The fourth generation Range Rover was introduced in 2013. Known as the Series 4, the fourth gen Range Rover saw an updated all aluminum monocoque, which was a first for SUVs. Alongside a range of V6 and V8 engines, the Series 4 introduced a hybrid option that paired an inline four engine with an electric motor. The top of line variant of the Series 4 is the SVAutobiography, which featured a supercharged 5.0L V8 engine.
