Chrysler has committed to building a third SUV at its Jefferson North plant for its Maserati brand, but CEO Sergio Marchionne stopped short of saying when the plant will need a third shift to make it.

“As soon as we see how well the (Dodge) Durango does,” Marchionne said today at Chrysler’s Sterling Heights assembly plant. “It will take a while before we can bring the Maserati SUV in and that will require separate treatment anyway because of the quality of the interior and the powertrains which are fundamentally Ferrari-based.”
