60-677: The predecessor of the Porter, introduced in February 1961, the Mazda B360, was available as a pickup (KBBA33) or light van (KBBAV) version of the R360 kei passenger car. It had a 356 cc OHV V-twin producing 13 PS (10 kW) ( BA ) and weighed 535 kg (1,179 lb). The 1961 export only Mazda B600 (KBEA) was similar to the B360 except that it received an enlarged 577 cc version of

120-445: A displacement of just 150 cc (or just 100 cc for two-stroke engines ) in 1949, dimensions and engine size limitations were gradually expanded in 1950, 1951, and 1955, to make kei cars more attractive to buyers, and production more viable to manufacturers. In 1955, the displacement limit was increased to 360 cc for both two-stroke and four-stroke engines , resulting in several new kei car models beginning production in

180-459: A 4-speed manual transmission, whereas the second generation KRBC came with a 2-speed "TORQ DRIVE" automatic transmission. The standard Mazda R360 came in 3 different exterior whole-body colours; Opal Green, Maroon Rouge and Somerset Blue. The non-standard Deluxe Mazda R360 came in multi colour variants; Blue and Cream and Red and Cream. For the interior of the Mazda R360,

240-458: A continued market existed for the kei car. As sales improved, these engines only lasted for a model year or so until manufacturers had the time to develop maximum-sized engines. Only Daihatsu had a 550 cc engine ready and thus avoided developing transitional engines that did not immediately take full advantage of the new regulations. Kei car sales remained stagnant, however; while combined passenger and commercial kei car sales reached 700,000 for

300-537: A darker grey, interior brown. In 1985 there was another minor facelift, with trim pieces now in black and a black band between the headlights. The engine switched from a timing chain to a timing belt, and the interior changed to gray. Air conditioning was now available as an option. In 1987 the Mitsubishi Minicab received Mitsubishi's new three-cylinder engine, but the Porter Cab had to soldier on with

360-450: A displacement increase of 110 cc (6.7 cu in), or twenty percent, while the maximum length was increased by 100 mm (3.9 in). These changes occurred during the 1990s Japanese economic bubble , and all manufacturers quickly developed new models to suit. Within five months, all major kei models had switched from 550 cc to 660 cc engines. For the first time, a power limit of 64 PS (47 kW; 63 hp)

420-569: A few years of introducing the R360, Mazda had captured much of the lightweight (kei car) market in Japan. The R360 was augmented by the Mazda P360 "Carol" two-door and four-door sedan in 1962. Production of the R360 lasted for six years. There were two variants of the Mazda R360, officially known as KRBB and KRBC. Both variants were very similar visually, however the first generation, KRBB came with

480-493: A governmental backlash. This power limit matched the highest output reached by any kei manufacturer at the time and was a gentlemen's agreement amongst the manufacturers in an effort to avoid a kei-class horsepower war. The only kei car to have exceeded this limit is the Caterham 7 160, a lightweight British sports car that was not expected to qualify as a kei car, though it is small enough (in dimensions and displacement) to fit

540-566: A kei car in Japan, a kei version of the Smart Fortwo (called the Smart K ) was sold in Japan by Yanase from 2001 to 2004. The Smart K used revised rear fenders and reduced tire dimensions and track width to conform to kei regulations. The model was not a success, and sold the fewest examples of a kei car when it was marketed. The Suzuki Wagon R was the best-selling kei car in Japan between calendar years 1996 and 2011, except in 2003, when

600-618: A lower overall ownership cost. In most rural areas they are also exempt from the general Japanese shako shōmeisho ( 車庫証明書 ) parking-space ownership requirement to legally buy a motor vehicle at all, as street parking is generally restricted in Japan. Japan's carmakers also make microvans and kei trucks within this legal category. The kei category was created by the Japanese government in 1949, to stimulate both car ownership and growth of Japan's car industry. The regulations were revised multiple times until 1998, but since October 1998,

