For 2011, BMW has revised the fourth-generation X5's now all-turbo engine offerings and added a standard eight-speed automatic to a vehicle that reportedly contains nearly 4,000 parts that are all new. And thanks to some pretty remarkable work at the company's Spartanburg, South Carolina plant, production of the new model commenced over the course of a single weekend. In short, BMW utilized a process that it calls "digital changeover" to stop production of the 2010 X5 on March 19 without slowing production at all, and just two days later on March 22, production examples of the 2011 model were flowing down the assembly line.
