Alfa Romeo Giulietta (940)
The Alfa Romeo Giulietta is a small family car produced by the Italian automaker Alfa Romeo. Giulietta production started towards the end of 2009 and the model was introduced at the March 2010 Geneva Motor Show. In a viability plan forwarded to the US Government in February 2009, Chrysler reported that the 147 replacement would come to market as the Milano and that it could be built in the USA. However, as of early 2010 Fiat was instead planning to concentrate on bringing larger models to the US, such as the Giulia; the Giulietta came in second place in the 2011 European Car of the Year awards. Between 2010 and 2019 over 400,000 Giuliettas were built, it is current top Alfa sales with about 32,000 cars per year. The 2010 Giulietta is available only as a 5-door hatchback; the Giulietta got its Italian dealer presentation on 22 and 23 May 2010. The Giulietta advertising campaign is made with Hollywood actress Uma Thurman; the end of the advert features the car's mottos -'I am Giulietta, I am such stuff as dreams are made on' and'Without heart, we would be mere machines'.
The platform used is Fiat Group’s Compact called as "C-Evo" during the planning stage. This is an all new platform. Fiat Group used around 100 million euros to re-engineer the C-platform used for the Fiat Stilo, Fiat Bravo and Lancia Delta, into C-Evo, it has a longer wheelbase, shorter overhangs and an advanced new type of MacPherson strut front suspension and multi-link rear suspension. Depending on the market and trim level, 16, 17, or 18 inch wheels are available. Available tire sizes are 205/55 R16, 225/45 R17, 225/40 R18; the wheels use a 5-hole pattern with a 110 mm bolt circle. The length of the Giulietta is around 4.3 metres. Only a five-door body is available for sale. At the 2013 Frankfurt International Motor Show Alfa Romeo presented an updated Giulietta. Trim changes include a new Uconnect infotainment system with 5" or 6.5" Radionav touchscreen, a new front grille, a chrome-plated frame for the fog lights, a new and more supportive seat design, new wheels, as well as new exterior colours: Moonlight Pearl, Anodizzato Blue and Bronze.
A new diesel engine variant has arrived, the two-litre JTDM 2, developing 150 PS and 380 N⋅m. In the 2014 range, all engines comply with Euro 5+ emission standards. Debuting at 2016 Geneva Motor Show, New Giulietta with facelifted front resembling Giulia and with new updated brand logo and new lettering. Trim line up will be changed to Giulietta Super and Giulietta Veloce. New body colour, new rims designs. Previous Giulietta QV will now be changed into sporty Veloce trim available with 240 PS engine and TCT transmission. Debuting will be a new 1.6 JTDm 120 PS TCT diesel engine. For 2019 Giulietta has updated engines, all Euro 6 D: a 1.4-litre 120 PS turbo petrol, a 1.6-litre 120 PS Multijet with manual or Alfa TCT automatic transmission, a 2.0-litre 170 PS Multijet with Alfa TCT. The top of the range model is a version with 1.75 L turbocharged TBi engine rated 235 PS, lowered ride height, 18-inch Spoke design alloy wheels with dark titanium finish and 225/40 R18 tires plus 18-inch 5 hole design alloy wheels as an option.
1750 is an engine size which has its roots in Alfa Romeo's history, with 1.75 L engines being used to power some of Alfa Romeo's first cars. The UK version is sold as the Giulietta Cloverleaf. In Geneva Motor Show Alfa Romeo introduced a new Quadrifoglio Verde, it has new 1,742 cc Turbo gasoline direct injection aluminium-block Inline-four engine now upgraded to 240 PS at 5750 rpm and 340 N⋅m at 2000 rpm of torque and Alfa TCT 6-speed twin dry clutch transmission borrowed from the Alfa Romeo 4C. With new engine the Giulietta's flagship can exceed 240 km/h and accelerate from 0 to 100 km/h in only 6.0 seconds. This new facelifted version was premiered with a limited'Launch Edition', recognizable by the black-finish on the sills all round. Available in new matt Grigio Magnesio Opaco along with Rosso Alfa and Rosso Competizione; each car has its own numbered plaque. Around 700 units were made; the GTS Q2 is a version of Hong Kong market version GT Q2 with Sport Package. It includes the engine from 1.4 L TB MultiAir TCT, with a 6-speed TCT transmission.
