History

Lotus Elan is the name of two convertible cars and one fixed head coupé produced by Lotus Cars. The original Type 26, 26R Racing version (of the S1 Elan), 36R Racing version (of the S2 Elan), 36 Fixed Head Coupe, 45 Drop Head Coupe, and the "Type 50" +2 Coupe, circa 1962 to 1975, are commonly known as the '60s Elans.

The new Elan was a huge hit right away. It was compact, light, quick, and inexpensive, with nimble handling, superb road holding, and excellent driving comfort. The car was notoriously unstable, especially when it came to the electrical system, despite the fact that it was modified and improved over time. These flaws, on the other hand, have been addressed over time. The powerful Sprint Big-Valve variants, notably the well made closed coupés, were the greatest Elan models from 1971 to 1973. In retrospect, the vehicles with the Stromberg carburettor were undoubtedly the poorest choice, but in terms of driving behaviour and technology, the drive was still a generation ahead of the competition. 9,659 copies were printed in just over ten years.

The original Elan was introduced in 1962 as a roadster, although an optional hardtop was offered in 1963 and a coupé version in 1965. The two-seat Lotus Elan replaced the elegant, but unreliable and expensive to produce Lotus Elite.It was the first Lotus road car with a fibreglass body and the now-famous steel backbone chassis. The Elan embodied Colin Chapman's minimum weight design philosophy, weighing in at 1,500 pounds (680 kilogrammes). 

The Elan was also available as a kit to be constructed by the consumer in the beginning. With a 1,498 cc or later a DOHC 1557 cc engine, 4-wheel disc brakes, rack and pinion steering, and 4-wheel independent suspension, the Elan was technologically advanced. The "Lotus TwinCam" engine was based on a Ford Kent Pre-Crossflow 4-cylinder 1498 cc engine with a two-valve alloy chain-driven twin-cam head designed by Harry Mundy. Ford later bought the rights to this concept and dubbed it "Lotus-Ford Twin Cam."It would go on to be used in a number of Ford and Lotus production and racing models. the S2 was replaced by the end of 1964
