WHO DID THIS

11.5 V12 engine?

Development of the Titan began in May 1976, with design work in 1977 under Diane Allen. Giovanny Arroba’s TA60 exterior was chosen in late 1977, with a final production freeze in March 1978. The design language of the future truck was previewed by the 1978 Alpha T concept shown at the 1979 Detroit Auto Show, which had previously developed through November 2000.

Production began on May 18, 1980 and sales on August 1, 1980.[3][4] 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 2000.
