Why is Toyota successful? (The Toyota Production System)

Toyota is known for its reliable cars among the general public, but it has also been known in management and leadership circles for its unusual use of people. While most companies tend to make employee policies around the idea that people are lazy and expensive, at Toyota, labor strife is rare and people are an integral part of the quality process. The company’s only strike was in 1950, and resulted in a commitment to mutual trust.

Many credit Toyota’s success to aspects of the Toyota Production System, established by Taïchi Ohno and Shigeo Shingo from the late 1950s through 1970 (when it gained the name). It includes aspects of Jidoka, just-in-time production, and kaizen, reducing both inventories and defects. The system is used worldwide, but is only one of the reasons for Toyota’s success.

Jidoka is not letting a defect go from one machine to the next, particularly in automated machinery; essentially, it adds the ability to detect unacceptable quality during the process of production rather than waiting until the end, when it may be hidden. The name itself is a Japanese pun on the term “automation,” adding the character for a person into the middle. Jidoka was actually implemented by the Toyoda power looms before Toyota was created. Jidoka both reduces costs and increases reliability.

Just-in-time production is the principle of having parts ready just as they are needed, rather than maintaining inventories across an assembly plant and in warehouses. Most writers tend to focus on the cost savings from having less capital tied up in inventory under this system, but there is another advantage: engineering changes (to increase reliability or functionality, or to cut cost) can take effect much more quickly, since stockpiles of parts do not need to be cleared out; and problems with individual parts can be detected much more quickly since they are used closer to the time they are made.

The system was partly a result of Ohno and Shingo's observations of American production. They looked at Ford with an objective eye, and saw problems with Ford's treatment of people as machines at best, and enemies at worst. (Ford, at that time, had a hired army complete with spies which would invade workers' homes to make sure they were living as good Christians, and beat them if they were suspected of union sympathies or were caught in the wrong place at the wrong time.) Quite aside from the humanitarian issues which were perhaps inevitable in a company founded by a man idolized by Adolph Hitler, Ford did not use the knowledge or expertise of its workers. Toyota would lead the world in that regard.

Ohno and Shingo also read the works of American and Japanese management experts, including Ishikawa, Deming, and Juran. They were impressed by the statistical quality control and quality circle approaches. Years before Pehr Gyllenhammar was to turn Volvo around, using similar techniques, Toyota organized around team development and cellular manufacturing. Using people as people, rather than ornery machines, also allowed for more flexibility than Ford's more automated approach would allow. This was to make rapid changes easier, also helping quality and increasing responsiveness to competitors.

Those who are interested in the original work of Taiichi Ohno and Shigeo Shingo may be interested in Ohno's work, Toyota Production System.

Toyota Avalon


The Toyota Avalon is a uniquely American project, with industry people suggesting that a number of ex-GM engineers were involved in lengthening the Camry, upgrading its interior, and improving its ride to create the Avalon; all Avalons are made in the United States (Kentucky), even those exported to other parts of the world, where they are not quite as popular, due to their size and thirst. (The Camry is considered large in most areas, but is seen as merely mid-sized in the United States.) The Avalon was the first Toyota to be classified as a ‘domestic’ vehicle, according to CAFE standards.

Toyota Avalon

Our experience with the first-generation Avalon was admittedly limited. We liked the straight-line acceleration, while finding the cornering ability to be far below many similarly sized cars - particularly the Eagle Vision and Dodge Intrepid - and while we found the interior to be surprisingly and gratifyingly quiet, the dashboard, which appeared to have been taken straight from an early-1980s Chevrolet, seemed out of place.

Indeed, the Avalon didn’t take off when first introduced; it looked like a long, wide Camry, which was what it was, and the plain interior didn’t help.

