Porsche 909 Bergspyder
The Porsche 909 "Bergspyder" was a spyder sports car designed and built by Porsche in 1968. Its purpose was to compete in hillclimbing competitions, specifically the EHCC Sports Car (Gr. P) class of the European Hillclimb Championship. It was a short-lived model, but its basic structure, technical innovations, and overall design became the basis for the successful 908/3. History Porsche had reigned champion with earlier models, the 910, 907, and 908, winning nine European Hillclimb Championship titles out of eleven years of participation. After being defeated two years in a row, Ferrari set out to develop a dedicated hillclimb car to challenge Porsche in 1967. This car was the 212 E Montagna, and was announced to compete for the 1968 European Hillclimb Championship. Despite this initial claim, Ferrari postponed its development, with the car being unveiled in 1969. Still, given the shocking news at the time of the 212's announcement, Ferdinand Piëch and his team of enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche Flat-eight Engines
German carmaker Porsche built several series of flat-eight engines of differing displacements over the course of many years. They were mainly used in Porsche's racing cars. Type 753 The first Porsche flat-eight was the Type 753. Work began on it in 1960, following the announcement of a 1.5-litre displacement limit for the 1961 Formula One (F1) season. The design of the new F1 engine was done by Hans Hönick and Hans Mezger. The 753 inherited the traditional Porsche features of a Flat engine#Boxer engine, boxer layout and air-cooling, but with the number of cylinders increased to eight. Bore and stroke were respectively, resulting in a displacement of . The oversquare dimensions kept piston speeds low, and also kept the engine narrow and as far out of the airflow on the sides of the car's tub as possible, although it was still wider than the 120° V6 and 90° V8s of the competition. The centre of the engine was a magnesium crankcase cast in two halves split vertically along the ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Piëch
Ferdinand Karl Piëch (; 17 April 1937 – 25 August 2019) was an Austrian business magnate, engineer and executive who was the chairman of the executive board (''Vorstandsvorsitzender'') of Volkswagen Group in 1993–2002 and the chairman of the supervisory board (''Aufsichtsratsvorsitzender'') of Volkswagen Group in 2002–2015. A grandson of Ferdinand Porsche, Piëch started his career at Porsche, before leaving for Audi after an agreement that no member of the Porsche or Piëch families should be involved in the day-to-day operations of the Porsche company. Piëch eventually became the head of Audi, where he is credited with evolving and growing Audi into a competitor to equal Mercedes-Benz and BMW, thanks in part to innovative designs such as the Quattro and 100. In 1993, Piëch became the chairman and CEO of Volkswagen Group, which he is credited with turning into the large conglomerate it is today; He oversaw the purchase of Lamborghini and Bentley, as well as the fo ...

Sports Prototypes
A sports prototype, sometimes referred to as simply a prototype, is a type of race car that is used in the highest-level categories of sports car racing. These purpose-built racing cars, unlike street-legal and production-based racing cars, are not intended for consumer purchase or production beyond that required to compete and win races. Prototype racing cars have competed in sports car racing since before World War II, but became the top echelon of sports cars in the 1960s as they began to replace homologated sports cars. Current ACO regulations allow most sports car series to use two forms of cars: grand tourers (GT), based on street cars, and prototypes, which are allowed a great amount of flexibility within set rule parameters. In historic racing, they are often called "sports racing cars". Sometimes, they are incorrectly referred to as "Le Mans cars", whether they are competing in the Le Mans race or not. Types of sports prototypes Since the 1960s, various championships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnesium
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. In the cosmos, magnesium is produced in large, aging stars by the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas, much of the magnesium is expelled into the interstellar medium where it ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanium
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beryllium
Beryllium is a chemical element with the symbol Be and atomic number 4. It is a steel-gray, strong, lightweight and brittle alkaline earth metal. It is a divalent element that occurs naturally only in combination with other elements to form minerals. Notable gemstones high in beryllium include beryl ( aquamarine, emerald) and chrysoberyl. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars, beryllium is depleted as it is fused into heavier elements. Beryllium constitutes about 0.0004 percent by mass of Earth's crust. The world's annual beryllium production of 220 tons is usually manufactured by extraction from the mineral beryl, a difficult process because beryllium bonds strongly to oxygen. In structural applications, the combination of high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of water) ma ...

Spaceframe
In architecture and structural engineering, a space frame or space structure ( 3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut. History Alexander Graham Bell from 1898 to 1908 developed space frames based on tetrahedral geometry. Bell's interest was primarily in using them to make rigid frames for nautical and aeronautical engineering, with the tetrahedral truss being one of his inventions. Max Mengeringhausen developed the space grid system called MERO (acronym of ''MEngeringhausen ROhrbauweise'') in 1943 in Germany, thus initiating the use of space trusses in architecture. The commonly used method, still in use has individual tubular m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula 1
Formula One (also known as Formula 1 or F1) is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The World Drivers' Championship, which became the FIA Formula One World Championship in 1981, has been one of the premier forms of racing around the world since its inaugural season in 1950. The word ''formula'' in the name refers to the set of rules to which all participants' cars must conform. A Formula One season consists of a series of races, known as ''Grands Prix'', which take place worldwide on both purpose-built circuits and closed public roads. A points system is used at Grands Prix to determine two annual World Championships: one for drivers, the other for constructors. Each driver must hold a valid Super Licence, the highest class of racing licence issued by the FIA. The races must run on tracks graded "1" (formerly "A"), the highest grade-rating issue ...

Ferrari 212 E Montagna
The Ferrari 212 E Montagna was a one-off spyder sports racing car produced by Ferrari in 1968. The car was built on a Dino 206 S chassis and used a unique 2-litre, 48-valve, flat-12 engine, a development of the 1512 1.5-litre Formula One engine. Driven by Peter Schetty, the car dominated the 1969 European Hill Climb Championship, placing first in every race it entered and setting many course records. Development history In 1964, Ferrari developed the ''Tipo'' 207 1.5- litre flat-twelve engine for its 1512 F1 car. This basic design by Mauro Forghieri was modified by Stefano Jacoponi to create the Tipo 232 2-litre engine used in the 212 E. Overall capacity of this engine was 1990.08cc, bore and stroke was 65mm X 50mm and the compression ratio was 11:1. Initially, the engine produced approximately 280-290 bhp at 11,500 rpm. Two units of the Tipo 232 motor were produced, with the first scrapped following initial development and dyno testing. The second Tipo 232 engine was inst ...
