A specially modified Special Service Vehicle version is also available from Ford Fleet for law enforcement agencies, fire departments, and EMS agencies. Part-time four-wheel drive is an available option, and since 1995 this has been a 'shift on the fly' system with full protection against being engaged at high speed. Both two-door Explorer Sport and four-door models of Explorer have been sold. The Explorer has also been involved in controversy, after a spate of fatal rollover accidents involving Explorers fitted with Firestone tires. It is marked as a mid-sized crossover SUV and is slotted between the larger Ford Expeditionand the smaller Ford Escape. The Ford Explorer was instrumental in turning the SUV from a special-interest vehicle into one of the most popular vehicle types on the road. It is manufactured in Chicago, Illinois (it was also assembled in Hazelwood, Missouri until the plant closed on March 10, 2006).


The Ford Explorer is a sport-utility vehicle sold in North America and built by the Ford Motor Company since 1990, as a replacement for the smaller but related Ford Bronco II.