It is a version using petrol fuel types. It includes Euro 5-compliant 1.4-litre turbo engine rated 120 PS at 5000 rpm and 206 N⋅m at 1750 rpm, three different trim levels for all European markets, 38-litre toroid type LPG tank at spare wheel housing, 6-speed manual transmission. The LPG version was unveiled in 2011 Bologna Motor Show. At Centro Sperimentale di Balocco in October 2014, Alfa Romeo launched a 60th anniversary edition of the Giulietta; the Giulietta Sprint pays homage to the 1954 Giulietta which promised good performance at an affordable price. The 2014 Giulietta Sprint features a unique 1.4-litre MultiAir petrol engine rated 152 PS at 5500 rpm and 250 N⋅m at 1750 rpm. Other changes include a carbon fibre effect interior trim, sporty exterior styling including side skirts, rear diffuser and oversized exhaust; the Squadra Corse TCT is a limited edition version of the Giulietta Quadrifoglio Verde made for
Alfa Romeo Tipo 33
The Alfa Romeo Tipo 33 was a sports racing prototype raced by the Alfa Romeo factory-backed team between 1967 and 1977. These cars took part for Sport Cars World Championship, Nordic Challenge Cup and CanAm series. A small number of road going cars were derived from it in 1967, called Alfa Romeo 33 Stradale. With the 33TT12 Alfa Romeo won the 1975 World Championship for Makes, with the 33SC12 the 1977 World Championship for Sports Cars, taking the first place in all eight of the championship races. Alfa Romeo started development of the Tipo 33 in the early 1960s, with the first car being built in 1965, it was sent for additional changes to be made. It used an Alfa Romeo TZ2 straight-4 engine; the 2000 cc Tipo 33 mid-engined prototype debuted on 12 March 1967 at the Belgian hillclimbing event at Fléron, with Teodoro Zeccoli winning. The first version was named as “periscope” because it had characteristic air inlet, it was powered with a large-diameter tube frame. The original T33 proved unreliable and uncompetitive in the 1967 World Sportscar Championship season, its best result a 5th at the Nürburgring 1000, co-driven by Zeccoli and Roberto Bussinello.
In 1968, Alfa's subsidiary, created an evolution model called 33/2. A road version, dubbed Alfa Romeo 33 Stradale, was introduced. At the 24 Hours of Daytona, the Porsche 907 with 2.2L engines were dominating the overall race, but Alfa took the 2-litre class win, with Udo Schütz and Nino Vaccarella. Win was repeated at the Targa Florio, where Nanni Galli and Ignazio Giunti took second place overall, followed by teammates Lucien Bianchi and Mario Casoni. Galli and Giunti won the class at the Nürburgring 1000 km, where the 2.5L version finished for the first time, 4th place in the 3.0L class with Schütz and Bianchi. However, in most races, the Alfa drivers were outclassed by their Porsche rivals which used bigger engines. In 1968, the car was used by privateers, winning its class in the 1000km Monza, Targa Florio and Nürburgring races. At the end of season Alfa Romeo had finished third in the 1968 International Championship for Makes. A total of 28 cars were built during 1968, allowing the 33/2 to be homologated as a Group 4 Sports Car for 1969.
The Alfa Romeo 33/3 made its debut in 1969 at the 12 Hours of Sebring. The engine was enlarged to 2998 cc with 400 hp, which put the 33/3 in the same class as the Porsche 908 and the Ferrari 312P; the chassis was now a monocoque. The new car did poorly at Sebring and Alfa did not take part in Le Mans after Lucien Bianchi's death in a practice session; the car took a couple of wins in smaller competitions but overall the 1969 season was not a successful one, Alfa Romeo was placed seventh in the 1969 International Championship for Makes. In 1970 the bigger 5.0L Porsche 917 and Ferrari 512 dominated, yet Toine Hezemans and Masten Gregory took third overall at Sebring, Andrea De Adamich and Henri Pescarolo won their class in the 1000km Zeltweg, finishing second overall. In 1970, an Alfa T 33/3 was one of the "actors" of Steve McQueen's movie Le Mans, released in 1971. In 1971 the Alfa Romeo racing effort was successful. Rolf Stommelen and Nanni Galli won their class at the 1000km Buenos Aires, before taking another class win at Sebring.
