In 2017, do vehicle segment labels even have any meaning anymore? Back in the dark ages of the 1970s we knew what a sport utility vehicle was. It was essentially a shortened body-on-frame pickup truck with an enclosed, but often removable rear body. But then in 1984, Jeep introduced the XJ Cherokee and it all began to change. Now a utility vehicle can be whatever an automaker’s marketing department deems it to be including a high-performance compact, hot hatch like the Mercedes-AMG GLA45.
