In the example provided by the US DoE in its final rule, an electric car with an energy consumption of 265 Watt hour per mile in urban driving, and 220 Watt hour per mile in highway driving, results in a petroleum-equivalent fuel economy of 335.24 miles per gallon, based on a driving schedule factor of 55 percent urban, and 45 percent highway ...
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 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).
Hypermilers have broken records of fuel efficiency, for example, achieving 109 miles per gallon in a Prius. In non-hybrid vehicles these techniques are also beneficial, with fuel efficiencies of up to 59 mpg ‑US (4.0 L/100 km) in a Honda Accord or 30 mpg ‑US (7.8 L/100 km) in an Acura MDX .
The comparison showed little difference in performance when tested for fuel economy and acceleration. Overall fuel economy of the 2001 model was 40.6 miles per US gallon (5.79 L/100 km; 48.8 mpg ‑imp) while the 2002 Prius with high mileage delivered 40.4 miles per US gallon (5.82 L/100 km; 48.5 mpg ‑imp).
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 ...
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, [1] 2016, [2] 2017, [3] and 2023 [4] versus the model year 2016 vehicles that were rated the most efficient by the EPA with plug-in hybrid ...
The two-door first-generation Insight was estimated at 61 miles per US gallon (3.9 L/100 km; 73 mpg ‑imp) in city driving and 68 miles per US gallon (3.5 L/100 km; 82 mpg ‑imp) on the highway. [5] The Toyota Prius sold 300 units in 1997 and 19,500 in 2000, and cumulative worldwide Prius sales reached the one million mark in April 2008. [59]
