Fuel is part of the total cost of vehicle ownership, so fuel conservation should be an important factor when choosing a new car. Consider whether the car, truck or sport utility vehicle under consideration is bigger and heavier than necessary. Compare the Environmental Protection Agency fuel economy ratings on the vehicles you're considering. Other options to consider include:

• Four-wheel-drive vehicles generally use more gasoline than other vehicles, especially if the four-wheel-drive system is engaged during routine driving.
  
  
• Vehicles with automatic transmissions may use more gasoline than those equipped with manual transmissions.
  
  
• Smaller engines usually equate to better gas mileage.
  
  
• Vehicle engines that require premium fuel, as stated in the owner's manual, will cost more to operate in the long run.
  
  
• Some trucks, vans and SUVs come in several sizes and configurations. Models with a shorter bed, abbreviated cargo area or smaller cab are lighter and generally consume less fuel.
  
  
• Light exterior and interior colors and tinted windows can reduce heat buildup, which saves on air conditioning.
  
  
• Cruise control may be a fuel-saving option if you drive a lot on open roads. Maintaining a steady speed conserves fuel.

When shopping for a new or pre-owned vehicle, check AAA's annual New Car and Truck Buying Guide and Your Driving Costs publications, both of which are available from your local AAA office. Also, visit the automotive area of AAA's Web site—aaa.com—for helpful information and detailed vehicle comparisons. Many clubs also offer auto-buying services, which can save you money, regardless of what vehicle you choose.
