This car is driven at 55 MPH most of the time since February 2011 (65 MPH before that).
For a small, light car like this the single most important factor affecting gas mileage is wind resistance. Driving slower (thus reducing wind resistance) is the single most effective way to increase gas mileage. Basically it is a trade-off between time and money. The same principle applies to larger vehicles, but the speeds at which wind resistance is a significant factor will vary.
Other Gas Mileage Tips:
- Coasting in neutral on down-hill stretches improves mileage considerably.
- Keeping tires at maximum air pressure improves mileage considerably.
- Techniques for improving gas mileage only work if they are habitual.
- Gas mileage tends to be better with warmer weather and poorer with colder weather.
- Weather factors (especially wind) should be taken into consideration when evaluating new driving techniques.
- Less weight in the vehicle improves gas mileage, particularly when the road is not flat and level.
- Slower starts (in higher gears if possible) and costing as much as possible before stops improves gas mileage.
