Chrysler CEO Sergio Marchionne has confirmed plans to build a new Ram Dakota (formerly Dodge Dakota).

Speaking to journalists at the North American International Auto Show, Marchionne said there is a "better than 50-percent chance" the model will have unibody construction. This will likely upset the purists, but it could enable the truck to be lighter and more fuel efficient.

Engine options remain a mystery, but the executive hinted there could be a diesel engine from the Jeep Grand Cherokee.

There's no word on when the Dakota will be launched, but previous reports have indicated it could show up in late 2013 or early 2014.
