Lotus Elan S4 Hexagon Estate

Thursday 4 July 2013
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 Type M100 from 1989 to 1995, is also commonly known as the 1990s Elan.
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 to use the now-famous steel backbone chassis with a fibreglass body. At 1,500 lb (680 kg), the Elan embodied the Colin Chapman minimum weight design philosophy. Initial versions of the Elan were also available as a kit to be assembled by the customer. The Elan was technologically advanced with a twin-cam 1558 cc engine, 4-wheel disc brakes, and 4-wheel independent suspension. The Lotus-Ford Twin Cam engine was based on Ford's Pre-Cross-flow 4-cylinder 1500 cc engine, with a Lotus-inspired Cosworth 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 mph (190 km/h), 0–60 mph in 7.9 seconds, 0-100 mph 21.8 seconds. 5,200 Elans +2 were made: fewer 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.
This generation of the two-seater Elan was famously driven by the character Emma Peel on the British television series The Avengers. In 2004, Sports Car International named the Elan number six on the list of Top Sports Cars of the 1960s. The original version of the car was designed by Ron Hickman, who also designed the first Lotus Europa as part of Lotus' GT40 project bid and made his fortune having designed the Black & Decker Workmate.
The original Elan is usually credited as being the design inspiration for the highly successful 1989 Mazda MX-5 (Mazda Miata in North America). Two Elans were intimately evaluated by Mazda in the process of designing the MX-5.

Lotus Europa

Saturday 16 June 2012
The Lotus Europa is a two door mid-engined GT coupé built by Lotus Cars from 1966 to 1975. In 2006 Lotus began production of a totally new, Lotus Elise-derived design, a mid-engined GT coupé named Europa S.
The original Europa used Lotus founder Colin Chapman's minimalist steel backbone chassis that was first used in the Lotus Elan, while also relying on its fibreglass moulded body for structural strength. The Europa was based on a prototype built to compete for Henry Ford II's contract to build a Le Mans race car in the early 1960s.
The Europa was designed and built to be an embodiment of Chapman's oft-stated philosophy of automotive design: "Simplify, then add lightness."
The four-wheel independent suspension was typical of Chapman's thinking. The rear suspension was a modified Chapman strut, as used for Chapman's earlier Formula racing car designs. Owing to the rubber suspension bushes used to isolate engine vibration from the car body, the true Chapman strut's use of the drive shaft as the lower locating link could not be followed whilst still giving the precise track and handling desired. The forward radius arms were increased in size and rigidity, to act as a semi-wishbone. A careful compromise between engine mounting bush isolation and handling was required, culminating eventually in a sandwich bush that was flexible against shear but stiff in compression and tension. The car's handling prompted automotive writers to describe the Europa as the nearest thing to a Formula car for the road. Aside from the doors, bonnet (hood), and boot (trunk), the body was moulded as a single unit of fibreglass.
In all, Lotus built about 9,300 Europas.

Lotus Esprit V8

Saturday 16 June 2012
The Esprit V8 used Lotus' self-developed all-aluminum, twin-turbocharged (Garrett T3/60 turbos) 90-degree V-8, Code-named Type 918, in front of the same Renault transmission as before with no Chargecooler. Derek Bell developed an uprated gearbox that overcame a lot of the gearbox problems with a much thicker single piece input shaft. The Type 918 engine was detuned from a potential 500 bhp to 350 bhp (261 kW; 355 PS) to prevent gearbox damage due to the fragility of the Renault UN-1 transmission. In period tests, zero to sixty miles per hour came in at 4.4 seconds and top speeds of over 175 mph were achieved. Early Type 918 engines built between 1997 to 2000 are noted to suffer from a leaking cylinder liner problem due to a breakdown in the liner sealant if the engine overheats, resulting in water leaking into the cylinders and ending up in the sump. After extensive testing, this problem was rectified with a change of sealant type from Loctite 572 to Hylomar 3400, although some owners still reported sporadic leaking cylinder liners.
Alongside V8 models was produced the GT3, a turbocharged four-cylinder car with the type 920 2.0 L chargecooled and turbocharged engine which had been used only in Italian market cars previously.
In 1998 the V8 range was split into SE and GT specifications, both cars with a much changed interior configuration, both offering similar performance with the SE being the more luxurious of the two.
The ultimate incarnation of the Esprit came in 1999 with the Sport 350. Only 50 were made, each offering 350 horsepower (as per the name) and various engine, chassis and braking improvements, like the addition of AP Racing brakes, stiffer springs and a revised ECU. Several visual changes were made as well, including the addition of a large carbon fiber rear wing on aluminium uprights in place of the standard fibreglass rear wing. By this time the Esprit could reach 60 mph (100 km/h) in 4.3 seconds as well as reaching 0-100 in 10.1 seconds, and weighed 1,300 kg (2,866 lb) as a result of many modifications.
Esprit production temporarily ceased in 2004 with Lotus content on producing the Esprit with little development aside from minor cosmetic changes including a switch to four round tail lights for the 2002 model year. Currently, after 28 years, a total of 10,675 Esprits have been produced and a new version is slated to make an appearance nine years after the last one rolled off the assembly line at Hethel in February 2004.

