Template:Infobox company

Caterham Cars is a manufacturer of specialist lightweight sports cars established in Caterham, Surrey, UK, with their headquarters in Crawley, Sussex, UK. Their current model, the Caterham 7 (or Seven), is a direct evolution of the Series 3 Lotus Seven designed by Colin Chapman and originally launched in 1973. In the 1990s the company made the Caterham 21,a two-seater soft top alternative to the MGF and Lotus Elise, (which both sold many more units). A track-only car, the SP/300.R, a joint project with Lola was released for customer testing in 2010 and is scheduled for release in 2013. On 27 April 2011, the Malaysian Formula One team owner Tony Fernandes announced that he had purchased Caterham.<ref name="">Template:Cite web</ref><ref name="">Template:Cite web</ref>


Lotus origins

Template:Main Colin Chapman's Lotus Cars launched the Series 1 Lotus Seven in 1957. The car was immediately embraced by enthusiasts as a low-cost, lightweight sports car and successful race car. Revised Series 2, Series 3 and Series 4 versions were subsequently launched in 1960, 1968 and 1970 respectively.

Caterham Cars had been a major Lotus 7 dealer during the 1960s, and its founder, Graham Nearn, purchased the rights to continue manufacture of the Seven design from Chapman in 1973, after Lotus announced its intention to discontinue the model. Caterham initially restarted manufacture of the Lotus Seven Series 4; however, when this proved unpopular, production switched to a Series 3 model in 1974.

The Lotus/Caterham 7 is widely regarded by car enthusiasts and the media as one of the iconic sports cars of the 20th century.Template:Citation needed With 2007 marking the 50th year of continuous production, the Seven still enjoys strong support and success in clubman-style racing.

Since 2006 Caterham Cars has been run by an ex-Lotus management team led by Ansar Ali (CEO) and Mark Edwards (COO). In June 2012 Ansar Ali announced he was to leave Caterham Cars and Graham Mcdonald (the company's former CFO) became the new CEO.


As with its Lotus Seven precursors, Caterhams are constructed of aluminium sheet attached to a tubular steel chassis. Nosecone and wings are either GRP or carbon fibre depending on specification. All Sevens are front engined with rear-wheel drive and two seats. Their extremely high performance is achieved through light weight (less than Template:Convert on some versions) rather than particularly powerful engines. As well as a lightweight chassis and bodywork, Caterham Sevens achieve their very low mass through their lack of comfort and safety oriented features such as a fixed roof, doors, radio, air-conditioning, airbags, traction/stability control, ABS, satellite navigation or cruise control. As a result, the Seven is somewhat limited in its practicality for everyday usage and is instead recognised by driving enthusiasts for its focus on driving enjoyment, making it an ideal track/race car or 'Sunday' car.

Kit format

Chapman and Lotus helped to pioneer the British kit car industry. The Lotus Seven was offered in kit form to allow buyers to avoid new car tax in the UK. Subsequently Caterham continued offering cars in 'complete knock down' (CKD) kit form as the tradition of hand building your own Seven was well established amongst enthusiasts. Today, all Caterham Sevens are still offered in kit form in the UK except the CSR (Series 6) model. Modern Caterham kits differ from the majority of kit cars as all parts are supplied ready to assemble, not requiring a donor car, fabrication or any special skills.

Although the Seven has always been popular with enthusiasts outside of the UK marketplace, export of the Seven to other markets has increasingly been limited by homologation, safety and emissions regulations in the modern era. As a result, the chassis/engine combinations, specifications, pricing and kit-form availability vary widely between countries.

In the past in the United States Caterhams were sold as kits only, lacking some modern safety features required of manufacturers, but which are not required for individually assembled vehicles. Buyers could either choose to construct the cars themselves or pay their regional dealers or local builders to assemble them. Typically the engine and transmission are sourced separately as a unit - often from Caterham - but all other components (including frame, suspension, differential, driveshaft, interior, wiring and instruments) were provided in kit form.

As of 2014, however, Caterham has named Superformance their official distributor in the United States. International demand has increased dramatically in part due to the addition of a F1 Race team and the changes in Caterham's structure focusing on the distribution of the Seven worldwide. Caterham has since introduced a new model line up and focused on their production and production times to better suite their new international market, making their partnership with Superformance possible. Sevens will be shipped to the USA in part-built form and sold as rolling chassis via Superformance’s nationwide dealer network for customers to then complete the build personally or through the Superformance dealership. The initial US line-up includes several Caterham Sevens: 160, 280, 360, 480, and the 620R.

