72-656: The Chevette employed General Motors' global T platform which was co-developed by Opel and Isuzu in 1973. The first T-car model produced was the Brazilian Chevrolet Chevette released in the same year. Six months later the Opel Kadett C was released in Europe. Worldwide, GM manufactured and marketed more than 7 million T-cars – either as rebadged models or locally-built versions in different countries. T-car variants were sold internationally as

144-400: A secondary imbalance . This is caused by the acceleration/deceleration of the pistons during the top half of the crankshaft rotation being greater than that of the pistons in the bottom half of the crankshaft rotation (because the connecting rods are not infinitely long). As a result, two pistons are always accelerating faster in one direction, while the other two are accelerating more slowly in

216-706: A 1.6-liter (98 cu in) engine in lieu of the 1.4-liter (85 cu in) overhead-cam four-cylinder, rated at 60 hp (45 kW) instead of 52 hp (39 kW), along with a rear stabilizer and special body graphics. The Chevette Woody (1976) featured simulated wood-grain siding and upgraded interior and exterior trim. The Scooter was offered as a base model with a $ 2,899 suggested retail price (equivalent to $ 15,500 in 2023), two front passenger seats, an optional rear seat, deletion of most exterior chrome (e.g., window surrounds), painted rather than chrome bumpers, an open glove box, black carpeting, door-pull straps in lieu of arm rests, fiberboard door panels, and

288-773: A Chevrolet dealer in Springdale, Ohio. The T-car had been launched internationally in Brazil under the Chevette name in 1973, as a two-door sedan and ultimately a four-door sedan, a two-door hatchback , and a two-door station wagon (named Marajó ), as well as a utility (named the Chevy 500 ), produced until 1994. The origin of the Chevette Engine has been long debated. Many reference Italian coffee table book Tutte le Auto del Mondo 1985, p. 187 and p189 . from

360-662: A chrome "Bright Package". Front seats featured inertia locking mechanisms that enabled entry and exit adjustment of the front seatback without using a separate release. Pontiac marketed a rebadged variant in Canada as the "Acadian". In addition to being the smallest, most fuel-efficient car marketed by Chevrolet, the Chevette was the lightest car marketed in the U.S. The EPA rated the base 1.4-liter engine at 28 miles per US gallon (8.4 L/100 km; 34 mpg ‑imp ) city and 40 miles per US gallon (5.9 L/100 km; 48 mpg ‑imp ) highway. Chevrolet claimed that

432-451: A cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occurring at certain times. Compared with a V4 engine or a flat-four engine , a straight-four engine only has one cylinder head , which reduces complexity and production cost. Petrol straight-four engines used in modern production cars typically have a displacement of 1.3–2.5 L (79–153 cu in), but larger engines have been used in

504-600: A displacement of 1.5–2.5 L (92–153 cu in). The smallest automotive straight-four engine was used in the 1963–1967 Honda T360 kei truck and has a displacement of 356 cc (21.7 cu in), while the largest mass-produced straight-four car engine is the 1999–2019 Mitsubishi 4M41 diesel engine which was used in the Mitsubishi Pajero and has a displacement of 3.2 L (195 cu in). Significant straight-four car engines include: Many early racing cars used straight-four engines, however

576-536: A few more years in Ecuador and Colombia. The Chevette originally appeared with a 1.4-liter single overhead cam inline-four. In 1981 this was augmented by a locally developed 1.6-liter version, it too with a single carburetor. The Brazilian 1.4 and 1.6 were similar to but not the same as the EPA compliant North American 1.4 and 1.6. For 1988, the 1.6 gained a twin-carb setup and now produced 78 PS (57 kW) rather than

648-454: A lower hanging dashboard, automatic seatbelts, and a center-dash console. Chevette sales totaled more than 451,000 units – a figure that would rank it second only to Chevrolet's new Citation , which had a much longer model run (sales had started in April 1979). Consumer Guide testers managed "an honest 29 mpg in the city and 39 mpg on the highway". The 1980 rear fascia was revised with

720-517: A passenger seat without fore-aft adjustment. A total of 9,810 Scooter models were manufactured, compared to 178,007 regular hatchbacks. In 1977, the engines offered were 57 hp (43 kW) and 63 hp (47 kW). The Scooter hatchback included a rear seat, while offering a rear-seat delete option. The Sandpiper trim package included a “reef”-patterned interior, deluxe door trim, cream gold or antique white exterior colors, and an exterior Sandpiper logo just behind each door. In 1978, models had

