Rear-engine, Front-wheel-drive Layout
A rear-engine, front-wheel-drive layout is one in which the engine is between or behind the rear wheels, and drives the front wheels via a driveshaft, the complete reverse of a conventional front-engine, rear-wheel-drive vehicle layout. The earliest example of the form appeared in 1932, with the design and construction of the prototype ''Maroon Car'' by chief designer Harleigh Holmes at Coleman Motors, an established builder of Front- and All-Wheel-Drive vehicles based in Littleton, Colorado. The car had front-wheel drive and was powered by a rear-mounted V-8 engine. Only one was built and the vehicle was never placed in production. Since then, it has remained an extremely uncommon drive layout throughout automotive history, used only by a few prototypes and concept cars, such as the 1937 Howie machine gun carrier (nicknamed "belly flopper"), Buckminster Fuller's 1933 Dymaxion car, which was able to turn within its wheelbase thanks to rear-wheel steering, and the 1947 Gregory ...

Dymaxion Car Illustration
Dymaxion is a term coined by architect and inventor Buckminster Fuller and associated with much of his work—prominently his Dymaxion house and Dymaxion car. Dymaxion, a portmanteau of the words ''dynamic'', ''maximum'', and ''tension''; sums up the goal of his study, "maximum gain of advantage from minimal energy input." Description A name was needed for the display of Fuller's first architectural model, later to be known as the Dymaxion house, at the Marshall Field's department store in Chicago. To create the name, wordsmith Waldo Warren was hired by Marshall Field's and spent two days listening to Fuller, getting a feel for his idiosyncratic use of language—later playing with the syllables typical of Fuller's speech until he and Fuller agreed on the word ''Dymaxion''. Fuller used the word for many of his inventions during the decades to follow, including the Dymaxion house, the Dymaxion deployment unit, the Dymaxion car, and the Dymaxion world map. Dymaxion al ...

Flat Engine
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks; in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for engines with less than six cylinders) and V engines (for engi ...

Supercar
A supercar – also called exotic car – is a loosely defined description of street-legal, high-performance sports cars. Since the 2010s, the term hypercar has come into use for the highest performing supercars. Supercars commonly serve as the flagship model within a vehicle manufacturer's line-up of sports cars and typically feature various performance-related technology derived from motorsports. Some examples include the Ferrari 458 Italia, Lamborghini Aventador, and McLaren 720S. In the United States, muscle cars were often referred to as "supercars" during the 1960s. History Europe The Lamborghini Miura, produced from 1966–1973, is often said to be the first supercar. By the 1970s and 1980s the term was in regular use, if not precisely defined. One interpretation up until the 1990s was to use it for mid-engine two-seat cars with at least eight cylinders (but typically a V12 engine), a power output of at least and a top speed of at least . Other interpretations sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-engine, Four-wheel-drive Layout
In automotive design, an M4, or Mid-engine, Four-wheel-drive layout places the internal combustion engine in the middle of the vehicle, between both axles and drives all four road wheels. It is a type of car powertrain layout. Although the term "mid-engine" can mean the engine is placed anywhere in the car such that the centre of gravity of the engine lies between the front and rear axles, it is usually used for sports cars and racing cars where the engine is behind the passenger compartment. The motive output is then sent down a shaft to a differential in the centre of the car, which in the case of an M4 layout, distributes power to both front and rear axles. The centre differential contained within many 4 wheel drive cars is similar to the conventional differential in a 2-wheel drive car. It allows torque to be distributed to both drive axles whilst allowing them to spin at different speeds, which vastly improves the cornering of a 4-wheel drive car on surfaces with high grip ...

Intellectual Property
Intellectual property (IP) is a category of property that includes intangible creations of the human intellect. There are many types of intellectual property, and some countries recognize more than others. The best-known types are patents, copyrights, trademarks, and trade secrets. The modern concept of intellectual property developed in England in the 17th and 18th centuries. The term "intellectual property" began to be used in the 19th century, though it was not until the late 20th century that intellectual property became commonplace in the majority of the world's legal systems."property as a common descriptor of the field probably traces to the foundation of the World Intellectual Property Organization (WIPO) by the United Nations." in Mark A. Lemley''Property, Intellectual Property, and Free Riding'', Texas Law Review, 2005, Vol. 83:1031, page 1033, footnote 4. The main purpose of intellectual property law is to encourage the creation of a wide variety of intellectual goo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weight function, weighted relative position (vector), position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for wikt:hollow, hollow or open-shaped object ...

Noise, Vibration, And Harshness
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical tools that can provide results reflecting human subjective impressions. The latter tools belong to the field psychoacoustics. Interior NVH deals with noise and vibration experienced by the occupants of the cabin, while exterior NVH is largely concerned with the noise radiated by the vehicle, and includes drive-by noise testing. NVH is mostly engineering, but often objective measurements fail to predict or correlate well with the subjective impression on human observers. For example, although the ear's response at moderate noise levels is approximated by A-weighting, two different noises with the same A-weighted level are not necessarily eq ...

Crumple Zone
Crumple zones, crush zones, or crash zones are a structural safety feature used in vehicles, mainly in automobiles, to increase the time over which a change in velocity (and consequently momentum) occurs from the impact during a collision by a controlled deformation (engineering), deformation; in recent years, it is also incorporated into trains and railcars. Crumple zones are designed to increase the time over which the total force from the change in momentum is applied to an occupant, as the average force applied to the occupants is inversely related to the time over which it is applied. The physics involved can be expressed by the equation: :F_\text\Delta t = m\Delta v where F is the force, t is the time, m is the mass, and v is the velocity of the body. In SI units, force is measured in Newton (unit), Newtons, time in seconds, mass in kilograms, velocity in metres per second, and the resulting Impulse (physics), impulse is measured in newton seconds (N⋅s).

Volkswagen Type 3
The Volkswagen Type 3 is a compact car manufactured and marketed by Volkswagen from 1961-1973. Introduced at the 1961 Frankfurt Motor Show, ''Internationale Automobil-Ausstellung (IAA)'', the Type 3 was marketed as the Volkswagen 1500 and later as the Volkswagen 1600, in three body styles: two-door Notchback, Fastback, and Station Wagon, the latter marketed as the 'Squareback' in the United States. The Type 3 diversified Volkswagen's product range beyond the existing models – the Type 1 Beetles, Type 14 Karmann Ghia, Type 2 vans and pickups – while retaining Volkswagen's hallmark engineering features: the air-cooled rear-engine, rear-wheel drive train, body-on chassis construction with a backbone chassis integrated into the car's floorpan), as well as torsion bar front and rear suspension. Despite using the Beetle's wheelbase, the Type 3 was conceived as a larger car, offering a larger engine and increased cargo and passenger volume — the latter from ...

Transaxle
A transaxle is a single mechanical device which combines the functions of an automobile's transmission, axle, and differential into one integrated assembly. It can be produced in both manual and automatic versions. Engine and drive at the same end Transaxles are nearly universal in all automobile configurations that have the engine placed at the same end of the car as the driven wheels: the front-engine/front-wheel-drive; rear-engine/rear-wheel-drive; and mid-engine/rear-wheel-drive arrangements. Many mid- and rear-engined vehicles use a transverse engine and transaxle, similar to a front-wheel-drive unit. Others use a longitudinal engine and transaxle like Ferrari's 1989 Mondial t which used a "T" arrangement with a longitudinal engine connected to a transverse transaxle. Front-wheel-drive versions of modern Audis, from the A4 upwards, along with their related marques from the Volkswagen Group (which share the same automobile layout) also use a similar layout, but w ...
