Nissan took the wraps off its long-awaited 2016 Titan XD pickup, which the company said is but the first of a new generation of Titan models. Unveiled at the 2015 North American Int'l Auto Show in Detroit this week, the 2016 Titan XD is powered by a new Cummins 5.0-liter V8 Turbo Diesel that cranks out 310 hp and 555 lb-ft of torque. The OEM said the new Titan XD is projected to go on sale at Nissan dealers nationwide in late 2015.
