Weber is an Italian company which produced carburetors, it is owned by Magneti Marelli Powertrain S. p. A. which is in turn part of the Fiat Group. Carburetor production in Italy ended in 1992, although Weber carburetor production was shifted to Madrid, edoardo Weber began his automotive career working for Fiat, first at their Turin plant and at a dealership in Bologna. After the war, with prices high, he reached a certain success in selling conversion kits for running trucks on kerosene instead. The company was established as Fabbrica Italiana Carburatori Weber in 1923 when Weber produced carburetors as part of a kit for Fiats. Weber pioneered the use of two-stage twin barrel carburetors, with two venturis of different sizes, the one for low speed running and the larger one optimised for high speed use. In the 1930s Weber began producing twin-barrel carburetors for motor racing where two barrels of the size were used. These were arranged so that each cylinder of the engine has its own carburetor barrel and these carburetors found use in Maserati and Alfa Romeo racing cars.
Twin updraught Webers fed superchargers on the 1938 Alfa Romeo 8C competition vehicles, after Webers death in 1945, Fiat finally assumed control of the company in 1952. In 1986, Fiat took control of Webers competitor Solex and this was reorganized as Magneti Marelli Powertrain S. p. A. in 2001. Genuine Weber carburetors were produced in Bologna, Italy up until 1992, when production was transferred to Madrid, Weber Carburetors are sold for both street and off-road use, with the twin choke sidedraught DCOE being the most common one. They are sold in what is referred to as a Weber Conversion kit, in modern times, fuel injection has replaced carburetors in both production cars and most modern motor racing, although Weber carburetors are still used extensively in classic and historic racing. They are supplied as high quality replacements for problematic OEM carburetors, Weber fuel system components are distributed by Magneti Marelli, Webcon UK Ltd. and, in North America, by several organizations, including Worldpac, marketing under the Redline name.
Other suppliers include Overseas Distributing and Pierce Manifolds, Weber carburetors are marked with a model code on the mounting flange, the body, or on the cover of the float-chamber. This begins with a number which originally indicated the diameter of the throttle bore, after the letters there will be a further number, which may be followed by a letter, e. g. 4B, 13A, these indicate the series. The full designation might be 40 DCOE29,45 DCOE9, etc
Internal combustion engine
An internal combustion engine is a heat engine where the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine, the force is applied typically to pistons, turbine blades, rotor or a nozzle. This force moves the component over a distance, transforming chemical energy into mechanical energy. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1859, firearms are a form of internal combustion engine. Working fluids can be air, hot water, pressurized water or even liquid sodium, ICEs are usually powered by energy-dense fuels such as gasoline or diesel, liquids derived from fossil fuels. While there are many applications, most ICEs are used in mobile applications and are the dominant power supply for vehicles such as cars, aircraft.
Typically an ICE is fed with fossil fuels like natural gas or petroleum products such as gasoline, there is a growing usage of renewable fuels like biodiesel for compression ignition engines and bioethanol or methanol for spark ignition engines. Hydrogen is sometimes used, and can be made from fossil fuels or renewable energy. Various scientists and engineers contributed to the development of internal combustion engines, in 1791, John Barber developed a turbine. In 1794 Thomas Mead patented a gas engine, in 1794 Robert Street patented an internal combustion engine, which was the first to use liquid fuel, and built an engine around that time. In 1798, John Stevens built the first American internal combustion engine, in 1807, Swiss engineer François Isaac de Rivaz built an internal combustion engine ignited by electric spark. In 1823, Samuel Brown patented the first internal combustion engine to be applied industrially, in 1860, Belgian Jean Joseph Etienne Lenoir produced a gas-fired internal combustion engine.
