    The first domestically produced car in May 1967 (Showa 5)Rotary engineReleased as an on-board vehicle.1972From (Showa 47)1975Until (50), it was out of print for a while, but it was revived in the same year.1990In (2), it was developed from the previous year.EunosBrand flagship model,Eunos CosmoAppeared as1996It was released until (8).

    All modelscoupeI had a type of body (3 doors only for the 4rd generation)sedanAlso set), its properties differed greatly from generation to generation.In addition, except for the 3rd generation, it was released with different subnames for each generation.

    The first Cosmo Sports (1967-1972)

    Cosmo Sports1967(Showa42 years)52 seatercoupeIt was released as a model.At the same time, the world's first practical and mass productionRotary engineIt was also a car equipped with.

    The world's first commercially available rotary engine-equipped vehicle is, to be exact, old.NSU Wankel 1964Released in (39)Rear enginecar'sWankel SpiderIs.The engine installed in this engine had many problems peculiar to rotary engines remaining unsolved, so to speak, it was a "close-out release".It was also a single rotor engine.On the other hand, it was installed in Cosmo Sports.10A type engineWas able to overcome these problems and withstand mass production.For this reason, the 10A engine is the world's first practical and mass-produced rotary engine.The 10A engine was also the world's first multi-cylinder (multi-rotor) rotary engine for commercial vehicles.

    The characteristics of rotary engines have been proven in various rotary piston engine theories.However, despite more than 100 years of theoretical accumulation, rotary engines have not yet been mass-produced.For this reason, the Cosmo Sport, which is equipped with a 10A engine, can be said to be a memorable existence that first installed a rotary engine as an engine for mass-produced vehicles.

    1968(Showa 43) In August, holding Cosmo Sports under the name of mazda8SNürburgring84 hours done inEndurance raceI challenged "Marathon de la Route".This race is a literal marathon race in which the speed and durability of production vehicles are competed.Porsche,Lancia,BMW,SAAB,Opel,Simca,DatsunAnd developed a fierce battle.As a result, not only did he finish the race, but he was also 4th overall after Porsche Lancia (ranking is determined by the mileage after 84 hours).Winning a prizeIt became.Of the 59 cars that participated, only 26 completed the race.

    Installed in Cosmo Sports10A type engineAfter thatFamilia rotary coupe,Savanna RX-3It was installed in such as. The 10A engine consists of five housings (two cylinders and three plates), and since the development purpose is for mounting on sports cars with a small mass production scale, the engine can be up to two rotor housings of 5 2 3c. All includingAluminum alloyMet.In mass-produced models after Cosmo Sports, the side housings (front, intermediate, and rear) arecast ironHas been changed to.Cosmo Sports 10A engine is made of carbon steelThermal sprayingWhile it is expensive and elaborate, the engine after the 10A engine uses special cast iron at high frequency.QuenchingProcessed products are used for mass production and cost reduction.Also, the processing method is Cosmo Sports sand mold.castingAgainstMoldIt was cast and mass-produced.

    Cosmo Sports is the early model (L10A type)1967Starting with the sale of 42 units in (Showa 343),1972A total of 47 units have been sold up to the final sales of the late model (L10B model) (1,176).

    1963(38)10/26から11/1010th held inAll Japan Motor Show(Later Tokyo Motor Show),Mazda rotary engineThere are two types, 400cc x 1 rotor (35PS) and 400cc x 2 rotor (70PS).Trial productionThe engine was exhibited, and a photo panel of the "Rotary engine test prototype (Cosmo Sport prototype)" was also posted at the venue.[1]..There was no vehicle on display[Annotation 1]At that time, President Tsuneji Matsuda himself took the steering wheel of Cosmo Sports' primary prototype car "MAZDA 802 (L402A)" and got on the car show venue all the way from Hiroshima to get a lot of attention.Also, on the way back, each sales company,Main bank OfSumitomo Bank,Hayato IkedaThere is also an episode of visiting the prime minister and others.The first Cosmo Sports prototype was released to the public on the Asahi Shimbun on October 6, 1963, six days before the car show was held.[3]In, this was the Asahi Shimbun scoop.

