This chart shows trends in fleet composition by weight categories in U.S. light-duty vehicles from 1975 to 2011. The relative popularity of light trucks (including trucks, SUVs, and vans) increased fairly steadily from the early 1980s through the mid-2000s. Following the oil price spikes of 1979 and 2008, there were notable decreases in the percentage of light trucks. See also Efficiency and Power of U.S. Light-Duty Vehicles Over Time.