In 1864, Nikolaus Otto patented the first atmospheric gas engine, in 1872, American George Brayton invented the first commercial liquid-fuelled internal combustion engine. In 1876, Nikolaus Otto, working with Gottlieb Daimler and Wilhelm Maybach, patented the compressed charge, in 1879, Karl Benz patented a reliable two-stroke gas engine. In 1892, Rudolf Diesel developed the first compressed charge, compression ignition engine, in 1926, Robert Goddard launched the first liquid-fueled rocket. In 1939, the Heinkel He 178 became the worlds first jet aircraft, at one time, the word engine meant any piece of machinery — a sense that persists in expressions such as siege engine. A motor is any machine that produces mechanical power, electric motors are not referred to as Engines, combustion engines are often referred to as motors. In boating an internal combustion engine that is installed in the hull is referred to as an engine, reciprocating piston engines are by far the most common power source for land and water vehicles, including automobiles, ships and to a lesser extent, locomotives
Automotive design is the profession involved in the development of the appearance, and to some extent the ergonomics, of motor vehicles or more specifically road vehicles. This most commonly refers to automobiles but refers to motorcycles, buses, the functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines included within automotive engineering. Automotive design in context is primarily concerned with developing the visual appearance or aesthetics of the vehicle. Automotive design is practiced by designers who usually have an art background, the task of the design team is usually split into three main aspects, exterior design, interior design, and color and trim design. Graphic design is an aspect of design, this is generally shared amongst the design team as the lead designer sees fit. Design focuses not only on the outer shape of automobile parts. The aesthetic value will need to correspond to ergonomic functionality and utility features as well, though not all the new vehicular gadgets are to be designated as factory standard items, some of them may be integral to determining the future course of any specific vehicular models.
The stylist responsible for the design of the exterior of the vehicle develops the proportions, Exterior design is first done by a series of digital or manual drawings. Progressively, drawings that are more detailed are executed and approved by appropriate layers of management, Clay and or digital models are developed from, and along with the drawings. The data from these models are used to create a full sized mock-up of the final design. With three- and five-axis CNC milling machines, the model is first designed in a computer program and carved using the machine. Even in times of high-class 3d software and virtual models on power walls, here the emphasis is on ergonomics and the comfort of the passengers. The procedure here is the same as with exterior design, the color and trim designer is responsible for the research and development of all interior and exterior colors and materials used on a vehicle. These include paints, fabric designs, grains, headliner, wood trim, contrast and pattern must be carefully combined to give the vehicle a unique interior environment experience.
Designers work closely with the exterior and interior designers, designers draw inspiration from other design disciplines such as, industrial design, home furnishing and sometimes product design. Specific research is done into global trends to design for two to three model years in the future. Trend boards are created from research in order to keep track of design influences as they relate to the automotive industry. The designer uses this information to develop themes and concepts that are further refined and tested on the vehicle models
A coachbuilder is a manufacturer of bodies for automobiles or a manufacturer of complete horse-drawn vehicles. Coachwork is the body of a vehicle, a horse-drawn coach or carriage, or, by extension. The term is reserved for bodies built on a separate chassis. With reference to motor vehicles, auto body is the term in North American English. Coachbuilders are, carrossiers in French, carrozzeria in Italian, karosseriebauer in German, a British trade association the Worshipful Company of Coachmakers and Coach Harness Makers, was incorporated in 1630. Some British coachmaking firms operating in the 20th century were established even earlier, rippon was active in the time of Queen Elizabeth I, Barker founded in 1710 by an officer in Queen Annes Guards, Brewster a relative newcomer, formed in 1810. This chassis would be delivered by the manufacturer to the coachbuilder of the buyers choice, the chassis would be a rolling chassis which included the chassis frame, brakes, complete steering system including the wheel, radiator and dashboard.
The manufacturer delivered the chassis with lighting system, spare wheel and rear mudguards, the very easily damaged honeycomb radiator and protected by a shell, became the main visual element identifying the chassis brand. The manufacturer retained an element of control over bodies, bodies not approved by the chassis manufacturer would lose the chassis manufacturers chassis warranties. Until the second World War it would not have been unusual to order the most popular cars as only a chassis and have a local coachbuilder put a body on it for you, the Austin 7s of the 1920s and 1930s were favourite subjects. For example, Fisher Body built all of Cadillacs closed bodies in the 1910s, though automobile manufacturers brought body building skills in-house, the practice of bespoke or custom coachbuilding remained in favour among the wealthy, who continued the habit of centuries past. All ultra-luxury vehicles sold as chassis only, for instance, when Duesenberg introduced their Model J, it was offered as chassis only, for $8,500.
