The Nissan Titan is a full-size pickup truck manufactured in the United States for the North American market by Nissan. It was named for the Titans of Greek mythology. First generation (A60; 2003) Development of the Titan began in September 1999, with design work under Diane Allen. Giovanny Arroba's TA60 exterior was chosen in late 2000, with a final production freeze in July 2001. The design language of the future truck was previewed by the 2001 Alpha T concept shown at the 2001 Detroit Auto Show, which had previously developed through November 2000. Production began on September 21, 2003 and sales on December 1, 2003. The Titan used Nissan's new full-size F-Alpha platform. This new platform was shared with the Nissan Armada and Infiniti QX56 SUVs, with all three manufactured in Canton, Mississippi, United States. The first generation Titan continued without a major redesign through 2015.
