Its products include heavy and medium duty trucks and buses, and light-duty trucks; passenger pickup vehicles, pickup trucks, tractors, and sport utility vehicles; and marine and industrial engines. The company also offers diesel engines to manufacturers in various fields, including construction machinery, agricultural equipment, power generators, and commercial vessels. In addition, it provides after-sales services; repair services of commercial vehicles and buses; and commercial vehicle leasing, and commercial vehicle maintenance contract services. Further, the company manufactures automobile parts and engines. Additionally, it engages in the import, wholesale, supply, and export of vehicles, and components and parts; and warehousing and transportation activities, as well as import, assembly, and wholesale of pickup trucks and derivatives. The company was formerly known as Diesel Automobile Industry Co., Ltd. and changed its name to Isuzu Motors Limited in July 1949. Isuzu Motors Limited was founded in 1916 and is headquartered in Tokyo, Japan.


Isuzu Motors' history began in 1916, when Tokyo Ishikawajima Shipbuilding and Engineering Co., Ltd. planned a cooperation with the Tokyo Gas and Electric Industrial Company to build automobiles. The next step was taken in 1918, when a technical cooperation with Wolseley Motors Limited was initiated, yielding exclusive rights to the production and sales of Wolseley vehicles in East Asia from knock-down kits. In 1919 came the first ever Japan-produced passenger car, a Wolseley model, the Fifteen A9 15/40 ?? at the Tokyo Ishikawajima Shipyard at the Fukagawa Factory. The Wolseley sourced CP truck followed two years later; 550 of these were built by 1927. In 1923 Japan was devastated by the Kanto earthquake which made the fledgling transportation infrastructure that was heavily reliant on government-owned railroads unusable due to the twisted tracks. Heavy construction vehicles were imported from the United States companies GMC and Ford to aid in recovery and reconstruction, and the company sought to contribute by producing locally built construction and heavy duty vehicles. In 1927 the company introduced its 2-ton load capacity "Sumida P-type truck" equipped with an A6 engine and a 1-ton vehicle "Sumida M-type No. 1 bus" equipped with an A4 engine. The name "sumida" was used from the Sumida River as the factory at Fukagawa was close by.

In 1929 IHI Corporation, separated part of its manufacturing business and merged with DAT Automobile Manufacturing Inc. and changed its name to Jidosha Kogyo Co., Ltd. The names used for the products of this company, marketed as "Sumida" and "Chiyoda", have special significance in Japan. Chiyoda is a district in Tokyo where the Imperial Palace is located, and Sumida refers to a river that flows through Tokyo approximately 3.59 km east of the Imperial Palace. In 1934 the Tsurumi Factory opened under company name Automobile Industry Co., Ltd. and in 1937 Automobile Industries was reorganized and formed into a new company, Tokyo Automobile Industries Co., Ltd. and was founded with a capital of ¥1,000,000. The company continued to manufacture heavy duty trucks and passenger busses, realizing the need to modernize the transportation infrastructure of Japan, and was one of the primary manufacturers for the Imperial Japanese Army along with Mitsubishi Heavy Industries, and had a corporate allegiance to the Yasuda Zaibatsu. One of the vehicles it produced for the war effort was the Sumida M.2593 armored personnel carrier. In 1942, Hino Heavy Industries was split off from Tokyo Automobile Industries, becoming a separate corporation. After the Second World War, the company was finally renamed to Isuzu in 1949, following a meeting with the Japanese Government's Ministry of Trade and Industry .


The word Isuzu translated into English means "fifty bells"—hence the focus on "bell" in both the later Bellel and the Bellett. The name was used from the Isuzu River that flows near to the Ise Grand Shrine, one of Japan's most sacred and revered shrines.