Completely redesigned for model-year 2000, the 2001-2006 Toyota Avalon was styled at Toyota’s Calty Design Center in Newport Beach, Calif. The next generation would take hints from the Crown Victoria around the grille, from the Lincoln in the rear, and from Buick in the dashboard, while dropping all visual cues linking it to the Camry. It had a single engine, a 3.0-liter V6 engine with Variable Valve Timing (VVT-i) for excellent fuel efficiency and lower emissions. The engine produces 210 horsepower at 5,800 rpm and 220 lbs./ft. of torque at 4,400 rpm. Estimated fuel economy is 21 mpg city and 29 mpg highway. The engine also contributes to NVH reduction through the use of a new electronically controlled Active Control Mount (ACM) that is designed to reduce engine idle vibration. The sole transmission is a four-speed electronically controlled automatic overdrive transmission with intelligence.

Camry owners could be surprised to see those of the Avalon. The cruise control was on the steering wheel, and there was a large trip computer section in the middle of the car (optional on the lower trim line). The instrument layout was completely different.

The Avalon was the first Toyota to officially be classified as a "domestic" vehicle for CAFE standards. The width increased by an inch, the front seat was moved up an inch, the roof moved up an inch, and the rear seat went back and up by an inch. At the same time, the instrument panel moved up four inches. The overall effect is American-style space; not quite Intrepid, but Impala size at least.

The center console included warning lamps, the odometer and trip meter, clock, and outside temperature. The XLS version included a compass, trip computer, and calendar. Dual climate control was new to the Avalon for 2000, with vents for rear passengers on XLS models with bucket seats. An integrated dust and pollen filter was optional. The sound system went up to 120 watts, with a standard CD and cassette player.

The Avalon's handling still reflected its Camry base: not bad, but not exceptional, either. The ride was very nice with little road noise.

Independent MacPherson strut front suspension and independent dual-link rear suspension with MacPherson strut are complemented by increased body stiffness and refined tire and suspension tuning. The comfortable ride of the second generation Avalon was accompanied by better cornering - admittedly still not top of class, but a far more acceptable compromise given the gentle ride.

Second-generation Toyota Avalon safety features include skid control, traction control, and Brake Assist is available as an option on XLS models. Vehicle Skid Control, or VSC, utilizes the braking system to help the driver maintain control in adverse driving conditions. The system’s traction control feature helps reduce tire slippage during acceleration. The Brake Assist feature detects emergency braking and applies supplemental line pressure to help maximize the effectiveness of the Anti-Lock Brake system (ABS). The rear-view mirror was also made larger. The body design helps absorb energy along predictable paths, helping to lessen intrusion into the passenger compartment. Within the vehicle, there is energy absorbing material in the roof rails, front pillars and center pillars; and an in-trunk release handle for 2001.

The Avalon's cab-forward styling, steep windshield angle, rounded A-pillars, thicker glass, and recessed wiper blades all contribute to a significant reduction in wind noise. The Avalon uses injection molded rocker-trim and a foam underbody coating to help prevent "stone pecking” noise.

The Avalon XL has a trip meter, clock, and thermometer in the instrument panel; the Avalon XLS adds a compass, instant fuel economy, average speed, average fuel economy, trip time meter, fuel range meter, and and calendar. A dual climate control system provides independent heating, ventilation and air conditioning (HVAC) temperature adjustment between driver and passenger. On XLS bucket seat models, the system includes ventilation outlets for the rear seat occupants. Standard on the Avalon XLS, and available as a dealer-installed option on the XL, is an HVAC-integrated micron dust and pollen filter system.

Other comfort and convenience features include:

* Illuminated entry system
* One-touch auto-down/auto-up driver's window with jam protection
* Standard universal remote garage door opener (XLS only)
* Available one-touch power tilt/slide moonroof with jam protection
* Dual double sun visors with extensions
* Power door locks with auto-lock function

The standard audio system includes a 3-in-1 combination of CD, cassette and AM/FM receiver with 120 watts of power. The premium grade audio was developed in conjunction with JBL and includes exceptional high and low frequency extension and clarity. This is achieved by adopting a separate five-channel, 250-watt amplifier. The system includes 3-in-1 functions with an available integrated six-CD changer on XLS models.

