The Ford Expedition is a full-size SUV introduced in 1996 for the 1997 model year as a replacement to the Bronco. It is Ford's largest and last truck-based, off-road and tow-capable SUV. The Expedition is based on the Ford F-150 pickup and shares various components. The Expedition offered up to nine-passenger seating in model years before 2007 (with a front bench seat option); 2007–present has bucket seats in the first row. A modified Special Service Vehicle version is available for law enforcement agencies, fire departments, and emergency medical services. Remote keyless entry is a standard feature on all models of the Ford Expedition.
