ELECTRONIC CAR PARTS: 14) MITSUBISHI CARS

by engr. afan bahadur khan

Mitsubishi Motors Corporation (Mitsubishi Jidōsha Kōgyō Kabushiki Gaisha?) is the fifth largest automaker in Japan and the fifteenth largest in the world by global unit sales. It is part of the Mitsubishi keiretsu, formerly the biggest industrial group in Japan, and was formed in 1970 from the automotive division of Mitsubishi Heavy Industries.

Throughout its history it has courted alliances with foreign partners, a strategy pioneered by their first president Tomio Kubo to encourage expansion, and continued by his successors. A significant stake was sold to Chrysler Corporation in 1971 which it held for 22 years, while DaimlerChrysler was a controlling shareholder between 2000 and 2005. Long term joint manufacturing and technology licencing deals with the Hyundai Motor Company in South Korea and Proton in Malaysia were also forged, while in Europe the company co-owned the largest automobile manufacturing plant in the Netherlands with Volvo for ten years in the 1990s, before taking sole ownership in 2001.

Thanks to these alliances it benefitted strongly in the 1970s and '80s, increasing its annual production from 250,000 to over 1.5 million units. But its strong presence in south-east Asia meant it suffered more than most of its competitors in the aftermath of the 1997 East Asian financial crisis, and since then the company has struggled to consistently increase sales and maintain profitability.

History

Mitsubishi's automotive origins date back as far as 1917, when the Mitsubishi Shipbuilding Co., Ltd. introduced the Model A, Japan's first series-production automobile. An entirely hand-built seven-seater sedan based on the Fiat Tipo 3, it proved expensive compared to its American and European mass-produced rivals, and was discontinued in 1921 after only 22 had been built.

In 1934, Mitsubishi Shipbuilding was merged with the Mitsubishi Aircraft Co., a company established in 1920 to manufacture aircraft engines. The unified company was known as Mitsubishi Heavy Industries (MHI), and was the largest private company in Japan. MHI concentrated on manufacturing aircraft, ships, railroad cars and machinery, but in 1937 developed the PX33, a prototype sedan for military use. It was the first Japanese-built passenger car with full-time four-wheel drive, a technology the company would return to almost fifty years later in its quest for motorsport and sales success.

Immediately following the end of the Second World War, the company returned to manufacturing vehicles. Fuso bus production resumed, while a small three-wheeled cargo vehicle called the Mizushima and a scooter called the Silver Pigeon were also developed. However, the zaibatsu (Japan's family-controlled industrial conglomerates) were ordered to be dismantled by the Allied powers in 1950, and Mitsubishi Heavy Industries was split into three regional companies, each with an involvement in motor vehicle development: West Japan Heavy-Industries, Central Japan Heavy-Industries, and East Japan Heavy-Industries.

East Japan Heavy-Industries began importing the Henry J, an inexpensive American sedan built by Kaiser Motors, in knockdown kit (CKD) form in 1951, and continued to bring them to Japan for the remainder of the car's three year production run. The same year, Central Japan Heavy-Industries concluded a similar contract with Willys (now owned by Kaiser) for CKD-assembled Jeep CJ-3Bs. This deal proved more durable, with licensed Mitsubishi Jeeps in production until 1998, thirty years after Willys themselves had replaced the model.

By the beginning of the 1960s Japan's economy was gearing up; wages were rising and the idea of family motoring was taking off. Central Japan Heavy-Industries, now known as Shin Mitsubishi Heavy-Industries, had already re-established an automotive department in its headquarters in 1953. Now it was ready to introduce the Mitsubishi 500, a mass market sedan, to meet the new demand from consumers. It followed this in 1962 with the Minica kei car and the Colt 1000, the first of its Colt line of family cars, in 1963.

