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 be so ...

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 ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
750 Motor Club
750 Motor Club is a motor racing club in the UK. It was founded in 1939 to promote the sporting use of the Austin 7. '750' refers to the near-750cc Austin 7 engine. It later led to racing and the 750 Formula where specials are raced. Famous members include Colin Chapman, Eric Broadley, Adrian Reynard, Arthur Mallock, Derek Bennett, Tony Southgate, Brian Hart, Gordon Murray, Jem Marsh, Frank Costin and Mike Pilbeam. These engineers and designers produced the first Lotus, Lola, Chevron, Speedex, Marcos, Pilbeam and other sports and racing cars between the 1940s and 1960s. The 750MC has continued to promote competitive, low-cost racing for enthusiasts, with a range of championships for production and racing sports cars, saloons and single-seaters. Series and Championships 750 Formula Championship The world's oldest sports prototype formula, with all cars using the 1.1 litre Fiat FIRE engine.

Road Racing
Road racing is a form of motorsport racing held on a paved road surface. The races can be held either on a closed circuit or on a street circuit utilizing temporarily closed public roads. Originally, road races were held almost entirely on public roads. However, public safety concerns eventually led to most races being held on purpose-built racing circuits. Road racing's origins were centered in Western Europe and Great Britain as motor vehicles became more common in the early 20th century. After the Second World War, automobile road races were organized into a series called the Formula One world championship sanctioned by the Fédération Internationale de l'Automobile (FIA), while motorcycle road races were organized into the Grand Prix motorcycle racing series and sanctioned by the Fédération Internationale de Motocyclisme (FIM). The success and popularity of road racing has seen the sport spread across the globe with Grand Prix road races having been held on six continent ...

Classic Trials
Classic trials, or colloquially mud plugging, is one of the oldest forms of rallying or off-road motor sports, dating from the beginning of the 20th century. Originally, the challenge was just to complete a long (challenging) road course. All three Motor Cycling Club long distance trials in the UK – the Land's End, the Exeter and the Edinburgh Edinburgh ( ; gd, Dùn Èideann ) is the capital city of Scotland and one of its 32 Council areas of Scotland, council areas. Historically part of the county of Midlothian (interchangeably Edinburghshire before 1921), it is located in Lothian ... – date from that time, and are still held today. As vehicles became more reliable, the events became easier and the concept of ''observed non-stop'' sections was introduced. On these, the car or motorcycle is stopped at the foot of a hill and has to make a non-stop ascent. On a classic trial today, there will typically be around fifteen of such "observed sections", mixed with betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gearbox
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel ma ...

Aerodynamic Drag
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chapman built the body utilizing a composite made of thin aluminum bonded to plywood. He modified the rear suspension to give better handling and the engine to give more power. His approach to automobile construction using sound engineering principles and ingenious chassis design set the stage for many more revolutionary designs to follow. Although the original Mark I has been lost to history after being bought by a mysterious buyer in 1950, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornsey
Hornsey is a district of north London, England in the London Borough of Haringey. It is an inner-suburban, for the most part residential, area centred north of Charing Cross. It adjoins green spaces Queen's Wood and Alexandra Park to the north. Known locally as Hornsey Village (to avoid confusion with the original borough of Hornsey) it is London's oldest recorded village, first recorded in 1202, according to the Place Names of Middlesex. Locale Hornsey is relatively old, being originally a village that grew up along Hornsey High Street, at the eastern end of which is the churchyard and tower of the formeSt Mary's parish church which was first mentioned i1291 At the western end is Priory Park. This was the administrative centre of the historically broad parish. North of Hornsey High Street, and immediately to its south, some of the area is public sector housing, surrounded by the late Victorian terraces developed by builders such as John Farrer.
