Caterham Cars
Caterham Cars is a British manufacturer of specialist lightweight sports cars established in Caterham, England, with their headquarters in Dartford, England. Their current model, the Caterham 7 (or Seven), originally launched in 1973, is a direct evolution of the Series 3 Lotus Seven designed by Colin Chapman. 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 was scheduled for release in 2013. On 27 April 2011, Team Lotus owner Tony Fernandes announced that he had purchased Caterham. On 2 April 2021, news was leaked that Caterham Cars was acquired outright on 31 March 2021 by VT Holdings, Japanese importer for the Caterham Seven since 2009. As well as being a Caterham importer, VT also imports Lotus cars and Royal Enfield motorcycles into Japan. History Lotus origins Colin Ch ...

Ferrari F50
The Ferrari F50 (Type F130) is a mid-engine sports car manufactured by Italian automobile manufacturer Ferrari from 1995 until 1997. Introduced in 1995, the car is a two-door, two seat targa top. The car is powered by a 4.7 L naturally aspirated '' Tipo F130B'' 60-valve V12 engine that was developed from the 3.5 L V12 used in the 1990 Ferrari 641 Formula One car. The car's design is an evolution of the 1989 Ferrari Mythos concept car. A total of 349 cars were made, with the last car rolling off the production line in July 1997. The F50's engine predated the car; it was used in the Ferrari 333 SP for the American IMSA GT Championship in 1994, allowing it to become eligible for the stock engine World Sports Car category. Racing Following the motorsport theme of the Ferrari F40 LM, Ferrari developed the F50 based F50 GT in collaboration with its racing partners Dallara and Michelotto to compete in GT1-class racing. Notable changes made to the car include a fix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Dion Tube
De Dion rear axle A de Dion tube is a form of non-independent automobile suspension. It is a considerable improvement over the swing axle, Hotchkiss drive, or live axle. Because it plays no part in transmitting power to the drive wheels, it is sometimes called a "dead axle".Setright, p.515. A de Dion suspension uses a universal joint at both the wheel hubs and differential, and uses a solid tubular beam to hold the opposite wheels in parallel. Unlike an anti-roll bar, a de Dion tube is not directly connected to the chassis nor is it intended to flex. In suspension geometry it is a beam axle suspension. History The de Dion tube was named after Comte Jules-Albert de Dion, founder of French automobile manufacturer De Dion-Bouton. The tube, however, was invented around 1894 by co-founder Charles Trépardoux for use on the company's steam tricycles. G.N. Georgano, p. 27.

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier than air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simu ...

Heel-and-toe Shifting
Heel-and-toe shifting is an advanced driving technique used mostly in performance driving with a manual gearbox, although some drivers use it on the road in everyday conditions in the interest of effectiveness. It involves operating the throttle and brake pedals simultaneously with the right foot, while facilitating normal activation of the clutch with the left foot. It is used when braking and downshifting simultaneously (prior to entering a turn), and allows the driver to "blip" the throttle to raise the engine speed and smoothly engage the lower gear. (See synchronized transmission.) Usage Heel-and-toe shifting is used before entry into a turn while a vehicle is under braking, preparing the transmission to be in the optimal range of rpm to accelerate out of the turn. One benefit of downshifting before entering a turn is to eliminate the jolt to the drivetrain, or any other unwanted dynamics. The jolt will not upset the vehicle as badly when going in a straight line, but the sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

Lift (force)
A fluid flowing around an object exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to counter the force of gravity, but it can act in any direction at right angles to the flow. If the surrounding fluid is air, the force is called an aerodynamic force. In water or any other liquid, it is called a hydrodynamic force. Dynamic lift is distinguished from other kinds of lift in fluids. Aerostatic lift or buoyancy, in which an internal fluid is lighter than the surrounding fluid, does not require movement and is used by balloons, blimps, dirigibles, boats, and submarines. Planing lift, in which only the lower portion of the body is immersed in a liquid flow, is used by motorboats, surfboards, windsurfers, sailboats, and water-skis. Overview A fluid flowing arou ...

Car And Driver
''Car and Driver'' (''CD'' or ''C/D'') is an American automotive enthusiast magazine. In 2006 its total circulation was 1.23 million. It is owned by Hearst Magazines, who purchased prior owner Hachette Filipacchi Media U.S. in 2011. It was founded as ''Sports Cars Illustrated.'' The magazine is based in Ann Arbor, Michigan. History ''Car and Driver'' was founded as ''Sports Cars Illustrated'' in 1955. In its early years, the magazine focused primarily on small, imported sports cars. In 1961, editor Karl Ludvigsen renamed the magazine ''Car and Driver'' to show a more general automotive focus. ''Car and Driver'' once featured Bruce McCall, Jean Shepherd, and Brock Yates as columnists, and P. J. O'Rourke as a frequent contributor. Former editors include William Jeanes and David E. Davis, Jr., the latter of whom led some employees to defect in 1985 to create ''Automobile''. Rather than electing a Car of the Year, ''Car and Driver'' publishes its top ten picks each year ...

Short Ton
The short ton (symbol tn) is a measurement unit equal to . It is commonly used in the United States, where it is known simply as a ton, although the term is ambiguous, the single word being variously used for short, long, and metric ton. The various tons are defined as units of mass.Butcher, Crown and Gentry, NIST Special Publication 1038, The International System of Units (SI) – Conversion Factors for General Use, 2006 They are sometimes used as units of weight, the force exerted by a mass at standard gravity (e.g., short ton-force). One short ton exerts a weight at one standard gravity of 2,000 pound-force (lbf). United States In the United States, a short ton is usually known simply as a "ton", without distinguishing it from the tonne (), known there as the "metric ton", or the long ton also known as the "imperial ton" (). There are, however, some U.S. applications where unspecified ''tons'' normally mean long tons (for example, naval ships) or metric tons (world grain ...