De Adamich and Pescarolo won outright at the 1000km Brands Hatch, a significant result against the "invincible" 917s. They took a class win at Monza and another one at Spa. At the Targa Florio and Hezemans won outright, followed by teammates De Adamich and Gijs Van Lennep. Hezemans and Vaccarella won their class at Zeltweg, De Adamich and Ronnie Peterson won overall at Watkins Glen. Alfa Romeo finished the season second place in the championship. In 1972 the 5 litre Group 5 Sports Cars were banned and the 3 litre cars of Alfa Romeo and Matra, redesignated as Group 5 Sports Cars, competed together for outright victories. A 4 litre version was entered to 1972 and 1974 CanAm series by Otto Zipper, the driver was Scooter Patrick. Autodelta was one of entrants with T33/4 in season 1974; the T33/3 version was used in the CanAm series earlier. The 33 TT 12 appeared in 1973 with the Carlo Chiti-designed 12 cylinder 3.0L flat engine. The 1973 season was more or less development time and in 1974 the car won at Monza 1000 km and finished the season with second place in the championship.
It wasn’t until 1975 that, after years of trying, Alfa Romeo won the 1975 World Championship for Makes. The season was one of total domination with seven wins in eight races. Winning drivers were: Arturo Merzario, Vittorio Brambilla, Jacques Laffite, Henri Pescarolo, Derek Bell and Jochen Mass. For 1976 Autodelta was concentrating on other things and the car was used in competitions; the successor of the 33TT12 1976 was SC referring to SCatolato, a boxed chassis. The 3.0 L flat-12 engine now produced 520 bhp. With this car Alfa Romeo won the 1977 World Championship for Sports Cars, the 33SC12s driven by Arturo Merzario, Jean-Pierre Jarier and Vittorio Brambilla having won every race in the series. At the Salzburgring the car reached an average speed of 203.82 km/h. The SC12 Turbo was Alfa's first twin turbocharged 12 cylinder engine and it was introduced around the same time as Renault's Formula One turbo engine. In the Alfa Romeo engine e
A car platform is a shared set of common design and production efforts, as well as major components over a number of outwardly distinct models and types of cars from different, but somewhat related marques. It is practiced in the automotive industry to reduce the costs associated with the development of products by basing those products on a smaller number of platforms; this further allows companies to create distinct models from a design perspective on similar underpinnings. A basic definition of a platform in cars, from a technical point of view, includes: underbody and suspensions — where the underbody is made of front floor, engine compartment and frame. Key mechanical components that define an automobile platform include: The floorpan, which serves as a foundation for the chassis and other structural and mechanical components Front and rear axles and the distance between them - wheelbase Steering mechanism and type of power steering Type of front and rear suspensions Placement and choice of engine and other powertrain componentsPlatform sharing is a product development method where different products and the brand attached share the same components.
The purpose with platform sharing is to reduce the cost and have a more efficient product development process. The companies gain on reduced procurement cost by taking advantage of the commonality of the components. However, this limits their ability to differentiate the products and imposes a risk of losing the tangible uniqueness of the product; the companies have to make a trade-off between reducing their development costs and the degree of differentiation of the products. One of the first car companies to use this product development approach was General Motors for in 1908. General Motors used a single chassis for certain class of model across most of its brands like Chevrolet, Buick and Oldsmobile. Chrysler Corporation would use the same for Plymouth and DeSoto and Dodge cars. Ford followed the same principle for Mercury in US markets; the chassis unit was common with many shared mechanical components while the Exterior styling and Interior trims were designed according to its individual brand and category.
