The Toyota automobile industry was in a fateful crisis from Japan's defeat in war and the chaos that followed it. However, military procurement enabled a recovery and the combination of the accumulation of technology from before the war and present material resulted in the development of an automobile above expectations.
The chassis of the Toyota Jeep BJ was based on the SB-type 1-ton truck (with an S-type 995cc engine) that was originally released in 1947. For that reason, at 2,400mm the wheelbase about 200mm longer than that of the Jeep, and the body was also a size larger.The SB-type compact truck was commonly known as the Pony Toyota (and later the Toyopet Truck), and because it was designed as a small transport vehicle that could also double as a passenger car, its suspension settings were likewise soft. These characteristics were carried over into the Toyota BJ-type, so it gave a surprisingly comfortable ride.The engine was a 3,386cc water-cooled in-line 6-cylinder B-type gasoline engine. Jeeps being built at that time had a side valve construction, but the B-type engine was an OHV type. The engine was originally designed in 1937, with the first prototype completed the next year in 1938, after which it was installed in the GB-type truck, the KB-type truck, and the BM-type truck, being primarily an engine for 4-ton class trucks.
The Toyota Jeep BJ was completed in 1951, and first unveiled that same year at a public showing of Toyota vehicles. There were 26 Toyota vehicles displayed at this event, and during the 3-day period the attendance amounted to some 200,000 people. Moreover, the design of the Crown was begun in 1952, with the first Crown model built in 1955. At the time it was considered unusual to say the least to match a 4-ton truck engine with a compact truck chassis, but in reality these were the only materials that Toyota had to work with. It turned out to be a successful combination. An ample sized body useful for transporting materials driven by an engine with power to spare, this model met multiple needs in the market for a compact 4x4 vehicle at a high level.
Production Period was from 1955-1960

The development theme for the 20-series was a new style with more driving comfort. As a result, it didn't have much in common with the Toyota BJ, instead showing more soft lines in the body styling. These major changes in the chassis frame created a basic design, which through the transition to the 40-series remained unchanged for 29 years.To improve the riding comfort first the springs in the suspension were changed. The leaf springs in the front and rear were lengthened and the number of plates reduced to 4 to create a softer cushion. In addition, rubber bushings were added to the pivot and shackle in order to dampen the vibration transmitted to the cabin. Moreover, the inner channel of the side frame was extended, and the number of closed structure members was increased. The frame itself was strengthened so that the vibrations from the suspension would be absorbed rather than transmitted to the body.
Appearance of the First Real Station Wagon Production Period was from 1967 - 1980
The 40 series had three different body lengths all with the same face as uniqueness is a necessity for a utility vehicle with typical users that desire a sense of prestige. That was the reason why the long body FJ55V was given an exclusive vehicle body.
The First Transfiguration in 30 Years : Production Period was from 1980's
The pressure from the preceding model sales volume was enormous. However, the 70 series was able evolve the Land Cruiser while maintaining the images of rigidity, reliability, and durability of the past. Without major alterations to the basic structure, many small details that pioneered the path to modernization were added on.

In 1984 a new 70-series was born, bringing to a close a long era of 29 years (including the 20-series) during which the 40-series remained virtually unchanged.There were limits to what could be done to modernize the old design of the 40-series model. For this reason Chief Engineer Masaomi Yoshii introduced a complete overhaul in the design, producing the 70-series to lead the Land Cruiser with a new generation.The first pre-condition however was that the new Land Cruiser was not to sacrifice any of its toughness, so a strong ladder frame was outfit with rigid leaf springs. The body plates were thickened by 1.0mm for added strength. While leaving something of the image of the 40-series, such as externally added fenders, it was also given modern features such as curved glass. As before there were two body types available, the short BJ70 (soft top and van), and the middle BJ73 (FRP top).In 1985 a derivative of the BJ70 model was added, the LJ71G, which had a 2L-T-type engine (4-cylinder, 2,446cc, 85PS, 19.2kgm). As indicated by the letter G, this model was registered as a passenger car type wagon. It had a soft appearance in the front mask, and the suspension had rigid coil springs. In the export model it was known as the Light Land Cruiser, or the Land Cruiser II. Moreover, this was the same engine that was installed in the 4 Runner.

