Chronology
Predecessor Lotus Seven

The Caterham 7 (or Caterham Seven) is a super-lightweight sports car produced by Caterham Cars in the United Kingdom. It is based on the Lotus Seven, a lightweight sports car sold in kit and factory-built form by Lotus Cars, from 1957 to 1972.

After Lotus ended production of the Lotus Seven, Caterham bought the rights to the design, and today make both kits and fully assembled cars. The modern Caterham Seven is based on the Series 3 Lotus Seven, though developed to the point that no part is the same as on the original Lotus.

Various other manufacturers offer a sports car in a similar basic configuration, but Caterham owns various legal rights to the Lotus Seven design and name. The company has taken legal action in the past in order to protect those rights, although in South Africa, it lost its case against Birkin on the basis that it never obtained the claimed rights from Lotus.

Colin Chapman had been a Royal Air Force pilot, studied structural engineering and went on to become one of the great innovators in motorsports design founded Lotus Engineering Ltd. His vision of light, powerful cars and performance suspensions guided much of his development work with the basic design philosophy of, "Simplify, then add lightness". His Lotus 7 had its debut at the 1957 Earl’s Court Motor Show in London. They were priced at £1,036 including purchase tax but it cost only £536 in kit form as no purchase tax was required. It weighed only 725 lb (329 kg). Fast and responsive, the Lotus 7 was one of Chapman’s masterworks, an advanced machine that surpassed the earlier Lotus 6 as a vehicle that could perform well on the track and be driven legally on the road.

In 1973, Lotus decided to shed its kit car image and concentrate on limited series motor racing cars and up-market sports cars. As part of this plan, it sold the rights to the Seven to its only remaining agents, Caterham Cars in England and Steel Brothers Limited in New Zealand. At the time the current production car was the Series 4, but when Caterham ran out of the Lotus Series 4 kits in 1974 they introduced its own version of the Series 3, as the Caterham Seven. The modern day Roadsports and Superlights (in "narrow-bodied chassis" form) are the direct descendants of this car and therefore of the original Lotus 7.