West Japan Heavy-Industries (now renamed Mitsubishi Shipbuilding & Engineering) and East Japan Heavy-Industries (now Mitsubishi Nihon Heavy-Industries) had also expanded their automotive departments in the 1950s, and the three were re-integrated as Mitsubishi Heavy Industries in 1964. Within three years its output was over 75,000 vehicles annually. Following the successful introduction of the first Galant in 1969 and similar growth with its commercial vehicle division, it was decided that the company should create a single operation to focus on the automotive industry. Mitsubishi Motors Corporation (MMC) was formed on April 22, 1970 as a wholly owned subsidiary of MHI under the leadership of Tomio Kubo, a successful engineer from the aircraft division.

The logo of three red diamonds, shared with over forty other companies within the keiretsu, predates Mitsubishi Motors itself by almost a century. It was chosen by Yataro Iwasaki, the founder of Mitsubishi, as it was suggestive of the emblem of the Tosa Clan who first employed him, and because his own family crest was three rhombuses stacked atop each other. The name Mitsubishi is a portmanteau of mitsu ("three") and hishi (literally, "water chestnut", often used in Japanese to denote a diamond or rhombus).

1970s

Part of Kubo's expansion strategy was to increase exports by forging alliances with well-established foreign companies. Therefore, in 1971 MHI sold U.S. automotive giant Chrysler a 15 percent share in the new company. Thanks to this deal, Chrysler began selling rebadged Galants in the United States as Dodge Colts, pushing MMC's annual production beyond 250,000 vehicles. In 1976, the Galant was sold as the Chrysler Scorpion in Australia.

A 1973 Mitsubishi Galant

By 1977, a network of "Colt"-branded distribution and sales dealerships had been established across Europe, as Mitsubishi sought to begin selling vehicles directly. Annual production had by now grown from 500,000 vehicles in 1973 to 965,000 in 1978, when Chrysler began selling the Galant as the Dodge Challenger and the Plymouth Sapporo. However, this expansion was beginning to cause friction; Chrysler saw their overseas markets for subcompacts as being directly encroached by their Japanese partners, while MMC felt the Americans were demanding too much say in their corporate decisions.

1988 IPO

A 1982 Mitsubishi Pajero

Mitsubishi Motors went public in 1988, ending its status as the only one of Japan's eleven auto manufacturers to be privately held. Mitsubishi Heavy Industries agreed to reduce its share to 25 percent, retaining its position as largest single stockholder. Chrysler, meanwhile, increased its holding to over 20 percent. The capital raised by this initial offering enabled Mitsubishi to pay off part of its debts, as well as to expand its investments throughout south-east Asia where it was by now operating in the Philippines, Malaysia, and Thailand.

1990s

Hirokazu Nakamura became president of Mitsubishi in 1989 and steered the company in some promising directions. Sales of the company's new Pajero were bucking conventional wisdom by becoming popular even in the crowded streets of Japan. Although sales of SUVs and light trucks were booming in the U.S., Japan's car manufacturers dismissed the idea that such a trend could occur in their own country. Nakamura, however, increased the budget for sport utility product development, and his gamble paid off; Mitsubishi's wide line of four-wheel drive vehicles, from the Mitsubishi Pajero Mini kei car to the Delica Space Gear passenger van, rode the wave of SUV-buying in Japan in the early to mid-1990s, and Mitsubishi saw its overall domestic share rise to 11.6 percent in 1995.

Mitsubishi Pajero

The Mitsubishi Pajero (IPA: /pəˈhɛroʊ, pɑˈxɛroʊ/) is a sport utility vehicle manufactured by Mitsubishi Motors. It was named after Leopardus pajeros, the Pampas Cat which inhabits the Patagonia plateau region in southern Argentina. However, because pajero is a slang term for "wanker" in the Spanish language, alternative names have been adopted for certain overseas markets. It is known as the Mitsubishi Montero (meaning "mountain warrior") in Spain, India, and the Americas (except Brazil), and as Mitsubishi Shogun in the United Kingdom.

Thanks to their success, the Pajero, Montero and Shogun names were also applied to other, mechanically unrelated models, such as the Pajero Mini kei car, the Pajero Junior and Pajero iO/Pinin mini SUVs, and the Mitsubishi Pajero/Montero/Shogun Sport.