Other examples include the Bugatti Type 57, Cadillac V-16, Ferrari 250, Isotta Fraschini Tipo 8, delahaye had no in-house coachworks, so all its chassis were bodied by independents, who created some of their most attractive designs on the Type 135. Most of the Delahayes were bodied by Chapron, Franay, Figoni & Falaschi, the advent of unibody construction, where the car body is unified with, and structurally integral to the chassis, made custom coachbuilding practically impossible.

Belgium, officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany and the North Sea. It is a small, densely populated country which covers an area of 30,528 square kilometres and has a population of about 11 million people. Additionally, there is a group of German-speakers who live in the East Cantons located around the High Fens area. Historically, the Netherlands and Luxembourg were known as the Low Countries, the region was called Belgica in Latin, after the Roman province of Gallia Belgica. From the end of the Middle Ages until the 17th century, Belgium is a federal constitutional monarchy with a parliamentary system of governance. It is divided into three regions and three communities, that exist next to each other and its two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region is a bilingual enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia, Belgiums linguistic diversity and related political conflicts are reflected in its political history and complex system of governance, made up of six different governments.
Upon its independence, declared in 1830, Belgium participated in the Industrial Revolution and, during the course of the 20th century, possessed a number of colonies in Africa. This continuing antagonism has led to several far-reaching reforms, resulting in a transition from a unitary to a federal arrangement during the period from 1970 to 1993. Belgium is a member of the Eurozone, NATO, OECD and WTO. Its capital, hosts several of the EUs official seats as well as the headquarters of major international organizations such as NATO. Belgium is a part of the Schengen Area, Belgium is a developed country, with an advanced high-income economy and is categorized as very high in the Human Development Index. A gradual immigration by Germanic Frankish tribes during the 5th century brought the area under the rule of the Merovingian kings, a gradual shift of power during the 8th century led the kingdom of the Franks to evolve into the Carolingian Empire. Many of these fiefdoms were united in the Burgundian Netherlands of the 14th and 15th centuries, the Eighty Years War divided the Low Countries into the northern United Provinces and the Southern Netherlands.
The latter were ruled successively by the Spanish and the Austrian Habsburgs and this was the theatre of most Franco-Spanish and Franco-Austrian wars during the 17th and 18th centuries. The reunification of the Low Countries as the United Kingdom of the Netherlands occurred at the dissolution of the First French Empire in 1815, although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 and for women in 1949. The main political parties of the 19th century were the Catholic Party, French was originally the single official language adopted by the nobility and the bourgeoisie
A Kammback is a car body style that derives from the research of the German aerodynamicist Wunibald Kamm in the 1930s. The design calls for a body with smooth contours that continues to a tail that is cut off. This shape reduces the drag of the vehicle, in Europe the design is generally known as a Kamm tail or K-tail. Paul Jaray experimented and developed streamlined car body work in the 1920s and his innovative body design featuring a low-profile teardrop shape with a long tail minimized the air resistance of passenger cars. Better highway systems being built in the 1930s called for higher automobile cruising and top speeds, wind tunnel tests showed that a true tear-drop shaped body offered only a slight improvement in efficiency to the Chrysler Airflow design. In 1935, Georg Hans Madelung, a German engineer, professor and he worked on an aerodynamic design for a bus, and Koenig-Fachsenfeld patented the idea. In addition to aerodynamic efficiency, Wunibald Kamm emphasized vehicle stability in his design and he proved mathematically and empirically the effectiveness of the design.
The Kamm-back, or K-form, was a body with a smoothly contoured front that continues to a vertical flat surface in the rear. The earliest use of Kamm to describe a body incorporating this design was the prototype 1940 Kamm Coupe based on a BMW328 chassis. The earliest mass-produced cars that used Kammback principles were the 1949–1951 Nash Airflyte in the U. S. and this is called the Kamm effect. There is controversy about the proportions of a true Kamm tail, thus a minivan is not a Kammback, and neither are numerous cars that have truncated tails. Automakers’ use of the term Kammback has diminished as Kamms principles have become more assimilated into modern car design. The 1981–1982 compact two-door hatchback version of the AMC Eagle was named a Kammback and it retained the mini-wagon look of the AMC Gremlin, but with much larger quarter glass, and rear window that derived from the AMC Spirits two-door sedan body style. e. The AMC AMX-GT and Pontiac Firebird–based Type K concept cars, - an explicitly Kamm-influenced design which informed the Citroën CX and Rover SD1 Ziemnowicz, Christopher.

