Alfa Romeo Giulia (952)
The Alfa Romeo Giulia is a compact executive car produced by the Italian car manufacturer Alfa Romeo. It was unveiled in June 2015, with market launch scheduled for February 2016, it is the first saloon offered by Alfa Romeo after the production of the 159 ended in 2011; the Giulia is the first mass-market Alfa Romeo vehicle in over two decades to use a longitudinal rear-wheel drive platform, since the 75, discontinued in 1992. The Giulia was second in 2017 European Car of the Year voting and was named Motor Trend Car of the Year for 2018; the car was designed at the Centro Stile Alfa Romeo, by a team headed by Marco Tencone and including Senior Exterior Designer, Andrea Loi. along with Interior Chief Designer, Inna Kondakova and Senior Interior Designer, Manuele Amprimo. The Giulia has been the subject of a long gestation and delayed launch dates due to the design being sent back to the drawing board by Sergio Marchionne, CEO of Fiat Chrysler Automobiles, the parent company of Alfa Romeo at the time.
The new Giulia was unveiled to the press at the Museo Storico Alfa Romeo in Arese, on 24 June 2015, at an event which involved only the top-of-the-range Quadrifoglio variant and a rendition of "Nessun dorma" by Italian tenor Andrea Bocelli. The occasion coincided with the company's 105th anniversary, saw the company debut a restyled logo for all future Alfa Romeo models; the Giulia was presented under the new La meccanica delle emozioni slogan. The Giulia is the first model in the company's relaunch plan, which involves a €5 billion investment for an eight car line-up and a worldwide sales target of 400,000 by 2018—up from 74,000 in 2013, it is underpinned by an all-new, longitudinal-engine, rear-wheel drive platform developed for Alfa Romeo—codenamed "Giorgio". Development of the Giulia, along with development of the entire "Giorgio" project, has been overseen by the technical director of Ferrari, Philippe Krief; the Giulia uses a front-engine, rear-wheel-drive layout, featuring an 50% front and 50% rear weight distribution.
Suspension is independent all-around, of the double wishbone type at the front and multilink at the rear. All Giulia models employ a carbon-fibre drive shaft made by Hitachi Automotive Systems, as well as aluminium alloy shock towers, suspension components, front wings and doors. Four-wheel drive models will be offered. Depending on trim level it has a 6.5-inch or 8.8-inch colour display, optional Sport and Luxury Packs are available. The sport package includes sports steering wheel with added grip, aluminium inserts on the dashboard, centre console and door panels, Xenon headlights; the luxury package offers premium leather wood trim. The performance package includes mechanical limited-slip differential along with electronic suspension and paddle shifters on the steering column in the cars equipped with an automatic transmission; the base model Giulia, mid-level Super, loaded Speciale are powered by a 200 PS gasoline engine, or the choice of 150 PS or 180 PS turbo diesel engine. The base model comes with 16 inch alloys, the Super can be distinguished with 17 inch alloys and dual chrome exhaust tip for the diesel model.
The Speciale has 18 inch alloys, black brake calipers, leather sports seats from the Veloce. The Giulia Veloce was presented at the 2016 Paris International Motor Show held in October; the Veloce offers the choice of two engines: the 2.0-litre turbo petrol and the 2.2-litre diesel inline-4 engines, both equipped with an 8-speed automatic transmission and Alfa Q4 all-wheel drive system. The Veloce has a glossy black door trim. On the interior, it has black, red or tan leather sport seats and a sports steering wheel with a suede grip, aluminium inserts on the dashboard, central tunnel, door panels and Xenon headlights; the new petrol straight-4 engine produces a maximum power output of 280 PS at 5,250 rpm and a maximum torque of 400 N⋅m at 2,250 rpm. It has MultiAir electro-hydraulic valve activation system along with "2-in-1" " turbocharger system and direct injection with a 200-bar high pressure system; the 210 PS diesel all aluminum straight-4 engine comes with MultiJet II technology and electrically operated variable geometry turbocharger.
