88-498: The Alfa Romeo Alfetta (Type 116) is a front-engine, five-passenger saloon and fastback coupé manufactured and marketed by Italian automaker Alfa Romeo from 1972 to 1987 with a total over 400,000 units produced during its production run. The Alfetta was noted for the rear position of its transaxle (clutch and transmission) and its De Dion tube rear suspension — an arrangement designed to optimize handling by balancing front/rear weight distribution, as well as maintaining
176-514: A KKK turbocharger which pushed power up to 175 PS (129 kW; 173 hp). The car also received a modified suspension layout. This was the first Italian petrol production car with a turbocharger. The styling of the GTV, while distinctive, can be seen to share many design features derived from the Montreal , as translated down to a simpler and thus more marketable vehicle. Examples of this are
264-457: A transaxle layout to De Dion tube rear suspension — like its modern namesake. The Alfetta introduced a new drivetrain layout to the marque. The 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
352-530: 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 (4.1 in) longer than other models, owing to a redesigned front end with rectangular headlights and larger bumpers with polyurethane inserts; the rectangular tail light clusters and C-pillar vents were revised, as were
440-577: A 3.0-litre V8 engine, derived from the 2.6-litre V8 of the Montreal coupé and sharing the same mechanical fuel injection by SPICA . This version was driven by Ballestrieri in the relatively minor Valli Piacentine Rally, but development of the V8 Alfetta as a competition machine was not pursued when the plan to produce 400 roadgoing units of this model for homologation was abandoned. Around twenty 2.6-litre V8-engined Alfetta GTVs were built by Autodelta at
528-672: A black leather interior; and came with "Maratona" badging on the rear decklid, front fenders and glove box door. (The most notable feature of the Maratona, its aerodynamic kit, was also available as a dealer-installed option on other GTV-6 models.) Callaway Cars , famous for their later Camaro , Impala SS and Corvette offerings, modified between thirty and thirty six (depending on whether one "counts" those cars with Callaway components which were not assembled by Callaway but, instead, had those components fitted by Alfa Romeo dealers) twin-turbocharged GTV-6s between 1983 and 1986. These are called
616-581: A diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler . Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Diesel engines are typically well suited to turbocharging due to two factors: As per turbocharged petrol engines, an intercooler can be used to cool
704-740: A five-cylinder intercooled turbo-diesel engine in the 1976 Mercedes-Benz C111-IID experimental vehicle. The first turbo-diesel production car was the Mercedes-Benz 300SD (W116) saloon, which was sold in the United States from mid-1978 and powered by the OM617 five-cylinder engine. A year later, the Peugeot 604 D Turbo became the first turbo-diesel car to be sold in Europe. Turbo-diesel cars began to be widely built and sold in Europe during

A sedan is typically considered to be a fixed-roof car with at least four seats. Based on this definition, the earliest sedan was the 1911 Speedwell , which was manufactured in the United States. In American English , Latin American Spanish , and Brazilian Portuguese ,
880-679: A four-door station wagon from 1958 until 1960 in the Rambler and Ambassador series. In 1973, the US government passed Federal Motor Vehicle Safety Standard 216 creating a standard roof strength test to measure the integrity of roof structure in motor vehicles to come into effect some years later. Hardtop sedan body style production ended with the 1978 Chrysler Newport . Roofs were covered with vinyl, and B-pillars were minimized by styling methods like matt black finishes. Stylists and engineers soon developed more subtle solutions. A close-coupled sedan
968-472: A given speed depending on the exact use. Naturally aspirated Diesels, almost without exception, have a lower power output than a petrol engine of the same capacity whilst the same time requiring stronger (and thus heavier) internal components such as the pistons and crankshaft to withstand the greater stresses of the Diesel engine's much higher compression ratio . These factors give naturally aspirated Diesels