Goodwood Festival of Speed
In the early years of the Festival, tens of thousands attended over the weekend, it currently attracts crowds of around 100,000 on each of the three days it is now held. A record crowd of 158,000 attended in 2003, before an advance-ticket-only admission policy came into force, attendance is now capped at 150,000. The Goodwood Festival of Speed was founded in 1993 by Lord March in order to bring racing back to the Goodwood estate — a location steeped in British motor racing history. Shortly after taking over the estate in the early 1990s, Lord March wanted to bring motor racing to Goodwood Circuit. Therefore, he hosted it on his own grounds. After the first events date clash, Lord March would ensure that the event would never be allowed to clash with either Le Mans or Formula One races, in 1994, Saturday was added, making it a weekend event. In 1996, Friday was added, making it a three-day event, in 2010, the Moving Motor Show was added on the Thursday. Visitors are free to walk around several paddocks where the cars and drivers can be seen at close quarters.
The atmosphere of the Festival of Speed, when compared to the separation of fans from drivers and machines common to most top end motor sport events, the track has an elevation change of 92.7 metres, for an average gradient of 4. 9%. The record time for the hillclimb was set in 1999 when Nick Heidfeld drove a McLaren MP4/13 Formula One car up the hill in 41.6 seconds. For safety reasons Formula One cars are no longer allowed to do official timed runs, in 2006 Heikki Kovalainen completed the course in a Renault R25 F1 car and was unofficially timed below 40 seconds. In 2016, to commemorate the 40 year anniversary of James Hunt winning the F1 World Championship, from 2000 to 2004 this was a downhill race for gravity-powered cars. Starting from just below the hill-climb finish line, to a line in front of the house. It included entries from Cosworth and other top companies, with some famous riders/drivers piloting them, including Barry Sheene. Despite an official cap on the cost of cars, the costs were becoming too high.
From 2005 to present there has been an area for the rally cars at the top of the hill. Initially, in 2005, the track through the forest was widened, and the cars ran down through the forest, turned on the tarmac section just outside the wood. This meant that the cars could only run one-at-a-time, in 2006, a full forest stage was introduced, designed by Hannu Mikkola this was a complete circuit, with a separate start and finish line at the top of the wood
Bizzarrini S. p. A. was an Italian automotive manufacturer in the 1960s founded by former Alfa Romeo, Ferrari and ISO engineer, Giotto Bizzarrini. The company built a number of highly developed and advanced sport. Notable models include the 5300 GT Strada and the P538S, the name was changed to Bizzarrini S. p. A. in 1966. The Bizzarrini marque has been revived with a number of cars in the 2000s. Giotto Bizzarrini was born in Livorno, Italy in 1926 and his father was a rich landowner who came from a family with strong roots in Tuscany and the city of Livorno. Bizzarrini graduated as an engineer in the University of Pisa in 1953 and he taught briefly before joining Alfa Romeo in 1954. He worked for Alfa Romeo from 1954 to 1957 and he began working for Ferrari in 1957, eventually becoming controller of experimental, Sports and GT car development. He worked at Ferrari as a developer, test driver and his developments there included the Ferrari 250 TR, the Ferrari 250 GT SWB, and the 1962 Ferrari 250 GTO.
Bizzarrini was fired by Ferrari during the revolt of 1961. He became part of Automobili Turismo e Sport ), a company started by the engineers to build a Formula 1 single seater and a GT sport car. One of ATSs financial backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to upgrade a Ferrari 250 GT SWB and this resulted in the Ferrari 250 GT SWB Drogo known as the Breadvan. Bizzarrinis engineering company, Societa Autostar, was commissioned to design a V-12 engine for a GT car to be built by another dissatisfied Ferrari customer, Lamborghini considered the resulting engine to be too highly strung, and ordered that it be detuned. Bizzarrini worked since 1964 for Iso Rivolta and developed three models, Iso Rivolta GT, Iso Grifo both A3L and A3C versions and his work was to develop a pressed steel frame chassis for Iso cars. Renzo Rivolta hired him as consultant to the Iso Gordon GT project which became the Iso Rivolta GT, the Iso Gordon GT prototype was developed from the Gordon-Keeble.
