For each model. there aredesignations of the engine size and thetype of transmission ("A" for automat c:"M"for manual). The type of each vehicle's fuelsystem is indicated either by "FI" for fuelinjection or by the number of barrels in thecarburetor. The interior volume index columnlists two numbers (in cubic feet). The first is anestimate of the size of the passengercompartment: the second, the size of thetrunk or. in station wagons and hatchbacks,the cargo space behind the second seat.Three Fuel Economy EstimatesCity fuel economy reflects trips for local errands,driving to work, and general stop-and-go driving inurban and suburban areas.Highway fuel economy reflects long-distancedriving on non-urban roads and on interstatehighways at a speed averaging about 50 MPHwith no stops.3

fuel economy is a weighted average ofhighway estimates based on Federalstudies of average US.alue (which assumesnd half highway driving) ISwhat the average driver can expect in overallummer driving on level roads after the car haseen broken in.Fuel CostThis value is an estimate of what you would payfor fuel in 1 year if you drive 15,000 miles and pay65 cents per gallon for gasoline (or 55 cents pergallon for diesel fuel). Check the Fuel Costadditional information on yearly fuel costs aterent prices per galion.II you don't know which class a vehicle is in, turnto the index where manufacturers and car linesare listed alphabetically. Aiter each model name,the appropriate size class is given. By locatingthat size class and the manufacturer, you will beable to find the specific model. The index islocated on pages 28-32.Additional information is provided in this Guide on.o Factors that affect fuel economy (page 6).@ EPA fuel economy tests (page 8).All 1977 passenger .automobiles and light trucksare required to h w e gas mileage labels if theyhave gross vehicle weights of 6000 pounds orless. There are two types of labels. The one thatwill appear on most vehicles is the General Label.The fuel econcmy numbers on these labels arethe same as those that appear in this "GasMileage Guide" and are based on an average offuel economy test results for similar versions of agiven model.ich will be clearly markedve additional informationabout that vehicle's characteristics andnomy estimates that relate to aal vehicle within the model line.cause of this, the Specific Label in some casesI have fuel economy estimates that are differentfrom the General Label values in the "GasMileage Guide."Also, the estimates on a Specific Label may notfall into the range of fuel economy estimateslisted for its class. This is because a specificmodel may be more fuel efficient than the averagefor the model type-uel Costs, Iner 10,000 MilesExample: If you pay an average of 60 cents per gallonand your car gets 12 MPG, your fuel cost for 10,000miles of driving is 500. If you drive 20,000 miles ayear, your annual fuel cost will be twice this figure, or 1,000. If you own a car that gets 20 MPG, yourannual fuel cost for 10,000 miles at 60 cents pergallon is 300.

Mountaingreater fuel economy penalty.IAn engine that is already warmed up (such as onethat was used in the last 4 hours) requires lessfuel to reach its most efficient operating conditionthan a "cold" engine (such as one in a car parkedovernight). Trip length also affects fuel economy.Shorter trips (under 5 miles) do not allow theengine to reach its best operating condition,whereas longer trips allow the peak operatingtemperature and engine condition to be obtained.This does not mean that you can save fuel byincreasing the length of your short trips. It doesmean that.by combining numerous short trips intoa single, longer trip you can save fuel by reducingthe total miles driven as well as taking advantageof your vehicle's warmed-up condition.Smooth, even driving improves fuel economyperformance; therefore, try to avoid sudden stopsand starts. By anticipating stop lights andintersections, you can slow down gradually. Also,avoid rapid accelerations. On the highway, you willimprove your fuel economy by driving at or belowthe 55-MPH speed limit.Your Vehicle's ConditionThe condition of your vehicle is important, too, forfuel economy reasons:Maintain your vehicle according to themanufacturer's specifications. On the average,a tuned-up vehicle gets approximately 3 to 9percent better fuel economy than one that hasnot been properly maintained.Keep the tires inflated to the proper pressure.Underinflated tires can cause a fuel economyloss.For a more detailed technical discussion of thefactors that affect fuei economy, write for"Factors Affecting Fuel Economy"Public Information Center (PM-215)US.

\Fuelom tests conducted or approved bythe U.S. Environmental Protection Agency (EPA).These tests are performed on vehicles submittedy the auto industry to EPA to demonstrateompliance with the requirements of the Ciean Airct and the Energy Policy and Conservation Act.Each vehicle is tested under precisely controlledconditions by professional drivers in a laboratorydynamometer. The dynamometer is amachine that permits exact sirnulvehicle's operation under variousconditions. Temperature is controlled in thelaboratory in a range of 68" to 86 F. in order toprovide the same temperature conditions for allvehicles.*0ulates a 7.5-mile, stop-and-go tripwith a speed range of 0 to 56 MPH, and anaverage speed of 20 MPH. The trip takes 23minutes and has 18 stops. Eighteen percent ofthe trip is spent idling, such as would be expectedin the city at traffic lights or in rush-hour traffic.Two kinds of engine starts are used. One is a coldstart, which is similar to starting a car in themorning after it has been parked all night. Theother is a hot start, which is similar to starting avehicle after having parked it for a short timehile shopping. The information from this test isthen combined to represent the fuel economy ofthat vehicle during a realistic mixture of hot andcold starts during urban driving conditions.begins with the vehan average speed of about 50 MPH and lasts 13minutes. The speed during the test ranges from 0to 60 MPH. If your highway driving speedaverages faster han the test's average of 50expect to achieve poorer fueleconomy than the highway fuel economyestimate in this Guide-about 10 to 15 percentless for every 10 MPH above 50 MPH.*8GREMLINAVANT lAVANT!
