The F-Series is a series of full-size pickup trucks from Ford Motor Company sold for over five decades. The most popular variant of the F-Series is the F-150. It was the best-selling vehicle in the United States for 23 years and has been the best-selling truck for 31 years, although this does not include combined sales of GM pickup trucks. Analysts estimate that the F-Series alone makes up half of the Ford Motor Company’s profits in recent years. In the 10th generation of the F-series, Ford split the F-150/F-250& F-250/350 into two different body styles. The new F-250/F-350 and as of 2007 F-450/F-550 is called the Super Duty.
