Average Fuel Efficiency of U.S. Passenger Cars and Light Trucks

KEY: CAFE = Corporate Average Fuel Economy; GVWR = gross vehicle weight rating; mpg = miles per gallon; U = data are not available.

(a) 1960-2006 data are for Passenger car and Other 2-axle, 4-tire vehicles, respectively. The data from 1960-2006 are not comparable to the data from 2007-15.

(b) From 1980 to 1994, Light duty vehicle, short wheel base (previously Passenger car) fuel efficiency includes motorcycles.

(c) Assumes 55% city and 45% highway-miles. The source calculated average miles per gallon for light-duty vehicles by taking the reciprocal of the sales-weighted...

Average Annual PMT, VMT Person Trips and Trip Length by Trip Purpose

KEY: PMT - Person Miles of Travel; VMT - Vehicle Miles of Travel.

U.S. Vehicle-Kilometers

KEY: N = data do not exist; R = revised; U = data are not available.

^a All operations other than those operating under 14 CFR 121 and 14 CFR 135. Data for 1996 are estimated using new information on nonrespondents and are not comparable to earlier years. Mileage in source is multiplied by 1.151 to convert to nautical-miles for 1985-1997.

^b Data from 2007 were calculated using a new methodology developed by FHWA. Data for these years are based on new categories and are not comparable to previous years. The new category Light...

Commodity Flow Survey Overview

The Commodity Flow Survey (CFS), a component of the Economic Census, is conducted every five years by the U.S. Census Bureau in partnership with the U.S. Department of Transportation’s Bureau of Transportation Statistics. The 2017 CFS is the sixth survey in the program that began in 1993. The CFS is a shipper survey of approximately 100,000 establishments from the industries of mining, manufacturing, wholesale trade, auxiliaries (i.e. warehouses and distribution centers), and select retail and service trade industries that ship commodities.

Energy Intensity of Light Duty Vehicles and Motorcycles (metric)

KEY: Btu = British thermal unit; N = data do not exist; U = data are not available.

^aMotorcycle is included in Light duty vehicle, short wheel base (previously Passenger car) in 1960 and 1965.

^b Energy Intensity (Btu/passenger-kilometer) is calculated by converting the fuel consumption in gallons to the energy equivalent Btu units and dividing by the passenger-kilometers. The heat equivalent factor used for Btu conversion is 125,000 Btus/gallon.