Further comfort and convenience features include front and rear cupholders, the large center console bin includes a 12-volt power point and a socket is incorporated for easy charging and storing of a cellular phone. An optional 115-volt A/C outlet - - capable of powering small electronic devices - - is located behind the center console on bucket seat models and on the instrumentation panel on bench seat models. A locking pass-through door behind the fold-down rear seat armrest allows long items like skis to be easily transported inside the vehicle.
Mergers and acquisitions

In 1966, Toyota acquired Hino, which built trucks; commercial trucks from Toyota still carry the Hino name. Hino is currently gaining in popularity in Europe, and is the sales leader for medium and heavy-duty diesel trucks in Japan. After building its first truck as far back as 1913 (when it was part of Tokyo Gas), what had been the truck division of Tokyo Gas (and which was now called Diesel Motor Industry Company) split off its commercial truck and diesel engine division into Hino; the remaining part of the company would become Isuzu. Hino did build standard cars for a time, using designs licensed from Renault, but stopped in 1967 to concentrate on heavy trucks (and avoid competing with the rest of Toyota). Hino currently makes a wide variety of heavy trucks and buses, and was involved in designing and/or producing the Tacoma, T100, 4Runner (HiLux Surf), Sequoia, and Tundra.

In 1967, Toyota took control of Daihatsu (founded in 1907 as Hatsudoki Seizo Co., Ltd), but Toyota did not actually buy the whole company until 1999. Daihatsu sold cars in the US from 1988 to 1992, with their Charade and Rocky making almost no impact; when Toyota bought into the company, it made a three-wheeled car and military four-wheel-drive vehicles. Daihatsu sold vehicles based on Toyotas, along, possibly, with its own designs; their small cars and four wheel drive vehicles have a following. Daihatsu supplies vehicles and major components to other automakers, and appears to be popular in South America.

Denso was not acquired, but was simply spun off of Toyota after World War II; it was once Toyota’s electrical component division. It currently is a roughly $26 billion business with over 100,000 employees and over 170 subsidiaries, selling parts to many major automakers including American companies.
Toyota Motor Corporation today

In April 2002, Toyota adopted the 2010 Global Vision, a vision for meeting mobility needs in a way that respects our earth and all people. It is made of long-term policies centered on the basic theme of 'innovation into the future.' Four key themes based on trends seen as developing from 2020 to around 2030 are:

* Toward a recycle-oriented society
* Toward the age of IT and ubiquitous networks
* Toward a mature society (the decline of nationalism and war and the rise of respectful exchange of ideas)
* Toward motorization on a global scale (societies with little private transport gaining more)

These are linked to the pursuit of a new global image for Toyota with four key components: kind to the earth, comfort of life, excitement for the world, and respect for all people. The encompassing motto of "innovation into the future" is "working with passion and dedication to create a prosperous society."
Who runs Toyota now?

As of March 2007:

* Hiroshi Okuda, Chairman. Born in 1933 - about the same time as Toyota itself - Hiroshi Okuda has been a member of the Board of Toyota Motor Corporation since 1982, and has been the Chairman of the Board since 1999. Mr. Okuda was the president of Toyota from 1995 to 1999, and is also a director of KDDI Corporation. Hiroshi Okuda joined Toyota in 1955, at about the time of the company's entrance to the United States market. He mainly worked in Toyota's international operations, and oversaw preparation of manufacturing plants in North America. He graduated from Hitostubashi University with a degree in business, and has a black belt in judo.
* Fujio Cho, President. Born in 1937 - not long after Toyota itself - Fujio Cho helped to speed Toyota's decision-making but cutting the number of board members in half, appointing three non-Japanese managing officers, and generally streamlining the management structure. He graduated from the University of Tokyo in 1960 and became a production specialist, mentored by none other than Taiichi Ohno. He opened the first Toyota-owned factory in America in 1988. He is a third dan in kendo.
* It is worth noting the martial arts experience of the two top Toyota leaders. Martial arts require discipline, patience, and study; American leaders tend to be lawyers and accountants with experience in obfuscation and penny-watching.
* Akio Toyoda. Son of Shoichiro Toyoda, Akio, born in 1957, helped to get Toyota out of a Chinese joint venture gone bad and into a deal with China FAW Group; started a Web-based retailing venture in Japan; and is currently executive vice president in charge of purchasing, quality, product management, IT, and transport. Akio has been known to reinforce Toyota’s global standing, taking the company beyond its Japanese roots, and has been emphasizing styling and performance in the company’s vehicles.

