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 Type M100 from 1989 to 1995, is also commonly known as the 1990s Elan.

 alloy twin-cam head. This Lotus-Ford 4-cylinder engine would go on to be used in a number of Lotus production and racing models.

An Elan +2 was introduced in 1967 with a longer wheelbase and two more rear seats. The Elan +2 embodied the Lotus spirit: It was a fast and agile sport coupe, with very elegant lines. It combined the performance and reliability of the Elan "Coupe" with genuine 2+2 passenger comfort. Tested maximum power: 108-126 bhp (net) (depending on the model); top speed: 120 mi/h, 0-60 mph in 7.9 seconds, 0-100 mph 21.8 seconds. 5,200 Elans +2 were made: less than 1,200 of these cars remain in the roads today. Their relative rarity, beautiful lines, impressive performance and practicality are the main factors for the rising interest on these cars among collectors.

The Elan ceased production in 1973 and the Elan +2 in 1975. An estimated total of 17,000 original Elans and Elans +2 were built. Because of its successful design and technological sophistication, the Elan went on to become Lotus' first commercial success, reviving a company stretched thin by the more exotic and less commercially successful Elite, and enabling funding of the Lotus success in racing over the next ten years.

's design for the Type M100 was approved and work began by Lotus engineers to turn the clay styling buck into a car that could be built. This process was completed in just under three years, a remarkably short time from design to production car.

Testing

The M100 Elan was conceived as a mass-market car and in particular one that would appeal to US buyers. Consequently, Lotus put an enormous effort (for such a small firm) into testing the car; over a two-year period 19 crash cars and 42 development vehicles were built, logging nearly a million test miles in locations from Arizona

The M100 Elan's cornering performance was undeniable (on release the Elan was described by Autocar

 magazine as "the quickest point to point car available"). Press reaction was not uniformly positive, as some reviewers found the handling too secure and predictable compared to a rear wheel drive car. However, the Elan's rigid chassis minimised roll through the corners and has led to its description as 'the finest front wheel drive [car] bar none'. Unlike the naturally aspirated version, the turbocharged SE received power steering as standard, as well as tyres with a higher ZR speed rating.

Engine

Sales

Two variants were available at launch, the 130 bhp Elan 1.6 (retailing at £17,850) and the 162 bhp Turbo SE (£19,850). Initial sales were disappointing, perhaps because its launch coincided with a major economic recession in the UK and USA, and perhaps also because it coincided with the cheaper Mazda MX-5

 which was arguably similar in concept, though the MX-5 was quite intentionally nostalgic and old fashioned (apeing the original Elan), while the M100 was deliberately futuristic, modern and forward looking. The Elan was regarded as a good product in a bad market, but was also very expensive to make (the cost to design and produce the dashboard alone was more than the total cost of the Excel production line), and sales figures were too low to recoup its huge development costs.

, its new owners had no interest in continuing manufacture of the loss-making Elan.

Altogether 3,855 Elans were built between November 1989 and July 1992, including 129 normally aspirated (non-turbo) cars. 559 of them were sold in the US, featuring a 'stage 2 body' which had a different rear boot spoiler arrangement together with a lengthened nose to accommodate a USA-compliant crash structure and airbag, and 16-inch wheels (optional in most markets, standard in the U.S.) instead of 15-inch as on the UK model.

 era (produced June 1994–September 1995) when it was discovered that enough surplus engines were available to make this possible. According to Autocar magazine, the S2 addressed some of the concerns over handling, but power was reduced to 155 bhp and the 0–60 acceleration time increased to 7.5 seconds, due to the legislative requirement to fit a catalytic converter

Korean reintroduction

 bought all the relevant license of Elan from Lotus to manufacture their own version. Outwardly, the Kia version looks almost identical to the original. The most obvious difference is the different taillights, of a somewhat busier design than the original Lotus units. Through 1996 to 1999, Kia Motors built the car as the Kia Elan for the Korean market, using a 151 hp 1.8 L T8D engine instead of the Isuzu-made 1.6.
