Lotus Cars is a British manufacturer of sports and racing cars based at Hethel, Norfolk, England. The company designs and builds race and production automobiles of light weight and high handling characteristics.

History

The company was formed as Lotus Engineering Ltd. by engineer Colin Chapman, a graduate of University College, London, in 1952. The first factory was in old stables behind the Railway Hotel in Hornsey. Team Lotus, which was split off from Lotus Engineering in 1954, was active and competitive in Formula One racing from 1958 to 1994. The Lotus Group of Companies was formed in 1959. This was made up of Lotus Cars Limited and Lotus Components Limited which focused on road cars and customer competition car production respectively. Lotus Components Limited became Lotus Racing Limited in 1971 but the newly renamed entity ceased operation in the same year. [1]

The company moved to a purpose built factory at Cheshunt in 1959 [2] and since 1966 the company has occupied a modern factory and road test facility at Hethel, near Wymondham. This site is the former RAF Hethel base and the test track uses sections of the old runway.

Chapman died of a heart attack in 1982, at the age of 54, having begun life an inn-keeper's son and ended a multi-millionaire industrialist in post-war Britain. The carmaker built tens of thousands of successful racing and road cars and won the Formula One World Championship seven times. At the time of his death he was linked with the DeLorean scandal over the use of government subsidies for the production of the De Lorean DMC-12 for which Lotus had designed the chassis.

In 1986 the company was bought by General Motors. On August 27, 1993, GM sold the company, for £30 million, to A.C.B.N. Holdings S.A. of Luxembourg, a company controlled by Italian businessman Romano Artioli, who also owned Bugatti Automobili SpA. In 1996 a majority share in Lotus was sold to Perusahaan Otomobil Nasional Bhd (Proton), a Malaysian car company listed on the Kuala Lumpur Stock Exchange.

The company also acts as an engineering consultancy, providing engineering development—particularly of suspension—for other car manufacturers. The lesser known Powertrain department is responsible for the design and development of the 4 cylinder Eco-Tec engine found in many of GM's Vauxhall, Opel, Saab, Chevrolet, and Saturn cars. It should however be noted that the current Lotus Elise and Exige models use the 1.8L VVTL-i I4 from Toyota's late Celica GT-S and the Matrix XRS.

The company is organized as Group Lotus, which is divided into Lotus Cars and Lotus Engineering. Contrary to some rumours, there are no plans to create a Formula One Team. This is more likely to be due to the massive financial input required over and above any of the company's wishes.

Michael Kimberley took over as Acting Chief Executive Officer of the Company and its Group from May 2006. He currently chairs the Executive Committee of Lotus Group International Limited ("LGIL") established in February 2006, with Syed Zainal Abidin (Managing Director of Proton Holdings Berhad) and Badrul Feisal (non-executive director of Proton Holdings Berhad). LGIL is the holding company of Lotus Group Plc.

Formula One

Main article: Team Lotus
Lotus 77

The company encouraged its customers to race its cars, and itself entered Formula One as a team in 1958. A Lotus Formula One car driven by Stirling Moss won the marque's first Grand Prix in 1960 at Monaco in a Lotus 18 entered by privateer Rob Walker. Major success came in 1963 with the Lotus 25, which—with Jim Clark driving—won Lotus its first F1 World Constructors Championship. Clark's untimely death — he crashed a Formula Two Lotus 48 in April 1968 after his rear tyre failed in a turn in Hockenheim — was a severe blow to the team and to Formula One. He was the dominant driver in the dominant car and remains an inseparable part of Lotus' early years. That year's championship was won by Clark's teammate, Graham Hill.

Lotus is credited with making the mid-engined layout popular for Indycars, developing the first monocoque Formula 1 chassis, and the integration of the engine and transaxle as chassis components. Lotus was also among the pioneers in Formula 1 in adding wings and shaping the undersurface of the car to create downforce, as well as the first to move radiators to the sides in the car to aid in aerodynamic performance, and inventing active suspension.

Even after Chapman's death, until the late 1980s, Lotus continued to be a major player in Formula 1. Ayrton Senna drove for the team from 1985 to 1987, winning twice in each year and achieving 17 pole positions. However, by the company's last Formula 1 race in 1994, the cars were no longer competitive. Lotus won a total of 79 Grand Prix races. During his lifetime Chapman saw Lotus beat Ferrari as the first team to achieve 50 Grand Prix victories, despite Ferrari having won their first nine years sooner.