660-457: A quarter of its overall sales. In April 2014, the Japanese government significantly reduced advantages for kei car owners, imposing a higher sales tax, a higher gasoline tax, and a higher kei car tax, the last of which was raised by 50 percent—greatly reducing tax benefits compared to regular-sized cars. Daihatsu, Honda, Suzuki and Nissan-Mitsubishi (through the NMKV joint venture) are currently

720-428: A quarter of the exported kei vehicles. Due to the difficult economic environment, low-priced cars sold well at the turn of the decade; 1981 marked another successful year as Japanese kei car sales reached their highest since 1970 (at 1,229,809 units for cars and trucks). This was also thanks to a new phenomenon: To help boost their sales, Suzuki developed a new car which could be sold as a commercial vehicle although it

780-401: A regular car. A 24-month insurance contract typically costs ¥18,980 at the time of registration versus ¥22,470 for a larger car. An automobile weight tax also is levied: The amount is ¥13,200 and ¥8,800 for a three- and two-year period, respectively, as compared to the ¥18,900 and ¥12,600 charged for larger-sized passenger cars. The savings are thus more than 30% in both cases. This weight tax

840-545: A single electric motor with a maximum output of 47 kW (63 hp; 64 PS). The eK X EV is a battery-electric version of the Mitsubishi eK X, and the Sakura is an update to Nissan's Dayz line. The two are eligible for EV purchase incentives in Japan, and as of June 2022, are also the cheapest new BEVs from a major Japanese manufacturer. The vehicle excise tax levy is 2% of the purchase price, compared to 3% for

900-730: A version of the German-made Smart Fortwo was briefly imported and officially classified as a kei car. In addition, the British Caterham 7 160 and the Polish Polski Fiat 126p (Maluch) also received such classification. Japanese government regulations limit the outer physical size, and ( combustion ) engine displacement and power output of kei cars, see detailed table below. Kei cars have also been subject to other restrictions, chiefly lower speed limits than bigger vehicles; older Kei-cars also had

960-544: A warning chime that sounded when being driven too fast. Kei cars are issued special license plates , with black numbers on a yellow background for private use, and yellow numbers on a black background for commercial use, earning them the name "yellow-plate cars" in English-speaking circles. Modern Kei cars are often available with turbocharged engines, automatic and continuously variable transmissions, and choice of front-wheel or all-wheel drive . After

1020-521: The Chantez ' 35 PS (26 kW) 359 cc water-cooled, two-stroke two-cylinder in April 1973, which brought with it some cosmetic changes (KBAA/KBAAV). In 1975 the Porter was modified to fit new, larger license plates and the engine downgraded to 32 PS (24 kW) to match new, stricter emissions regulations. The wheelbase was 1,995 mm (78.5 in) with leaf springs in the rear, weight

1080-789: The Daihatsu Move outsold the Wagon R. Starting in 2011, Toyota entered the kei car market for the first time. The resulting Toyota Pixis Space, a rebadged Daihatsu Move Conte , was expected to increase competition in that market. Nissan and Mitsubishi began to jointly produce the Mitsubishi eK (also sold as the Nissan Dayz and formerly the Nissan Otti). Honda's kei car lineup—the N-one , N-Box , and N-WGN —accounts for around

1140-612: The Honda Z GS of January 1970. Power outputs also kept climbing, reaching a peak with the 40 PS (29 kW; 39 hp) Daihatsu Fellow Max SS of July 1970. Sales increased steadily, reaching a peak of 750,000 in 1970. Until 31 December 1974, kei cars used smaller license plates than regular cars, at 230 mm × 125 mm (9.1 in × 4.9 in). From 1975, they received medium-sized standard plates, which are 330 mm × 165 mm (13.0 in × 6.5 in). To set them apart from regular passenger cars,

1200-471: The 'A' market-segment of motor vehicles. Although some Kei models are successfully exported or licensed, the great majority are designed and built for the Japanese domestic market only, as they are entirely optimized to offer the most appealing vehicles within the very specific to Japan Kei-car rules, in addition to mainly being built with the steering on the right. Contrary to popular belief, according to

