The Toyota Tacoma is a pickup truck manufactured by the Japanese automobile manufacturer Toyota since 1995. The first-generation Tacoma, model years 1995 through 2004, was classified as a compact pickup. The second generation, model years 2005 through 2015, as well as the third generation, in production since 2015, are classified as mid-sized pickups. The Tacoma was Motor Trend‘s Truck of the Year for 2005. As of 2015, the Toyota Tacoma is sold in the United States, Canada, Mexico, Costa Rica, Bolivia, Bermuda, and the French territory of New Caledonia. The name “Tacoma” was derived from the Coast Salish peoples’ name for Mount Rainier in Washington.