Some past leaders:

* Eiji Toyoda (president, 1967-1982), who kept Toyota on a low profile even as the company rapidly expanded and dramatically increased its quality and its rustproofing capabilities
* Shoichiro Toyoda (president, 1982-1992), who spread Toyota's manufacturing plants through the world and brought Toyota’s technology to the forefront, surpassing Honda and just about every other automaekr, while increasing reliability even further

History of Toyota City

Toyota City sprung from Koromo Town, a thriving silkworm center in the late 1800s and early 1900s. As the demand for raw silk fell, the city declined, until in 1934 it invited the newly formed Toyota to center there. The name was changed from Koromo to Toyota in 1959. The population is now 25 times its 1930 level, at 350,000.
Toyota and the environment

Toyota is fairly well known for having the best-designed hybrid-electric car, the Prius, which former Chrysler engineer Evan Boberg claimed in 2004 was the only car that actually saved fuel because of its hybrid design rather than coincidental features (such as lighter weight, efficient tires, and such). But Toyota's commitment goes much further. Their Australian unit's Earth Charter notes four principles:

* Contribution towards a prosperous 21st century
o Aim for growth that is in harmony with the environment, and to challenge achievement of zero emissions throughout all areas of business activities and set as a challenge the achievement of zero emissions throughout all areas of business activity.
* Pursuit of environmental technologies
o Pursue all possible environmental technologies, developing and establishing new technologies to enable the environment and economy to coexist harmoniously.
* Voluntary actions
o Develop a voluntary improvement plan, not only based on thorough preventative measures and compliance laws, but one that addresses environmental issues on the global, national and regional scales, and promotes continuous implementation.
* Working in co-operation with society.
o Build close and cooperative relationships with a spectrum of individuals and organisations involved in environmental preservation including governments, local municipalities as well as with related companies and industries.

No environmental statement is meaningful unless it is actually followed - which is one reason why many are so angry at Ford, which made many brash promises, yet continued to push gas mileage downwards and fought even the slightest changes in Federal fuel economy requirements in the US. In Australia, and probably elsewhere in the world, Toyota has a balanced scorecard which notes specific outcomes and measures of environmental action, and uses a plan-do-check-act cycle to carry them out.
Lexus luxury cars join the Toyota stable

While Toyota built good near-luxury cars, sales of the Cressida and Crown were not especially strong, especially given the brisk trade in Corollas and Camrys. In the 1980s, when Toyota seriously looked at its lagging luxury sales, Lincoln and Cadillac had both fallen from grace; Lincoln was relegated to the limousine and car-service trade, and Cadillac had destroyed its reputation with the 4-6-8 engine and the barely-disguised Cavalier clone, the Cimarron. Chrysler had started to plunge downmarket in the 1970s, and Lee Iaccoca was already erasing any prestige the brand had by making thinly disguised Chrysler versions of entry-level Plymouths. Mercedes' quality was fairly low, Audi was suffering from the "unintended acceleration" debacle, and, in short, the competition was in tatters. It was time for Toyota to create both a luxury car and a luxury brand to sell it with — the luxury brand mainly because Americans had become accustomed to brands with relatively narrow ranges (GM had no less than five brands to reach different markets; Ford and Chrysler both had three.)