    By the way, there are at least two types of primary prototype cars, and the individual with the "Hiro 5 So 32-85" license plate (registered in August 1963) has no plating molding on the weather strips of the front and rear window screens, and the wiper. Is a parallel 8-blade, the emblem mounting position of the quarter pillar is lower, the mounting position of the car radio antenna is between the rear glass and the trunk lid, and the horizontally long tail lamp is a four-lamp type with a partition in the center. Ta[4][5][6][7].. The individual with the "Wide 5 So 57-35" license plate (registered in October 1963) has a plated molding on the weather strips of the front and rear window screens, and the wiper is a parallel 10-blade emblem of the quarter pillar. The mounting position was in the center of the pillar, the mounting position of the car radio antenna was on the upper part of the right rear fender, and the horizontally long tail lamp had no partition in the center and looked like a two-lamp type on the outside (of the lamp installed inside). The number seems to have been based on 2-32 cars)[8][9][10].

    These two "MAZDA 802" appeared as a surprise in the parking lot of the car show.[11]..Five primary prototype cars have been manufactured by the time the car show is held.[11].

    Next day1964(Showa 39)9/26から10/9For the first time at the 11th Tokyo Motor Show held in Tokyoprototype) Was officially exhibited.The name at the time of exhibition was "MAZDA" COSMO"Met.The engine installed is the L399A type (2ps / 8rpm) with a 70cc x 6,000 rotor.The car exhibited at the show was a secondary prototype car, and the design of the tail part was significantly different from the primary prototype car, and it was close to a mass-produced car.In addition, a triangular window has been added to the side window, the wiper is a two-blade facing type, and the louver of the front fender, which is one of the features of the appearance, is a plating of thin slits from the 2-hole plating of the primary prototype car Was changed to[12]..Up to the second prototype car, cover the left and right quarter pillars at the rear of the roofWhite coverWas installed[13]This was also a major feature of the appearance.Multiple secondary prototypes have been manufactured, with a parallel 2-blade wiper, a half-cover type wheel cover with a 5-hole wheel, a center-lock wire-spoke wheel, and a quarter pillar. The width of the wheel is narrow, the vent of the cowl top is grid-like like the primary prototype car, the air outlet on the front fender side is not louver-shaped, the outer handle of the door is long and there is no dent on the door panel, the front turn There were various specifications such as signal lamp lenses with amber color.[14][15][16].

    1965(40)10/29から11/1A prototype of Cosmo Sports was exhibited at the 12th Tokyo Motor Show held in Tokyo.The name of the exhibited vehicle is "MAZDA" this year as well. COSMO"Met.The pamphlet distributed at the show venue stated that "the revolutionary engine (...) has 2 rotors and a single room volume of 500cc", so the exhibit vehicle has a 491cc x 2 10A engine (prototype). It is probable that was installed.In the exhibited car, which seems to be the third prototype car, the white roof cover was omitted and the entire roof and quarter pillars were painted white, and the design of the full cover type wheel cover was slightly changed.In addition, the louver of the front fender was a simple one in which a slit was press-molded directly on the fender panel.This is a design change to reduce the number of parts and man-hours on the manufacturing line and reduce costs.The exhibition car at this timeFinal production typeWas announced, and Mazda all over the countrydealerIt was announced that it would be commissioned to conduct a practical test (at that time, details would not be disclosed).[17].. The prototype vehicle named "Outsourced Test Vehicle" is the third prototype vehicle "MAZDA" due to the characteristics of each part of the car body. COSMOOr it is presumed that it was an improved version of the third prototype car.Initially outsourced testing1965(40) Started in August, the number of test vehicles to be rented was planned to be 8.[18].

    1966(41)10/26から11/8The Cosmo Sports prototype was exhibited at the 13th All Japan Auto Show held in Tokyo.The name of the exhibited vehicle is "MAZDA COSMO" SPORTS(The name of the commercial model is "MAZDA COSMO" SPORTS").Further improvements were made based on the practical test,1967(Showa 42) Scheduled to be released in the spring, announced that the price is undecided[19].

    By the time it was put on the market, outsourced tests were lent to dealers around the world. COSMO47 units[20]By1966(Showa 41) It was carried out over a period of one year from January to December, and during that time, the head office conducted a running test with a total distance of 1 million km, including a continuous durability test of 12 km with a prototype vehicle. It was conducted.

    Early type

    The early model L10A of Cosmo Sports was equipped with a 10A rotary engine (491 cc x 2). High of 9.4Compression ratioAnd twinplugBy 110 PS final match. rpm, 13.3 kgf· M / 3,500 rpm was demonstrated.Vehicle weight is 940kgIt was relatively lightweight.