#17327721997881056-551: A horizontal trunk lid. The term is generally only referred to in marketing when it is necessary to differentiate between two sedan body styles (e.g., notchback and fastback) of the same model range. Several sedans have a fastback profile but a hatchback-style tailgate is hinged at the roof. Examples include the Peugeot 309 , Škoda Octavia , Hyundai Elantra XD , Chevrolet Malibu Maxx , BMW 4 Series Grand Coupe , Audi A5 Sportback , and Tesla Model S . The names hatchback and sedan are often used to differentiate between body styles of
1144-527: A low polar moment of inertia and low center of gravity. The interior of Coupé models featured a then unusual central tachometer placement — by itself, directly in front of the driver. The Alfetta name, which means "little Alfa" in Italian is derived from the nickname of the Alfa Romeo Alfetta (Tipo 159) , a successful Formula One car which in its last iteration introduced in 1951, paired

A sedan chair, a sophisticated litter , is an enclosed box with windows used to transport one seated person. Porters at the front and rear carry
1320-420: A poor power-to-weight ratio. Turbocharger units weigh very little but can offer significant power, torque, and efficiency improvements. Fitting a turbocharger can bring a Diesel engine's power-to-weight ratio up to the same level as an equivalent petrol unit, making turbodiesels desirable for automotive use, where manufacturers aim for comparable power outputs and handling qualities across their range, regardless of
1408-488: A production run of only 350 cars. The Balocco was available only in red colour with a sunroof and black interior, leather-wrapped steering wheel and red piping on the seats. There were also two green Quadrifoglio badges fixed on the rear quarter trim pieces above a badge with the "Balocco SE" designation. It was similar to the European-market "Grand Prix" special edition. A plaque inset in the glove box door designated
1496-574: A railroad train's club carriage (e.g.,, the lounge or parlour carriage). From the 1910s to the 1950s, several United States manufacturers have named models either Sedanet or Sedanette. The term originated as a smaller version of the sedan; however, it has also been used for convertibles and fastback coupes. Models that have been called Sedanet or Sedanette include the 1917 Dort Sedanet, King , 1919 Lexington , 1930s Cadillac Fleetwood Sedanette, 1949 Cadillac Series 62 Sedanette, 1942-1951 Buick Super Sedanet , and 1956 Studebaker . Sedans, as
1584-623: A remarkable second place overall at the 24 Hours Spa , as well as an overall win in the ETC race at Vallelunga , in the 500 Kilometres of Vallelunga. Despite such results, Autodelta's efforts with the Group 2 Alfetta were desultory and ended prematurely, due to Alfa's budgetary constraints and heavy commitments to Formula One and the World Championship for Sports Cars . At the end of the 1975 season, Autodelta also rallied an Alfetta GTV with
1672-542: A somewhat revised suspension (most notably eschewing the metric Michelin TRX wheel/tire combination—then standard on the GTV-6, in favor of Pirelli or Goodyear tires on conventionally sized BBS , Speedline, or OZ lightweight alloys), improved brakes and, most importantly, a twin-turbocharger system, boosting performance to exotic levels. Power is 230 hp (172 kW; 233 PS) at 5,500 rpm; up by fifty percent over

Their compact and fuel-efficient nature has made them a preferred choice for urban and suburban settings, promoting individual mobility. However, this accessibility has contributed to increased urban sprawl and car dependency. Sedans, like other private vehicles, encourage dispersed living patterns, reducing
1848-548: 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 engine as a three-box , four-door, five-passenger notchback design (" Berlina " in Italian) penned in-house by Centro Stile Alfa Romeo. The front end

#17327721997881936-599: Is 2,934 cc, with bore and stroke both increased to 93 mm × 72 mm (3.66 in × 2.83 in). The fuel injection was replaced by six Dell'Orto carburettors (as used on the Alfa 6), as the aim was low-end torque rather than peak power. Power increased to 136.7 kW (185.9 PS; 183.3 hp) at 6,700 rpm. The gearing was lowered but the 3.0 still reached a higher top speed of 224.2 km/h (139.3 mph). Acceleration times are 8.36 seconds from 0–100 km/h and 7.2 seconds for 0–60 mph. On

Like other close-coupled body styles, the rear seats are farther forward than a regular sedan. This reduced the length of the body; close-coupled sedans, also known as town sedans, were the shortest of the sedan models offered. Models of close-coupled sedans include
2112-463: Is called Limousine and a limousine is a Stretch-Limousine . In the United States, two-door sedan models were marketed as Tudor in the Ford Model A (1927–1931) series. Automakers use different terms to differentiate their products and for Ford's sedan body styles "the tudor (2-door) and fordor (4-door) were marketing terms designed to stick in the minds of the public." Ford continued to use
2200-851: The BMW 535i , with a 3.5-litre engine, a new 3-litre variant of the V6 engine was installed. It won its debut race in the Lodge Group One International two-hour race at Kyalami 1983 and after that it took 1st and 2nd place in the Group One class of the Castrol three-hour race at Killarney and Index victory at the World Endurance Championship 1000 km Race at Kyalami in December 1983.

