For Monroney fuel economy the equation is. where. is expressed as miles per gallon gasoline equivalent (as shown in the Monroney label) E G = {\displaystyle E_ {G}=} energy content per gallon of gasoline = 115,000 Btu /gallon, as set by U.S. DoE and reported by the Alternative Fuel Data Center.
The fuel consumption is an equivalent measure for cars sold outside the United States, typically measured in litres per 100 km traveled; in general, the fuel consumption and miles per gallon would be reciprocals with appropriate conversion factors, but because different countries use different driving cycles to measure fuel consumption, fuel ...
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 often ...
The following table compares official EPA ratings for fuel economy (in miles per gallon gasoline equivalent, mpg-e or MPGe, for plug-in electric vehicles) for series production all-electric passenger vehicles rated by the EPA for model years 2015, 2016, 2017, and 2023 versus the model year 2016 vehicles that were rated the most efficient by the EPA with plug-in hybrid drivetrains (Chevrolet ...
Automobile fuel efficiency is most commonly expressed in terms of the volume of fuel consumed per one hundred kilometres (l/100 km), but in some countries (including the United States, the United Kingdom and India) it is more commonly expressed in terms of the distance per volume fuel consumed (km/L or miles per gallon). This is complicated by ...
Fuel efficiency is on the mind of a lot of car shoppers these days, and automakers have responded with more vehicles that get 40 miles per gallon -- or even more. Today's super-efficient cars are ...
Fuel economy is the distance travelled per unit volume of fuel used; for example, kilometres per litre (km/L) or miles per gallon (MPG), where 1 MPG (imperial) ≈ 0.354006 km/L. The higher the value, the more economic a vehicle is (the more distance it can travel with a certain volume of fuel). This measure is popular in the US and the UK (mpg ...
Fifty-four-point-five miles per gallon. On average. By 2025. It almost sounds a little crazy, but that's what the man said. And the man in question being no less than President Obama himself, this ...
