Fuel Mileage for the 2006 Aston Martin DB9 Coupe


The 2006 Aston Martin DB9 Coupe minicompact car, with automatic six speed select shift transmission, a 5.9 cubic liter, 12 cylinder motor (premium gasoline, subject to gas guzzler tax) is estimated to get 12 miles per gallon (5.1 kilometers per liter) in the city and 19 miles per gallon (8.1 kilometers per liter) out on the highway. Its estimated annual fuel cost is $2,401.



This assumes that you travel 15,000 miles (24,140 kilometers) per year, 55 percent under city driving conditions and 45 percent under highway conditions, and that fuel costs $2.20 per gallon for regular unleaded gasoline and $2.40 per gallon for premium.

Keep in mind that each vehicle reaches its best fuel economy at different speeds, or ranges of speed. Usually, gas mileage decreases quickly when you drive over 60 miles per hour (96 kilometers per hour). Although each car is different, as a general rule, for every 5 miles per hour you drive over 60 miles per hour, you pay an additional 21 cents per gallon of gasoline.


Removing extra weight also helps increase fuel economy. Here the rule is that you pay about 3 to 6 cents per gallon for each 100 pounds of weight you have in the car. Again each automobile and situation is different.

Finally, idling less, and using the cruise control when you drive improves fuel mileage.