A Coach body has no external trunk for luggage. Haajanen says it can be difficult to tell the difference between a Club and a Brougham and a Coach body, as if manufacturers were more concerned with marketing their product than adhering to strict body style definitions. Close-coupled saloons originated as four-door thoroughbred sporting horse-drawn carriages with little room for rear passengers' feet. In automotive use, manufacturers in

The GTV 6 3.0 was billed as the most powerful production sports car ever built by Alfa Romeo. The car was a co-operative effort by Alfa Romeo South Africa and Autodelta . It was developed mainly for racing, so only 200 had to be built for homologation. To compete with
3256-541: The Alfa Romeo triangular grille was changed to matte-black trim. The 1.6-litre version was discontinued and the Alfetta GTV became known simply as Alfa Romeo GTV 2.0 ; the Alfetta name was dropped, but the two-litre coupé retained its type designation of 116.36 for left-hand drive and 116.37 for right-hand drive. 15-inch disc-shaped alloy wheels and Pirelli Cinturato CN36 tyres were now standard, as opposed to
3344-420: The Alfetta received its third and final facelift ; the exterior was modernised with newly designed bumpers (integrating a front spoiler and extending to the wheel openings), a new grille, lower body plastic cladding, silver hubcaps and, at the rear, a full width grey plastic fascia supporting rectangular tail lights with ribbed lenses and the number plate. The C-pillar ventilation outlets were moved to each side of
3432-600: The Alfetta were sold as limited editions in some European countries; one example was the 1981 Alfetta LI America for the Italian market, based on the North American Sport Sedan. 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 bodyshell and interior of the 2.0-litre models; standard equipment became richer. All models in this range had black plastic rubbing strips, side sill mouldings, tail light surround and hubcaps;

This was possible because of the advanced turbocharger design, comprising a five-stage axial compressor combined with a nine-stage radial compressor and an intercooler. Use of turbo-diesel engines in road-going vehicles began with trucks in
3784-473: The Tudor name for 5-window coupes, 2-door convertibles, and roadsters since all had two doors. The Tudor name was also used to describe the Škoda 1101/1102 introduced in 1946. The public popularized the name for a two-door model and was then applied by the automaker to the entire line that included a four-door sedan and station wagon versions. In the United States, the notchback sedan distinguishes models with
3872-462: The United Kingdom used the term to develop the chummy body, where passengers were forced to be friendly because they were tightly packed. They provided weather protection for extra passengers in what would otherwise be a two-seater car. Two-door versions would be described in the United States and France as coach bodies. A postwar example is the Rover 3 Litre Coupé . Produced in the United States from
3960-435: The beginning of modern turbocharging technology. By the late 1920s, several manufacturers were producing large turbo-diesels for marine and stationary use, such as Sulzer Bros., MAN, Daimler-Benz, and Paxman. Subsequent improvements in technology made feasible the use of turbochargers on smaller engines that ran at higher engine speeds, so turbo-diesel locomotive engines began appearing in the late 1940s. In 1951, MAN built