Post World War history

Truck and bus production of the TX40 and TU60 series and the Isuzu Sumida bus resumed in 1945, with the permission of the occupation authorities. and has remained the primary focus of manufacture for the company, along with diesel engine production. In 1958 a factory was built at Fujisawa, Kanagawa, and in 1959 the Isuzu Elf was introduced as a medium duty cab over commercial truck which is still in production, and was also shared with the Isuzu Journey bus. Isuzu continued to maintain its market presence by providing commercial vehicles by introducing the Isuzu TY in 1966. The company is one of the primary manufacturers of commercial duty trucks and busses for public transportation, to include the Isuzu Cubic, Isuzu Gala and the Isuzu Erga along with the Isuzu Giga.

Corporate partnerships

Beginning in 1953 the Hillman Minx passenger car is produced under license of Rootes Group giving the company a passenger car to compete with other Japanese manufacturers, realizing that their resources were limited and therefore sought out international partnerships. The Minx remained in production until 1962, after the 1961 introduction of Isuzu's first passenger car, the Bellel, and later the sports coupe Isuzu 117 Coupé. Being a small producer making cars which were somewhat too large and pricey for the Japanese market at the time, Isuzu spent some time looking for a commercial partner. Under pressure from MITI, who were attempting to limit the number of automobile manufacturers in Japan, a cooperation with Fuji Heavy Industries began in 1966. This joint sales-service collaboration was seen as the first step towards an eventual merger. The Subaru 1000 was even shown in Isuzu's 1967 annual vehicle brochure, as a suitable complement to the larger Isuzu lineup. This tie-up was over by 1968, when an agreement with Mitsubishi was formed. This ended even more quickly, by 1969, and the next year an equally short-lived collaboration was entered with Nissan. A few months later, in September 1971, what was to prove a more durable capital agreement was signed with General Motors.

Linking with General Motors

While the company had a long relationship with GM going back to the 1920s, the first investment of GM taking a 34% stake in Isuzu was seen in 1972, when the Chevrolet LUV became the first Isuzu-built vehicle to be sold in the United States. To symbolize the new beginning, Isuzu also developed a new logo for 1974, with two vertical pillars as stylized representations of the first syllable in ??? . In 1974 Isuzu introduced the Gemini, which was co-produced with General Motors as the T-body Chevrolet Chevette. A modified version was sold in the United States as Buick's Opel by Isuzu, and in Australia as the Holden Gemini. As a result of the collaboration, certain American GM products were sold to Japanese customers through Isuzu dealerships. Holden's Statesman was also briefly sold with Isuzu badging in Japan during the seventies. Isuzu exports also increased considerably as a result of being able to use GM networks, from 0.7% of production in 1973 to 35.2% by 1976; this while overall production increased more than fourfold in the same period. As a result of the GM joint venture, Isuzu engines were also used by existing GM divisions .

In 1981 Isuzu began selling consumer and commercial vehicles under their own brand in the United States. The Isuzu P'Up was the first model sold to consumers as an Isuzu, rather than as a Chevrolet or Buick, along with the Isuzu Piazza sports car. Isuzu's then president Toshio Okamoto then initiated a collaboration with small-car expert Suzuki to develop a global small car for GM, the S-car. A three-way agreement of co-ownership was signed in August 1981, with Isuzu and Suzuki exchanging shares and General Motors taking a 5% share of Suzuki. Following on from this, in 1985 Isuzu and GM established the IBC Vehicles venture in the United Kingdom, producing locally built versions of Isuzu and Suzuki light vans ; to be sold in the European market under Vauxhall's Bedford brand. During this period Isuzu also developed a worldwide presence as an exporter of diesel engines, with their powerplants in use by Opel/Vauxhall, Land Rover, Hindustan, and many others. Two Isuzu model lines were marketed as part of the Geo division when it was initially launched as a Chevrolet subsidiary. In the domestic Japanese market, OEM deals with other manufacturers were entered to aid the poorly performing passenger car arm. It led to the badging of Suzukis, beginning in 1986, and Subaru small commercial vehicles as Isuzus . This OEM tie-up occurred alongside the establishment of SIA , an American joint venture with Fuji Heavy Industries . Shortly afterwards, the Lafayette, Indiana plant became operational.

Contraction begins

Isuzu ended US sales of the Impulse in 1992, and the following year it stopped exporting the Stylus , the last Isuzu-built car sold in the US.