History of Mitsubishi Pajero

The first Pajero prototype was unveiled at the Tokyo Motor Show in November 1973. The Pajero II prototype followed in 1978, five years later. Mitsubishi’s aim was to create more of a recreational vehicle, not just an SUV.

In January 1983, the first Pajero made its debut at the Paris Dakar Rally, taking first place in 1985 at only the third attempt. To date, the Pajero is the most successful vehicle in the Dakar Rally. This not only gave the Pajero an offroad reputation, but also helped in the sales department.

First generation (1982–90)

The first generation made its debut at the Tokyo Motor Show in October 1981, and was launched in May 1982. Initially, it was a three-door, short-wheelbase model available with a metal or canvas top and three different engines options:

2.0-litre 4-cylinder petrol (2000/2.0)
2.6-litre 4-cylinder petrol (Astron 2.6)
2.3-litre naturally aspirated diesel (2300 D)
2.3 liter turbocharged diesel (2300 TD/2.3 TD).

It was loaded with features that had previously not been seen on a Japanese four-wheel-drive car: a turbocharged diesel engine, a front double wishbone suspension with torsion bar springs, power steering and suspension seats. This made the Pajero a four wheel drive vehicle which integrated all the amenities of a passenger car.

In January 1983, only a year following its launch, mildly tuned production Pajeros entered the world of motor sport.

The Pajero, however, failed to appeal to everyone. It was seen to be a commercial vehicle, and since it was only available in a short wheel base form, it didn’t really appeal to those with families.

Hence, in February 1983, Mitsubishi came out with a long wheel base, five door model, to serve the needs of a larger target market. The long wheel base model was available with a choice of two different engines; a 2.0-litre turbocharged petrol (badged as "2.0 Turbo" and "2000 Turbo" in some markets) and a 2.3 liter turbocharged diesel (badged as 2.3 TD or 2300 TD). It also came in Standard, Semi-High Roof and High Roof body styles. A stripped down nine-seater version of the High-Roof variant was commonly used in UN Peace Operations.

The long wheelbase model also increased seating capacity to seven, with available third row seats, which could be folded to the sides for additional trunk space or combined with second row seats to form a bed.

The Pajero was further refined in June 1984. The turbo diesel engines now had higher power/torque ratings, whilst the long wheel base models got standard four wheel disc brakes and four way adjustable shock absorbers as standard equipment.

A new flagship model was then introduced in early 1987, with a two-tone paintjob, fifteen inch (38 cm) light alloy wheels, front seat heaters, wool seat covers, genuine leather headrests, a three spoke steering wheel and a sound system with radio/cassette. Also in 1987, a version of the Pajero/Montero was rebadged by Dodge as the Raider, which ran through 1989.

Mitsubishi Montero LS 4-door

Finally in 1988, a 3.0-litre SOHC V6 engine was made available, alongside a 2.5-litre turbo diesel engine, with the first 4x4 intercooler. This translated to better acceleration in mid to high rev ranges. The long wheel base models got a coil link suspension system for better ride comfort and off-road ability.

It was available with a 3-door body for a short wheelbase (SWB) or a 5-door body for a long wheelbase (LWB). Engines included a 2.6 L I4 with 82 kW (110 hp/112 PS), a 3.0 L V6 with EFI and 104 kW (139 hp/141 PS) and a turbocharged 2.5 L OHV diesel I4 with 62 kW (83 hp/84 PS) or an intercooled 70 kW (94 hp/95 PS). Part-time four wheel drive was standard on all models.

The Gen I platform was later built under license by Hyundai Precision Products as the Hyundai Galloper from 1991 to 2003, and exported to Europe for a brief time. While it used first generation mechanicals, the Galloper's body was closer to the second generation Pajeros.

