The 2016 Nissan Titan XD will have a diesel engine, according to AutoBlog. Other Nissan Titan models and model years use gasoline engines that cannot run on diesel.
The 2016 Nissan Titan XD engine is manufactured by Cummins through a manufacturing agreement held between the two companies. Based on existing power train designs, the engine is aimed at filling the medium-duty niche that the Titan XD is marketed towards. V6 and V8 gasoline engines will also be available for the Titan XD. However, details on these engines have yet to be released by the company. The exact release date for the truck is currently unknown.
