Toyota is using a traveling exhibit to market the Prius beyond the coasts, The Wall Street journal reports.

A 53-foot trailer filled with exhibits on energy consumption and fossil fuels is making 150 stops at places where pickups, SUVs and cars sporting Detroit brands are popular. The “Highway to the Future” tour, which launched in January, is hitting places like Des Moines, Iowa; Livingston, Mont., and Chattanooga, Tenn.

There are signs that Toyota’s road show may be working. U.S. sales of new hybrid cars were up 49 percent in the first seven months of this year.

Hybrid sales were up 57 percent in the Midwest, 52 percent in the West, 49 percent in the Northeast and 42 percent in the South.
