Like a stone on the bottom of a rushing river, the Land Rover Range Rover Sport has been growing smoother every year. When it first debuted back in 2005, it looked as aerodynamic as a brick — all sharp edges, hard lines and rectilinear forms. The second generation that arrived in 2013 was still boxy, but the edges had been sanded down. By 2022, when the third-gen version launched, it looked as slippery as a worn bar of Dial.