    The basic layout other than the engine was common sense in this eraFront engine/Rear driveHowever, it had quite advanced specifications for a Japanese-made passenger car at that time.suspensionThe front isDouble wishbone+ Coil springIndependent suspension, The rear suspension was abandoned, but the unsprung weight was reduced.De Dion AxleWas hung with a leaf spring.SteeringQuick on gearRack and pinionThe format is adopted.ト ラ ン ス ミ ッ シ ョ ンIs 4-speed fullSynchroAnd the front wheels of the brakes are Dunlop typedisk, Rear wheels are AlfinDrumMet.The front and rear brakes are tandem master cylinder type with independent systems, which is highly safe in case one of them breaks down.

    The rotary engine is as low as possible and is placed at the rear, later Mazda'sidentityThe front deskMidshipThe idea of ​​was already utilized.It is a heavy objectbatteryIs in the early modeltrunkIn the latter model, it was housed in a case with a lid that opens and closes with a knob provided at the rear of the passenger seat.

    The body specially designed for mounting a rotary engine is semiMonocoqueIt was a method.The body had no seams other than the opening, and it looked like a handmade special car.Also, the lids of the opening are all safe in anticipation of the coming high speed era.Hinge(The engine hood is a reverse alligator).In designing, a bold and innovative style suitable for an innovative rotary engine was desired.At the beginning of development, he was the president at that timeTsuneji MatsudaIt is said that this drastic styling was born because it was said that it was an image car that I did not intend to sell.

    The total height was as low as 1,165 mm.

    Driving performance

    The running of the rotary engine isReciprocating engineBrought a different dimension of sensation.At that time, most domestic cars equipped with reciprocating engines started at around 4,000 rpm.noiseとvibrationBecomes larger, 100 km / h At high speeds exceeding the above, even conversation became difficult, and it was sometimes necessary to yell at each other.But the rotary engineRed zoneIt blew quietly and smoothly up to 7,000 rpm.

    Although it cannot be concluded unconditionally due to differences in road conditions and test conditions of each age group, it is the top value in fuel efficiency among the above cars.

    Late type

    Due to minor changes, it was a luxury item at that timeDiesel equipmentMade ofCar coolerCan be installed as an option.The price of this diesel device cooler is said to have exceeded 40 yen.The unit was placed in the baggage space behind the seat, so the cold air was blown from behind.The effect was not bad because it was a cooler designed exclusively for Cosmo Sports, but since the rotary, which is less prone to snatching, was able to run at low speed with TOP gear, the instruction manual at that time stated that "cars equipped with a cooler shift when the cooler operates. TOP andO ・ TIf you are driving at a low engine speed of 1,500 rpm or less, you may feel overheated. In such a case, set the shift to 2nd or 3rd speed. "(Original) to call attention.

    2nd generation Cosmo AP / Cosmo L (1975-1981)

    Cosmo AP

    It was revived as Cosmo AP in October 3, three years after the discontinuation of Cosmo Sports production.

    What is AP? Anti-pollutionPollutionIt is the meaning of measures.Oil shockThis is the first model announced by Mazda later, and has a different route from Cosmo Sports.Specialty CarIn the background that becameNorth AmericaThere was a market demand.For this reason, the interior and equipment have been extruded with a sense of luxury and luxury, and have attracted attention along with the red body color. The CM character is Keiko Usami.Shibata Hatsumiof"My Luxury NightWas appointed as a CM song, and the song was a big hit.

    2 generationLuce OfMonocoqueBy sharing the floor panel of MazdaFlagship modelThe suspension, interior, and equipment have been newly designed.The newly designed parts were designed to reduce costs by sharing parts in consideration of diversion to other Mazda vehicles (such as Luce and Capella).

    The early model has 4 round lightshead lampAnd L-shapedtail lamp, Vertical toneradiatorgrillAnd Mazda's originalAerodynamicstheory[Annotation 3]based onEngine hoodIt was characterized by the treatment of the tip.1979In the minor change of, the atmosphere was completely changed by changing to two irregular square headlamps, a grid-like grille, and a horizontally long tail lamp.

