Rover was a British automotive marque used between 1904 and 2005. It was launched as a motorcycle company called the Rover Company in 1878, before manufacturing cars in 1904. The brand used the iconic viking longship as its logo.

Despite a state-controlled absorption by the Leyland Motor Corporation (LMC) in 1967 and subsequent mergers, nationalisation and de-mergers, the Rover marque retained its identity first as an independent subsidiary division of LMC, and then through variously named groups of British Leyland through the 1970s and into the 1980s.

The Rover marque became the primary brand of the then newly renamed Rover Group in 1988 as it passed first through the hands of British Aerospace and then into the ownership of BMW Group. Technological know-how gained from Honda and financial investment during the BMW ownership led to a revival of the Rover marque during the 1990s in its core midsize segment.

In 2000, BMW sold the Rover and related MG car activities of the Rover Group to the Phoenix Consortium, who established the MG Rover Group at Longbridge. BMW retained ownership of the Rover marque, allowing MG Rover to use it under licence. In April 2005, Rover branded cars ceased to be produced when the MG Rover Group became insolvent.

An automobile, autocar, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.

The term motorcar has also been used in the context of electrified rail systems to denote a car which functions as a small locomotive but also provides space for passengers and baggage. These locomotive cars were often used on suburban routes by both interurban and intercity railroad systems.

There are approximately 600 million passenger cars worldwide (roughly one car per eleven people). Around the world, there were about 806 million cars and light trucks on the road in 2007; the engines of these burn over a billion cubic meters (260 billion US gallons) of petrol/gasoline and diesel fuel yearly. The numbers are increasing rapidly, especially in China and India.
