(June 13, 2018) As hard as it may be to believe, BMW’s X5 is 20 years old and about to enter its fourth generation. Built exclusively in BMW’s Spartanburg, S.C., assembly plant, more than 2.2 million units of the sport utility have been sold globally in that period, with more than 720,000 of those sales in the U.S. It was BMW’s first SUV, and has since been joined in Spartanburg by the X3, X5, and X6. A range-topping X7 will join the party soon.