1260-552: The 1 January 1990 regulations, there is no official power limit for Kei cars. The limit is dictated by a Gentleman's Agreement between Japanese auto manufacturers as the most powerful Kei car at the time was rated at 64 PS (47 kW; 63 hp). This agreement was reached to prevent a horsepower race, and to remain true to the modest spirit of the Kei class, to charge lower tax on small vehicles that are just enough to meet basic transportation needs. The kei legal class originated in

1320-516: The 1960s, consisting of over one-third of domestic new-car sales in fiscal year 2016, after dropping from a record 40 percent market share in 2013. To lower the market share of kei cars, Japan increased taxes on the category by 50% in 2014. In 2018, seven of the 10 top-selling models were nonetheless kei cars, including the top four, all boxy passenger vans : the Honda N-Box , Suzuki Spacia , Nissan Dayz , and Daihatsu Tanto . For exports,

1380-445: The 1980s progressed, kei cars became increasingly refined, losing their utilitarian origins, as Japanese customers became ever better off. Features such as electric windows , turbochargers, four-wheel drive , and air conditioning became available on kei-car models. Conversely, van versions of kei hatchbacks were now marketed to non-business customers to take advantage of even lower taxation and more lenient emissions rules; this move in

1440-668: The 1980s, Kei cars had matured so much in power, speed, and passive (crash) safety, that they were no longer bound to lower maximum speeds than other cars. Japan's carmakers since agreed on a self-imposed maximum 140 km/h (87 mph) speed, mostly because of their narrow width. Kei cars are often considered the Japanese equivalent of the European Union 's A-segment "city cars". However, contrary to Japan's special Kei cars' legal status and limitations, there are no EU- or pan-European legal restrictions, exceptions or benefits for what European auto journalism or market analysts call

1500-674: The B360 was replaced by the Mazda E360 in 1967. A larger B600 pickup was introduced for the export market. It used a 577 cc version of the Mazda V-twin. Kei car Kei car is the smallest category of Japanese expressway -legal motor vehicles. The term kei is a shortening of kei-jidōsha , ( kanji : 軽自動車 ), which translates to English as "light automobile" ( pronounced [keːdʑidoːɕa] ). With restricted dimensions and engine specifications, owners enjoy lower tax and insurance rates which lead to

1560-483: The Chantez. In January 1975, the Porter Cab too was lightly modified to fit the new larger license plates - hitherto, kei cars had carried smaller license plates than regular cars (230 mm (9.1 in) x 125 mm (4.9 in) rather than 330 x 165 mm). In April 1976 the Porter Cab also received an engine which met the new, tougher 1975 emissions regulations and the model code PC3A . The only color available

1620-726: The Japanese Transport Ministry. It was the world's first mass-produced electric car, and the first electric car to sell more than 10,000 units. Rebadged and slightly updated variants of the i-MiEV were also sold in Europe as the Peugeot iOn and Citroën C-Zero . In 2011, Mitsubishi launched the MINICAB-MiEV; a battery electric version of the Minicab microvan, borrowing the drivetrain and key components from

1680-572: The Mazda Pathfinder and the Hino TE truck . The truck was kept in production until the mid-1990s with 100 percent local content. Always painted in blue from the factory, these were ubiquitous as taxis in Burma ( Mandalay in particular) until after the markets opened up in 2011. Available either as a pickup truck (KBDB33) or a small van (KBDBV), the first Porter ( E360 in export markets)

1740-559: The New Porter Cab which appeared in 1977 (PC4D). The Porter Cab was stretched by 200 mm (almost entirely behind the rear axle, with the 1,835 mm (72.2 in) wheelbase remaining unchanged) and widened by 100 mm (3.9 in). Dimensions were now 3,195 mm (125.8 in) x 1,395 mm (54.9 in) as per the updated standards, and the 546 cc Vulcan S two-cylinder developed 29 PS (21 kW) at 5500 rpm. The headlight bezels were squared off, lending

1800-443: The R360 featured a 1,760 mm (69.3 in) wheelbase, weighed 380 kg (838 lb) and was powered by a rear-mounted air-cooled 356 cc V-twin engine producing 16 PS (12 kW) and 22 N⋅m (16 lb⋅ft) of torque. The car was capable of 84 km/h (52 mph) and featured a 4-speed manual or two-speed automatic transmission. The suspension, front and rear, was rubber "springs" and torsion bars. Within

