Use the links below to learn more about fuel consumption and emissions, innovative fuel-saving technologies and the factors that affect your vehicle’s fuel efficiency. The information can help you make informed, energy-efficient decisions about the vehicle you buy and how you drive it.
Fuel consumption testing helps consumers make informed, energy-efficient purchase decisions by providing a reliable comparison of the relative fuel consumption performance of different vehicles.
Hybrid-electric vehicles combine a battery-powered electric motor with a conventional internal combustion engine. Hybrids cannot be charged using external electricity – they use the gasoline engine, regenerative braking and the energy produced from coasting to recharge their batteries.
Plug-in hybrid electric vehicles (PHEVs) are hybrids with high-capacity batteries that can be charged by plugging them in. When operating in electric-only mode, PHEVs produce no tailpipe emissions.
Battery-electric vehicles are propelled by an electric motor (or motors) that draw electricity from on-board rechargeable batteries. When the batteries run low, they must be plugged in to recharge. Electric vehicles produce no tailpipe emissions.
Manufacturers continue to improve transmission efficiency by using innovative technologies. Selecting a vehicle that has the most advanced transmission technology can help to reduce your fuel consumption and greenhouse gas emissions.
Manufacturers continue to improve engine fuel efficiency through technology improvements that include direct fuel injection, cylinder deactivation, variable valve timing and lift, turbocharging and idle stop-start.
