The rating for all-electric mode (left) is expressed in miles per gallon gasoline equivalent (mpg). Miles per gallon gasoline equivalent ( MPGe or MPGge) is a measure of the average distance traveled per unit of energy consumed. MPGe is used by the United States Environmental Protection Agency (EPA) to compare energy consumption of alternative ...
State Taxes. The United States federal excise tax on gasoline is 18.4 cents per gallon and 24.4 cents per gallon for diesel fuel. [ 1][ 2] Proceeds from the tax partly support the Highway Trust Fund. The federal tax was last raised on October 1, 1993, and is not indexed to inflation, which increased 111% from Oct. 1993 until Dec. 2023.
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). This measure is popular in the US and the UK (mpg ...
June 7, 2024 at 5:16 PM. WASHINGTON (AP) — New vehicles sold in the U.S. will have to average about 38 miles per gallon of gasoline in 2031 in real-world driving, up from about 29 mpg this year ...
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 overall fuel economy of cars in the United States increased from about 15 miles per US gallon (16 L/100 km; 18 mpg ‑imp) in 1979 to 18 mpg ‑US (13 L/100 km; 22 mpg ‑imp) by 1985 and 20 mpg ‑US (12 L/100 km; 24 mpg ‑imp) by 1990. [36] This was one factor leading to the subsequent 1980s oil glut.
Tight refining supply has kept the gap wide between wholesale gasoline futures and retail prices, currently at about $1.25 a gallon, far exceeding the average of 88 cents over the past five years.
v. t. e. Fuel efficiency (or fuel economy) is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier ( fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is ...
