The Vehicle Technologies Office (VTO) supports testing and data collection on a wide range of advanced and alternative fuel vehicles and technologies through the Advanced Vehicle Testing Activity (AVTA) .  The following table has downloadable performance, reliability, and driver behavior data for selected models of  all-electric vehicles (electric cars or AEVs), compressed natural gas vehicles (CNG), diesel vehicles, hybrid-electric vehicles (HEV), neighborhood-electric vehicles (NEV), plug-in hybrid electric vehicles (PHEV), and stop-start vehicles.   Working with government, commercial, utility, and other industry fleets, the AVTA conducts both laboratory and on-the-road testing. The full dataset for all report data is available as a spreadsheet on the Idaho National Laboratory's Advanced Vehicle Testing Activity page.
