Jaguar Land Rover is exhibiting pivotal cars from its history, including the C-X75 hybrid supercar concept, through 14 July as part of the Coronation Festival of events at Buckingham Palace. Among the vehicles is a 1949 Land Rover Series I, a 1961 Jaguar E-Type and a 1974 Range Rover used in royal transportation. Earlier this week, Jaguar showed the Project 7 Concept, built in homage to its Le Mans-winning D-Type of the 50s.