Formula One Constructors' Championships (Drivers' Championship winner for Lotus)

Team Lotus established Classic Team Lotus in 1992, as the Works historic motorsport activity. Classic Team Lotus continues to maintain Lotus F1 cars and run them in the FIA Historic Formula One Championship and it preserves the Team Lotus archive and Works Collection of cars, under the management of Colin Chapman’s son, Clive.

  • Lotus Elan M100 - The second car that used the Elan name, released in 1989. It was a technical tour de force but one that also defied Lotus' 'performance through light weight' tradition, to its detriment. The idea of a front-drive Lotus, powered by a Japanese turbo-charged engine, was a brave concept and its cornering performance was undeniable. But the handling was negatively compared to the original Elan by some Lotus loyalists and its relatively high price (vs., e.g., the Mazda MX-5) meant that it was not a sales success.
  • Lotus Europa - 1966-1975 mid-engine sports car.
  • Lotus Esprit - A mid-engined sports car, launched in the early 1970s. It was styled by Italian designer Giorgetto Giugiaro. The Esprit started with a light, 4-cylinder design, which went through several iterations of turbo-charging and electronic upgrades, before finally being replaced by a highly-advanced V8. The last Lotus Esprit rolled off the production line on 20 February, 2004, after 28 years in production. A total of 10,675 Esprits were built since production began in 1976.
  • Lotus M250 - (2000) Concept car that never reached production

Current

The Lotus Elise
  • Lotus Elise - The Elise incorporates many engineering innovations, such as an aluminum extrusion frame and a composite body shell. The Elise has also spawned several racing variants, including an exotic limited series called the 340R, which has an open-body design echoing the famed Seven. The Elise was recently introduced into the U.S., with a Toyota engine, in order to pass strict U.S. emissions laws. The 1ZZ & 2ZZ Toyota engines used have a Lotus ECU with their own fuel mapping. Also see the related Tesla Roadster below. The supercharged Lotus SC and limited edition Jim Clark Type 25 Elise editions add a new performance dimension to the Elise range. 0-60 acceleration is in 4.3 seconds and 0-100km/hr in 4.6 seconds.
  • Lotus Eco Elise is a version of its classic sports car that incorporates solar panels into a roof made from hemp, while also employing natural materials in the body and interior of the car.
  • Lotus Exige - A version of the Lotus Elise with a redesigned body to provide additional downforce (100 lb at 100 mph)[4]. Additionally, the following Elise Sport Pack and Hardtop options are standard on the Exige. The car is street legal and the base 2006 model was available in The USA for $50,990[5]. Lotus updated the Exige with the supercharged Exige S in 2007.
  • Lotus Exige S - An Exige with a supercharged engine providing 220 hp[6]. The non-S Exige[7] and Elise[8] have 190 hp (140 kW).
Lotus Europa S
  • Lotus Europa S - The Grand Tourer (GT)-inspired two-seater is claimed to offer a more upmarket sportscar experience, although it is based on the same chassis as the Elise and Exige, limited accommodation and practicality. Power comes from a Lotus-tuned variant of the turbocharged four-cylinder engine which powers the VX220. The Europa has been criticised in the motoring press for being expensive and for lacking equipment and practicality compared to rivals like the Porsche Cayman.
  • Lotus Evora Launched 22 July, 2008. Code named Project Eagle during development. A 2+2 sports car with a mid mounted, transverse 3.5 litre V6 engine.[9]
Lotus 2-Eleven
  • Lotus 2-Eleven Weighing just 670 kg (1,480 lb) and with 252 bhp (188 kW) the Lotus 2-Eleven can sprint from 0-60 in 3.8 seconds and has a top speed of 155 mph (249 km/h). Intended as a track day car it costs £39,995 but for an additional £1,100 Lotus will make the car fully road legal.
Lotus Exige 265E

Projects undertaken by Lotus Engineering

Lotus Engineering Limited, is an offshoot of Lotus Cars, which engineer cars for third party companies. Examples are shown here:-

