  2. 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.

  3. Thrust-specific fuel consumption - Wikipedia

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

    The fuel consumption per mile or per kilometre is a more appropriate comparison for aircraft that travel at very different speeds. [citation needed] There also exists power-specific fuel consumption, which equals the thrust-specific fuel consumption divided by speed. It can have units of pounds per hour per horsepower.

  4. Miles per gallon gasoline equivalent - Wikipedia

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

    Fuel consumption is the reciprocal of fuel economy, and measures the fuel used to drive a fixed distance (units of gal/100 miles or kWh/100 miles). [36] The unit of Gal/100 miles is accurately described as fuel consumption in some EPA brochures, but this unit appears in the fuel economy section of the Monroney label (which does not use the term ...

    Based on the Department of Energy’s fuel economy calculator, assuming you drive 15,000 miles a year, the Ford F-150 Lightning could save $16,630 on fuel costs over 10 years compared its gas ...

  6. Energy efficiency in transport - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency_in_transport

    The environmental calculator of the French environment and energy agency (ADEME) published in 2007 using data from 2005 [144] enables one to compare the different means of transport as regards the CO 2 emissions (in terms of carbon dioxide equivalent) as well as the consumption of primary energy.

  7. Energy-efficient driving - Wikipedia

    en.wikipedia.org/wiki/Energy-efficient_driving

    Simple model for energy vs vehicle speed. Air resistance is the main cause expended energy per distance when driving at high steady speeds. [11] At higher speeds, wind resistance plays an increasing role in reducing fuel economy in automobiles. At 60km/h, the global average speed, energy loss due to air drag in fossil fuel cars is approximately ...

  8. Consumption map - Wikipedia

    en.wikipedia.org/wiki/Consumption_map

    A consumption map or efficiency map [1] is a chart that displays the brake-specific fuel consumption of an internal combustion engine at a given rotational speed and mean effective pressure, in grams per kilowatt-hour (g/kWh). The map contains each possible condition combining rotational speed and mean effective pressure.

  9. Fuel economy in aircraft - Wikipedia

    en.wikipedia.org/wiki/Fuel_economy_in_aircraft

    By increasing efficiency, a lower cruise-speed augments the range and reduces the environmental impact of aviation.According to a research project completed in 2024 and focusing on short to medium range passenger aircraft, design for subsonic instead of transonic speed (about 15% less speed) with turboprop instead of turbofan propulsion would save 21% of fuel compared to an aircraft of ...
