In 1966, The Rover Company achieved more success as the production of Land Rover vehicles reached the 500,000 mark. A year later, the Rover Company merged with Leyland Motors and a six-cylinder 2.6-liter engine is made available on their vehicles. By 1968, Leyland and Rover joined the British Motor Corporation (BMC).
In 1970, the company introduced one of the most famous vehicles of all time: the Range Rover. It became the core brand of the future and featured an all-alloy 3.5-liter petrol engine and new styling and design cues. A year later, the Range Rover received the RAC Dewar Award for outstanding technical innovations and the same year 750,000 units of the Land Rover were manufactured.
By 1975, British Leyland fell into financial debt and was taken under state control to prevent it from bankruptcy. Finally, in 1978, the assets were separated and Land Rover Limited was created, which meant that for the first time the company was under independent management. In 1981, the 4-Door Range Rover was released and production exceeded 1 million. In 1985, Land Rover Ninety made its debut with automatic gearbox improvements.