In 1993 Isuzu began a new vehicle exchange program with Honda, whereby Honda sold the Isuzu Rodeo and Isuzu Trooper as the Honda Passport and Acura SLX, respectively. In return Isuzu began selling the Honda Odyssey as the Isuzu Oasis. Thus, Honda's lineup gained two SUVs, and Isuzu's lineup gained a minivan. In the Japanese market, the Gemini was now a rebadged Honda Domani and the Aska was a Honda Accord, while Honda received the 2-door MU as the Jazz and the 4-door Trooper as the Horizon.

Isuzu's United States sales reached a peak in 1996 after the introduction of the Isuzu Hombre pickup, a badge-engineered GM truck . Isuzu resurrected the beloved Amigo in 1998, before changing the name of the 2-door convertible to Rodeo Sport in 2001 in an attempt to associate it with the better selling 4-door Rodeo. The new Axiom launched in 2001, with the fictional salesman Joe Isuzu from 1980s advertising campaigns brought back to promote it. Isuzu sales began to slide due to the aging of the Rodeo and Trooper, and poor management and a lack of assistance from GM. The Rodeo Sport was discontinued in 2003, while production of the Rodeo and Axiom ceased a year later. By this point sales in North America had slowed to just 27,188, with the discontinued Rodeo and Axiom making up 71% of that total.

In 1998 GM and Isuzu formed DMAX, a joint venture to produce diesel engines. GM raised its stake in Isuzu to 49% the following year, effectively gaining control of the company, and quickly followed this up by appointing an American GM executive to head Isuzu's North American Operations. This marked the first time a non-Japanese executive had held such a high position at Isuzu. In 2001 GM and Isuzu announced plans to share distribution networks and for Chevrolet to market an Isuzu product.

The production version of the VehiCROSS was introduced to the US in 1999, but met with mixed reviews, as its high pricetag, unique styling and two-door configuration did not seem to meet with market demands. Production of the VehiCROSS and other sport utility vehicles, including the Trooper, ended in 2001 as part of a major financial reorganization which eliminated almost 10,000 jobs. GM had been pushing the company to focus exclusively on producing commercial vehicles and engines.The number of Isuzu dealerships in the US began a rapid decline, and by 2005 had only 2 models: the Ascender and the i-series pickup truck . At this point, Isuzu in the US was primarily a distributor of medium duty trucks such as the N-series, sourced both from Japan and US plants in Janesville, Wisconsin and Flint, Michigan. Isuzu had 290 light-vehicle dealers in the US in August 2006, and sold an average of just two Ascenders per dealer per month, and rumors of Isuzu's withdrawal from the US market were rampant. Plans to introduce a new Thai-built SUV for 2007 were shelved when Isuzu Motors Limited decided that a new SUV would be too risky, instead proceeding with the launch of the i-series trucks. Despite extremely low sales figures of 12,177 passenger vehicles for 2005 , Isuzu Motors America announced its first profit in years, mainly due to restructuring cuts.

In early 2002, Fuji Heavy Industries bought Isuzu's share of Lafayette, Indiana plant, and Subaru Isuzu Automotive became Subaru of Indiana Automotive. After 8 years of heavy Honda Passport sales and light Isuzu Oasis sales, Honda and Isuzu cooperatively ended their vehicle exchange agreement in 2001. The Oasis was dropped, and Honda replaced the Passport with the Pilot. 2001 was Isuzu's last year for passenger vehicles in Canada, as Isuzus in Canada were mostly sold at Saturn-Saab dealerships. In late 2002 Isuzu initiated a recapitalization and debt-for-equity conversion plan to stave off a bankruptcy. GM acquired 20% of DMAX, 60% of Isuzu Motors Polska and Isuzu Motors Germany, and the rights to three types of diesel engine technology from Isuzu. by paying 50 billion yen . GM also paid 10 billion yen for a 12% stake in the recapitalized company. GM wrote off its investment in Isuzu in 2001.Production of the 7-passenger Ascender ended in February 2006 with the closure of GM's Oklahoma City Assembly plant, leaving Isuzu with the 5-passenger Ascender, built in Moraine, Ohio and the low-selling i-Series as its only retail products. The company sold just 1,504 vehicles in North America in the first two months of 2006. GM ended its equity investment in Isuzu and sold all its shares to Mitsubishi Corporation, Itochu and Mizuho Corporate Bank; both GM and Isuzu claimed the companies would continue their relationship, but there was no word as of April 12, 2006 on the effect this would have on DMAX operations.