The Alfa Q4 all wheel drive system behaves like a rear-wheel drive vehicle: 100% of torque is distributed to the rear axle. As it reaches the wheel adherence limit, the system transfers up to 60% of the torque to the front axle. To ensure maximum speed of response in re-distributing torque, the system exploits a high mechanical over slippage between the two axles, which translates into segment-beating vehicle control in terms of traction and directional stability on bends; the new trim level between Veloce and Quadrifoglio was introduced at the 2018 Goodwood Festival of Speed, sitting between the standard Veloce and the high-powered Quadrifoglio models. Its exterior design is inspired by the Quadrifoglio with an optional carbon fibre pack; the high-performance Giulia Quadrifoglio was the first model in the new Giulia range. It was unveiled at Italy in June 2015, it made its official international debut at the 2015 Frankfurt Motorshow. The Quadrifoglio's main competitors are cars such as the Mercedes-AMG C63, BMW M3 and Cadillac ATS-V.
The Quadrifoglio is powered by an all-aluminium alloy, twin-turbocharged gasoline direct injection 90° V6 engine, with a single-cylinder displacement of just under half a litre, for a total of 2,891 cc (176.4 cu
Automotive design is the process of developing the appearance, to some extent the ergonomics, of motor vehicles, including automobiles, trucks, buses and vans. The functional design and development of a modern motor vehicle is done by a large team from many different disciplines included within automotive engineering, design roles are not associated with requirements for Professional or Chartered-Engineer qualifications. Automotive design in this context is concerned with developing the visual appearance or aesthetics of the vehicle, though it is involved in the creation of the product concept. Automotive design as a professional vocation is practiced by designers who may have an art background and a degree in industrial design or transportation design. Terminology used in the field is found in the glossary of automotive design; the task of the design team is split into three main aspects: exterior design, interior design, color and trim design. Graphic design is an aspect of automotive design.
Design focuses not only on the isolated outer shape of automobile parts, but concentrates on the combination of form and function, starting from the vehicle package. The aesthetic value will need to correspond to ergonomic utility features as well. In particular, vehicular electronic components and parts will give more challenges to automotive designers who are required to update on the latest information and knowledge associated with emerging vehicular gadgetry dashtop mobile devices, like GPS navigation, satellite radio, HD radio, mobile TV, MP3 players, video playback, smartphone interfaces. 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 designer responsible for the exterior of the vehicle develops the proportions and surfaces of the vehicle. Exterior design is first done by a series of manual drawings. Progressively, drawings that are more detailed are executed and approved by appropriate layers of management.
Industrial plasticine and or digital models are developed from, 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 clay model is first designed in a computer program and "carved" using the machine and large amounts of clay. In times of high-class 3d software and virtual models on power walls, the clay model is still the most important tool to evaluate the design of a car and, therefore, is used throughout the industry; the designer responsible for the vehicles' interior develops the proportions, shape and surfaces for the instrument panel, door trim panels, pillar trims, etc. Here the emphasis is on 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, so on.
Color, contrast and pattern must be combined to give the vehicle a unique interior environment experience. Designers work 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 projects two to three model years in the future. Trend boards are created from this 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. The design team develops graphics for items such as: badges, dials, kick or tread strips, liveries; the sketches and rendering are transformed into 3D Digital surface modelling and rendering for real-time evaluation with Math data in initial stages. During the development process succeeding phases will require the 3D model developed to meet the aesthetic requirements of a designer and well as all engineering and manufacturing requirements.
The developed CAS digital model will be re-developed for manufacturing meeting the Class-A surface standards that involves both technical as well as aesthetics. This data will be further developed by Product Engineering team; these modelers have a background in Industrial design or sometimes tooling engineering in case of some Class-A modelers. Autodesk Alias and ICEM Surf are the two most used software tools for Class-A development. Several manufacturers have varied development cycles for designing an Automobile, but in practice these are the following. Design and User Research Concept Development sketching CAS Clay modeling Interior Buck Model Vehicle ergonomics Class-A Surface Development Colour and Trim Vehicle GraphicsThe design process occurs concurrently with other product Engineers who will be engineering the styling data for meeting performance and safety regulations. From mid-phase and forth interactions between the designers and product engineers culminates into a finished product be manufacturing ready.
