According to the Federal Highway Administration, the average fueleconomy for all lightvehicles on the road today is 22.3 Since taxes are charged on a per-gallon basis, someone with a more efficient vehicle will pay less in taxes over the course of a year. Based on a vehicle with an average fueleconomy of 22.3
The gap between official and real-world fuel-economy figures in Europe has risen to about 38%, according to a new report published by the International Council on Clean Transportation (ICCT).

The US Environmental Protection Agency (EPA) released its annual Automotive Trends Report , which shows that model year (MY) 2021 vehiclefueleconomy 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 vehiclefueleconomy was 25.1 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. 0 g/mi—and highest fueleconomy, at 113.7
Fleet-wide fueleconomy for vehicles sold in the U.S. The real-world fueleconomy of light-duty vehicles sold in the U.S. has stumbled, according to the EPA's recently released 2022 Automotive Trends Report. The report points to increased SUV sales as one reason for the stagnation of efficiency.
To make driving less energy intensive than flying, the fueleconomy of the entire US fleet of light-duty vehicles would have to improve from the current 21.5 l/100 km) at the current vehicle load, or vehicle load would have to increase from the current 1.38 l/100 km) to at least 33.8 persons to at least 2.3
Vehiclefueleconomy improvements have slowed globally, according to the latest report from the Global FuelEconomy Initiative (GFEI): FuelEconomy In Major Car Markets: Technology And Policy Drivers 2005-2017. Overall, global fueleconomy has improved by an average of 1.7% L ge /100 km.
The action finalizes parts of the SAFE Vehicles Rule that was first proposed on 2 August 2018. This action is based on the premise that federal law preempts state and local tailpipe greenhouse gas (GHG) emissions standards as well as zero emission vehicle (ZEV) mandates. Earlier post.)
The turnover of household vehicles has slowed since 2009, based on US Department of Transportation surveys of household vehicle travel, the US Energy Information Administration (EIA) reported. The slowing of vehicle turnover has implications for transportation fuel consumption, because newer vehicles tend to have better fueleconomies.

NHTSA is also setting forth proposed augural standards for MY 2032 passenger cars and light trucks, that would increase at 2% and 4% year over year, respectively, as compared to the prior year’s standards. The proposal would also drive fuel efficiency improvements for heavy-duty pickup trucks and work vans.
increase in vehicle miles traveled (VMT) from 2020 to 2021 due to the gradual recovery from the COVID-19 pandemic, which limited travel in 2020. Fueleconomy of light-duty vehicles is another important factor. Fueleconomy of light-duty vehicles is another important factor.
Motor gasoline meets on-road passenger light-duty vehicle (LDV) travel demand, while diesel consumption meets our assumed increases in medium- and heavy-duty freight truck travel. Onsite electricity generation, primarily from solar photovoltaics (PV), grows faster than purchased grid electricity for buildings through 2050.
The number of vehicle miles traveled (VMT) by light-duty vehicles (i.e., passenger cars and light-duty trucks) increased by 48% from 1990 to 2019; VMT by medium- and heavy-duty trucks increased 109% over the same period.
