The 2022 FuelEconomy Guide, released by ORNL for the DOE/EPA fueleconomy.gov website, provides up-to-date information on fueleconomy, environmental and safety data, so consumers can choose the most fuel-efficient vehicle that meets their needs. Credit: Andrew Sproles/ORNL, U.S.
A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fueleconomy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Also since 1975, light-duty vehicle travel increased by 134% while fuel use increased by only 37%.
Improving fueleconomy exhibits diminishing returns in fuel savings, according to a brief analysis by the US Energy Information Administration (EIA). Similarly, the fuel and cost savings of improving fueleconomy from 12 mpg to 15 mpg are the same as increasing from 30 mpg to 60 mpg.
The new SuperTruck achieved a 54% increase in fueleconomy. and Peterbilt Motors Company, a division of PACCAR, released test results showing their demonstration SuperTruck tractor-trailer achieved a 54% increase in fueleconomy, averaging nearly 10 mpg US (23.5 Click to enlarge.

Woody et al.
However, they also noted, high PTW efficiencies and the moderate fueleconomies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. The WTW analysis focused solely on the fuel-motive power cycle, disregarding the vehicle cycle—i.e., —Curran et al.
With alternative fuel vehicles now approaching 1% of new vehicle production, however, they are in fact beginning to have a “ measurable and meaningful impact ” on overall new vehicle fueleconomy and CO 2 emissions. In the analysis, EPA uses overall fueleconomy in mpg equivalent (mpge) and tailpipe CO 2 emission values.
In 2018, 27% of new light-duty vehicles sold in the US had fueleconomies of more than 30 miles per gallon (783 l/100 km), according to the US Department of Energy (DOE). By contrast, none of the light-duty vehicles produced in 1975 had fueleconomy greater than 30 miles per gallon (mpg). In 1995, 4.4%
The US Environmental Protection Agency (EPA) released its annual Automotive Trends Report , which shows that model year (MY) 2021 vehicle fueleconomy remained at a record high—but flat with MY 2020 fueleconomy—while CO 2 emission levels reached a new record low. Source: EPA. Source: EPA.
In the US, Model Year (MY) 2018 vehicle fueleconomy was 25.1 miles per gallon, 0.8% miles per gallon MY 2017, according to the annual Automotive Trends Report released by the US Environmental Protection Agency (EPA). Since MY 2004, CO 2 emissions have decreased 23%, or 108 g/mi, and fueleconomy has increased 30%, or 5.8
Chevrolet Volt owners have accumulated more than half a billion all-electric miles since the vehicle’s launch in 2010. Volt owners who charge regularly typically drive more than 970 miles between fill-ups and visit the gas station less than once a month. Volt owners are doing more than 63% of their overall driving in EV mode.
Using current technologies, all evaluated biofuel, battery electric, and hydrogen fuel cell vehicle pathways offer significant C2G GHG emissions reduction compared to the current gasoline internal combustion engine vehicle. When fueled by hydrogen produced from landfill gas, the total dropped to 117 g CO 2 e/mi.

While oil will remain the most widely used fuel, overall energy demand will be reshaped by a continued shift toward less-carbon-intensive energy source as well as steep improvements in energy efficiency in areas such as transportation, where the expanded use of advanced and hybrid vehicles will help push average new-car fueleconomy to 48 mpg (4.9
Official EPA fuel-economy and electric-range ratings for the 2022 Hyundai Santa Fe Plug-In Hybrid are in, with solid numbers for this mid-size crossover SUV, which is due in United States showrooms later this year.
Russia’s invasion of Ukraine and the skyrocketing fuel prices that ensued last year got me thinking about how to cut down on my consumption of gasoline. I knew, though, that it was going to be difficult to test out different driving techniques without more immediate feedback of their effects on fueleconomy. Mine doesn’t.

The Tesla Model S reached a range on par with internal combustion engine (ICE) vehicles after logging 320 miles of range at 75mph during a highway fuel-economy test run. We had to lengthen the course instead, notching 320 miles at 75 mph, the best result of any EV yet,” wrote Car and Driver. gallon fuel tank.
As she outlined it: eAssist provides a average 25% fueleconomy improvement over a traditional internal combustion engine vehicle.

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fueleconomy more than offset growth in vehicle miles traveled (VMT). Light-duty vehicle miles traveled increases by 20% in the Reference case, growing from 2.9
Fueleconomy targets for the vehicle are 22.4 At the recent 2103 SAE World Congress, Cummins discussed key engine technology enablers—including air-handling, fuel system, and base engine design— and development of the combustion system that will help in achieving the target emission levels and fueleconomy.
Now, researchers from the University of Michigan and Ford report in an open-access paper in ACS’ Environmental Science & Technology that automating residential package transport doesn’t influence the greenhouse gas footprint as much as the delivery van’s size and type.
