Ford asserts that it built its Super Duty truck because of the many demanding tasks it must handle at the job site, from heavy loads to muddy terrain. According to the automaker, it built its F-150 with 375 horsepower for working hard during big storms. The Ford Ranger is said to be built with the Terrain Management System for all of the different roads you could drive down in your truck. The automaker credits its vehicles' build quality as the reason it has become the best selling brand in the United States. For a limited time, customers can receive special leasing on select models.