792-572: A rebadged Chevette, received all the T1000's Pontiac-exclusive features from this point on. Chevrolet sold 433,000 Chevettes in 1981 and 233,000 in 1982. In 1983, the Chevettes had a makeover for the front and rear fasciae, and the Chevette CS was introduced. A black-finished grille and trim moldings replaced most chrome pieces. Scooter and base Chevettes featured black bumpers and end caps, while

864-424: A revised grille with a grid design, while the grille and headlight frames were chromed for standard models, a four-door hatchback riding on a 97.3-inch (2,470 mm) wheelbase was added – two inches longer than the two-door – and this version accounted for more than half of the Chevette's nearly 300,000 sales. The 1.4-liter engine and Woody package were dropped with a fuel door added. A TH-180 automatic transmission

936-530: A squared-off hatch, wraparound taillights with combined, single-colored turn signals, and a round gas-filler door. In August 1981, a diesel engine option was new with a late 1981 availability – this is a 1.8-liter Isuzu unit only available coupled to an Isuzu five-speed. The 51 hp (38 kW) powertrain is the same as was installed in the Isuzu I-Mark . It was not available with air conditioning. New styled-steel wheels with center caps were offered, and

1008-630: A station wagon, as a pickup, or as a double-cab pickup. This replaced an earlier version (since 1976) which used bodywork based on that of the Vauxhall Viva , as well as Vauxhall mechanics. By 1980 the Vauxhall parts had become impossible to import and Grumett switched to Chevette parts from Brazil. The Grumett used the original 1.4-liter version of the Chevette engine. The regular Chevette was also assembled in Uruguay, by General Motors Uruguaya. It

1080-469: A straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four . Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. A four-stroke straight-four engine always has

1152-401: A time when regulations dictated a maximum displacement of 550 cc; the maximum size is currently at 660 cc. Straight-four engines with the preferred crankshaft configuration have perfect primary balance . This is because the pistons are moving in pairs, and one pair of pistons is always moving up at the same time as the other pair is moving down. However, straight-four engines have

1224-523: A top speed of 53 mph (85 km/h). A luxury variant of the Chevette, the Leata Cabalero, was manufactured and marketed for model years 1976 and 1977 by Stinebaugh Manufacturing Company, founded by Donald E. Stinebaugh (1916–1992) with his son Leonard D. "Sonny" Stinebaugh (1946–2001) in Post Falls, Idaho . Donald Stinebaugh named the car after his wife Hilda (Erickson) Stinebaugh, giving

1296-429: Is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When

1368-517: Is particularly beneficial in the higher rpm range, and " big-bang firing order " theory says the irregular delivery of torque to the rear tire makes sliding in the corners at racing speeds easier to control. Inline-four engines are also used in MotoGP by the Suzuki (since 2015 ) and Yamaha (since 2002 ) teams. In 2010 , when the four-stroke Moto2 class was introduced, the engines for the class were

1440-470: The Maserati 4CL and various English Racing Automobiles (ERA) models. These were resurrected after the war, and formed the foundation of what was later to become Formula One , although the straight-eight supercharged Alfettas would dominate the early years of F1. Another engine that played an important role in racing history is the straight-four Ferrari engine designed by Aurelio Lampredi . This engine

1512-474: The "check engine" light, and a new bowtie emblem on the front grille. In 1987, Chevrolet dropped the Chevette S model and the diesel engine option (after 324 were sold in 1986, plus 264 diesel-engined Pontiac 1000). These were the last North American market General Motors diesel passenger cars built for many decades, following the discontinuation of the Oldsmobile Diesel engine . The Chevette's price

1584-689: The 1.0 had a brief sales life. It only remained available until 1993, after which the Corsa took over. A 1.8-liter Isuzu diesel-engined version was also built in Uruguay, exclusively for the Uruguayan market. In the Brazilian market, both the 1.4 and the 1.6 were available in gasoline and alcohol versions. In Argentina, the Kadett C was originally marketed as the Opel K-180 , but between 1992 and 1995,

