  2. Corporate average fuel economy - Wikipedia

    en.wikipedia.org/wiki/Corporate_average_fuel_economy

    The program covered model year 2012 to model year 2016 and ultimately required an average fuel economy standard of 35.5 miles per US gallon (6.63 L/100 km; 42.6 mpg ‑imp) in 2016 (of 39 miles per gallon for cars and 30 mpg for trucks), a jump from the 2009 average for all vehicles of 25 miles per gallon.

  3. Fuel efficiency - Wikipedia

    en.wikipedia.org/wiki/Fuel_efficiency

    v. t. e. Fuel efficiency (or fuel economy) is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is ...

  4. Energy efficiency in transport - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency_in_transport

    The energy efficiency in transport is the useful travelled distance, of passengers, goods or any type of load; divided by the total energy put into the transport propulsion means. The energy input might be rendered in several different types depending on the type of propulsion, and normally such energy is presented in liquid fuels, electrical ...

  5. Miles per gallon gasoline equivalent - Wikipedia

    en.wikipedia.org/wiki/Miles_per_gallon_gasoline...

    The following table compares EPA's estimated out-of-pocket fuel costs and fuel economy ratings of serial production plug-in hybrid electric vehicles rated by EPA as of January 2017 expressed in miles per gallon gasoline equivalent (mpg-e), [6] [86] versus the most fuel efficient gasoline-electric hybrid car, the 2016 Toyota Prius Eco (fourth ...

  6. Thrust-specific fuel consumption - Wikipedia

    en.wikipedia.org/wiki/Thrust-specific_fuel...

    Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific. This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit ...

  7. Fuel economy in automobiles - Wikipedia

    en.wikipedia.org/wiki/Fuel_economy_in_automobiles

    Fuel consumption monitor from a 2006 Honda Airwave.The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.

  8. Efficient energy use - Wikipedia

    en.wikipedia.org/wiki/Efficient_energy_use

    Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, insulating a building allows it to use less heating and cooling energy while still ...

  9. Energy-efficient driving - Wikipedia

    en.wikipedia.org/wiki/Energy-efficient_driving

    Energy-efficient driving techniques are used by drivers who wish to reduce their fuel consumption, and thus maximize fuel efficiency. Many drivers have the potential to improve their fuel efficiency significantly. [1] Simple things such as keeping tires properly inflated, having a vehicle well-maintained and avoiding idling can dramatically ...