The door shape is similar, and in a sharing of parts, both vehicles employ the same door handles. In 1980, the GT received a restyling. Outside there were new one-piece taillights, grey plastic bumpers, C-pillar vents and side skirts; all bright stainless steel save for
4136-562: The carburetted 2.0, while developing more torque and being more fuel efficient. In April 1984 the successor of the Alfetta debuted, the larger Alfa Romeo 90 . At the end of the year the Alfetta Berlina went out of production, after nearly 450,000 had been made over a 12-year production period. The Alfa Romeo Alfetta was used as police car by the Carabinieri as well as by Polizia di Stato . It became well known throughout
4224-526: The chair with horizontal poles. Litters date back to long before ancient Egypt, India, and China. Sedan chairs were developed in the 1630s. Etymologists suggest the name of the chair very probably came through varieties of Italian from the Latin sedere , or the Proto-Indo-European root " sed- " meaning "to sit." The first recorded use of sedan for an automobile body occurred in 1912 when
4312-625: The dash, steering wheel and upholstery. Just a year later, in July 1978, the two-litre model was updated becoming the Alfetta 2000 L . Engine output rose from 122 PS (90 kW; 120 hp) to 130 PS (96 kW; 128 hp); with revised upholstery and simulated wood dash. The Alfetta 2000 was marketed as the Alfa Romeo Sport Sedan in the United States, where "Alfetta" name had less recognition than Europe. The 2000 received fuel injection in 1979. A turbodiesel version
4400-482: The density of communities and limiting opportunities for local social interactions. This can lead to a decline in neighborhood growth and an increase in reliance on cars for even short trips, increasing environmental and health concerns through CO2 and Greenhouse Gas emissions and reduced physical activity . Furthermore, while sedans are a practical solution for families and individuals, their role in encouraging road-centric urban planning has been criticized for reducing

Later in the same year, the GTV ;6 2.5 , a version of the GTV with the SOHC 2.5 L V6 engine from the Alfa Romeo Alfa 6 luxury saloon, was released. As a result, the hood received a bulge to clear the top of the intake and became its most pronounced feature.

The Volvo Titan Turbo truck was also introduced in 1954. By the late 1960s, demand for increasingly powerful truck engines led to turbo-diesels being produced by Cummins , Detroit Diesel , Scania AB , and Caterpillar Inc . In 1952, the Cummins Diesel Special became

The fuel injected engine was also able to meet the strict emissions standards introduced in Switzerland (shared with Sweden) for 1983. The V6 received rave reviews from the motoring press, which had previously lambasted the same engine in the Alfa 6 because of the carburettor problems. The fuel injection eventually made it into

Racing versions of the Alfetta GT and GTV were built by Autodelta , initially with the naturally aspirated engines from the earlier GTAm racer based on the 105 series coupé, for homologation under FIA Group 2 . There were some variations ranging from the Alfetta GT 1,800 cc engines with twin-plug or even 16-valve heads up to

In 1986 production of the GTV ;6 ceased and Alfa Romeo turned its Group A racing and rallying efforts to the 75/Milano saloons, which were based on the same rear transaxle chassis. However, 1986 also saw the GTV 6 post one of its finest rallying victories when Yves Loubet 's example won the Group A in the tragic 1986 Tour de Corse and placed 3rd overall among

The car was powered by a 6.6 L (403 cu in) inline-six engine producing 283 kW (380 hp). Research into smaller turbo-diesel engines for passenger cars was undertaken by several companies through the 1960s and 1970s. Rover built a prototype 2.5 L four-cylinder turbo-diesel in 1963, and Mercedes-Benz used

#17327721997885456-454: The last decade have spurred their widespread adoption in certain markets, notably in Europe where they (as of 2014) make up over 50% of new car registrations. Turbodiesels are generally considered more flexible for automotive uses than naturally aspirated Diesel engines. Turbodiesels can be designed to have a more acceptable spread of torque over their speed range or, if being built for commercial use, can be designed to improve torque output at
5544-423: The late 1980s and early 1990s, a trend that has continued to the present day. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping, due to better specific power and better exhaust-emission behaviour of turbocharged engines with a lower compression ratio. Indirect injected engines used to have compression ratios of 18.5 or higher. Following the introduction of common rail engines in
5632-548: The late 1990s, compression ratios decreased to the range of 16.5 to 18.5. Some diesel engines built since 2016 to comply with the Euro 6 exhaust emissions regulations have a compression ratio of 14.0. Turbocharging can greatly increase the power output of a diesel engine, bringing the peak power-to-weight ratio closer to that of an equivalent petrol engine. Improvements in power, fuel economy, and noise, vibration, and harshness in both small- and large-capacity turbodiesels over

Some people describe a club sedan as a two-door vehicle with a body style otherwise identical to the sedan models in the range. Others describe a club sedan as having either two or four doors and a shorter roof and therefore less interior space than the other sedan models in the range. Club sedan originates from