In recent years for Monocoque chassis, the Vehicle platform-sharing combined with advanced and flexible-manufacturing technology enable automakers to reduce product development and changeover times, while modular design and assembly allow building a greater variety of vehicles from one basic set of engineered components.. Shown below is the Nissan MS platform where vehicles ranging from 5-door hatchback, sedan to compact SUV and Minivan were built on common floor panel and many shared various functional assemblies such as engine and chassis components. Many vendors refer to this as vehicle architecture; the concept of product architecture is the scheme by which the function of a product is allocated to physical components. The use of a platform strategy provides several benefits: Greater flexibility between plants, Cost reduction achieved through using resources on a global scale, Increased utilization of plants, Reduction of the number of platforms as a result of their localization on a worldwide basis.
The car platform strategy has become important in new product development and in the innovation process. The finished products have to be responsive to market needs and to demonstrate distinctiveness while — at the same time — they must be developed and produced at low cost. Adopting such a strategy affects the development process and has an important impact on an automaker's organizational structure. A platform strategy offers advantages for the globalization process of automobile firms; because the majority of time and money by an automaker is spent on the development of platforms, platform sharing affords manufacturers the ability to cut costs on research and development by spreading the cost of the R&D over several product lines. Manufacturers are able to offer products at a lower cost to consumers. Additionally, economies of scale are increased. A "platform" was a shared chassis from a previously-engineered vehicle, as in the case for the Citroën 2CV platform chassis used by the Citroën Ami and Citroën Dyane, Volkswagen Beetle frame under the Volkswagen Karmann Ghia.
But these two manufacturers made vastly different category of vehicles under using the same chassis design at different years though the primary vehicle was still in production. In the USA platform sharing has been a common practice since the 1960s, when GM used the same platform in the development of the Pontiac LeMans, the Buick Skylark, the Chevrolet Chevelle, the Oldsmobile Cutlass. In the 1980s, Chrysler's K-cars all wore a badge with the letter "K" to indicate their shared platform. In stages, the "K" platform was extended in wheelbase, as well as use for several of the Corporation's different models. GM used similar strategies with its "J" platform. Subsequently GM introduced its "A" bodies for the same four divisions using the same tread width/wheelbase of the "X" body platform, but with larger body work to make the cars seem larger, with larger trunk compartments, they were popular through the 1980s, primarily. Cadillac started offering a "J" body model called the Cimarron, a much gussied up version of the other four brands' platform siblings.
A similar strategy applied to what is known as the N-J-L platform, arguably the most prolific of GM's efforts on one platform. Once more, GM's four lower level divis
Fábrica Nacional de Motores
Fábrica Nacional de Motores was a Brazilian manufacturer of engines and motor vehicles based in the Xerém district of Duque de Caxias near Rio de Janeiro that operated between 1942 and 1988. The company was created 1942 by the Brazilian state as part of the Estado Novo agenda of President Getúlio Vargas, it was one of several business launched by the state during this period to kick start an industrial sector in Brazil. The company produced American Curtiss-Wright aircraft engines under license along with ammunition, bicycles and refrigerators. After the Second World War it was decided to diversify production; the government was keen to launch a vehicle manufacturing industry. In 1949 an agreement was reached with the Italian manufacturer, Isotta Fraschini, whereby FNM would produce the Milanese company's heavy trucks under license. Isotta Fraschini commercial vehicles enjoyed an excellent reputation at this time, but the Italian company was economically troubled, although its formal bankruptcy would be put off till the end of 1951.
The disappearance of Isotta Fraschini as a vehicle manufacturer left FNM looking for a new technology partner. In 1952 an agreement was signed with another Milanese vehicle manufacturer. Unusually in Europe, Alfa Romeo was a state owned business, following bankruptcy and a government rescue in the 1930s. Under the agreement with Alfa Romeo, FNM would manufacture Alfa Romeo's commercial vehicle range under license. Though little known north of the Alps, Alfa Romeo commercial vehicles were well established in Italy, other south European markets. Between 1956 and 1960 FNM built more than 15,000 heavy trucks of Alfa Romeo design: it manufactured the chassis for buses and coaches. In the Brazilian heavy truck sector which FNM dominated till the early 1970s, FNM was the only manufacturer. Trucks produced by FNM were nicknamed "Fenemê". In the mid-fifties a company called Fabral S. A. a collaboration between Alfa Romeo and Brazilian investor Matarazzo, was set up to build the Alfa Romeo 2000. The car was to be built in the state of São Paulo.