The Gordon Keeble GT was designed in 1960 by Giugiaro, Bizzarrini tested the car and was impressed by the powerful V8 Corvette engine and the rear De Dion tube used for the GT, Rivolta had me test the prototype. I liked its De Dion tube and especially the Corvette engine and it was the first time I had driven one. It was superior to Ferraris engines, having the same power, the Iso Rivolta GT was a Giugiaro designed four seater with beautiful body, speed and handling, and was a successful car for ISO with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine with a classic De Dion rear suspension design with pressed steel bodywork over pressed steel frame chassis
24 Hours of Le Mans
The 24 Hours of Le Mans is the worlds oldest active sports car race in endurance racing, held annually since 1923 near the town of Le Mans, France. It is one of the most prestigious races in the world and is often called the Grand Prix of Endurance. The event represents one leg of the Triple Crown of Motorsport, other events being the Indianapolis 500, since 2012, the 24 Hours of Le Mans has been a part of the FIA World Endurance Championship. In 2017, it will be the round of the season. The race has over the years inspired imitating races all over the globe, popularizing the 24-hour format at places like Daytona, Nürburgring, Spa-Francorchamps, and Bathurst. The American Le Mans Series and Europes Le Mans Series of multi-event sports car championships were spun off from 24 Hours of Le Mans regulations. At a time when Grand Prix motor racing was the dominant form of motorsport throughout Europe, Le Mans was designed to present a different test. Instead of focusing on the ability of a car company to build the fastest machines and this encouraged innovation in producing reliable and fuel-efficient vehicles, because endurance racing requires cars that last and spend as little time in the pits as possible.
At the same time, the layout of the track necessitated cars with better aerodynamics, while this was shared with Grand Prix racing, few tracks in Europe had straights of a length comparable to the Mulsanne. Additionally, because the road is public and thus not as meticulously maintained as permanent racing circuits, racing puts more strain on the parts, increasing the importance of reliability. The oil crisis in the early 1970s led organizers to adopt a fuel economy formula known as Group C that limited the amount of each car was allowed. Although it was abandoned, fuel economy remains important as new fuel sources reduced time spent during pit stops. Such technological innovations have had an effect and can be incorporated into consumer cars. This has led to faster and more exotic supercars as manufacturers seek to develop road cars in order to develop them into even faster GT cars. Additionally, in recent years hybrid systems have been championed in the LMP category as rules have changed to their benefit.
The race is held in June, leading at times to very hot conditions for drivers, particularly in closed vehicles with poor ventilation, the race begins in mid-afternoon and finishes the following day at the same hour the race started the previous day. Over the 24 hours, modern competitors often cover distances well over 5,000 km, the record is 2010s 5,410 km, six times the length of the Indianapolis 500, or approximately 18 times longer than a Formula One Grand Prix. Drivers and racing teams strive for speed and avoiding damage, as well as managing the cars consumables, primarily fuel, tires
A shooting-brake is a car body style that has evolved through several distinct meanings over its history. Shooting-brake originated as an early 19th century British term for a used to carry shooting parties with their equipment. The etymology of the brake is uncertain, initially a chassis used to break in horses. It is possible, that the brake has its origins in the Dutch word brik which means cart or carriage. The term was applied to custom-built wagons by high-end coachbuilders. In contemporary usage, the term shooting-brake has broadened to include a range of vehicles from five-door station wagons — to three-door models combining features of a wagon and a coupé. In 2006, The New York Times said the shooting-brake was conceived to take gentlemen on the hunt with their firearms, in 2014, Lawrence Ulrich of the New York Times said the shooting-brake is essentially a two-door station wagon. A brake was originally a robust carriage chassis hooked to spirited horses to break them, a shooting-brake became a variation of a wagonette—a vehicle with longitudinal seats in rows with either a rear door or side doors—provided with game and gun racks and accommodation for ammunition.
