Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Second, they estimated fuel savings using the FHWA data on vehicle miles, fuel use and miles per gallon (mpg).

DOE: Small SUVs halve lifetime GHG emissions as EVs vs. gas

Baua Electric

A small electric SUV with 300 miles of range produces 52% fewer life-cycle greenhouse gas emissions than a comparable gasoline vehicle, according to the U.S. The Union of Concerned Scientists (UCS) in 2020 found that 94% of Americans already lived in a place where, based on the local grid, electric cars were cleaner than 50-mpg gasoline cars.

EPA trends report sees record levels of average new vehicle fuel economy and CO2 emissions for MY 2012; role of new gasoline vehicle technologies

Green Car Congress

EPA projects advanced transmissions (6+ speeds and CVTs), gasoline direct injection (GDI) systems, and turbocharged engines will be installed on at least 15% of all MY 2013 vehicles. The majority of the emissions and fuel savings from current vehicles, EPA noted, is due to new gasoline vehicle technologies. mpg, or 22%.

EPA’s annual automotive trends report shows slight increase in fuel economy from MY2017 to MY2018

Green Car Congress

In model year 2018, the average estimated real-world CO2 emission rate for all new vehicles fell by 4 grams per mile (g/mi) to 353 g/mi, the lowest level measured since 1975, when EPA data collection began. Tesla improved fuel economy (as measured in miles per gallon of gasoline equivalent, or mpge).