Apart from this the Engineering team parallelly works in the following areas. Product Engineering, NVH Development team, Prototype
Alfa Romeo Giulia
Alfa Romeo Giulia is the name of three not directly related models by the Italian car manufacturer Alfa Romeo. The first is a line of sporty four-door compact executive cars produced from 1962 to 1978, the second is an updated up-engined Spider and Sprint Speciale Giuliettas, the third Giulia is a compact executive car unveiled in 2015. Alfa Romeo was one of the first mainstream manufacturers to put a powerful engine in a light-weight 1 tonne four-door car for mass production; the Type 105 Giulia was equipped with a light alloy twin overhead camshaft four-cylinder engine similar to that of the earlier Giulietta range, available in 1.3-litre and 1.6-litre versions. Various configurations of carburetors and tuning produced power outputs from about 80 to about 110 bhp, coupled in most cases to 5-speed manual transmission. Giulia sedans were noted for lively handling and impressive acceleration among small European four-door sedans of their era considering modest engine sizes offered; the popular Super version with the twin carburettor 1.6 litre engine had a top speed of 170 km/h and accelerated from 0 to 100 km/h in about 12 seconds, better than many sports cars of the late 1960s and early 1970s.
When leaving the factory all variations of the Giulia fitted either Pirelli Cinturato 165HR14 tyres or Pirelli Cinturato 155HR15 tyres. The styling of the boxy four-door notchback saloon was somewhat wanting; the engine bay and boot were all square shaped, buffered somewhat by details on the grill, roofline and boot. Use of a wind tunnel during development led to a aerodynamic shape that produced a drag coefficient of Cd=0.34 low for a saloon of the era. The Giulia Spider was succeeded by the Alfa Romeo Spider in 1966. Note: chassis and engine type numbers displayed in italic for each model are sourced from Fusi 1978, pages 841–848. Tipo: 105.14, 105.08, 105.09. Engine: 00514. Unveiled on 27 June 1962 at the Autodromo Nazionale Monza, the Alfa Romeo Giulia TI was the first of the Giulia family of cars to be introduced, its 1,570 cc Alfa Romeo Twin Cam engine was fitted with a single Solex 33 PAIA 7 twin-choke down-draft carburettor, produced 92 DIN-rated PS or 106 SAE-rated PS at 6,200 rpm. The "TI" nomenclature referred to a class of Italian saloon car racing known as "Turismo Internazionale", had been applied to higher-performance versions of the 1900 and Giulietta saloons in the 1950s.
However, for the Giulia saloon, the TI was at first the only version available, with the introduction of the TI Super and Super, the TI became the base version in the 1.6-litre engine class. A distinguishing feature of the original Giulia were drum brakes on all corners, the front ones of the three-shoe type like on late Giuliettas; the car was marketed as a six-seater, thanks to a standard column-mounted shifter and a split bench front seat—though Italian car magazine Quattroruote found it rather a comfortable four-seater. Other notable interior features of the early models were mottled cloth and vinyl upholstery, a grey, trapezoid instrument panel including a strip speedometer, a black steering wheel with two ivory-coloured spokes and a chrome half horn ring. In May 1964 a floor shifter became available, to be ordered in conjunction with the newly introduced separate front seats. Around the same time a right hand drive model variant entered production, with floor shifter only. In February 1966 several changes were made.
The floor shifter became standard. From outside these TIs can be recognized by L-shaped chrome strips around the tail lights which supplanted the previous C-shaped ones. Production of the Giulia TI ceased during 1967. Tipo: 105.16. Engine: 00516; the Alfa Romeo Giulia TI Super was a special road-going sports model produced in limited numbers, fitted with a more powerful engine and a number of weight saving components, intended for racing use. It was introduced to the press at the Monza race track on 24 April 1963. In total only 501 were made, 178 in 1963 and 323 1964. On 2 May 1964 the TI Super received international FIA and Italian CSAI homologation for racing, was extensively campaigned in the European Touring Car Challenge. Today the Giulia TI Super is rare and considered desirable by collectors; the TI Super's 1,570 cc engine was the same installed on the Giulia Sprint Speciale coupé—though bearing a different type code. It was fitted with two twin-choke horizontal Weber 45 DCOE 14 carburettors and, as on the Sprint Speciale, produced 112 DIN-rated PS or 129 SAE-rated PS at 6,500 rpm, pushing top speed to over 185 km/h.
