The Transportation Technologies Office (TTO) works with the National Laboratories and industry partners to collect and report data on vehicle performance, research projects, and the transportation sector broadly.
Transportation Sector Data
TTO publishes the Transportation Energy Data Book annually (both in PDF form and with downloadable Excel files) with Oak Ridge National Laboratory. The Data Book compiles information on petroleum consumption, vehicle use, transportation technologies, household vehicle characteristics, and fleet characteristics.

TTO also publishes the Fact of the Week, a fact with an accompanying graph or chart, to draw attention to particularly useful statistics.
TTO’s FuelEconomy.gov and the Alternative Fuels Data Center host graphs, maps, and downloadable data sets on vehicle fuel economy, alternative fuel use, and alternative fuel vehicles and stations.
Vehicle Performance Data
TTO supports the Advanced Vehicle Testing Activity, which collects on-road and in-laboratory data on advanced and alternative fuel vehicles and infrastructure. These results provide benchmark data that researchers can use to develop technology models and guide future research and development. Over the years, the program has tested a variety of technologies including hybrid electric, plug-in electric, neighborhood electric, start-stop hybrid, natural gas, clean diesel, and hydrogen internal combustion engine vehicles as well as electric vehicle supply equipment and batteries.
