About Caterham

Caterham’s history is linked with the history of Lotus cars. Colin Chapman designed the Lotus seven series 1 car in 1957 which was very popular among race car enthusiasts of the time. Later the Lotus company launched the series 2, series 3 and series 4 versions of the Lotus Seven in 1960, 1968 and 1970 respectively. In 1973, Lotus took a decision to discontinue the model. At that time Graham Nearn, the founder of the Caterham Company, which was a major dealer for the Lotus cars, purchased the rights to produce the discontinued Lotus Seven model cars from Colin Chapman.


At first Caterham started producing the Series 4 which was the latest version of the Lotus seven cars. But due to less popularity than the series 3 version, Caterham switched to produce series 3 version from 1974. The caterham produced Lotus cars were called as the Lotus/Caterham 7.

The Caterham car company was started at Caterham at Surrey in UK and the offices worked there until 1987. In 1987, the administration of the company was moved to a new factory at Dartford at Kent in UK. But a Caterham south showroom was retained near the railway station which worked till February 2013. Additionally the Caterham Midlands showroom operates outside Leicester. In 2012, the caterham cars moved to a new facility which was located at Leafield. The new models of the Caterham cars are expected to be built and developed in this new facility for the future. This new facility was formerly used by Arrows F1 tem and Super Aguri F1 team. This will also accommodate the Caterham F1 team which was at first operating from Hingham Norfolk.

The company produces the Caterham seven cars for more than 55 years. The year 2007 marked the 50th anniversary of the company and the iconic sports car. In 2011, the Lotus team’s owner, Tony Fernandes, officially announced that he had purchased Caterham Company. The company was headed by Ansar Ali, who held office as the CEO of the company since 2006 to 2012. Later Graham Mc Donald, the former CFO of the company took in charge as the CEO and heads the company now.

Caterham cars:

Caterham cars are known for their light weight which is considered a special virtue of any sports car. As the Lotus seven cars were designed, Caterham seven cars are also built with aluminium sheet which is attached to a tubular steel chassis. The nosecone of the car is made of two materials which can be specified by the buyer. It can be either Glass Reinforced Plastic (GRP) or can be made of Carbon fibre. The Caterham seven cars are rear wheel drive cars and have a front mounted engine. They have a capacity to carry two persons.

The speed of the Caterham seven cars are from the sole design of light weight of the car. Some versions of the Caterham seven cars are even less than 500 kgs. The engine of the cars is not particularly powerful. Also the car compromises a lot on its safety features like roof, airbags, ABS, traction control and other safety and comfort units of a car. As there are not much safety features in the car, the weight of the car is still more reduced which gives the speedy sports car an advantage. But this reduces the everyday practicality of the car and makes it a pure race car. So the car is not preferred for family drives.

The Caterham cars continued the trend of Kit cars which was excelled by the Lotus cars. The Lotus seven cars were sold as Kit form in UK so that the tax burden is reduced as England had a higher taxation system for larger cars than the tax for self assembled cars. When the Lotus seven models were continued by Caterham, it gave the cars in Complete Knock Down (CKD) kit form. This was welcomed by driving enthusiasts. Modern kit cars of the Caterham are given as ready to assemble parts and do not needs a donor car, fabrication or any special skills, which is a major difference between Caterham cars and other kit form cars.

Caterham engines:

The earlier cars of the Lotus as well as Caterham used a Lotus Twin cam engines. Then it followed the Ford cross flow engines. During the starting era, Caterham used engines from Ford kent or Cosworth derived race- prepared BDA/R units. The first Cosworth BDRs appeared in 1983 in 1600 cc with a power of 140 bhp. Three years later, the power was increased to 150 bhp for a 1700 cc version of the same engine. In the 90s Caterham started using other sources for its engines such as the K series engine from MG Rover and Vauxhall engines. The Rover engine gives a power of 110 – 250 bhp power in the R500 evolution. Vauxhall engines give 165 bhp to 320 bhp.

The higher power range of caterham cars which are now available in the market use mostly Ford engines only. It is said that the K series engine which are found in meager numbers in the market would be eliminated totally and only an all Ford engine models would exist.