Second generation (1991–1999)

Mitsubishi sold over three hundred thousand Pajeros in 1989 and 1990[citation needed]. However, the time for a redesign was long due and 1991 saw the first Generation II Pajero. Just about everything was now new and further enhanced. A new, larger body was available in four different versions; Metal Top, Canvas Top Convertible, Semi High Roof Wagon and High Roof Wagon (long wheel base). The short wheel base models were stretched by 70 millimeters (2.8 inches) and the long wheel base models by 30 millimeters (1.2 inches). The available engines included a 3.0 liter 12-valve SOHC with ECI-Multi electronic fuel injection and a 2.5 liter turbocharged diesel engine with an intercooler.

The second generation also saw the introduction of Super Select 4WD (SS4) [known as ActivTrak 4WD in some markets] and multimode ABS, which were firsts on Japanese four wheel drives. SS4 was ground-breaking in the sense that it combined the advantages of part time and fulltime four wheel drive with four available options: 2H (high range rear wheel drive), 4H (high range fulltime four wheel drive), 4HLc (high range four wheel drive with locked center differential and 4LLc (low range four wheel drive with locked center differential). Another advantage of this second generation system is that it gave the driver the ability to switch between two wheel drive and fulltime four wheel drive at speeds up to 100 km/h (62 mph), whereas the first generation Pajero had to be stationary to switch from rear wheel drive to four wheel drive (but not from four wheel drive back to rear wheel drive). Multimode ABS, on the other hand, was equally innovative. This meant ABS would be fully functional in all modes of SS4, as braking with a locked center differential requires completely different braking parameters.

In July 1993, two new power plants were introduced; a 3.5 liter 24-valve DOHC with ECI-Multi and a 2.8 liter turbocharged diesel with an intercooler. A new, larger transmission and transfer case was also part of the upgrade.

The Pajero Evolution was introduced in October 1997, which was developed in response to new entry requirements for the Paris – Dakar Rally’s T3 Class. The Pajero Evolution came standard with a 3.5 liter 24-valve DOHC V6 with Mitsubishi Innovative Valve Timing and Electronic Lift Control (MIVEC). A new, dual plenum variable intake helped increase power and a new suspension made the ride even smoother.

In 1998, vehicles destined for General Export and the GCC (Gulf Cooperation Council Countries) received a facelift. Wider fenders, new headlights, grille, bumper, fog lights and sidesteps were all part of the redesign. The wide fenders are often called "blister flare fenders". Driver and front passenger SRS airbags were made standard on models equipped with the 3.5 liter DOHC V6 engine, whilst still remaining optional on GLS models with the 3.0 liter SOHC V6. An upgraded interior wood trim was made available on 3.0 liter GLS and 3.5 liter models. A leather-wrapped or leather and wood trim steering wheel was also made available, alongside an upgraded suspension and steering system. The 3.0 liter 12-valve SOHC engine was now available with a 24-valve configuration. Models without wide fenders remained as base models (GLX), available with a 2.4 liter 16-valve DOHC engine, producing 147 hp (110 kW). The 3.0 liter 12-valve engine was optional on these GLX models, and remained the base engine on the GLS.

The second generation was introduced on January 22, 1991 and manufactured until 1999. It retained the two body styles, but design was rounder and more city-friendly than the previous bulky model. The 3.0 L V6 gasoline engine was retained, now available with a 24-valve head, capable of 136 kW (183 hp/185 PS), while the 2.5 turbodiesel's power was slightly increased to 73 kW (98 hp/99 PS). In 1993, the Pajero was slightly restyled, and larger engines were introduced, a 3.5 L V6 with 153 kW (205 hp/208 PS) and a 2.8 L SOHC turbodiesel rated at 92 kW (123 hp/125 PS). These versions introduced Mitsubishi's Super Select four wheel drive system (known as Active-Trac in the United States), with an electronic transfer shift that could split power between both axles without the need to stop the car. It worked at speeds up to 100 km/h (62 mph).

The first generation Pajero was also marketed as the Hyundai Galloper in Korea, Europe and GCC Countries, while the second generation was in production elsewhere.