Dry weight was 910 kilograms compared to 1,000 kg of the standard Giulia TI. Parts contributing to the weight reduction were mesh grilles replacing the inner pair of head lamps, bumpers without overriders, fixed front quarter windows, Plexiglas rear windows, magnesium alloy wheels with hubcaps similar in appearance to the standard steel wheels of the TI. Braking was by discs all around. Cars built from August 1964 used the bodyshell of the TI with mounting points for the brake servo, but wer
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, 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 to pistons, turbine blades, rotor or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy; the first commercially successful internal combustion engine was created by Étienne Lenoir around 1859 and the first modern internal combustion engine was created in 1876 by Nikolaus Otto. The term internal combustion engine refers to an engine in which combustion is intermittent, such as the more familiar four-stroke and two-stroke piston engines, along with variants, such as the six-stroke piston engine and the Wankel rotary engine. A second class of internal combustion engines use continuous combustion: gas turbines, jet engines and most rocket engines, each of which are internal combustion engines on the same principle as described.
Firearms are a form of internal combustion engine. In contrast, in external combustion engines, such as steam or Stirling engines, energy is delivered to a working fluid not consisting of, mixed with, or contaminated by combustion products. Working fluids can be air, hot water, pressurized water or liquid sodium, heated in a boiler. ICEs are powered by energy-dense fuels such as gasoline or diesel fuel, liquids derived from fossil fuels. While there are many stationary applications, most ICEs are used in mobile applications and are the dominant power supply for vehicles such as cars and boats. An ICE is fed with fossil fuels like natural gas or petroleum products such as gasoline, diesel fuel or fuel oil. There is a growing usage of renewable fuels like biodiesel for CI engines and bioethanol or methanol for SI engines. Hydrogen is sometimes used, can be obtained from either fossil fuels or renewable energy. Various scientists and engineers contributed to the development of internal combustion engines.
In 1791, John Barber developed the gas turbine. In 1794 Thomas Mead patented a gas engine. In 1794, Robert Street patented an internal combustion engine, the first to use liquid fuel, built an engine around that time. In 1798, John Stevens built the first American internal combustion engine. In 1807, French engineers Nicéphore and Claude Niépce ran a prototype internal combustion engine, using controlled dust explosions, the Pyréolophore; this engine powered a boat on France. The same year, the Swiss engineer François Isaac de Rivaz built an internal combustion engine ignited by an electric spark. In 1823, Samuel Brown patented the first internal combustion engine to be applied industrially. In 1854 in the UK, the Italian inventors Eugenio Barsanti and Felice Matteucci tried to patent "Obtaining motive power by the explosion of gases", although the application did not progress to the granted stage. 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, four-cycle engine. In 1879, Karl Benz patented a reliable two-stroke gasoline engine. In 1886, Karl Benz began the first commercial production of motor vehicles with the internal combustion engine. In 1892, Rudolf Diesel developed compression ignition engine. In 1926, Robert Goddard launched the first liquid-fueled rocket. In 1939, the Heinkel He 178 became the world's 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. Traditionally, electric motors are not referred to as "engines". In boating an internal combustion engine, installed in the hull is referred to as an engine, but the engines that sit on the transom are referred to as motors. 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.
Rotary engines of the Wankel design are used in some automobiles and motorcycles. Where high power-to-weight ratios are required, internal combustion engines appear in the form of combustion turbines or Wankel engines. Powered aircraft uses an ICE which may be a reciprocating engine. Airplanes can instead use jet engines and helicopters can instead employ turboshafts. In addition to providing propulsion, airliners may employ a separate ICE as an auxiliary power unit. Wankel engines are fitted to many unmanned aerial vehicles. ICEs drive some of the large electric generators, they are found in the form of combustion turbines in combined cycle power plants with a typical electrical output in the range of 100 MW to 1 GW. The high temperature exhaust is used to superheat water to run a steam turbine. Thus, the efficiency is higher because more energy is extracted from the fuel than what could be extracted by the co
Alfa Romeo RL
The Alfa Romeo RL was produced between 1922-1927. It was Alfa's first sport model after World War I; the car was designed in 1921 by Giuseppe Merosi. It had a straight-6 engine with overhead valves. Three different versions were made: Normale and Sport. RL total production was 2640; the RLTF was the race version of RL - it weighed half of normal versions, the engine had seven main bearings instead of four and double carburetors. In 1923 Alfa's race team had drivers like Ugo Sivocci, Antonio Ascari, Giulio Masetti and Enzo Ferrari. Sivocci's car had green cloverleaf symbol on white background and when he won Targa Florio 1923, that symbol was to become the Alfa team's good luck token. In 1927, 2 different RLSS were entered in the first Mille Miglia, but both dropped out after leading the race. A 1925 RLSS version with rare, original bodywork by Thornton Engineering Company in Bradford, UK, is on permanent display in the Brooklands exhibit at the Simeone Foundation Automotive Museum in Philadelphia, PA, USA.
