Lotus Mk4
Lotus Mark IV was a trials car by Colin Chapman built on an Austin 7 chassis. Chapman's success at building trials cars brought another previous customer, Mike Lawson, to order a second trials car in 1952 to replace his Lotus Mark II, in which he won the Wrotham Cup. Once again Chapman chose an Austin Seven as the starting point, reinforcing the frame and installing a four- cylinder , Ford, sidevalve engine. Chapman used all the tricks he had learned in his previous cars, constructing a lightweight aluminium body with a rounded nosecone. He fitted a 3-speed transmission taken from a Ford 8 and the divided front axle as on his previous cars. Lawson won his class in the first attempt in this car, following up with others, solidifying Chapman's reputation as a designer and engineer. The success of this car, and other requests for more cars, led Chapman and Michael Allen to establish Lotus Engineering in a disused stable in Hornsey.Setright, L.J.K, "Lotus: The golden mean", ...

Colin Chapman
Anthony Colin Bruce Chapman (19 May 1928 – 16 December 1982) was an English design engineer, inventor, and builder in the automotive industry, and founder of Lotus Cars. In 1952 he founded the sports car company Lotus Cars. Chapman initially ran Lotus in his spare time, assisted by a group of enthusiasts. His knowledge of the latest aeronautical engineering techniques would prove vital towards achieving the major automotive technical advances for which he is remembered. His design philosophy focused on cars with light weight and fine handling instead of bulking up on horsepower and spring rates, which he famously summarised as "Adding power makes you faster on the straights. Subtracting weight makes you faster everywhere." Under his direction, Team Lotus won seven Formula One Constructors' titles, six Drivers' Championships, and the Indianapolis 500 in the United States, between 1962 and 1978. The production side of Lotus Cars has built tens of thousands of relati ...

Sports Car
A sports car is a car designed with an emphasis on dynamic performance, such as handling, acceleration, top speed, the thrill of driving and racing capability. Sports cars originated in Europe in the early 1900s and are currently produced by many manufacturers around the world. Definition Definitions of sports cars often relate to how the car design is optimised for dynamic performance, without any specific minimum requirements; both a Triumph Spitfire and Ferrari 488 Pista can be considered sports cars, despite vastly different levels of performance. Broader definitions of sports cars include cars "in which performance takes precedence over carrying capacity", or that emphasise the "thrill of driving" or are marketed "using the excitement of speed and the glamour of the (race)track" However, other people have more specific definitions, such as "must be a two-seater or a 2+2 seater" or a car with two seats only. In the United Kingdom, early recorded usage of the "sports car" ...

Roadster (automobile)
A roadster (also spider, spyder) is an open two-seat car with emphasis on sporting appearance or character. Initially an American term for a two-seat car with no weather protection, usage has spread internationally and has evolved to include two-seat convertibles. The roadster was also a style of racing car driven in United States Auto Club (USAC) Championship Racing, including the Indianapolis 500, in the 1950s and 1960s. This type of racing car was superseded by rear-mid-engine cars. Etymology The term "roadster" originates in the United States, where it was used in the 19th century to describe a horse suitable for travelling. By the end of the century, the definition had expanded to include bicycles and tricycles. In 1916, the United States Society of Automobile Engineers defined a roadster as: "an open car seating two or three. It may have additional seats on running boards or in rear deck." Since it has a single row of seats, the main seat for the driver and passenger w ...

Austin 7
The Austin 7 is an economy car that was produced from 1923 until 1939 in the United Kingdom by Austin. It was nicknamed the "Baby Austin" and was at that time one of the most popular cars produced for the British market and sold well abroad. Its effect on the British market was similar to that of the Model T Ford in the US, replacing most other British economy cars and cyclecars of the early 1920s. It was also licensed and copied by companies all over the world. The first BMW car, the BMW Dixi, was a licensed Austin 7. In France they were made and sold as Rosengarts, and in the United States they were built by the American Austin Car Company. In Japan, Nissan also used the 7 design as the basis for their first cars, although not under licence. This eventually led to a 1952 agreement for Nissan to build and sell Austins (which were now being made under the British Motor Corporation) in Japan under the Austin name. Many Austin 7s were rebuilt as "specials" after the ...

Lotus Mark III
Lotus Mark III was a single-seater sports car built by Colin Chapman as a 750 Racer. It was the first car to ever be called a "Lotus". In 1951, Chapman began to focus on a car for road racing, rather than trials, to compete in the 750 Motor Club formula, which used the Austin 7 as a basis. To conform to the rules, Chapman had to retain the Seven's chassis, engine, gearbox, and differential. With the assistance of Nigel and Michael Allen, he modified the car to the limits of the rules. Chapman boxed the frame rails and added 14-gauge tubular cross-members for torsional stiffness. A sleek aluminum two-seater body, which weighed only 65 lbs. (29.5 kg), was added to cut down drag, and the engine was extensively modified to produce more power. The car, for all its seeming delicacy, proved startlingly faster than the competition. It led to a demand for copies (an improved Mark IIIB (registered as ONK 408) was built for Adam Currie, for instance, was the first Lotus to b ...

Lotus Mark II
The car that came to be known as the Lotus Mark II was created in 1949, while Colin Chapman was serving with the RAF. For his second car Chapman built on the knowledge gained from building and competing in the Lotus Mark I, so he again used the widely available and inexpensive Austin 7 chassis as a starting point. He boxed in the chassis rails and replaced the cross members with stronger tubular braces. He swapped the Austin engine for a Ford engine and transmission, first from a Ford 8, then from a Ford 10, but retained the Austin 7 rear axle. To be able to use a wider tyre, Chapman adapted Ford pressed-steel wheels. He modified the engine as far as the club rules would allow. Chapman used this chassis and running gear to support a cigar-shaped body with a rounded nose. It has rudimentary cycle-type mudguards. The result was a very competitive trials car, but one also suitable for circuit racing. Chapman used the car to compete in events sponsored by the 750 Motor ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ...

Sidevalve
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1950s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though some ...

Ford 8
Ford 7Y is a car built by Ford UK from 1938 until 1939. During that time 65,098 cars were produced. The car was officially marketed as a Ford Eight, and was a rebodied and slightly larger version of the Model Y. The car was powered by a 8hp (RAC horsepower) Ford sidevalve engine. A minor facelift, unveiled in September 1939, resulted in the first Anglia. The car sported some unusual features such as openable rear windows that were located in the main body work as this was only a two-door vehicle. A rear wheel cover was available on the de-luxe models with the standard version also having a recess in the rear bodywork to accept the spare wheel, albeit not covered. The storage of the spare wheel in this manner mimics the styling of the V8 Pilot An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls.