This model remains in production in India, whereas the latest generation is sold there as the Montero. And in the Philippines as the Pajero 2.8 Field Master 4x2 alongside with the 4th Generation Pajero. 4X4 Pajero is on production until 1999. It is known to be the only one of its kind among Pajeros worldwide to delete the Super Select 4WD drivetrain. This was accomplished in the year 2000 to avoid taxes slapped on 4 Wheel Drive SUVs imposed by the Estrada Administration. It is still in production in Colombia, with CKD parts (Complete Knock Down), with 2.4l 16 valve SOCH(130PS)and 3.0l 12 valve (148PS) , these engines are available only in hard top 3-door and the 5-door only with the 3.0l engine.

Third generation (1999–2006)

Designed by Pininfarina, the third generation Pajero hit the Japanese Domestic Market in 1999, whilst it was made available to other markets in late 2000 as a 2001 model. The vehicle was completely redesigned, inside and out and had a lower, wider stance. A lower center of gravity meant the Pajero had better on-road handling manners and the newer body had over three hundred percent more torsional rigidity. The biggest change to bring this about was that the Pajero utilized a unibody construction, as opposed to the previous body-on-frame (box-ladder). This also permitted a longer suspension stroke. The fuel tank was also relocated to between the axles for better safety.

The SS4 system was also further refined, as bevel gears were replaced with planetary ones. This meant the front-to-rear torque setting ranged from 33 to 67, with the ability to adjust to 50/50 depending on surface conditions. The system was also made fully electronic, which meant the vehicle didn’t have to be in gear to switch between drive modes. After all the upgrades, the system was renamed to Super Select 4WD II (SS4-II).

Alongside rack and pinion steering (as opposed to the recirculating ball system on previous generations), the Pajero also offered a choice of three transmissions; a five speed manual, a four speed INVECS-II automatic and a five speed INVECS-II tiptronic.

An all-new 3.8 Liter SOHC 24-valve V6 powerplant was also introduced on this generation. This engine utilized an Electronic Throttle Valve (ETV), to deliver a refined cruising power with power to spare for offroad ventures.

The third generation was introduced on August 2, 1999 and was scheduled to be replaced by the Autumn of 2006, having been restyled in 2003. This was the most luxurious of the three generations, moving to a more upscale segment to compete against the Land Rover Discovery, but more importantly, to counter its home rival Toyota Land Cruiser's growth. The 3.0 L engine's power was decreased to 130 kW (175 hp/177 PS), and the 3.5 L engine was given gasoline direct injection, increasing power to 162 kW (217 hp/220 PS) in the Japanese market (export versions kept the standard EFI engine, now with 149 kW (200 hp/203 PS). The 2.8 L Diesel was retained only for developing markets, and was replaced by a new 16-valve direct injection engine, with 3.2 L and 120 kW (161 hp/163 PS).

In the North American market, the 3.5 L engine was replaced for 2003 by a more powerful 3.8 L unit, with 160 kW (215 hp/218 PS). This engine was later made available to a few export markets such as South America and Australia, whilst it replaced the GDI V6 in the Japanese lineup in 2005. The short wheelbase model is not available in North America, where the Montero is the only SUV in Mitsubishi's lineup with standard four wheel drive. Faced with falling sales, the Montero was pulled from the US market after the 2006 model year.

2006-2007 Mitsubishi Pajero VRX (Australia)

2001-02 US-spec Mitsubishi Montero

2003-06 US-spec Mitsubishi Montero

Fourth generation (2006)

The fourth generation was introduced at the Paris Motor Show on September 30, 2006. New interior and exterior styling were accompanied by enhanced safety with dual-stage SRS front airbags as well as new side-impact and curtain airbags. The Super-Select 4WD II system was retained, complemented by an improved Active Stability & Traction Control (ASTC) system and electronic brakeforce distribution.

The engines were upgraded with the 3.2 L Diesel now producing 125 kW (167 hp/170 PS) and the 3.8 L V6 gaining MIVEC variable valve timing to boost power to 184 kW (247 hp/250 PS). Both engines meet new Euro IV emissions standards. The 3.0 L V6 is retained for the Japanese and GCC markets.
