Fuel+efficiency

Fuel Efficiency
Only about 15% of the energy from the fuel you put in your tank gets used to move your car down the road or run useful accessories, such as air conditioning. The rest of the energy is lost to engine and driveline inefficiencies and idling. Therefore, the potential to improve fuel efficiency with advanced technologies is enormous.

There are other alternative fuels, these are some examples:

 * [[image:http://www.fueleconomy.gov/feg/images/biodiesel_logo.gif width="100" height="28" caption="Biodiesel Logo" link="http://www.fueleconomy.gov/feg/biodiesel.shtml"]] || [|Biodiesel] is derived from vegetable oils and animal fats. It usually produces less air pollutants than petroleum-based diesel. ||

Fuel cell vehicles powered by pure hydrogen emit no harmful air pollutants. ||

 Energy efficient technologies are available now! Many of the vehicles currently on display in dealer showrooms boast new performance-enhancing, fuel-saving technologies that can save you money. Efficiency Increase || [|Variable Valve Timing & Lift] improve engine efficiency by optimizing the flow of fuel & air into the engine for various engine speeds. || **5%** || [|Cylinder Deactivation] saves fuel by deactivating cylinders when they are not needed. || **7.5%** || [|Turbochargers & Superchargers] increase engine power, allowing manufacturers to downsize engines without sacrificing performance or to increase performance without lowering fuel economy. || **7.5%** || [|Integrated Starter/Generator (ISG) Systems] automatically turn the engine on/off when the vehicle is stopped to reduce fuel consumed during idling. || **8%** || [|Direct Fuel Injection] [|(w/ turbocharging or supercharging)] delivers higher performance with lower fuel consumption. || **11-13%** || have an infinite number of "gears", providing seamless acceleration and improved fuel economy. || **6%** || combine the efficiency of manual transmissions with the convenience of automatics (gears shift automatically). || **7%** ||
