While these lines are being written, the Jeep Grand Cherokee as we now know it continues its existence, though it has lost its diesel engine and its Overland edition, which has been replaced by the North version. But a new entirely revised and redesigned Grand Cherokee will be marketed sometime over the course of the year. It will accommodate five or seven people, and will be powered by a V6 engine they say is 11% more fuel-efficient than the present engine.