The Maratona model included a more aggressive aerodynamic trim package, lightweight Speedline wheels, clear engine view port, sunroof, wood steering wheel and shift knob, rear louvers and Carello fog lamps. All 150 cars were available only painted silver and with
5984-766: The outside, the different induction system of the GTV6 3.0 required a new fiberglass bonnet with a prominent bulge. In the US market, the four-cylinder coupé was available from 1975 to 1977 under the moniker Alfetta GT , renamed the Sprint Veloce for the final two years of availability in 1978 and 1979. The Sprint Veloce received an engine upgrade as Alfa Romeo were coming to grips with the American emissions regulations, with power increased marginally to 111 hp (83 kW; 113 PS) at 5,000 rpm from 110 hp (82 kW; 112 PS) at 5,500 rpm. The engine
6072-605: The powerful 2-litre GTAm engine. In this form they were rallied with moderate success in 1975, winning the Elba and Costa Brava rallies overall, as well as winning the Group 2 category in the World Rally Championship's Corsican event. The next year Autodelta shifted its focus to circuit racing the Alfettas, which won the under 2.5-liter Group 2 division of the European Touring Car Championship , scoring
6160-419: The rear window. Inside there were a redesigned dashboard and instrumentation, new door panels and the check control panel from the Quadrifoglio Oro on all models. Top of the range models adopted an overhead console, which extended for the full length of the roof and housed three reading spot lamps, a central ceiling light, and controls for the electric windows. Alongside the facelift two new models were introduced:
6248-811: The request of the German Alfa importer in 1977, where they were sold for DM 50,000, considerably more than the DM20,990 charged for an Alfetta GTV2000. In 1980 the Alfetta GTV Turbodelta was already homologated in FIA Group 4 , since the required number of production engines had been built and fitted to Alfetta Turbodelta Stradale and Nuova Giulietta Turbodelta models. A racing version was campaigned in rallies and developed during 1979 and 1980 seasons: entries backed by Jolly Club were driven by Pregliasco, Ormezzano and Verini. The last development of
6336-429: The same model. To avoid confusion, the term hatchback sedan is not often used. There have been many sedans with a fastback style. Hardtop sedans were a popular body style in the United States from the 1950s to the 1970s. Hardtops are manufactured without a B-pillar leaving uninterrupted open space or, when closed, glass along the side of the vehicle. The top was intended to look like a convertible's top. However, it
6424-444: The second series of the Alfa 6 as well. The GTV went through a number of revisions, including new gear ratios and an updated interior in 1984. The GTV 6 was also a fairly successful racing car; the 116 type chassis developed for racing since its first outing in the 1974 San Martino di Castrozza rallye. The racing successes included winning the European Touring Car Championship an unprecedented four years in succession (1982–85),
6512-500: The term sedan is used (accented as sedán in Spanish). In British English , a car of this configuration is called a saloon ( / s ə ˈ l u n / ). Hatchback sedans are known simply as hatchbacks (not hatchback saloons ); long-wheelbase luxury saloons with a division between the driver and passengers are limousines . In Australia and New Zealand , sedan is now predominantly used; they were previously simply cars. In
6600-546: The typical characteristics of sedans are: It is sometimes suggested that sedans must have four doors (to provide a simple distinction between sedans and two-door coupés ); others state that a sedan can have four or two doors. Although the sloping rear roofline defined the coupe, the design element has become common on many body styles with manufacturers increasingly "cross-pollinating" the style so that terms such as sedan and coupé have been loosely interpreted as "'four-door coupes' - an inherent contradiction in terms." When
6688-452: The viability of public transportation and active transport modes like walking and cycling. In cities heavily dependent on sedans, air pollution, noise, and traffic fatalities often increase, posing public health risks and environmental challenges . Turbodiesel The term turbo-diesel , also written as turbodiesel and turbo diesel , refers to any diesel engine equipped with a turbocharger . As with other engine types, turbocharging