1656-484: The 1.0-litre "Chevette Junior" for early 1992. This used a narrow-bore, short-stroke 50 PS (37 kW) version of the OHC engine with a catalytic converter. The Junior did not do particularly well in the market, competing against the much more modern Fiat Uno Mille , Volkswagen Gol , and Ford Escort Hobby . Being rather underpowered and heavy at 865 kg (1,907 lb), with a top speed of 134 km/h (83 mph),

1728-473: The 1.6 was now also available to run on gasoól and a five-speed manual gearbox was available as an option. The Latin American Chevettes underwent a series of facelifts, in 1978, 1983, and a major one in 1987, which meant new headlights and a black plastic grille. Where available, the station wagon used the Chevette name outside of Brazil. The hatchback remained in production until 1988, while

1800-527: The 1.6-liter OHC inline four rated at 70 hp, this model continued in production until 1994, and was the last Chevette version built in Brazil, where it was replaced by the coupé utility version of Chevrolet Corsa . Created by Horacio Torrendell, a fibreglass-bodied version (actually based on the Vauxhall Chevette 's bodywork) called the Grumett was built in Uruguay. It was available either as

1872-533: The 1920s and early 1930s. The Miller engine evolved into the Offenhauser engine which had a highly successful spanning from the 1933 until 1981, including five straight victories at the Indianapolis 500 from 1971 to 1976. Many cars produced for the pre-WWII voiturette Grand Prix motor racing category used inline-four engine designs. 1.5 L supercharged engines found their way into cars such as

1944-441: The 1970s. Since then, the inline-four has become one of the most common engine configurations in street bikes. Outside of the cruiser category, the inline-four is the most common configuration because of its relatively high performance-to-cost ratio. All major Japanese motorcycle manufacturers offer motorcycles with inline-four engines, as do MV Agusta and BMW . BMW's earlier inline-four motorcycles were mounted horizontally along

2016-469: The 2.4 litre Citroën DS engine, the 2.6 litre Austin-Healey 100 engine, the 3.3 L Ford Model A (1927) engine and the 2.5 L GM Iron Duke engine . Soviet/Russian GAZ Volga and UAZ engines with displacements of up to 2.9 litres were produced without balance shafts from the 1950s to the 1990s, however these were relatively low-revving engines which reduces the need for a balance shaft system. Most modern straight-four engines used in cars have

2088-402: The 72 PS (53 kW) in earlier version. This engine remained available until the end of Brazilian Chevette production. The lower-powered 1.4 was only available for gasohol as of 1981 and was discontinued entirely after 1982. A gasohol-powered version of the 1.6 appeared in its stead for 1983. As a tax cut for sub-1-liter cars appeared in late 1990, General Motors do Brasil responded with

2160-510: The Chevette as “unimaginative to an extreme.” Under the direction of chief engineer John Mowrey, Chevrolet began developing the Chevette on December 24, 1973. It was a response to the federal CAFE standards and the 1973 oil crisis . The Chevette was prompted by GM's Energy Task Force, which arose out of the crisis and the resultant shift in consumer demand to smaller, foreign vehicles boasting greater fuel efficiency. The Chevette used as its basis GM's World Car, Project 909–what would become

2232-433: The Chevette's turning circle (30.2 feet (9.2 m)) was one of the smallest in the world and that it was essentially a "metric" car, "international in design and heritage". The 1976–1978 Chevettes can be identified by round headlights. Chrome-rimmed, tricolor taillights were used from 1976 to 1979. Chevrolet marketed optional "Rally" and "Woody" packages, as well as the least expensive "Scooter" model. The Rally 1.6 included

2304-644: The Chevy (or GMC) 500 in Brazil and South America. A T-car variant remained in production in South America through 1998. Introduced on a full-color nationwide campaign in 140–150 of the country's largest daily papers, the New York Times said the "little American car holds its own with the foreigners." Looking back on the Chevette in 2011, the same publication called the Chevette "haphazardly made, sparsely trimmed and underpowered." Consumer Guide described

2376-493: The Holley two-barrel carburetor became standard on all models. The front fascia was revised with a flat hood, no longer wrapping down to the bumper. New for 1979 was a large chrome grille with Chevrolet's "bow-tie" emblem and rectangular headlights. A new air-injection system was introduced to improve catalytic-converter function at idle. An active passenger-restraint system was introduced in small numbers as an option which featured

2448-565: The Italian magazine Quattroruote .This book is cited as source for the majority of sites that give the same info. According to those who reference that book, the engine is either a 1.4L Isuzu G140 or 1.6L G161Z. And that the inline four Isuzu engine had its block cast in Brazil.

