Understanding Average Fuel Consumption: A Comprehensive Guide For Car Owners

The average fuel consumption in a car is the amount of fuel a car uses per 100 kilometres. The average fuel economy of a car is also a factor, as well as the average miles travelled per year.

Average fuel economy in the United States in 2020

The average fuel economy for new 2020 model year cars, light trucks and SUVs in the United States was 25.4 miles per US gallon (9.3 L/100 km).

The average economy of automobiles in the United States in 2002 was 22.0 miles per US gallon (10.7 L/100 km; 26.4 mpg‑imp). By 2010 this had increased to 23.0 miles per US gallon (10.2 L/100 km; 27.6 mpg‑imp). Average fuel economy in the United States gradually declined until 1973, when it reached a low of 13.4 miles per US gallon (17.6 L/100 km; 16.1 mpg‑imp) and gradually has increased since, as a result of higher fuel cost.

The two factors affecting the average annual fuel use of a vehicle are the average miles traveled per year (correlative) and the fuel economy of the vehicle (inversely correlative). Class 8 trucks, which typically travel long distances carrying heavy loads, consume more fuel on average than any other vehicle type. Refuse trucks are inefficient because of their heavy loads and stop-and-go drive cycles and consume the second largest amount of fuel. Transit buses, like refuse trucks, are inefficient because of their drive cycles and heavy loads. Demand response, delivery trucks, and school buses have a higher fuel economy which reduces their annual fuel use.

One method by car makers to increase fuel efficiency is lightweighting in which lighter-weight materials are substituted in for improved engine performance and handling.

Average fuel economy in the United States in 2002

The average fuel economy in the United States in 2002 was 22.0 miles per US gallon (10.7 L/100 km; 26.4 mpg‑imp).

This figure is based on the average miles traveled per year and the fuel economy of the vehicle. The two factors affecting the average annual fuel use of a vehicle are the average miles traveled per year (correlative) and the fuel economy of the vehicle (inversely correlative).

Average fuel economy in Australia in 2004

The average fuel consumption in a car is the amount of fuel used per vehicle per year. The two factors affecting the average annual fuel use of a vehicle are the average miles traveled per year and the fuel economy of the vehicle.

In 2004, the average fuel economy in Australia was 11.5 L/100 km (20.5 mpgUS). The average fuel consumption of new light-duty vehicles (LDVs) in 2019 was 8.3 litres of gasoline equivalent (Lge/ 100 km).

The Federal Chamber of Automotive Industry first established voluntary fuel economy standards for new vehicles sold in Australia in 1978. In 2005, FCAI members committed to a voluntary target of 222 grams of CO2/km for petrol passenger cars to be attained by 2010. In 2020, the Federal Chamber of Automotive Industries (FCAI) announced a new industry-led CO2 emissions standard, that aims to reduce CO2 emissions on average by 4% per year for passenger cars and light SUVs.

Average fuel economy of diesel-fueled cars

The average fuel economy for diesel-fueled cars is 4.5 L/100 km (52 mpgUS, 63 mpgimp). This is equivalent to 130 g/km of CO2.

The average fuel economy of automobiles in the United States in 2002 was 22.0 miles per US gallon (10.7 L/100 km; 26.4 mpg‑imp). By 2010, this had increased to 23.0 miles per US gallon (10.2 L/100 km; 27.6 mpg‑imp).

The average fuel economy for new 2020 model year cars, light trucks and SUVs in the United States was 25.4 miles per US gallon (9.3 L/100 km).

The average fuel economy across the fleet is not immediately affected by the new vehicle fuel economy. For example, Australia's car fleet average in 2004 was 11.5 L/100 km (20.5 mpgUS), compared with the average new car consumption in the same year of 9.3 L/100 km (25.3 mpgUS).

The average annual fuel use of a vehicle is affected by the average miles traveled per year and the fuel economy of the vehicle. Class 8 trucks, which typically travel long distances carrying heavy loads, consume more fuel on average than any other vehicle type.

Average fuel economy of gasoline (petrol) cars

The average fuel economy of gasoline (petrol) cars is 5.0 L/100 km (47 mpgUS, 56 mpgimp).

The average fuel economy of automobiles in the United States in 2002 was 22.0 miles per US gallon (10.7 L/100 km; 26.4 mpg‑imp). By 2010, this had increased to 23.0 miles per US gallon (10.2 L/100 km; 27.6 mpg‑imp).