In the early 1980s, the F1 Project and assigned to an engineering team of 1,400 engineers, 2,300 technicians, 60 designers, and 220 support people under the leadership of Shoiji Jimbo and Ichiro Suzuki. Market research for the Lexus name in the United States started in 1985, with Shoiji Jimbo attending focus groups and interviewing dealers. The first running prototype appeared in July 1985, with an astounding 450 running prototypes built as Lexus spared no expense to beat Mercedes and other luxury marques - which it did, decisively. In 1986, tests were conducted on public roads in the US and Germany. Finally, in 1987, the final design was approved after eight presentations to management.

The LS400, the first Lexus, finally appeared in 1989. It was an immediate hit thanks to its high levels of luxury and reliability, at a lower cost than Mercedes' far less reliable and luxurious models; the low ebb of the competition also helped Lexus to make a splash. Lexus would remain the leader in passenger car comfort and reliability through to the 21st century, though sales of other models - particularly the IS - lagged.
Modern times

Toyota instituted a three year, 36,000 mile bumper to bumper warranty starting in 1988.

Scion was begin in the early 2000s, starting with three cars based off the platform of the old Echo (but brought up to date and refined), with two engines - a small one for the xA and xB, and a 2.4 with an added 50 or so horsepower for the sporty tC. Scion sales were immediately strong in the early-introduction states, leading to a nationwide (United States) launch that, with very little advertising, was still remarkably successful. Like most cars aimed at younger people, the Scions did not attract the younger buyers Toyota was hoping for, at least not in as large numbers as they wanted; but it still brought in a more youthful mix than Toyota or Lexus. Analysts suggested that Scion was brought in mainly because Toyota buyers were growing older, on average, with new Toyotas meant to attract younger audiences (MR2, Celica, Matrix) largely failing to achieve the goal of transforming Toyota's image as a vendor of dull but reliable and comfortable Camrys and Corollas.

Toyota participates in community activities, sponsoring educational and cultural programs as well as research.

Today, Toyota is the world's third largest manufacturer of automobiles in both unit sales and in net sales. In the United States, Toyota has roughly double the sales of Honda, and is edging out Chrysler Group to be the #3 seller. It produces over 5.5 million vehicles per year, equivalent to one every six seconds

It is worth noting that, while German automakers tend to use symbols and numbers, and Americans tend to throw away names frequently, Toyota sticks by a name as long as a car is successful, and doesn't toss names onto cars that don't fit them. The Land Cruiser started in 1950; the Corolla in 1966; the Celica in 1970; the Camry in 1983; the 4Runner in 1984. Notable "dropped" names include the Corona (with its tendency to die from severe rust), Cressida (dropped for the introduction of Lexus in the US), unpopular pickups (T100, HiLux, Compact Pickup), and minivans (Van, Previa).
An era of rapid expansion: post-war Toyota history

In December 1945, Toyota was given permission by the United States military to startup up peacetime production. Toyota Motor Corporation had learned from the American War Department’s industrial training program, which worked on process improvement and employee development; the program, abandoned in 1945 by the United States, lived on in Japan as Taiichi Ohno built kaizen and lean manufacturing around it. (From globalspec).

After World War II, Toyota was kept busy making trucks, but by 1947 it began making the Model SA, called the Toyopet, a name to stay with Toyota for decades, albeit attached to different cars. The Toyopet was not powerful and had a low top speed – 55 mph from a 27 horsepower engine – but it was designed to be cheap, and to handle the rough roads of postwar Japan. In the five years the SA Toyopet was made, 215 were made. The SD may have been more successful; this taxi version saw 194 copies in just two years. The SF Toyopet was the first truly popular Toyota car, with a modified engine (still putting out 27 horsepower) and a taxi version. An RH model with a 48 horsepower engine came out shortly after By 1955, Toyota was making 8,400 cars per year; by 1965, 600,000 cars per year.