2520-619: The Marajó continued to be available until 1989. Marajó is an island located at the mouth of the Amazon River in Brazil. The four-door sedan version was built until 1989, mainly for export to other Latin American countries. The two-door sedan remained in production until 1993, only outlived by the pickup version ( Chevy 500 ), which continued until 1994 after having been first launched in 1983. The four-door sedan continued to be built for

2592-515: The Peugeot engine which won the 1913 Indianapolis 500 was a highly influential engine. Designed by Ernest Henry , this engine had double overhead camshafts (DOHC) with four valves per cylinder, a layout that would become the standard until today for racing inline-four engines. Amongst the engines inspired by the Peugeot design was the Miller engine , which was a successful racing engine through

2736-599: The T-car program, so named because the vehicles shared GM's T platform. With the well-known problems of its predecessor, the Vega , which included production issues, reliability problems, and a serious propensity for corrosion, the team reworked the international platform such that the Chevette shared not a single body panel with another T-car and reworked the underbody extensively to enhance corrosion protection. The Chevette's 1.4-liter base iron-block engine weighed 59 lb less than

2808-399: The T1000 (later, simply "1000") concurrently from 1981 to 1985. Power steering was a new option for the Chevette, as well as a 3.36 axle ratio (standard on T1000 models). The active passenger-restraint system was discontinued. New lighter-weight bucket seats were introduced that lacked much of the lower support of the heavier "panned" seats. A new adhesive-based, thinner windshield seal replaced

2880-475: The United States, Nimbus in Denmark, Windhoff in Germany, and Wilkinson in the United Kingdom. The first across-the-frame 4-cylinder motorcycle was the 1939 racer Gilera 500 Rondine , it also had double-over-head camshafts, forced-inducting supercharger and was liquid-cooled . Modern inline-four motorcycle engines first became popular with Honda 's SOHC CB750 introduced in 1969, and others followed in

2952-652: The Vega's much-heralded aluminum-block engine. The first North American Chevette, a two-door hatchback called the Chevette Scooter, rolled off the assembly line on August 18, 1975 and officially introduced on September 16, in Washington, DC, with the first models going on sale on October 2, just after new legislation-mandated Corporate Average Fuel Economy (CAFE) standards. With initial projected sales of 275,000 units in its first year, numbers were cut in half as

3024-627: The bigger-engined versions. About one quarter of the production was exported. The Chevrolet Chevy 500 was the coupé utility version of the Brazilian Chevette. Launched in 1983, it was the precursor to the Classic/ Corsa / Montana lineup of today. It competed with offerings from several other manufacturers, including the Fiat Fiorino , Ford Pampa , and Volkswagen Saveiro . Its payload was 500 kg (1,100 lb). Using

The Leata featured power windows, power seat and cruise control – as well as baroque styling with custom fiberglass body panels, round headlights in square bezels, a rectangular "classic" grille, and heavily styled fenders; 97 were made either in pickup or hatchback body styles. The Chevrolet Chevette

3168-414: The catalytic converter. A new catalytic converter was introduced with an air inlet for forced air injection from the air pump. A new one-piece cardboard-based headliner with an updated overhead dome light replaced the earlier vinyl liner. The Pontiac T1000 received a unique grille, body molding, and horizontal lined taillights, as well as an alloy sport wheel option. General Motors of Canada's Pontiac Acadian,

3240-413: The design and construction of the prototypes were entirely German. The engine was designed specifically for the Kadett C — our Chevette — and would complement a 1.2-liter OHV (in-block valve timing and overhead valves). The new engine was a 1.4-liter OHC (overhead valve control) and it was the first time that Opel used a timing belt to drive the control.″ and Buechler adds: ″The project for the new engine

3312-626: The equivalent of the Brazilian Chevette was sold there as the GMC Chevette . Production in Colombia, where a special version for taxi usage was also built, continued until 1998. The Chevette was the number-one seller in Chile for some time, last in 1991. The Chevette was made locally in Chile in 2-door and 4-door form from 1976 to 1983 while the Marajo station wagon was always imported from Brazil as

