Interior Volume Index-The interior volume index is listed for each body style: 2door (2-DR), 4d00r (4-DR), and hatchback (HTBK). The Interior Volume lndex is one way of estimating the space in a car. It is based on four measurements-head room, hip room, leg room, and shoulder room-for the front and rear seats, as well as trunk capacity. The lnterior Volume lndex is given as two numbers (in cubic feet). The first is an estimate of the size of the passenger compartment; the second, the size of the trunk or, in station wagons and hatchbacks, the cargo space behind the second seat.

Factors That Affect Fuel Economy The fuel economy numbers in this Guide are based on carefully controlled tests performed on well- maintained vehicles. No standardized test of this type can ever represent each person's indiidual driving. What you actually get is likely to be lower or higher.

In buying a new car, you should recognize that the EPA estimates do not predict the mileage you will obtain. Instead, these estimates provide a way to compare the relative fuel economy performance of different new models when they are driven under the same test conditions.

Page 5: Gas Mileage Guide - Energy.govFor a 20-mpg vehicle, this is about 1.5 mpg. Wind Wind can increase or decrease fuel economy. Examples for a car that normally gets 20 rnpg are: 18 mph

Such things as trip length, weather, condition of the car, number of accessories, and individual driving habits have a significant effect on mileage. The conditions under which you drive your car in many

@ cases will not match the EPA test conditions due to the tremendous variety of in-use conditions. But even where your driving conditions are very similar to the test, technical factors and production variability would cause your mileage to be higher or lower than that measured on a standard test. The

a following paragraphs explain how some of these factors affect fuel economy.

Temperature Summer temperatures (over 70" F.) are better for fuel economy than winter temperatures. At 20' F., for example, there can be an approximate 8- percent fuel economy loss compared to the estimated rnpg number in this Guide. For a 20-mpg vehicle, this is about 1.5 mpg.

Wind Wind can increase or decrease fuel economy. Examples for a car that normally gets 20 rnpg are:

18 mph tailwind+about 12-percent gain in fuel economy (2.4 rnpg).

18 mph crosswinckabout 1 -percent loss in fuel economy (0.2 rnpg).

18 mph headwind+about 10-percent loss in fuel economy (2 mpg).

Precipitation Rain or snow, and the wet roads that result, can cause an approximate 10-percent loss in fuel economy (2 rnpg for a 20-mpg vehicle).

Road Condition Rough or loose road surfaces (such as sand or gravel) can also cause a fuel economy loss ranging between 10 and 30 percent (or 2 to 6 rnpg for a 20- rnpg vehicle). Cars use more fuel on hilly roads than flat roads. The fuel saved in going downhill does not equal. the extra fuel used going uphill.

Mountain driving causes an even greater fuel economy ~ ~ l t y .

How You Drive An engine that is already warmed up (such as one that was used in the last 4 hours) requires less fuel to reach its mod efficient operating condition than a "cold" engine (such as one in a car parked overnight).

Trip length also affects fuel economy. Shorter trips (under 5 miles) do not aHuw the engine to reach its best operating condition; longer trips allow the peak operating temperature and engine condition to be obtained. Thus, by combining numerous short trips into a single, longer trip you can save fuel both by reducing the total miles driven and by taking advantage of your vehicle's warmed-up condition.

Smooth, even driving improves fuel economy performance; therefore, try to avoid sudden stops and starts. By anticipating stop lights and intersections, you can slow down gradually. Also, avoid rapid accelerations. On the highway, you will improve your fuel economy by driving at or below the 55-mph speed limit.

Your Vehicle's Condition

The condition of your vehicle is important, too, for fuel economy reasons:

Maintain your vehicle according to the manufacturer's specifications. On the average, a tuned-up vehicle gets approximately 5 percent better fuel economy than one that has not been properly maintained. Keep the tires inflated to the proper pressure. Underinflated tires can cause a fuel economy loss.
