Despite lackluster sales, Nissan Motor Corp. is giving the Titan another shot.

An all-new version of the full-size pickup is scheduled to be shown in Detroit in January at the North American International Auto Show.

These spy shots are the clearest photos yet of Nissan’s big pickup. Nissan and Cummins Inc. have already confirmed that a new Cummins-built 5.0-liter turbodiesel V-8 will be an optional engine in the redesigned Titan. That engine will have at least 300 hp and 500 pounds-feet of torque.

The styling of the second-gen Titan appears to borrow liberally from the Ram playbook, with larger headlights placed lower down on the front fenders, big-rig style and a much larger grille. Automotive News reported in July that the revamped truck will come in three cab configurations: crew, extended and, for the first time, a regular cab.

The 2016 Titan is scheduled to arrive late next year. The new Titan arrives just as Ford will be hitting its stride with the new F-150. If cheap fuel prices last until the Titan arrives, that could give the truck a boost.

Earlier this year, Fred Diaz jumped from Chrysler, where he headed Ram, to Nissan as the Japanese automaker’s senior vice president for sales, marketing and operations. Diaz, in a visit to Automotive News in February, said he requested a few changes to the next Titan and said he believes the truck will be competitive with domestic models.