1860-508: The air-cooled V-twin. This engine produced 20 PS (15 kW) and 3.8 kg⋅m (37 N⋅m; 27 lb⋅ft) of torque. In September 1963 the B360 gained the four-cylinder, 358 cc 20 PS (15 kW) DB OHV engine from the Carol. It also received a facelift, with a larger grille using the same look as the B1500 truck . The modelcodes changed to KBDA33/KBDAV, and a DeLuxe Van version

1920-425: The car a more conventional appearance. In 1979 the car gained two more horsepower. The second generation Porter Cab was only available in a bright blue color with light grey trim (bumpers, headlight bezels) and black interior, until the 1983 facelift after which only white was available. The facelifted version gained the cleaner Vulcan II engine ( G23B ), although power output remained the same. Trim pieces were now in

1980-455: The era following the end of World War II , when most Japanese citizens could not afford a full-sized car, though many had enough money to buy a light motorcycle . To stimulate growth of the car industry, as well as offer alternative commuting means, and small delivery vehicles for shops and businesses, the kei-car category, reduced tax-burden, and accompanying legal maximums for "essential transportation" vehicles were created. At first limited to

2040-657: The first time since 1974, the small cars still lost market share in a quickly growing market. As the kei cars became larger and more powerful, another benefit appeared as exports increased considerably. In particular, export sales of kei trucks increased, while kei passenger car exports increased at a lower rate. In 1976, the number of exported kei cars and trucks combined was 74,633 (up 171% year-on-year), despite exports of passenger kei cars decreasing. In 1980, another record year occurred as exports grew by 80.3% (to 94,301 units), of which 77.6% were microtrucks. Nearly 17% of exports went to Europe, dwarfed by Chile , which took nearly

2100-492: The following years. These included the 1955 Suzuki Suzulight and the 1958 Subaru 360 (considered the first truly mass-produced kei cars), which were finally able to fill people's need for basic transportation without being too severely compromised. In 1955, the Japanese Ministry of International Trade and Industry (MITI) also set forth goals to develop a " national car " that was larger than kei cars produced at

2160-654: The i-MiEV. As of March 2015, over 50,000 units across all variants (including the two minicab versions sold in Japan) have been sold worldwide since 2009. Production of the i-MiEV was discontinued in 2021. In May 2022, NMKV launched the Nissan-badged Sakura and the Mitsubishi-badged eK X EV in the Japanese domestic market . These models have a 20 kWh lithium-ion battery pack with an estimated WLTC range of 180 km (110 mi). Both use

2220-438: The law consistently specifies a maximum vehicle length, width and height under 3.4 m (11.2 ft), 1.48 m (4.9 ft) and 2.0 m (6.6 ft), respectively, and engine displacement under 660 cc (40.3 cu in). A " gentleman's agreement " for a maximum power of 64 PS (63 hp; 47 kW) was reached between Japanese automakers and lawmakers. Kei cars have been very successful in Japan since

2280-607: The market was spearheaded by Suzuki with their 1979 Alto , and competitors soon followed suit, with the Subaru Family Rex and the Daihatsu Mira appearing within a year's time. In the 1980s, the speed limit for kei cars was 80 km/h (50 mph). Government rules also mandated a warning chime to alert the driver if this speed was exceeded. The kei car regulations were revised in March 1990, allowing engines

2340-577: The mid-1960s, when the kei speed limit was increased to 60 km/h (37.3 mph). The early vehicles were comparable to the European 'bubble-cars' of the era. The class then went through a period of ever increasing sophistication, with an automatic transmission appearing in the Honda N360 in August 1968, and front disc brakes becoming available on a number of sporting kei cars, beginning with

2400-399: The new requirements. All manufacturers of kei cars were clamoring for increased engine displacement and vehicle size limits, claiming that the emissions standards could not be met with a functional 360-cc engine. In the end, the Japanese legislature relented, increasing the overall length and width restrictions by 200 mm (7.9 in) and 100 mm (3.9 in), respectively. Engine size

