The Land Rover Series I are off-road vehicles produced by the British manufacturer Rover Company that were inspired by the US-built Willys Jeep.
Land Rover entered production in 1948 with what has later been termed the "Series I", which was launched at the Amsterdam Motor Show. It was originally designed for farm and light industrial use, with a steel box-section chassis and an aluminium body.
Originally the Land Rover was a single model offering, which from 1948 until 1951 used an 80-inch (2.03 m) wheelbase and a 1.6-litre petrol engine. This incorporated an unusual four-wheel-drive system, with a freewheel unit that disengaged the front axle from the manual transmission, allowing a form of permanent 4WD. A ring-pull mechanism in the driver's footwell allowed the freewheel to be locked to provide more traditional 4WD. This was a basic vehicle: tops for the doors and a roof (canvas or metal) were optional extras. In 1950, the lights moved from a position behind the grille to protruding through the grille.