The gear box found in the Caterham cars are either a Ford T9 five speed gear box or a Caterham six speed gear box. The Ford T9 is comparatively cheap but is meant for a heavier car than the Caterham cars. The Caterham’s own six speed gear box is perfectly designed to match the Seven cars.

Caterham cars in other markets:

The Caterham seven cars are widely loved by racing enthusiasts all over the world. But as Caterham does not give attention to details like safety and emission features to maintain the reduced weight of the car, the cars are sold only on limited numbers in markets other than UK.

In The United States, Caterham cars are sold only as kit forms as they lack some safety features which are essential for cars on American roads, but which are not essential regulations for self assembled cars. The car can be assembled by the buyer or he can choose an option paying for a local dealer to assemble the car. The engine and transmission are the core units given by the Caterham company while the other components such as the frame, differential, driveshaft, suspension interior wiring and instruments are provided in kit form. In UK, the cars can also be registered under Single Vehicle Approval (SVA), when bought as a fully assembled car from Caterham.

Caterham cars in Racing:

The Caterham F1 racing team was first seen in 2012 F1 races. The team first entered the competition with the name Lotus racing under the license of the Group Lotus. When Lotus team’s parent company, the Proton, cancelled the license, Tony Fernandes acquired the name Team Lotus in 2011. Later Proton sued against Tony Fernandes and he acquired Caterham cars. The team applied to change its name formally and competed in the 2012 F1 season as the Caterham F1. The Caterham F1 maintained the same green and yellow livery used by the team Lotus in the year 2011. The first F1 car of Caterham the CT-01 was revealed in the F1 racing magazine on 26th January 2012. The team moved to the Leafield technical centre in 2012. Truli and Kovalainen were the key sport drivers in the 2011 F1 season and the team finished 10th in the constructor championship. In the 2012 Formula 1 season, Truli and Kovalainen sign the agreement to play for the same team under the name Caterham. But later it was announced that Vitaley Petrov would replace Truli and Kovalainen would team with him. In the early part of the race, caterham was found lagging but later Kovalainen made it for the Q2, eliminating Michael Schumacher in the 2012 season. At the Monaco Grand Prix Kovalainen achieved the season’s best thirteenth place. In Valencia, Kovalainen collided with Toro Rossos’ car, but managed to complete the final lap at 14th position, just behind Petrov who made the best finish of Caterham at the 13th position.  In January 2012, the team moved to the Leafield technical centre, which was the headquarters of the Arrows and super Arguri F1 teams. Caterham CT01 was the first car built to use the Kinetic Energy Recovery System (KERS). By this system, a moving vehicle’s kinetic energy can be recovered while the vehicle is braking. This recovered energy is stored in a reservoir such as a fly wheel or a battery. It is used during acceleration of the vehicle later.

In the GP2 series, Caterham competes in the name of Caterham Racing from the year 2012. In the previous year the team was called as Caterham Air Asia. The team is also owned by Tony Fernandes and retains the same green and yellow livery of the Formula 1 team. This GP2 team is used as a feeder team for the development of racing drivers for the F1 team Caterham F1. The team was initially based at Hingham and then it moved to Leafield technical centre along with the F1 team from August 2012.

Caterham racing is a competition among Caterham cars across the world, estimated to be completed in 11 countries. The Caterham motorsport ladder is the series of race events which forms a progression through various Caterham car championships. It starts with the Caterham Academy and there are various steps through the races till the most prestigious European car events.

It is actually independent from Caterham Motorsport ladder but it is run by the same members of Caterham academy. The Caterham graduate’s championship was first held in the year 1998. During the early couple of years this championship was also a multi disciplinary event with a mix of sprints, hill climbs and circuit races as in the Caterham Scholarship. But later the event was solely held for circuit races from 2000. It comprises of various classes such as classic graduate, super graduate, mega graduate and sigma graduates, using the high end sigma engine cars.

In the year 2012, Caterham announced its desire to create a karting team at 2013.
