Porsche 911
The Porsche 911 model series (pronounced ''Nine Eleven'' or in ) is a family of German two-door, high performance Rear-engine design, rear-engine sports cars, introduced in September 1964 by Porsche, Porsche AG of Stuttgart, Germany. Now in its eighth generation, all 911s have a rear-mounted flat-six engine, and usually 2+2 (car body style), 2+2 seating, except for special 2-seater variants. Originally, 911s had Air-cooled engine, air-cooled engines, and torsion bar suspension, but the 911 has been continuously enhanced, and evolved across generations. Though the 911 core concept has remained largely unchanged,Corlett, p. 12 water-cooled engines were introduced with the Porsche 996, 996 series in 1998, and front and rear suspension have been replaced by Porsche-specific MacPherson strut, MacPherson suspension up front, and independent multi-link rear suspension. The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most succes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Car
A sports car is a type of automobile that is designed with an emphasis on dynamic performance, such as Automobile handling, handling, acceleration, top speed, the thrill of driving, and Auto racing, racing capability. Sports cars originated in Europe in the early 1910s 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.

Ferdinand Alexander Porsche
Ferdinand Alexander Porsche (11 December 1935 – 5 April 2012), also known by the nickname "Butzi", was a German-Austrian designer whose best known product was the first Porsche 911. He was the son of Ferry Porsche, and the grandson of Ferdinand Porsche. While his grandfather and father were both engineers, he was more involved in working out the appearance of a product. He never thought of himself as an artist or designer, but more as a technically talented craftsman in shaping. Education After attending the Waldorf School in Stuttgart he began studying industrial design at the Ulm School of Design. After a year he was dismissed by the examination board, because his talent was doubted. In 1957 he started practical training at the body design department of the family-owned sports car company under design director Erwin Komenda. Porsche 911 When it came to the designworks of the coachwork for the company's most successful car so far, the Porsche 911, Ferdinand Alexande ...

Porsche 959
The Porsche 959 is a sports car manufactured by German automobile manufacturer Porsche from 1986 to 1993, first as a Group B rally car and later as a road legal production car designed to satisfy FIA homologation regulations requiring at least 200 units be produced. The twin-turbocharged 959 was the world's fastest street-legal production car when introduced, achieving a top speed of , with some variants even capable of achieving . Combining race-car performance with luxury-sedan comfort and everyday drivability in dry, wet and snowy conditions, it was considered the most technologically advanced road car of its time. After the successful introduction of all-wheel drive on more rally-specific cars like the Audi Quattro, it was one of the first pure high-performance sports-cars with all-wheel drive, providing the basis for Porsche's first all-wheel drive 911 Carrera 4 model. Its performance convinced Porsche executives to make all-wheel drive standard on all turbocharged versi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torsion Bar Suspension
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M46/M47/M48 Patton, M60 and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps. Air-cooled engines are widely seen in applications where weight or simplicity is the primary goal. Their simplicity makes them suited for uses in small applications like chainsaws and lawn mowers, as well as small generators and similar roles. These qualities also make them highly suitable for aviation use, where they are widely used in general aviation aircraft and as auxiliary power units on larger aircraft. Their simplicity, in particular, also makes them common on motorcycles. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head. A fl ...