The Matarazzo Group backed out in 1958, following troubled discussions about the suitability of building luxurious cars in poor Brazil. After pressure from then-President Juscelino Kubitschek FNM, in which Alfa Romeo held a minority interest, took over the project. In 1960 FNM's first passenger car was launched, the FNM 2000, a Brazilian version of the series 102 Alfa Romeo 2000 four-door sedan; the factory ended up being built in the Xerém neighborhood, of Duque de Caxias, Rio de Janeiro instead. The engine was the same 1,975 cc twin camshaft unit found in the Italian product, but detuned to produce only 95 PS and the car received the FNM logo; this series of cars was named "J. K." in honor of President Kubitschek who had helped make the deal take place. This was by far the most luxurious, most expensive, car built in Brazil in the period. A coupé version was offered from 1966. Known as the FNM Onça, the coupé did not follow the line of any Alfa Romeo design, but featured an elegant locally designed body unmistakably reminiscent of the original Ford Mustang.
The regular FNM 2000, was followed by more powerful versions, culminating with the 130 PS TIMB, now boasting usefully more power than was claimed for its Alfa Romeo cousins of the time. The TIMB featured a flat bonnet with a lower-mounted grille, as suggested by Lincoln Tendler aiming a better aerodynamic penetration, a divided front bumper to accommodate the lower centerpiece; this same front design was used for the succeeding FNM 2150, with some detail differences. In 1968 Alfa Romeo acquired a controlling share in the hitherto state-owned FNM business; the next year the FNM 2000 was replaced by a restyled version, the FNM 2150, the most obvious visual differences affecting the front of the car. For this application the twin camshaft four cylinder engine saw its capacity increased to 2132 cc, performance was further enhanced through the installation of a better set of carburetors; the five-speed gearbox was the same one used in all cars made up to that moment. The FNM 2150 would continue in production from 1969 till 1974.
In 1971, another coupé called. Based on chassis and mechanics of the FNM/JK 2150 cc model, the car was designed by Brazilian designer Toni Bianco. Only a few hand built examples were produced, but the stylish coupé may have helped the public image of the by now aging design of the mainstream FNM 2150. Bianco made some sporting creations carrying his own name. Alfa Romeo had disposed of its commercial vehicle operations in Italy in the 1960s, in 1973 the FNM commercial vehicle business was sold to Fiat's industrial vehicle division, while Alfa Romeo retained responsibility for the FNM automobile business – subsequently FNM's commercial vehicle business ended up being absorbed into Fiat's Brazilian Iveco business. 1974 saw the FNM 2150 replaced with the Alfa Romeo 2300. This was the end for the FNM badged cars: the FNM badge itself inspired by the Alfa Romeo badge, was replaced on this car with an actual Alfa Romeo badge; the general look of the new car was similar to that of the Italian built Alfetta sedan, designed by Giuseppe Scarnati and first offered in Europe in 1972, although the Brazilian car was 41 centimetres longer and 7 centimetres wider than the Alfetta.
Under the skin, the 2300 was based technically on the older
Overhead camshaft abbreviated to OHC, is a valvetrain configuration which places the camshaft of an internal combustion engine of the reciprocating type within the cylinder heads and drives the valves or lifters in a more direct manner compared with overhead valves and pushrods. Compared with OHV pushrod systems with the same number of valves, the reciprocating components of the OHC system are fewer and have a lower overall mass. Though the system that drives the camshafts may be more complex, most engine manufacturers accept that added complexity as a trade-off for better engine performance and greater design flexibility; the fundamental reason for the OHC valvetrain is that it offers an increase in the engine's ability to exchange induction and exhaust gases. Another performance advantage is gained as a result of the better optimised port configurations made possible with overhead camshaft designs. With no intrusive pushrods, the overhead camshaft cylinder head design can use straighter ports of more advantageous cross-section and length.