In addition to all these cars, Toyota started producing a civilian truck named the Land Cruiser. Styled like Jeeps, the original Land Cruisers were, according to Schreier, based heavily on the legendary Dodge half-ton weapons carrier as well as the Bantam (predecessor of the Jeep) They used a bigger engine than the Jeep (their Chevrolet-clone six) and a size and configuration more like the Dodge weapons carrier, whose capacity it shares (one half ton).

Starting in 1955, Toyota produced its first luxury car, the Crown, powered by a four cylinder, 1.5-liter engine with a three-speed column shift, followed by the 1-liter Corona; only 700 cars per month were made in 1955, but this rose to 11,750 in 1958, and 50,000 per month in 1964.
The start of Toyota's international sales

Toyota started selling cars in the United States in 1958, importing the Land Cruiser and Toyopet. While neither sold well, the margins on the Land Cruiser were better, and the Toyopet was withdrawn while Toyota designed a car specifically modified for the American market – a strategy which later gave us the Avalon and Camry.

In 1959, the company opened its first plant outside Japan - in Brazil. From that point on, Toyota maintained a philosophy of localizing both production and design of its products (that is, adapting vehicles to the places they will be used, as well as building them there). This builds long-term relationships with local suppliers and local labor. Part of this also means that Toyota does not merely build vehicles overseas, but also designs them there, with a network of both design and R&D facilities in North America and Europe.

The first Americanized Toyota — the Tiara, otherwise known as the Toyota Corona PT20 — came out in 1964. The six-passenger car had a 90 gorss-horsepower engine (probably about 60-70 bhp net); it could reach 90 miles per hour, and was comfortable inside. One year later, the Corona was added at under $2,000; it offered an automatic and factory air as options, very unusual in imported small cars at the time (as was the engine's horsepower rating). Sales hit 6,400 in 1965, and reached 71,000 by 1968, nearly doubling each year until by 1971 Toyota was selling over 300,000 vehicles per year, a far cry from 1964's 2,000. Toyota itself was very small in the late 1950s by world standards, and in 1963 was the 93rd largest non-American corporation in the world — but in 1966 was already 47th (in that time it went from being the 9th largest Japanese corporation to the 6th largest, and for that matter the tenth largest auto manufacturer in the world — it would steadily move up to the #3 position and will soon challenge Ford for #2). In 1967, the Corona sold for a reasonable $1,760 - a little below the smallest Big Three sedans — with a good balance of performance, gas mileage, and comfort.

By 1967, Toyota had become well established in the United States, albeit as a niche player. The Corona four-door sedan was seen as competing mainly against the Volkswagen Beetle, though this was hardly fair to the modern Corona, with its relatively large interior space and relatively comfortable ride. The Corona was known from its early days for quality as well as a low price, though rust was a serious problem until the late 1970s, causing more than one Corona to simply rust in half before it became old enough to have mechanical problems.

Toyota introduced another new car to the US in 1967: the Crown, available as a wagon or a sedan. The semi-luxury car boasted a brand new 137 cubic inch in-line six-cylinder engine delivering 115 horsepower (gross) at 5,200 rpm; that is a bit more than the biggest Plymouth slant six but less than the smallest American V8. The engine was small but had seven main bearings, tuned induction, semi-hemispherical heads, and was built with lightweight alloys. The Crown came with a four-speed manual (at the time three speeds were normal) or a two-speed automatic (though most Americans were used to three speed automatics). One unusual feature was standard three-point seat belts, not to mention reclining bucket seats. The Crown was never a big seller but it certainly did better than many foreign cars in the segment; the sedan sold for $2,635, the wagon for $2,785. (Torque was 127 lb-ft at 3,600 rpm, bore and stroke 2.95 x 3.35, 8.8:1 compression, single two-barrel carb. The Plymouth slant six started at 170 cubic inches by comparison, and delivered 115 hp with 155 lb-ft of torque; the 225 cubic inch slant six put out 145 hp, 215 lb-ft.) The Crown was noted for its road manners, smooth ride, and quiet interior.