    The engine is 135PS13B type engine, 125PS12A type engine,Reciprocating engineThere were four types of variations, 2,000cc (MA type) and 1,800cc (VC type).Of these, the reciprocating 4㏄ engine (MA type) iscarburetorbyThree-way catalystIt became the first engine in the industry and was added when the Cosmo L was announced. The 1800㏄ VC type isThermal reactorSince we were taking measures against the pollution of the ceremony, it was gradually changed to the MA type.

    As for the suspension, the lower arm is the A arm at the front.Strut type, Rear is 5Link typeIt was adopted.

    At that timeCar emission regulationsDue to the influence of, sports models are disappearing one after another, and the powerful Cosmo AP that appeared in it became a prominent presence, and it became a big hit with sales of 2 units in half a year from its release.

    The export name was "Mazda RX-5" for vehicles equipped with a rotary engine and "Mazda 121" for vehicles equipped with a reciprocating engine.

    Cosmo L

    Cosmo AP2 years late from19777Was added as a variation model to. "L" is an acronym for Landau Top, which is high-classCarriageIsLandolletIt is a name derived from the roof type of.The biggest feature is, as the name suggests, Landau Top.At Cosmo APFastbackIt was, but in Cosmo LNotch back + Opera window (English edition) + Half leather top (vehicle Ofroof).This is also due to strong demand from the North American market.MustangIncludingToyota OfCorollaandCelicaThere are also two types of back-style coupe bodies.

    Landau Top's Cosmo L has plenty of room above the rear seats, is comfortable to live in, and has a small quarter window (called the opera window).PoliciesEven if there is no difference in performance and equipment from the Cosmo AP, it was positioned as a high-end model for a slightly older age group.

    1979 Minor change. As with the AP, the front mask was changed to two irregular square headlamps and a grid-like grille.

    Apart from the evaluation in the market工場The evaluation within was completely different.For fastback vehicles, use the pressed body panelWeldingWhen doing so, the welded part of the C-pillar will be exposed, so it is usuallysolderThere was a process of filling the surface with and finishing it gently.At Landau Top, this process could be omitted.leadNo pollution occurred, and in that sense it was highly evaluated.

    3rd generation Cosmo (1981-1990)

    1981The 3rd generation Cosmo that appeared in the 4th generationLuceとSister carBecame.There are three types of body variations, but the time of appearance of each is complicated, so first of all9/1[23]Two-door hardtop was released in advance, one month later10/1[24]4-door hardtop, 2 weeks later10/16[25]A 4-door saloon (sedan) and a car equipped with a rotary engine were announced at different times.It features an aerodynamic design, and the hardtop has four lights.Retractable headlightshave.Among them, the Cd value of the two doors was 2, which was the world's top class at that time.Initially, only the MA type 0.32-cylinder 4cc reciprocating engine (EGI and carburetor specifications), which is the same as the conventional type, was released in advance, but the 2,000cc diesel engine (saloon only),12A typeA rotary engine (573cc x 2) was also added at the same time as the 10-door saloon on October 16th.

    12A型ロータリーエンジンは新たに6PI(シックス ピー アイ)と名付けられた、6ポート・インダクションを採用、これは従来1ローターあたりプライマリーポート、セカンダリーポートと吸気ポートを2つ(2段階)設けていたものを、新たにセカンダリーポートをメインポートと排圧で開閉する補助ポートとに分割し、1ローター毎3ポート(3段階)、2ローターで計6ポートとしていた。これにより回転数や負荷に見合った吸気タイミングの最適化を図り、燃費や出力の向上を謳っていた。

    19829[26],12A typeLaunched rotary turbo car (world's first with Luce). Named the "whole-speed turbo," this engine boasted top-class performance among domestic cars in 1982 and pioneered the high-performance war that took place in the 1980s.

    In the interiorデ ジ タ ルWhile transmitting information by changing the areaSpeedometer, Arranged at both ends of the meter nacelle where the influence of the satellite switch can be seenAir condition, Lights,WiperSuch as switches,cassette tape(Compact cassette) Is adopted as an upright transport with a design that showsCar Audio(Mitsubishi Electric(Co-developed with), and features such as a seat back folding mechanism.

    Of a car journalistKazuhiko MitsumotoIn September 1982, Cosmo Rotary Turbo with three car journalistsIbarakiTsukubaYatabe Town(CurrentTsukuba City)ofJapan Automobile Research InstituteIn, Yatabe 24-hour endurance test was conducted.As a high-speed endurance trial2000GTAlthough it is famous, it exceeds the new international record of 6km / h of 2000GT at 210.42 hours (finally 2000GT averages 72km / h in 206.02 hours).

