My name is Stacey. I just got a couple of weeks ago a Toyota Yaris after losing my other vehicle(Ford Taurus) to a deer. I love the little car and have been pleased with the mpg I have gotten already out of it but I have heard of people getting more and I want to try it. My best tank so far has been 37mpg. My short term goal is 40mpg. The biggest change in my driving habits has been my reduction in speed. about 90% of my driving is on the interstate. I drive 50mile to work each day. My car is a 2007 Toyota Yaris with a manual transmission. The only addition is my new ScangaugeII. I just got it yesterday and am looking forward to using it.
If most of your driving is on the interstate, then modding to reduce aerodynamic drag is the way to go and will allow you to get good gas mileage without having to slow down as much as when driving a "normal" Cd car. Also if you aero mod the front of your car with a rounded front nose, you can send the next deer you hit up and over the top of your car. The last deer I hit (at 45mph) was thrown straight up and over the top of my car by the cowcatcher-like shape of the front of my car. Total cost of the damage from the collision, $35 for a cracked headlight cover.