6776-574: The world since it was Italian former Prime Minister Aldo Moro 's official escort car when he was kidnapped by the Red Brigades . South African models were first assembled at the Rosslyn manufacturing plant located outside Pretoria . These early 1973 models were manufactured alongside Datsuns. From 1974 South African Alfettas were manufactured at Alfa Romeo's own Brits plant. The 1600 model, with single headlamps as in Europe, arrived to complement
6864-536: Was catalyzed and had a new intake manifold, based on alterations originally developed for California-market cars. It was one of Road & Track's 10 Best Cars For a Changed World . Finally, the V6 version was marketed from 1981 to 1986 as the GTV-6 . For the US market, two limited production GTV-6 models stand out. The GTV6 Balocco (named after the famous Alfa Romeo's Balocco test track in Italy) introduced in 1982 with
6952-414: Was characterised by twin, equal-sized headlamps visually connected to a central narrow Alfa Romeo shield by three chrome bars, while the taillights featured three square elements. At the 1975 Brussels Motor Show Alfa Romeo introduced the 1,594 cc (97 cu in), 108 PS (DIN) Alfetta 1.6 base model, distinguished by its single, larger round front headlamps. Meanwhile, the 1.8-litre Alfetta
7040-642: Was distinguished from the 1.6 version by twin chrome whiskers in the grille and GTV scripts carved in the ventilation vents on the C-pillar . In 1979, some minor revisions, including a revised engine with new camshaft profiles and a change to mechanical-and-vacuum ignition advance, saw the 2.0-litre redesignated the Alfetta GTV ;2000L. Autodelta also introduced a limited edition 2.0-litre turbocharged model, named Turbodelta , of which 400 were made for FIA Group 4 homologation . This version used
7128-543: Was fixed and made of hard material that did not fold. All manufacturers in the United States from the early 1950s into the 1970s provided at least a 2-door hardtop model in their range and a 4-door hardtop. The lack of side bracing demanded a strong, heavy chassis frame to combat unavoidable flexing. The pillarless design was also available in four-door models using unibody construction. For example, Chrysler moved to unibody designs for most of its models in 1960 and American Motors Corporation offered four-door sedans, as well
7216-473: Was found to reduce fuel consumption by 12% in comparison to a CEM fuel-injected engine without variable displacement, and almost by 25% in comparison to the regular production carburetted 2.0-litre engines. In 1983 after the first trial, a small series of 1,000 examples was put on sale, offered to selected clients; 991 examples were ultimately produced. Despite this second experimental phase, the project development ended. Fuel injected, US-specification versions of
7304-408: Was gearing up to assemble them, 100 fully built-up cars were brought in from Italy. These received a numbered plaque on the front wheel arch, just ahead of the door. South Africa was one of two markets to have a turbocharged GTV 6, with a Garrett turbocharger and a NACA intake. An estimated 750 were assembled before all local Alfa production ceased in 1986. The South African market also introduced
7392-552: Was introduced in 1985 in some European markets (most notably Switzerland and Germany). It featured a body kit designed by Rayton Fissore . A GTV 6 was driven to victory by Greg Carr and Fred Gocentas in the 1987 Australian Rally Championship . South African models were first assembled at the Rosslyn manufacturing plant, located outside Pretoria . These early 1973 models were manufactured alongside Datsuns. From 1974 South African Alfettas were manufactured at Alfa Romeo's own Brits plant. The GTV6 2.5 arrived in 1982; while Brits
7480-632: 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 an additional 100 kg (220 lb) carried by the front axle. The turbodiesel engine, a first on an Alfa Romeo's passenger car, displaced 2.0 litres and produced 82 PS (60 kW; 81 hp). The Alfetta Turbo D
7568-567: Was marketed mostly in Italy and in France, as well as a few other continental European markets with a favorable tax structure. In 1981, Alfa Romeo developed a semi-experimental Alfetta model in collaboration with the University of Genoa , fitted with a modular variable displacement engine and an electronic engine control unit . This model was called the Alfetta CEM ( Controllo Elettronico del Motore , or Electronic Engine Management), it
7656-455: Was rebadged Alfetta 1.8 and a few months later 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 later the 1.6 was upgraded to the exterior and interior features of the 1.8 model. In 1977
7744-611: Was shown at the Frankfurt Motor Show . The 130 PS (96 kW; 128 bhp) 2.0-litre modular engine featured fuel injection and ignition systems governed by an engine control unit, which could shut off two out 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