2460-549: The official colour choices were Red or Blue. These colour options were available for the seats, carpet and inner door panels. The B360 was a pickup truck bodystyle based on parts of the R360 Coupé. It used the same 356 cc engine, but in a front-engine, rear-wheel-drive layout . Like most pickups, it used a rigid rear axle and leaf spring suspension. The engine was replaced with the Carol 's 358 cc I4 in 1964, and

Mazda Porter - Misplaced Pages Continue

2520-476: The old two-cylinder. In June 1989, after twenty years of continuous production with nothing more than facelifts, the Porter Cab was finally retired. It was replaced by the Autozam Scrum , a badge-engineered Suzuki Carry . Mazda R360 The Mazda R360 is a kei car manufactured and marketed by Mazda as the company's first passenger car — a two-door, four-seat coupé . Introduced in 1960,

2580-424: The only mass-production manufacturers of kei cars. Mazda sells rebadged Suzuki models, Toyota and Subaru sell badge-engineered Daihatsu models, and Nissan-Mitsubishi sources their commercial kei models from Suzuki. The electric version of the Mitsubishi i , the Mitsubishi i-MiEV was the first electric kei car. This was launched for fleet purchasers in 2009 in the Japanese domestic market . It became available to

2640-439: The plates were now yellow and black rather than white and green. Throughout the 1970s, the government kept whittling away at the benefits offered to kei vehicles, which combined with ever stricter emissions standards to lower sales drastically through the first half of the decade. Previously exempt, mandatory annual inspections for kei cars were added in 1973 and put an additional damper on sales. Honda and Mazda withdrew from

2700-469: The production equipment to Burma; this was part of Japanese war reparations to Myanmar. After strict sanctions were imposed in 1988 and the import of Japanese parts became impossible, manufacture shifted to MADI (Myanmar Automobile and Diesel Engine Industries). The little trucks were built in the "No 2 Automobile Industry" plant in the small town of Tonbo, at Kwinhla Station, Pandaung Township, Bago Division (just north of Yangon ), where MADI also assembled

2760-481: The regulations. Its engine is rated at 80 hp (60 kW; 81 PS)—since that is how the car is homologated in the United Kingdom, Japanese authorities told the importer that its power should remain unchanged. The Japan Automobile Manufacturers Association also self-imposes a speed limit of 140 km/h (87 mph) for kei cars. In a rare example of an overseas mass-produced model being sold as

2820-422: The shrinking passenger kei car market in 1974 and 1976, respectively, although they both maintained a limited offering of commercial vehicles. Sales had been steadily declining, reaching a low of 150,000 passenger cars in 1975, 80% less than 1970 sales. Emissions laws were another problem for the kei car industry in the mid-1970s. From 1973 to 1978, emissions standards were to be tightened in four steps. Meeting

2880-435: The stricter standards, which were to be introduced in 1975, would be problematic for manufacturers of kei cars. This was particularly hard for Daihatsu and Suzuki , which focused on two-stroke engines, and especially Suzuki, a relatively small company whose entire lineup consisted of two-stroke kei cars. Daihatsu, though, had both the engineering backing and powerful connections of their owner, Toyota , to aid them in meeting

2940-447: The time. This goal influenced Japanese automobile manufacturers to determine how best to focus their product development efforts for kei cars or the larger "national" cars. The small exterior dimensions and engine displacement reflected the driving environment in Japan, with speed limits in Japan realistically not exceeding 40 km/h (24.9 mph) in urban areas. Kei cars were not allowed to be driven any faster than 40 km/h until

3000-628: The vehicles are generally too small and specialized to be profitable. Notable exceptions exist, for instance the Suzuki Alto and Daihatsu Cuore , which have been exported consistently from around 1980. The export version of the Suzuki Jimny has become very popular, both in and outside of Japan. Kei cars are both popular with the elderly, but also with youths and younger families because of their affordability and ease of use. Nearly all kei cars have been designed and manufactured in Japan, but