In June 2006 Isuzu and GM agreed to establish a joint venture called "LCV Platform Engineering Corporation " to develop a new pickup. Isuzu said it would use its engineering expertise to develop the pickup and GM would develop derivatives based on the integrated platform. Mitsubishi Corp became Isuzu's largest shareholder in October 2006, after it converted all the preferred shares in Isuzu it had held since 2005 into common stock, increasing its shareholding from 3.5% to 15.65%.In November 2006 Toyota purchased 5.9% of Isuzu, becoming the third largest shareholder behind Itochu and Mitsubishi Corporation, and the two companies agreed to study possible business collaboration focusing on the areas of R&D and production of diesel engines, related emissions-control, and other environmental technologies. In January 2007 Isuzu and General Motors updated the LCV range with a 3.0 litre common rail diesel engine that had far more torque and power than its predecessor. In August 2007 Isuzu and Toyota agreed to develop a 1.6-liter diesel engine for use in Toyota vehicles sold in European markets. At this point, details of development, production and supply of the diesel engine were still under discussion, but in principle, Isuzu would play the leading role, with production scheduled to begin around 2012.

On January 30, 2008 Isuzu announced its complete withdrawal from the US market, effective January 31, 2009. It would continue to provide support and parts. The decision was due to lack of sales. Some of the lack of sales was blamed on consumer experiences with low quality engines and service. Isuzu had been experiencing a slow decline since the late 1990s. In less than 10 years, they had gone from selling a complete line of cars, trucks, and SUVs, into being a specialized SUV maker, and finally selling only a pair of rebadged, General Motors Trucks. The company continued to sell commercial vehicles in the US.Isuzu and Toyota shelved development of a clean diesel engine in December 2008.On January 29, 2009, Isuzu and GM announced that they were in talks to transfer the operation of the medium-duty truck production line in Flint, Michigan to Isuzu for a five-year period. In June, however, GM announced that these talks failed to reach an agreement, and GM instead ceased production of the Chevrolet Kodiak and GMC Topkick vehicles on 31 July 2009.In July 2016, Isuzu and Mazda agreed to collaborate to produce the next-generation pickup trucks for Mazda outside of North America.Reese Counts . "Mazda and Isuzu to collaborate on a new pickup truck". Autoblog. As a result, the third-generation Mazda BT-50 is built by Isuzu in Thailand since 2020.

Isuzu’s plant in the Indian state of Andhra Pradesh began operations in 2016.In August 2018, Toyota sold off its 5.9% stake in Isuzu.In December 2019, Isuzu announced that it had signed a non-binding memorandum of understanding which would eventually see Volvo sell UD Trucks to them. In November 2020, the companies announced that they have signed the "final agreements", making the memorandum of understanding binding. In April 2021, Isuzu completed UD Trucks acquisition.In March 2021, Isuzu, Hino, and Hino's parent Toyota announced the creation of a strategic partnership between the three companies. Toyota acquired a 4.6% stake in Isuzu while the latter plans to acquire Toyota shares for an equivalent value. The three companies said they would form a new joint venture by April called Commercial Japan Partnership Technologies Corporation with the aim of developing fuel cell and electric light trucks. Toyota would own an 80% stake in the venture while Hino and Isuzu would own 10% each.

The ISUZU brand is also getting future-ready with renewed focus on product innovation, engineering excellence and customer support.

Isuzu Motors' vision is to remain at the forefront of innovation and technology and be the leader in providing best-in-class customer experiences.
