The MPGe metric was introduced in November 2010 by EPA in the Monroney sticker of the Nissan Leaf electric car and the Chevrolet Volt plug-in hybrid. The ratings are based on EPA's formula, in which 33.7 kWh (121 MJ) of electricity is equivalent to one (U.S.) gallon of gasoline, [ 8 ] and the energy consumption of each vehicle during EPA's five ...
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 ...
We explain EPA ratings, factors affecting range, how EVs performed in our testing, and why it's all complicated and different from the gas-powered-vehicle norm.
The ratings are based on EPA's formula, in which 33.7 kilowatt hours of electricity is equivalent to one gallon of gasoline (giving a heating value of 115,010 BTU/US gal), and the energy consumption of each vehicle during EPA's five standard drive cycle tests simulating varying driving conditions.
The metric is new to most, but it doesn't have to be as confusing as it sounds.
A 2020 Tesla Model Y Performance will go 315 miles on a full charge, according to final numbers posted to the EPA’s fuel economy site. Forbes spotted the posting first, and they match the ...
The mileage for dual-fuel vehicles, such as E85 capable models and plug-in hybrid electric vehicles, is computed as the average of its alternative fuel rating—divided by 0.15 (equal to multiplying by 6.666)—and its gasoline rating. Thus an E85-capable vehicle that gets 15 mpg on E-85 and 25 mpg on gasoline might logically be rated at 20 mpg.
Following an investigation and audit brought on by a number of consumer complaints, the U.S. Environmental Protection Agency (EPA) has changed the estimated fuel economy ratings for the majority ...