3060-485: The wider public as well as the global market in 2010. The i-MiEV uses a 47 kW (63 hp) permanent-magnet synchronous motor powered by a 16 kWh lithium-ion battery pack. It can charge overnight in 14 hours from home 100-volt mains, or in 30 minutes from quick-charging stations installed at fleet locations. Its range is 100 km (62 mi) as tested by the US EPA , and 160 km (99 mi) as tested by

3120-491: Was 475 kg (1,047 lb) and maximum cargo capacity was 300 kg (661 lb) when first introduced. The Porter Cab (KECA53) was introduced in March 1969. It was a small, cabover pickup truck on a 1,835 mm (72.2 in) wheelbase, equipped with a live rear axle and a 23 PS (17 kW) at 5500 rpm, 359 cc water-cooled, two-stroke two-cylinder. This, the CC , was Mazda's first two-stroke engine. Top speed

3180-499: Was 90 km/h (56 mph). The Porter Cab, with its peculiar cowlings around the headlights carried an instantly recognizable "surprised" appearance. In 1970 new doors were developed, with the original sliding windows exchanged for roll-down items, incorporating a quarter window. A ventilation vent was also added to the front. Like the Porter, the Porter Cab received the Chantez -derived AA engine in April 1973, which offered 30 PS (22 kW) at 6000 rpm, five less than in

3240-521: Was added. Top speed went up from 67 to 79 km/h (49 mph). In October 1966 the B360 received another facelift, giving it a much more modern look. The two-cylinder B600 was one of the first Japanese cars to have an impact in the Indonesian market. The B600, nicknamed "Soap Box" ( Kotak Sabun ) in Indonesia for its square shape, was used by numerous government agencies and public utilities. It

3300-436: Was also applied in addition to the limit on engine size, in response to the ever-increasing power outputs available with turbocharging and multivalve technologies popularized in the late 1980s. Engine technology was also shared with sports bikes , which are designed more for rider enjoyment and less so for fuel economy, going against the idea of small people's cars and putting the kei cars' tax and structural advantages at risk of

3360-440: Was changed too, from light green to white. Like the Porter before it, the Porter Cab was labelled E360 in export markets. When Kei car regulations were changed for 1976, due to shrinking sales in the category, Mazda did not think it a worthwhile expenditure to develop a new, clean 550 cc engine. Instead, they discontinued the Chantez passenger car and the Porter pickup, and began buying Mitsubishi's 2G23 engines to equip

3420-627: Was increased to 550 cc, taking effect from 1 January 1976. The new standards were announced on 26 August 1975, leaving very little time for manufacturers to revise their designs to take advantage of the new limits. Most manufacturers were somewhat surprised by the decision; having expected a 500 cc (30.5 cu in) limit, they had already developed new engines to fit such restrictions. These new engines were quickly introduced, usually mounted within widened bodies of existing models. These interim versions, with displacements ranging between 443 and 490 cc, were "feelers", developed to see if

3480-463: Was only ever sold with van bodywork there. The B600 was a common sight in Indonesia for decades, so common that its V-twin engine has become popular for use in custom motorcycles. Since 2010, the supply of B600 engines has begun to dry up, however, with prices increasing accordingly. In 1972, the B360/600 entered license production in Burma (today's Myanmar ). Mazda's investment consisted of shipping

3540-513: Was produced from November 1968 to April 1976. The car was closely based on the B360 predecessor, but with all-new body panels. This model was briefly assembled in South Africa by Motor Assemblies. 942 examples of the E360 were built there in 1969 and 1970. The initial engine was the carry-over four-stroke, 20 PS (15 kW) 358 cc inline-four from the B360. The engine was changed to

3600-461: Was really intended for private use, thus avoiding the 15.5% excise tax . Efficient, bare bones design meant that the resulting Suzuki Alto was considerably cheaper than any of its competitors, and it set the tone for kei cars for the entire 1980s. Until the excise tax was abolished in 1989, light commercials like the Alto and its competitors nearly completely supplanted the passenger car versions. As