The OHC design allows for higher engine speeds than comparable cam-in-block designs, as a result of having lower valvetrain mass. The higher engine speeds thus allowed increases power output for a given torque output. Disadvantages of the OHC design include the complexity of the camshaft drive, the need to re-time the drive system each time the cylinder head is removed, the accessibility of tappet adjustment if necessary. In earlier OHC systems, including inter-war Morrises and Wolseleys, oil leaks in the lubrication systems were an issue. Single overhead camshaft is a design. In an inline engine, this means there is one camshaft in the head, whilst in an engine with more than one cylinder head, such as a V engine or a horizontally-opposed engine – there are two camshafts, one per cylinder bank. In the SOHC design, the camshaft operates the valves traditionally via a bucket tappet. SOHC cylinder heads are less expensive to manufacture than double overhead camshaft cylinder heads. Timing belt replacement can be easier since there are fewer camshaft drive sprockets that need to be aligned during the replacement procedure.
SOHC designs offer reduced complexity compared with overhead valve designs when used for multivalve cylinder heads, in which each cylinder has more than two valves. An example of an SOHC design using shim and bucket valve adjustment was the engine installed in the Hillman Imp, a small, early-1960s two-door saloon car with a rear-mounted aluminium-alloy engine based on the Coventry Climax FWMA race engines. Exhaust and inlet manifolds were both on the same side of the engine block; this did, offer excellent access to the spark plugs. In the early 1980s, Toyota and Volkswagen Group used a directly actuated SOHC parallel valve configuration with two valves for each cylinder; the Toyota system used hydraulic tappets. The Volkswagen system used bucket tappets with shims for valve-clearance adjustment; the multivalve Sprint version of the Triumph Slant-4 engine used a system where the camshaft was placed directly over the inlet valves, with the same cams that opened the intake valves directly opening the exhaust valves via rocker arms.
Honda used a similar valvetrain system in their motorcycles, using the term "Unicam" for the concept. This system uses one camshaft for each bank of cylinder heads, with the cams operating directly onto the inlet valve, indirectly, through a short rocker arm, on the exhaust valve; this allows a light valvetrain to operate valves in a flat combustion chamber. The Unicam valve train was first used in single cylinder dirt bikes and has been used on the Honda VFR1200 since 2010. A dual overhead camshaft valvetrain layout is characterised by two camshafts located within the cylinder head, one operating the intake valves and the other one operating the exhaust valves; this design reduces valvetrain inertia more than is the case with an SOHC engine, since the rocker arms are reduced in size or eliminated. A DOHC design exhaust valves than in SOHC engines; this can give a less restricted airflow at higher engine speeds. DOHC with a multivalve design allows for the optimum placement of the spark plug, which in turn improves combustion efficiency.
Engines having more than one bank of cylinders with two camshafts in total remain SOHC and "twin cam" unless each cylinder bank has two camshafts. Although the term "twin cam" is used to refer to DOHC engines, it is imprecise, as it includes designs with two block-mounted camshafts. Examples include the Harley-Davidson Twin Cam engine, Riley car engines from 1926 to the mid 1950s, Triumph motorcycle parallel-twins from the 1930s to the 1980s, Indian Chief and Scout V-twins from 1920 to the 1950s; the terms "multivalve" and "DOHC" do not refer to the same thing: not all multivalve engines are DOHC and not all DOHC engines are multivalve. Examples of DOHC engines with two valves per cylinder include the Alfa Romeo Twin Cam engine, the Jaguar XK6 engine and the Lotus Ford Twin Cam engine. Most recent DOHC engines are multivalve, with between five valves per cylinder. More than two overhead camshafts are not known to have been tried in a production engine. However, MotoCzysz has designed a motorcycle engine with a triple overhead camshaft configuration, with the intake ports descending through the cylind
Alfa Romeo Alfetta
The Alfa Romeo Alfetta is a front-engine, five-passenger sedan and fastback coupé manufactured and marketed by Alfa Romeo from 1972-1987 with a production total over 400,000. The Alfetta was noted for the rear position of its transaxle and its De Dion tube rear suspension — an arrangement designed to optimize handling by balancing front/rear weight distribution, as well as maintaining a low polar moment of inertia and low center of gravity; the interior of Coupé models featured a unusual central tachometer placement — by itself, directly in front of the driver. The Alfetta name, which means "little Alfa" in Italian, derived from the nickname of the Alfa Romeo Tipo 159 Alfetta, a successful Formula One car which in its last iteration paired a transaxle layout to De Dion tube rear suspension — like its modern namesake; the Alfetta introduced a new drivetrain layout to the marque. Clutch and transmission were housed at the rear of the car, together with the differential for a more balanced weight distribution, as used on the Alfetta 158/159 Grand Prix cars.