In the UK, the vehicles can be obtained as kits or entirely assembled by Caterham and registered for the road under SVA (Single Vehicle Approval) regulations. In the '60s, the original Lotus Seven was sold only in kit form in both the UK and the US, in order to evade the very high taxes on complete new cars that were not assessed on automobile parts.


Until 1987 the offices, factory and showroom of Caterham Cars were located in the town of Caterham, Surrey, UK.

In 1987, the production and administration of the company moved to a new factory in Dartford, Kent, UK.

Caterham Cars retained a Caterham South showroom and servicing facility in the town of Caterham adjacent to the railway station until February 2013. The Caterham dealership closed after the premises were sold for development and the showroom relocated to temporary facilities in Crawley.<ref name=Dealership>Template:Cite web</ref> Additionally the Caterham Midlands showroom operates outside Leicester.

In 2012 elements of Caterham Cars moved into a new facility in Leafield where it is expected the new models of cars to be produced in the future will be developed and built. The move to this new facility which was formerly used by Arrows F1 team and Super Aguri F1 team, will also accommodate Caterham F1 Team which moved from its original base in Hingham Norfolk.

Caterham 21


In 1994 Caterham also produced a model called the '21'.<ref name="caterham21">Template:Cite web</ref> Mechanically the 21 was very similar to the 7, using a modified 7 spaceframe chassis with a new GRP roadster-style body, including a wrap-around windscreen and fold-away fabric hood (convertible top) manufactured by Oxted Trimming Company.

The 21 benefited from a considerably stiffer setup than a 7, due to the work on the chassis and having a full body. Comfort was introduced in the same minimalist style as the 7, adding just enough to make it a proper roadster without adding too much weight.

Caterham unfortunately underestimated the effort involved in creating a completely new car and took far too long from its inception to deliver the first customer cars, seeing many people who had placed deposits defect to the Lotus Elise and other vehicles. Early ones were used as "prototypes", leaving customers to help iron out some of the foibles of the new car.Template:Citation needed

The 21 never sold particularly well, with only 48 ever made. It had moderate racing success in the Belcar 24 hour series in Europe and is credited with helping Caterham develop the widetrack setup used in SV's (amongst other developments) and the CSR's sweeping interior is reminiscent of the original 21 design.

Caterham SP/300.R


The SP/300.R is a new track-only model designed by Caterham alongside Lola Cars. The SP/300.R is a limited edition with limited production to 25 per annum.

Caterham 7 model line-up



Chassis variants

In 2010 Caterham offers three different chassis variants in the UK.

Series 3 (S3)

The most popular variant retains the same dimensions and layout of the Lotus 7 Series 3.

Series 5 (SV)

Caterham introduced this variant in 2000 to accommodate larger drivers (space is restricted in the S3 for drivers over Template:Convert tall.) Although visually very similar to the S3, the SV is longer, taller and wider and has significantly more space for taller and broader drivers with the added benefits of more luggage space, a larger fuel tank and more stability. The SV chassis is Template:Convert heavier than the S3.

CSR (Series 6)

The CSR was launched in 2005 following extensive research and development by Caterham with the objective of creating an improved Seven. The CSR is based on the larger dimensions of the SV but with a substantially revised and stiffer chassis, inboard 'pushrod' front suspensions, fully independent rear suspension, improved aerodynamics, potent Cosworth engines and a new 'integrated' dashboard layout.

Model/trim variants


The most basic version of the 7 was traditionally offered with a 'live' rear axle but now comes with De Dion rear suspension found in other models of the same range. This trim level strips away all non-essential equipment and comforts.

  • Classic trim is available on S3/SV chassis
  • Engines: 1.4-litre K-Series (105 bhp) or 1.6-litre K-Series (120 bhp).


Roadsport is the trim level intended for general usage, different weather conditions and touring. The spec includes a full windscreen and weather equipment to increase practicality. A large range of performance options are available. The Roadsport dates back to 1996 when it was called the Superlight R, in 1998 a much softer version came out called the Seven Clubsport 1.8. The range continued to be developed in the years as a great alternative to someone who wanted a little bit more than a Classic, but less than a Superlight.

  • Classic trim is available on S3/SV chassis
  • Engines: 1.6-litre Ford Sigma (120,125 or 150 bhp) or 2.0-litre Ford Duratec (175 bhp).
Roadsport A

Roadsport A cars are still ex-Academy cars, with no engine upgrades. However a number of performance upgrades such removing the windscreens and lights, widetrack front suspension and uprated dampers are allowed, as is professional team support. RSA races at the same events as RSB, but has longer 30-minute races.

