me ???? Try it for a tank.
To the poster supposedly getting 38+ MPG at close to 80 MPH. I don't buy it
.... the display may have said 38, but I'm betting calculations won't show that number.
Regarding your second point ... totally agreed. People will spend thousands more on a car that gets 2 MPG better on the highway ... not realizing it will take them 17 years to offset the extra cost.