3384-471: The frame, but all current four-cylinder BMW motorcycles have transverse engines . The modern Triumph company has offered inline-four-powered motorcycles, though they were discontinued in favour of triples . The 2009 Yamaha R1 has an inline-four engine that does not fire at even intervals of 180°. Instead, it uses a crossplane crankshaft that prevents the pistons from simultaneously reaching top dead centre. This results in better secondary balance , which

3456-468: The higher-end Chevette CS models included color-keyed bumpers and caps with chrome bumper inserts as an option. Scooter and base models featured a black-only grille and headlight buckets, while CS models featured argent-colored trim. The Chevette S model introduced a cosmetic package that included black-painted styled-steel wheels and a red-accented grille and moldings, as well as oversized decal emblems in red. Front bucket seats featured new adjustable knobs on

3528-567: The large 2,495 cc FPF that won the Formula One championship in Cooper 's chassis in 1959 and 1960. In Formula One, the 1980s were dominated by the 1,500 cc turbocharged cars. The BMW M12/13 engine was notable for the era for its high boost pressures and performance. The cast iron block was based on a standard road car block and powered the F1 cars of Brabham, Arrows and Benetton and won

3600-454: The lock-ring type. In 1982, models featured a five-speed manual transmission option on gasoline-powered two-door cars (standard with diesel). The Scooter was newly available as a four-door hatchback. New GM THM-180C (THM200C for diesel model) automatic transmissions, which included a locking torque converter for greater fuel mileage, were available. Introduction of a pump-driven AIR system in the late model year replaced PAIR to help efficiency of

3744-420: The other direction, which leads to a secondary dynamic imbalance that causes an up-and-down vibration at twice crankshaft speed. This imbalance is common among all piston engines, but the effect is particularly strong on four-stroke inline-four because of the two pistons always moving together. The strength of this imbalance is determined by the reciprocating mass, the ratio of connecting rod length to stroke, and

3816-704: The past, for example the 1927–1931 Bentley 4½ Litre . Diesel engines have been produced in larger displacements, such as a 3.2 L turbocharged Mitsubishi engine (used the Pajero/Shogun/Montero SUV) and a 3.0 L Toyota engine. European and Asian trucks with a gross vehicle weight rating between 7.5 and 18 tonnes typically use inline four-cylinder diesel engines with displacements around 5 litres. Larger displacements are found in locomotive, marine and stationary engines. Displacement can also be very small, as found in kei cars sold in Japan. Several of these engines had four cylinders at

3888-405: The peak piston velocity. Therefore, small displacement engines with light pistons show little effect, and racing engines use long connecting rods. However, the effect grows quadratically with engine speed (rpm). Four-stroke engines with five or more cylinders are able to have at least one cylinder performing its power stroke at any given point in time. However, four-cylinder engines have gaps in

3960-399: The power delivery, since each cylinder completes its power stroke before the next piston starts a new power stroke. This pulsating delivery of power results in more vibrations than engines with more than four cylinders. A balance shaft system is sometimes used to reduce the vibrations created by a straight-four engine, most often in engines with larger displacements. The balance shaft system

4032-414: The previous wheel and hubcap design was discontinued. Domestic models received a new computer command control feedback system on gasoline engines. The HO option was discontinued. Electronic spark timing was used on 1981 models in place of mechanical timing advance. A new engine cylinder head design (swirl-port) was introduced to improve low-end torque and fuel economy . The Pontiac T1000 was introduced in

4104-493: The price of oil stabilized. The Chevette ultimately reached 2,793,353 sales for its entire production across the 12 model years 1976–1987. Global T-car sales surpassed 7 million in the end. The last Chevette was manufactured on December 23, 1986, at Lakewood Assembly – following the end of production at Wilmington Assembly in September, 1985. The last Chevette manufactured was a light-blue two-door hatchback shipped to

4176-559: The rear wheels. A four-speed manual transmission was standard, while a three-speed automatic transmission was optional. Other features included rack-and-pinion steering, front disc brakes, front stabilizer bar, 13-inch tires, tricolor taillights, front bucket seats, an onboard diagnostic system, extensive acoustic insulation, a single steering column-mounted stalk (integrating controls for signal indicators, wipers, and windshield washers), and factory options including swing-out rear quarter windows, AM/FM radio, analog clock, delayed wipers, and