Roadsport B

Roadsport B is largely for drivers that have come through the previous season's Academy. Some minor modifications are permitted to the car, including fitting a rear anti-roll bar and sticky Avon CR500 tyres. Technical support is still provided by the factory, and professional team support is not permitted. RSB has 20-minute races at 7 or 8 'double-header' meetings over the course of the season, usually all in the UK. For 2009, RSB will be available exclusively to Sigma-engined cars.



The Superlight is intended for track and fast road usage. Superlight spec includes performance options such as carbon bodywork and a close ratio 6-speed gearbox. A wind deflector in place of the windscreen makes a helmet more or less mandatory. The Superlight R400 uses a 2.0 litre Ford Duratec engine tuned to Template:Convert. The R400 name indicates the car's 400 bhp-per-tonne power-to-weight ratio.

  • Superlight trim is available on S3/SV chassis
  • Engines: 1.6-litre Ford Sigma (150 bhp) or 2.0-litre Ford Duratec (175 bhp, 210 bhp or 263 bhp).
Superlight R300

The Superlight R300 is a new class for 2009, designed to bridge the gap between RSA and the existing Superlight R400 class. It is expected to be popular with experienced RSA racers wanting to move on to the next level in speed. 2009 Champion, Jon Walker - DPR Motorsport

Superlight R400

The Superlight R400 series is Caterham Motorsport’s premier British championship. The R400 is a 220 bhp Cosworth powered dedicated race car with a Quaife six-speed sequential gearbox replacing the standard Caterham unit used in the R300. As with all series above Academy, it runs ons Avon CR500 tyres. 2009 Champion Dan Denis, Matt Blyth Racing

Superlight R500

The Superlight R500 series is the latest of Caterham Motorsport's Superlight series of RSA Racing cars. Powered by a 2.0-litre Ford Duratec engine producing maximum horsepower (bhp/rpm) of 263 bhp @ 8500rpm and maximum torque (lb.ft/rpm) of 177 lb.ft @ 7200rpm. With a weight of 506 kg (516 kg) and a sequential gearbox, it is capable of 0-60 mph in 2.88 seconds and a staggering power-to-weight ratio of 520 bhp-per-tonne. Advertised top speed 150 mph. The R500 has been made Top Gear car of the year 2008. In another appearance earlier in the series, it placed fifth on the Power Lap board with a 1:17.9. This time beat the €1,100,000 (£899,000/$1,550,000), 1001 hp Bugatti Veyron.

Superlight R600

In October 2012 a supercharged model for a race-series above the R300-class was released, including slick tyres and a sequential gearbox.

Superlight 620R

In September 2013 Caterham made a car called the 620R. It was based on the R500, but was supercharged. This increased the power output to 310 brake horsepower at 7,700 rpm and the torque to 219lb.ft at 7,350 rpm. It also reduced the 0-60mph time to 2.79 seconds. It has a power-weight ratio of 568 bhp-per-tonne and a top speed of 155mph.



The CSR chassis comes in two basic trims which mirror those of the S3/SV cars. The 'basic' CSR has a road and touring oriented spec with full windscreen and weather equipment. This is available as the CSR200 (200 bhp) or CSR260 (260 bhp). The CSR Superlight (also 260 bhp) is the current Caterham performance flagship strips away the windscreen, integrated dash and other comfort-oriented components for maximum performance, with specialist 'Dynamic dampers' added to improve its already phenomenal grip. The 'basic' CSR set an unofficial time of 1.17.4 on the BBC Top Gear test track at Dunsfold, placing it ahead of many of the world's most expensive performance cars.

  • Engines: 2.3-litre Ford Duratec tuned by Cosworth (200 bhp or 260 bhp)

Future models

Caterham announced a CSR175 model at the Tokyo Motorshow in November 2009. To celebrate the 50th anniversary of the Seven 2007 Caterham showed a concept car known as the X330 which utilised the CSR chassis but with a supercharged Template:Convert Duratec engine. Production is unconfirmed.

In the final edition of Team Lotus Notes it was announced that Caterham was developing a new model of road car that was scheduled for release in 2014.


RS Performance RST-V8 Engine

The 'Caterham Levante', built by RS Performance Engine Developments Ltd. (RS=Russell Savory), is a mostly-carbon-fibre bodied Caterham, with Kevlar seats, combined with an "over 500bhp" 2.4-litre, 40-valve supercharged V8 and a reduced body weight of Template:Convert boasts almost Template:Convert per tonne (initial announced specifications were Template:Convert and Template:Convert, but the RS website specifies "in excess of 500bhp," and Template:Convert or Template:Convert; the math may or may not achieve "over Template:Convert per tonne"). The eight cars, costing £115,000, sold out. and only eight will be produced to celebrate more than 50 years in production. Two days' of mandatory "driver training" are included in the price of the car.