It is one of only 9 RLSS still in existence
Alfa Romeo 158/159 Alfetta
The Alfa Romeo 158/159 known as the Alfetta, is a Grand Prix racing car produced by Italian manufacturer Alfa Romeo. It is one of the most successful racing cars produced- the 158 and its derivative, the 159, took 47 wins from 54 Grands Prix entered, it was developed for the pre-World War II voiturette formula and has a 1.5-litre straight-8 supercharged engine. Following World War II, the car was eligible for the new Formula One introduced in 1947. In the hands of drivers such as Nino Farina, Juan-Manuel Fangio and Luigi Fagioli, it dominated the first two seasons of the World Championship of Drivers; the first version of this successful racing car, the 158, was made during 1937/1938. The main responsibility for engineering was given to Gioacchino Colombo; the car's name refers to eight cylinders. The voiturette class was for racing cars with 1.5-litre engines, standing in the same relation to the top'Grand Prix' formula as the GP2 series does to Formula One today. Alfa's 3-litre racing cars in 1938 and 1939 were the Tipo 308, 312 and 316.
The 158 debuted with the works Alfa Corse team at the Coppa Ciano Junior in August 1938 at Livorno, where Emilio Villoresi took the car's first victory. At that time the 1479.56 cc engine produced around 200 bhp at 7000 rpm. with the help of a single-stage Roots blower. More success came at the Coppa Acerbo, Coppa Ciano and Tripoli Grand Prix in May 1940. Soon World War II stopped development of the car for six years. After the war the engine was developed further to push out 254 bhp in 1946. In 1947, the Alfetta was put back into service; the new rules allowed 1500 cc supercharged and 4500 cc aspirated engines. The 158 was modified again, this time to produce over 300 bhp and was denoted as Tipo 158/47; the car made a tragic debut in the 1948 Swiss Grand Prix where Achille Varzi lost control of his car and was killed. Another loss for the team came in practice for the 1949 Buenos Aires Grand Prix, where Jean-Pierre Wimille was killed in an accident. In 1950, the 158 was eligible for the new World Championship of Drivers.
The car won every race. The Alfa Romeo team included talented drivers such as Giuseppe Farina and Juan Manuel Fangio, the latter of whom won the World Drivers' Championship five times. At the end of the 1950 season, a further updated version known as the 159 was produced, used for the 1951 season; this version had reworked rear suspension, the old swing axle was replaced with a De-Dion axle and the engine produced around 420 bhp at 9600 rpm. In order to achieve this power however, the simplistically designed engine had been been fitted with larger superchargers over time; this fact, combined with the rich mixture required to burn methanol in the engine resulted in poor fuel economy - the 159 achieved 1 1⁄2 miles to the gallon, compared to the Talbot-Lagos of the time, which delivered 10 miles to the gallon. The British Grand Prix at Silverstone was the first Formula One Grand Prix not won by an Alfa because Fangio and Farina both had to stop twice to re-fuel their cars – and the Ferrari of José Froilán González did better on fuel and would go on to win the race, with Fangio second.
Still, the Alfa had the edge on performance and with wins in Switzerland and Spain, Fangio won his first of five championships that year. For their second-to-last World Championship race, the Italian Grand Prix at Monza, Alfa Romeo introduced a new evolution version known as the 159M, the "M" standing for Maggiorata. After an unsuccessful bid by Alfa Romeo to obtain government assistance to meet development costs, the team announced their retirement from Grand Prix racing at the end of 1951. This, combined with problems for other Formula One teams lead to a decree by the FIA that all Grand Prix races counting towards the World Championship of Drivers in 1952 and 1953 would be for cars complying with Formula Two rather than Formula One; the car's last Grand Prix win came in 1953 at Italy. * The Constructors' Championship was not awarded until 1958