    1983Minor change in October.Due to its unique design, sales were not good with Luce, so the front mask of the 10-door hardtop was changed to a general fixed headlight.At the same time to a 4-door system13B typeSet up a rotary super injection car.The 2-door hardtop inherits the conventional retractable headlights.

    1984In September, a minor change was made to the 9-door hardtop. Improvements other than "GT" will be made, and it will be replaced with fixed headlights similar to 2-door.

    1985In May, the "Gentile" series was introduced to reciprocating engine cars as a way to sort out grades and add stakes at the end of the model.

    1986In September, with the remodeling of Luce, Cosmo abolished the 9-door saloon and rearranged it to only the 4 / 2-door hardtop. It will continue to be produced until the appearance of Eunos Cosmo in April 4.

    1988October, partial body color replacement

    1990In April, with the advent of Eunos Cosmo, the production of the third generation was discontinued.

    4th generation Eunos Cosmo (1990-1996)

    1990January,EunoscosmoIs the first mass-produced car with 3 rotorsRotary engineEquipped withAutomobileAppeared as.The catch phrase is "Coupe dynamism』.The body is a 2-door coupe only.

    At that time, Mazda was planning to expand its sales channels (Mazda, Eunos,Éfini,Autozam,Autorama), This car is of the Eunos brandFlagshipMet.Among the successive Cosmo, it is a rotary engine dedicated car since the first Cosmo Sports, and the engine13B-REW typeAnd, two types of 3B-REW type with 20 rotors, which is the world's first commercial vehicle, were set.The Eunos emblem used in this car is modeled after a rotor like the Cosmo Sport.

    Called the world's first "CCS" that attracted attentionGPSCar navigation(Mitsubishi Electric(Co-developed with) is standard equipment on the TYPE-E. CCS grade of vehicles equipped with 20B.In addition, like a luxury coupe, there was a certain amount of attention to the interior, and the wood panel customized in Italy was attached to the instrument panel, but it was not attached to the entire surface, and it was arranged effectively and organized well.Furthermore, the operation of the fully automatic air conditioner doubles as a car navigation display.Touch panelIt was an epoch-making method at that time that it could be operated only by the car, and since then it has become popular mainly in luxury cars at each company.If the car navigation system is not standard equipment, a fully automatic air conditioner operation panel with LCD will be attached.BothSequential twin turboThis was the first Japanese car to be adopted.Grades are TYPE-ECCS, TYPE-E, TYPE-S (early / mid-term type), TYPE-SX (late type only).platform TheMazda / JC PlatformHas been adopted.

    The dream of a Mazda engineer, "Has the smoothness of a V12 engineThe 3B engine, which is a three-rotor engine that is said to have a very high output, was originally designed with 20 horsepower, but at that timeMinistry of Transport(Later, the RX-7 2-rotor 13B-REW also achieves 280 horsepower)Within the domestic self-regulation frame of 280 horsepowerIt was necessary to put it in the box, and it was detuned and put on the market.The exhaust port has been changed compared to the 13B to lower the exhaust pressure to the turbo and suppress the maximum output.

    Due to its output and structure, depending on the media, "Super fuel-efficient car with a liter of 3 kgMay be introduced[28], The actual fuel consumption in city driving is best to maintain 2km / L, and it is said that the fuel consumption is the worst in the world depending on the conditions.Bugatti VeyronSometimes it deteriorated to the average 1km / L level[29].. The 20B rotor and rotor housing are the same size as the 13B,DisplacementAlso, 3-rotor vehicles fall into the category of 3,500 cc or less.Its high fuel efficiency isBubble economyEven in those days, it was a sufficient factor to hesitate to buy.

    The sequential twin turbo is different from the one installed in the RX-7 (FD3S type), and different size turbines are adopted on the primary side and the secondary side. The muffler of the 20B-REW equipped car has a variable exhaust function that changes the route in the high rotation range, and the number of opening ports changed due to the rotation of the four mufflers.In terms of appearance, the 4B-REW-equipped vehicle has two tail pipes, while the 13B-REW-equipped vehicle has four tail pipes, making it easy to distinguish.