Kit build

All of the 2008 model line-up is available as a 'CKD' complete kit for build by the owner, with the exception of CSR models.


Historically, engines have been supplied by Ford, specifically Ford Kent engines or Cosworth-derived race-prepared BDA/R units, enlarged to 1.7 litres and generating 150–170 bhp. In the early '90s, Caterham started using powerplants from other sources, with the least expensive models using 1.4-litre K series engines from MG Rover for the base model, and Vauxhall engines including full race versions of the 16 valve 2.0XE "red top" as fitted to 1990 Vauxhall Works Touring Cars. Rover engines span a power output of 110–250 bhp in the R500 Evolution, Vauxhall engines Template:Convert to Template:Convert in some factory built versions of the car. A Template:Convert Caterham JPE (Jonathan Palmer Evolution) briefly held the world record for production car 0–60 mph times (at 3.4 seconds) until it was bettered by the $1M McLaren F1.

The many aftermarket tuning companies for these cars have also offered the Ford Zetec, Honda Fireblade, Honda Blackbird, Suzuki Hayabusa and even the Mazda Rotary engine.

In 2001, Caterham designated MG Rover the sole engine supplier for factory-built Sevens, with Ford Zetec, Honda Fireblade, Yamaha R1 and Suzuki Hayabusa engines still available for kit assembly. The Rover engines were based on the K series and carried the 'Xpower' branding. However, the partnership evidently came to an end with the buyout of Rover by China, with the 2005 model introducing a Ford Duratec engine.

Typical powerplant output ranges from Template:Convert to over Template:Convert, depending on specifications and modifications.

The gearbox is either the classic Ford T9 five-speed or Caterham's own six-speed box. The T9 is cheap and durable, but has gear ratios meant for a much heavier car. The six-speed gearbox is expensive and had early 'teething' problems, but its ratios are considered the perfect match for the Seven. Independent companies such as Quaife do offer replacement gearkits for the T9 as well as sequential boxes for those with a racing fever and the need for a more robust transmission.

The most extreme engine/chassis combination available from the factory as of 2008 was the R500 with the Template:Convert Ford engine, bringing the car's Template:Convert from zero to Template:Convert in 2.88 seconds. The previous model also held a production car world record for zero to Template:Convert back to zero at 10.73 seconds (faster than many modern family saloons can reach 60), set in 27 April 2004.Template:Citation needed

Motor racing

Formula One


From 2012, the F1 team also owned by Tony Fernandes, known as Team Lotus in the 2011 season, races as Caterham F1 Team. The team maintained the Green and Yellow livery previously used when Team Lotus in 2011. On the 26th January 2012 the F1 team unveiled Caterham's first F1 car the CT-01 in F1 Racing Magazine.

GP2 Series


Since 2012 Caterham races in GP2 with under the guise Caterham Racing which was rebranded from Caterham Air Asia team that raced in the 2011 season. The team races under the same Green and Yellow livery as the Formula 1 team. Caterham Racing is used by the company to act as a feeder team towards developing racing drivers for the F1 team Caterham F1. Initially based in Hingham, the team has since moved to the Leafield Technical Centre alongside the F1 team in August 2012.

The Caterham Motorsport Ladder


The Caterham Motorsport Ladder is a progression through the various Caterham Cars championships, starting with the Caterham Academy, and moving through ultimately to their most prestigious European events. The championships which form the ladder are:

Caterham Academy

Caterham Academy Cars

In 1995 the Caterham Academy, a novices-only format, was introduced in the UK as the Caterham Scholarship. For £17,995 (2009 price), entrants get a modified Roadsport kit (a factory-built option is available for extra cost) with a sealed Ford Sigma engine engine and 5-speed gearbox. Having completed the ARDS (racing) licence qualification, the season then consists of a setup day, three speed events (sprints and hillclimbs), and four circuit races.

Since 2000, the popularity of the Academy has led to Caterham providing two parallel Academy championships (Group 1 & Group 2), each resulting in an Academy champion at the end of the year. Approximately 700 racing drivers have been created through the Caterham Academy.


At the Autosport International 2012 Caterham announced that it would be creating a karting series starting in 2013. It was stated that the aim of this karting series was to make it easier for people to enter motorsports by providing a cheap karting series in which they could start off.