  • Lotus Cortina—Lotus version of the famed Ford Cortina Mk. I.[citation needed]
  • Lotus Talbot Sunbeam—Talbot's hot-hatch rally car of the early '80s.
  • Vauxhall Lotus Carlton (also Opel Lotus Omega, internal name Lotus Type 104) - At the time (early 1990s) this was the fastest saloon car available, with a top speed of over 170 mph (274 km/h).
  • The 1991 Dodge Spirit R/T with a version of the 2.2 L K-car engine with a 16-valve DOHC head designed by Lotus with over 220 hp (160 kW).
  • Vauxhall VX220 (also Opel Speedster) - Lotus produced and based upon the same aluminium chassis design as the Lotus Elise. Production of these models ended in 2005
  • Lotus styled and assisted with the engineering of the Tesla Roadster, an electric sports car, as well as licensing some technologies to Tesla Motors and constructing the Roadster at their plant in Hethel. [1]
  • Lotus was responsible for most of the design, development, and testing, of the LT5 DOHC V8 powerplant for the Chevrolet Corvette ZR-1.
  • Lotus designed, developed and tested the GM Ecotec engine and its variants.
  • Lotus was responsible for various aspects of the Sinclair C5 electric tricycle.
  • Lotus was responsible for the suspension calibration of the Toyota MR2 Mk. I, the Toyota Supra Mk. II and Mk. III, the Isuzu Piazza, the Isuzu Impulse as well as newer Proton models.
  • Lotus was responsible for the development of the Campro engine together with Proton[10], as well as its variable valve timing system, the Cam Profile Switching (CPS). Currently available in the 1.6-litre and 1.3-litre variants, the Campro engine now powers most of Proton's newer models.
  • Lotus has worked on the suspension of the Mahindra Scorpio to make it more stable at high speeds.
  • Lotus is partnering with ZAP on the design of their next electric vehicle, the ZAP-X, based on the APX concept vehicle.
  • Lotus produced the revised Chassis of the Isuzu Piazza
  • The Dodge EV electric vehicle from Chrysler is based on a Lotus Europa S chassis.

Lotus engines

Lotus Engineering

In 2000, Lotus Engineering, Inc. was established in Ann Arbor, MI as it's US headquarters.

APX and VVA

Main article: Lotus APX

The APX (also known as the "Aluminium Performance Crossover") is an aluminium concept vehicle revealed at the 2006 Geneva Motor Show built on Lotus Engineering's Versatile Vehicle Architecture (VVA).

Whereas the VVA technology will be used in the creation of a new mid-engined sportscar for Lotus cars, the APX is in fact a high performance 7 seat MPV with four-wheel drive and a front mounted V6 engine from Lotus Engineering's Powertrain division. The engine was designed and developed to be available as a 2.2 litre N/A and 3.0 litre supercharged. A number of prototypes of both engines exist in full working order in a number of mule cars.

Versatile Vehicle Architecture (VVA) is an effort by the Lotus car manufacturing company to reduce the investment needed for producing unique, niche-market cars by sharing a number of common components.

Cars produced using VVA:

Vehicles

On September 20, 2007 Lotus Engineering released a five year construction plan in which new models would be created in the United States.[citation needed] It also states that there will be a rapid expansion of the US Lotus Engineering Program. Three new models are to be created around the 2010 year period, a 2+2 coupe, a brand new Lotus Excel, and of course the 2009 Esprit.

Electric vehicles

Lotus Engineering has established a group dedicated to hybrid and electric vehicles. [11]

Lotus plans to enter the electric vehicle race, CEO Michael Kimberley told the Financial Times . "Don’t be surprised to see an electric Lotus shortly,” he said, adding that a concept version could debut as early as March 2009, at Geneva Motor Show[12][13]. Lotus is now front and center in the electric-car arena.[14]

Lotus did not reveal details about the car or the engine but discloses that it will go for 300 to 400 miles (640 km) and it will really live up to the expectations of being one of the best electric cars in the world [13].

Lotus joined Jaguar Cars and Caparo on a luxury hybrid executive sedan project called "Limo-Green"--funded by the UK Government Technology Strategy Board. The vehicle will be a series plug-in hybrid.[14]

Tesla Motors, a likely rival for Lotus if its plans go through, has also turned to contractors for parts of the all-electric Roadster [12]. Of note however, is the fact that Tesla currently obtains the bodies for their Roadster from Lotus as do Dodge for their EV because of the heavy weight of the batteries in an EV and Lotus's widely known low weight and sharp handling characteristics. While only 10% of the parts of the Tesla Roadster are shared with the Lotus Elise, Lotus is responsible for approximately 40% of the overall content of the car.[12].
