Horsepower To get the maximum amount of choices, select as many ranges as possible. The lower the horsepower, the better gas mileage you will get. The greater the horsepower, the higher performance your car will have. Horsepower is a standard measurement used to determine how much effective power an engine produces. # Safety Features Safety equipment in the Find By Criteria feature includes a driver airbag, passenger airbag, side airbag, 1997 side-impact protection, anti-lock brake system, traction control, and child safety locks. If you select a safety feature, only vehicles that have this feature as standard or optional will appear in the Personal Find List. Otherwise the feature is not available. # Fuel Economy You can check either city or highway miles per gallon (MPG) (but not both at the same time) when using the Find By Criteria feature. The more MPG ranges you check, the greater your selection of cars. When selecting MPG ranges, select several close together to get vehicles that are competitors.