2+2 (car Body Style)
A 2+2 (also 2-plus-2) is a car-body style that has a seat each for the driver and front passenger, and two rear seats. The latter may be individual "bucket" seats, fold-downs, or a full-width "bucketed" bench seat, but always with less leg room than either the front or a standard 2-door car. The style is different from 4- or 5- seat automobiles having normal-size rear seats, with second-row 2+2 seating typically only suitable for children or occasional use. Definition By standard definition, all cars in the 2+2 category have two front seats and two rear seats. Other common characteristics for 2+2 cars include relatively little room for the rear passengers and a "streamlined" body with two doors. While 2+2 seating is most commonly associated with coupés, especially those which strongly favour front passenger seating such as sports cars and gran turismos, certain convertibles with "auxiliary"-type rear seats may also be regarded as 2+2s. Some vehicles (such as the TVR C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat-six Engine
A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same time. An alternative configuration for flat engines is a 180-degree V engine, where both cylinders move to the right then the left at the same time. The advantages of the flat-six layout are good engine balance (for reduced vibration), a low center of gravity, short length (compared with an inline-six engine) and being well suited to air-cooling. The disadvantages are a large width (which can limit the maximum steering angle when used in a front-engined car), a large intake manifold being required when a central carburetor is used, and duplication of the inlet and outlet connections for water-cooled engines. The first production flat-six engine was in the 1904 '' Wilson-Pilcher 18/24 HP'' c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche 356
The Porsche 356 is a rear-engine sports car, and the first ever production Porsche model. The 356 is a lightweight and nimble-handling, rear-engine, rear-wheel drive, two-door available both in hardtop coupé and open configurations. Engineering innovations continued during the years of manufacture, contributing to its motorsports success and popularity. Production started in 1948 at Gmünd, Carinthia, Gmünd, Austria, where Porsche built approximately 50 cars. In 1950 the factory relocated to Zuffenhausen, Germany, and general production of the 356 continued until April 1965, well after the replacement model Porsche 911, 911 made its September 1964 debut. Of the 76,000 originally produced, approximately half survive. It was first produced by Austrian company Porsche Konstruktionen GesmbH (1948–1949), and then by German company Porsche, Dr. Ing. h. c. F. Porsche GmbH (1950–1965). It was Porsche's first production automobile. Earlier cars designed by the Austrian company inc ...

All-wheel Drive
An all-wheel drive vehicle (AWD vehicle) is one with a powertrain capable of providing power to all its wheels, whether full-time or on-demand. Types The most common forms of all-wheel drive are: ;1x1 : All unicycles Reflects one axle with one wheel capable of being powered. ; 2x2 : Some motorcycles and bikes Reflects two axles with one wheel on each capable of being powered. ; 4×4 (also, four-wheel drive or 4WD): Reflects two axles with both wheels on each capable of being powered. ; 6×6 (also, six-wheel drive or 6WD): Reflects three axles with both wheels on each capable of being powered. ; 8×8 (also, eight-wheel drive or 8WD): Reflects four axles with both wheels on each capable of being powered. Vehicles may be either part-time all-wheel drive or full-time: ;On-demand or Part-time: One axle is permanently connected to the drive, the other is connected as needed ;Full-time or Permanent: All axles are permanently connected, with or without a differential. ;Independ ...

Rear-wheel Drive
Rear-wheel drive (RWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the rear wheels only. Until the late 20th century, rear-wheel drive was the most common configuration for cars. Most rear-wheel drive vehicles feature a longitudinally-mounted engine at the front of the car. Layout The most common layout for a rear-wheel drive car is with the engine and transmission at the front of the car, mounted longitudinally. Other layouts of rear-wheel drive cars include front-mid engine, rear-mid engine, and rear-engine. Some manufacturers, such as Alfa Romeo, Lancia, Porsche (944, 924, 928) and Chevrolet (C5, C6, and C7 Corvettes), place the engine at the front of the car and the transmission at the rear of the car, in order to provide a more balanced weight distribution. This configuration is often referred to as a transaxle since the transmission and axle are one unit. History 1890s to 1960s Many of the cars built in the 19th cent ...

Rear-engine Design
In automobile design, a rear-engine design layout places the engine at the rear of the vehicle. The center of gravity of the engine itself is behind the rear axle. This is not to be confused with the center of gravity of the whole vehicle, as an imbalance of such proportions would make it impossible to keep the front wheels on the ground. Rear-engined vehicles almost always have a rear-wheel drive car layout, but some are four wheel drive. This layout has the following features: *Packaging: since there is no need for a transmission tunnel, the floor can be flat. *Rear traction: having the engine located over the driven wheels increases downward pressure, which is helpful for grip on loose surfaces, although can be prone to oversteer. *Simplicity of manufacture: the engine is near the driven wheels, and the transmission can be merged with the differential to save space. This layout was once popular in small, inexpensive cars and light commercial vehicles. Today most car makers have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
