Manufacturing
The all-new 2011 Jeep Grand Cherokee will be built at the 2.7-million-square-foot Jefferson North Assembly Plant (JNAP) in Detroit, which has been the site of Jeep Grand Cherokee production since its introduction in 1992.
In preparation for production of the all-new Jeep Grand Cherokee, Jefferson North Assembly is undergoing a 285,000-square-foot expansion to replace the existing body shop, which is part of Chrysler's investment of approximately $1.8 billion in new vehicle programs.
In addition, changes throughout paint and assembly operations will give the facility an all-new level of manufacturing flexibility for multiple product capability.