Soon, Toyota brought to the US the famous but rare 2000GT, which resembled a British sports car with a massive hood and nearly no cabin or trunk. The car had set 16 world speed and endurance records by 1966, with a dual overhead cam six-cylinder engine (150 hp, 121 cid) and five-speed manual transmission. A specially made convertible version was featured in You only live twice. The 2000 GT had surprisingly slow 0-60 times of over 10 seconds, but cornering apparently made up for it, and the quarter-mile went by in a decent enough 15.9 seconds (about the same as a 1995 Neon). Not quite a muscle car, but it probably handled better than the best Detroit had to offer. Toyota also had a variety of trucks for sale in the late 1960s, as detailed in our various truck pages (see the top-of-page menu).

The Corolla, to be America’s favorite small car, was first imported in 1969, two years after its first Japanese production, followed by small pickups that earned a strong reputation for reliability and durability.
Toyota corporate history

The official Toyota history is, like that of most companies, fairly glossy and bare-bones. An article by Konrad Schreier, printed in the Complete Book of Toyota (a bit of a misnomer since the book is mainly a bunch of reprints of then-current, gushing, “no criticism allowed” car reviews), brings up a large number of missing pieces - as does The Standard Catalog of Imported Cars.

Why Toyota and not Toyoda?

According to a much-quoted article in Wikipedia, the spelling change was made to make it easier to pronounce, symbolize a separation from the founder’s home life, and, possibly most importantly, because Toyota, which takes eight strokes to write in Japanese, is considered to be luckier than Toyoda.

Sakichi Toyoda, a prolific inventor, created the Toyoda Automatic Loom company based on his groundbreaking designs, one of which was licensed to a British concern for 1 million yen; this money was used to help found Toyota Motor Company, which was supported by the Japanese government partly because of the military applications. The Japanese relied on foriegn trucks in the war in Manchuria, but with the Depression, money was scarce. Domestic production would reduce costs, provide jobs, and make the country more independent. By 1936, just after the first successful Toyoda vehicles were produced, Japan demanded that any automakers selling in the country needed to have a majority of stockholders from Japan, along with all officers, and stopped nearly all imports.

Toyoda's car operations were placed in the hands of Kiichiro Toyoda, Sakichi Toyoda’s son; they started experimenting with two cylinder engines at first, but ended up copying the Chevrolet 65-horsepower straight-six, using the same chassis and gearbox with styling copied from the Chrysler Airflow. The first engine was produced in 1934 (the Type A), the first car and truck in 1935 (the Model A1 and G1, respectively), and its second car design in 1936 (the model AA). In 1937, Toyota Motor Company was split off.

From 1936 to 1943, only 1,7,57 cars were made – 1,404 sedans and 353 phaetons (model AB), but Toyoda found more success building trucks and busses. (Some of these early details are from http://www.geocities.com/toyotageek/) The Toyota KB, a 4x4 produced starting in 1941, was a two-ton truck similar to the prewar KC; it had a loading capacity of 1.5 tons and could run up to about 43 mph. The GB was based on the peacetime, 1.5 ton G1 truck, which in turn was based on the Model A1 cars. (From globalspec).

The first Toyoda truck was roughly a one-ton to one and a half-ton design, conventional in nature, using (after 1936) an overhead valve six-cylinder engine that appears to have been a clone of the Chevrolet engine of the time: indeed, a large number of parts were interchangeable, and Toyoda trucks captured in the war were serviced by the Allies with Chevrolet components. There was also a forty-horsepower four cylinder model, very similar to the six cylinder in design but rather underpowered for a truck with a full ton of capacity.