Lotus Esprit

Wednesday 30 March 2011
The Lotus Esprit is a sports car that was built by Lotus in the United Kingdom between 1976 and 2004, as well as a future release in 2013. The silver Italdesign concept that eventually became the Esprit was unveiled at the Turin Motor Show in 1972 as a concept car, and was a development of a stretched Lotus Europa chassis. It was among the first of designer Giorgetto Giugiaro's polygonal "folded paper" designs. Originally, the name Kiwi was proposed, but in keeping with the 'E...' naming format of Lotus tradition, the name became Esprit.
The Esprit was launched in October 1975 at the Paris Auto Show, and went into production in June 1976, replacing the Europa in the Lotus model lineup. These first cars eventually became known as S1 (or Series 1) Esprits. With a steel backbone chassis and a fiberglass body, the Esprit was powered by the Lotus 907 4 cylinder engine, as previously used in the Jensen Healey. This engine displaced 2.0 L, produced 160 bhp (119 kW; 162 PS) in European trim (140 bhp (104 kW; 142 PS) in US/Federal trim), and was mounted longitudinally behind the passengers, as in its predecessor. The transaxle gearbox was a 5 speed manual unit, previously used in the Citroën SM and Maserati Merak; it featured inboard rear brakes, as was racing practice at the time. The Series 1 embodied Lotus’ performance through light weight mantra, weighing less than 1,000 kg (2,205 lb).
The original Esprit was lauded for its handling and is said to have the best steering of any Esprit. However, it was generally regarded as lacking power, especially in markets such as the United States where the engine was down-rated for emissions purposes. Lotus’ claim of 0-60 mph in 6.8 seconds and a top speed of 138 mph (222 km/h) may be thought of as optimistic - actual road test times indicated 0-60 mph in 8 seconds and a top speed of around 133 mph (214 km/h).
1977 S1 (modified into "submarine" mode), as seen in the film The Spy Who Loved MeThe S1 Esprit can be distinguished from later Esprits by a shovel-style front air dam, Fiat X1/9 tail lights, lack of body-side ducting, and Wolfrace alloy wheels. Inside the car, the most obvious indication of an S1 Esprit is a one-piece instrument cluster with green-faced Veglia gauges.
The car gained fame through its appearance in the James Bond film The Spy Who Loved Me (1977) where it was featured in a long chase sequence, converting into a submarine.
A series of improvements made to the Esprit during its initial run culminated in the S2 (or Series 2) Esprit, which was introduced in 1978. The most obvious of these changes are intake and cooling duct "ears" located behind the rear quarter window, tail lights from the Rover SD1, and an integrated front spoiler. S2 Esprits also used 14-inch (360 mm) Speedline alloy wheels designed specifically for Lotus. Other changes included relocating the battery from above the right side fuel tank (under the rear quarter window) to the rear of the car, adding an access door to the engine cover, as well as replacing the instrument cluster made by Veglia with individual gauges made by Smiths and using different style of switches on the dashboard.
During this era, special edition cars were made to commemorate Lotus's racing victories. Sharing the black and gold colour scheme of Lotus' then F1 sponsor, John Player & Sons, these cars are commonly known as the John Player Special (JPS) Esprits. Lotus' records of production figures are notoriously vague, however best estimates suggest that 149 JPS Esprits were produced.
The S2.2 was produced as a stop-gap model in 1980, almost identical to the S2 but with an enlarged (2.2 L) type 912 engine used. This kept horsepower the same, but bumped up torque from 140 lb·ft (190 N·m) to 160 lb·ft (217 N·m). Importantly, the S2.2 also introduced the use of a galvanised chassis. These cars are extremely rare even among Esprits and only 88 are thought to have been produced.