Early motorized safari vehicles were described as shooting-brakes with no windows or doors, instead roll-down canvas curtains were buttoned to the roof in the case of bad weather. These cars were heavy and comfortable in good weather and allowed quick, the term shooting-brake was subsequently applied to custom-built luxury estate cars altered for use by hunters and other sportsmen. The New York Times said the most famous shooting brakes had custom two-door bodies fitted to the chassis of pedigreed cars, citing Bentley, the 2006 editions of The Chambers Dictionary define the term shooting-brake as an archaic term for estate, or station wagon. In France, a wagon is marketed as a break, once having been called a break de chasse, literally translated. It makes use of the space it covers a little better than a normal coupé. Especially in America, every member of the family has their own car, the occasional use of the rear seat means you can do one of these cars, even if such a wagon lacks the everyday practicality of four doors.
Between 1965 and 1967 a limited number of variants, marketed as shooting-brakes, were manufactured by coachbuilder Harold Radford, based on the Aston Martin DB5, DB6. Aston Martin itself manufactured in-house a limited production variant of its Virage/Vantage. Torque magazine said the Mini Clubman is essentially a shooting-brake design, the 2006 Renault Altica concept was described as a shooting brake. In 2011, The New York Times described the newly introduced Ferrari FF as a shooting-brake, in 1999, Popular Mechanics presented a 2001 Jaguar five-door wagon variant of its S-Type, saying the term shooting-brake was interchangeable with station wagon
The Ferrari 250 is a sports car built by Ferrari from 1953 to 1964. The companys most successful line, the 250 series included several variants. It was replaced by the 275 and the 330, most 250 road cars share the same two wheelbases,2,400 mm for short wheelbase and 2,600 mm for long wheelbase. Most convertibles used the SWB type, nearly all 250s share the same Colombo Tipo 125 V12 engine. At 2,953 cc, it was notable for its weight and impressive output of up to 300 PS in the Testa Rossa. The V12 weighed hundreds of less than its chief competitors — for example. Ferrari uses the displacement of a cylinder as the model designation. The light V12 propelled the small Ferrari 250 racing cars to numerous victories, typical of Ferrari, the Colombo V12 made its debut on the race track, with the racing 250s preceding the street cars by three years. The first 250 was the experimental 250 S berlinetta prototype entered in the 1952 Mille Miglia for Giovanni Bracco, the car was entered at Le Mans and in the Carrera Panamericana.
The 250 S used a 2,250 mm wheelbase with a Tuboscocca tubular trellis frame, suspension was by double wishbones at the front, with double longitudinal semi-elliptic springs locating the live axle at the rear. The car had the drum brakes and worm-and-sector steering typical of the period, the dry-sump 3.0 L engine used three Weber 36DCF carburettors and was mated directly to a five-speed manual transmission. Following the success of the 250 S in the Mille Miglia, Pinin Farina created coupé bodywork which had a small grille, compact tail and panoramic rear window, and the new car was launched as the 250 MM at the 1953 Geneva Motor Show. Carrozzeria Vignales open barchetta version was a design whose recessed headlights. The 250 MMs wheelbase was longer than the 250 S at 2,400 mm, the V12 engines dry sump was omitted from the production car, and the transmission was reduced by one gear. Power was increased to 240 PS, the four-cylinder 625 TF and 735 S replaced the V12-powered 250 MM in 1953. The 250 MMs race debut was at the 1953 Giro di Sicilia with privateer Paulo Marzotto, a Carrozzeria Morelli-bodied 250 MM barchetta driven by Clemente Biondetti came fourth in the 1954 Mille Miglia.
The 1954250 Monza was and unusual hybrid of the light four-cylinder 750 Monza, the model used the 250 engine in the short-wheelbase chassis from the 750 Monza. The first two used the Pininfarina barchetta shape of the 750 Monza and a one-off 500 Mondial, two more 250 Monzas were built by Carrozzeria Scaglietti, an early use of the now-familiar coachbuilder