The suspension relied on double wishbones and torsion bars at the front and a De Dion tube at the rear. When leaving the factory all Alfettas fitted Pirelli Cinturato 165HR14 tyres; the rear de Dion transaxle found on the Alfetta and derivatives- GTV, 90 and 75- provided these cars with excellent weight distribution. The handling advantages were noted in contemporary reviews; the transaxle design, in combination with a Watt's parallelogram linkage, inboard rear brakes and a well-located de Dion rear suspension, resulted in balanced traction and handling. The front suspension design was unusual in that it incorporated independent longitudinal torsion bar springs acting directly onto the lower wishbones and with separate dampers; the Alfetta saloon was launched in 1972, with a 1.8-litre four-cylinder as a three-box, four-door, five-passenger notchback saloon designed in-house by Centro Stile Alfa Romeo. The front end was characterised by twin, equal-sized headlamps visually connected to a central narrow Alfa Romeo shield by three chrome bars, while the tail lights featured three square elements.
At the 1975 Brussels Motor Show Alfa Romeo introduced the 1,594 cc, 108 PS Alfetta 1.6 base model, distinguished by its single, larger round front headlights. Meanwhile, the 1.8-litre Alfetta was rebadged Alfetta 1.8 and a few months mildly restyled, further set apart from the 1.6 by a new grille with a wider central shield and horizontal chrome bars. Engines in both models were Alfa Romeo Twin Cams, with two overhead camshafts, 8-valves and two double-barrel carburettors. Two years the 1.6 was upgraded to the exterior and interior features of the 1.8. In 1977 a 2.0-litre model was added. Launched at the March Geneva Motor Show, the Alfetta 2000 replaced the outgoing Alfa Romeo 2000; this range-topping Alfetta was 10.5 cm longer than the others, owing to a redesigned front end with square headlights and to larger bumpers with polyurethane inserts. Just a year in July 1978, the two-litre model was updated becoming the Alfetta 2000 L. Engine output rose from 122 PS to 130 PS; the Alfetta 2000 was marketed as the Alfa Romeo Sport Sedan in the United States, where "Alfetta" had less recognition than Europe.
The 2000 received fuel injection in 1979. A turbodiesel version was introduced in late 1979, the Alfetta Turbo D, whose engine was supplied by VM Motori. Apart from a boot lid badge, the Turbo D was equipped and finished like the top-of-the-line 2000 L both outside and inside. Therefore, it received a tachometer, but no standard power steering, despite additional 100 kg carried by the front axle; the turbodiesel, a first on an Alfa Romeo's passenger car, was of 2.0 litres and produced 82 PS. The Alfetta Turbo D was marketed in Italy and in France, as well as a few other continental European markets with a favorable tax structure. In 1981 Alfa Romeo developed in collaboration with the University of Genoa a semi-experimental Alfetta version, fitted with a modular variable displacement engine and an electronic engine control unit. Called Alfetta CEM, it was shown at the Frankfurt Motor Show; the 130 PS 2.0-litre modular engine featured fuel injection and ignition systems governed by an engine control unit, which could shut off two of four cylinders as needed in order to reduce fuel consumption.
An initial batch of ten examples were assigned to taxi drivers in Milan, to verify operation and performance in real-world situations. According to Alfa Romeo during these tests cylinder deactivation was found to reduce fuel consumption by 12% in comparison to a CEM fuel-injected engine without variable displacement, by 25% in comparison to the regular production carburetted 2.0-litre. After the first trial, in 1983 a small series of 1000 examples was put on sale, offered to selected clients. Despite this second experimental phase, the project development ended. Fuel injected, US-specification versions of the Alfetta were sold as limited editions in some European countries. In November 1981 the updated "Alfetta'82" range was launched, comprising 1.6, 1.8, 2.0 and 2.0 Turbo Diesel models. All variants adopted the interior of the 2.0-litre models. All Alfettas had black plastic rubbing strips, side sill mouldings