4248-515: The sides, but lost the reclining levers of previous years. Interior trim was also blacked out with new black door handles and black plastic window regulators. An integrated cassette deck was optional with the stereo package. A chrome strip on the dashboard was available only on CS and S models until the end of production. Deluxe door panels were discontinued and all models featured plastic door panels, but base and Scooter models still featured laminated cardboard cargo area panels. The "diagnostic connector"

4320-510: The spring of 1981 for both the U.S. and Canadian markets, which shared all body stampings with the Chevette, featuring a chrome center with black-trimmed grille and headlight buckets, as well as standard chrome window trim with black area fill. The T1000 also had additional fresh-air vents at the outer ends of the dashboard. This gave Canadian Pontiac dealers 2 versions of the T-car: the Acadian and

4464-484: The world championship in 1983. The 1986 version of the engine was said to produce about 1,300 hp (969 kW) in qualifying trim. Belgian arms manufacturer FN Herstal , which had been making motorcycles since 1901, began producing the first motorcycles with inline-fours in 1905. The FN Four had its engine mounted upright with the crankshaft longitudinal . Other manufacturers that used this layout included Pierce , Henderson , Ace , Cleveland , and Indian in

4536-407: Was a sporting version of the hatchback called the 1.6 SR (with a mere four more horsepower, achieved by a somewhat higher compression ratio). In 1983, the Chevette received a thorough facelift with rectangular headlights, with the turn signals located underneath the headlights, a flatter hood, and a single-piece grille. The dash was also new, as were ventilation windows in the front doors. Mechanically,

4608-467: Was added to replace the THM-200 series automatic. An "HO" (high output) version was available in addition to the standard 1.6-liter, featuring a modified head and a larger valves-cam profile. The HO package also included a dual-outlet exhaust manifold. Prices were dropped and more standard equipment was added for 1978. Air conditioning, radial tires, an AM/FM radio, and power brakes were optional. In 1979,

4680-533: Was also dropped to $ 4,995. Sales fell to just over 46,000 units, and production ended on December 23, 1986. In 1978, General Motors Advanced Engineering developed a concept car, the Electrovette, based on the Chevette, but using an electric motor powered by lead-acid batteries.

4752-661: Was first launched by General Motors (Brazil) in 1973 as a two-door sedan. A four-door sedan followed in April 1978, and then a three-door hatchback was added in November 1979. The hatchback had unique bodywork for Latin America, longer than the European Kadett City and with a notch at the base à la the period Ford Escort .

4824-437: Was invented in 1911 and consists of two shafts carrying identical eccentric weights that rotate in opposite directions at twice the crankshaft's speed. This system was patented by Mitsubishi Motors in the 1970s and has since been used under licence by several other companies. Not all large displacement straight-four engines have used balance shafts, however. Examples of relatively large engines without balance shafts include

4896-453: Was led with great vigor by Fritz Lohr, who faced a lot of resistance at Opel and in the USA, as it required high investment, but without which Opel would have succumbed in the 70s/80s. The most curious thing about this story is that Lohr's specialty was chassis. But the three Brazilians, Francisco Satkunas, Pedro Manuchakian and I, actively participated in this project, with Pedro also taking care of

4968-570: Was originally designed as a 2 L Formula 2 engine for the Ferrari 500, but evolved to 2.5 L to compete in Formula One in the Ferrari 625. For sports car racing, capacity was increased up to 3.4 L for the Ferrari 860 Monza. The Coventry Climax straight-four engine was also a very successful racing engine, which began life as a 1.5 litre Formula 2 engine. Enlarged to 2.0 litres for Formula One in 1958, it evolved into

5040-491: Was removed from the wiring harness. In 1984, the low-cost Scooter model was discontinued, but kept for Chevettes made for Canada. The T1000 was renamed Pontiac 1000 in 1983 both in the U.S. and Canada. The 1985 models carried few updates from the 1984 models.

5184-646: Was the Chevy 500 pickup. After 1983, all Chevettes in Chile were imported from Brazil. When catalytic converters were made a requirement in that country, GMB was unable to develop such an engine and the Chevette was withdrawn from the Chilean market after the 1992 model year. Around 1.6 million units were built in Brazil, with the Corsa replacing the Junior and the Chevrolet Kadett/Ipanema replacing