Later the Land Cruiser shifted its weight to the 60-series. In competition to outdo its rival model the Pajero in terms of luxury, the 60-series evolved into the 80-series. During this period the 70-series tended to fade into the background.Then in 1990 a significant minor change was introduced in the 70-series, when two newly developed engines were introduced; the 1PZ-type engine (replacing the 3B-type with an OHC 5-cylinder, 3,469cc, 115PS, 23.5kgm engine specs), and the 1HZ-type engine (replacing the 13B-T with an OHC 6-cylinder, 4,163cc, 135PS, 28.5kgm engine specs). Moreover, to the middle length model a new ZX grade was added. Both the PZJ70 short and the HZJ73 underwent modifications.Following that in the same year the 70-series wagon underwent a complete makeover. In addition to the original 2-door, a 4-door semi-long was introduced, the name was changed to the Prado, and with other design changes it took on its own unique identity. The 4-door model had 3 rows of seats and could carry 8 people. Compared to the 70-series that was registered as a commercial vehicle, it now had more potential reclassified as an RV. The 2L-T-type was transformed with electronic controls in the new 2L-TE-type engine, which gave it improved performance. With the minor change the short version kept its LJ71 number, while the long version was renamed the LJ78. At this time also appeared a 4-door semi-long, with a choice of two engines the 1PZ or the 1HZ, named accordingly the PZJ77 and the HZJ77.
Surpassing Its Rivals : Production Period was from 1996 - 2002
Demand for a 4WD with easy-to-ride characteristics naturally grew with the enhancement of user types experienced during this particular time. Gaining momentum from these demands, the Mitsubishi Pajero began to aggressively expand its market share. That was the main reason for the introduction of the 90 series Prado.

In 1999 there was a fairly significant minor change introduced, with changes in the front grille, front bumper, door trim, combination meter design, and the addition of multi-reflector headlamps. In addition an Optitron meter was added, along with other luxury upgrades. Even in the mechanisms options were added which could deliver high-performance on unpaved or muddy roads, such as Active Traction Control (TRC) and Vehicle Stability Control (VSC), as well as the option for A/T in most grades.In 2000 a newly developed diesel engine was introduced, the 1KD-FTV-type common rail type direct-injection engine with intercooler (DOHC in-line 4-cylinder, 2,982cc, 170PS, 35.9kgm specs). This was also a response to current demands for lower fuel consumption, cleaner gas emissions, less noise and vibration. Moreover, at this time also an engine immobilizer was added to all grades of the Land Cruiser as standard equipment, reflecting the problem of rising car thefts in Japanese society.
The 90-series Prado shares the same chassis platform as the 185-series 4 Runner, but the frame has greater durability than that of the Surf. The side frame on the Prado is constructed of fully closed cross-section members, and the inner channels which this forms are made of thicker steel plate. The inner channel is made of steel plates inside the side frame that reinforce and strengthen the entire frame.The front section of the frame has the first independent suspension ever put on a Land Cruiser. Beyond this, of the 2 upper and lower arms, the upper arm is mounted in a higher position than the usual type, which strengthens the overall resistance of the suspension to horizontal G force.Along with major changes to the suspension, the 90-series also introduced a newly developed 5VZ-FE-type gasoline engine. This 3.4-liter V6 DOHC engine with numerous technical improvements made to the cylinder heads was also more compact and lighter weight. Bringing the two camshafts closer together reduced the relative angle of the intake and exhaust valves, and as a result it was possible to create a pent roof type combustion chamber with less heat loss. Moreover, this engine was tuned for higher performance in the low- to mid- rpm range making it easier to handle.The diesel engine in the 90-series was inherited from the 1KZ-TE-type engine of the 70-series Prado. Thanks to its compact turbo charger and air-cooled intercooler, this engine got improved output, better fuel consumption, and lower emissions. In addition, with the balance shaft and reinforced durable cylinder block there was also less noise and vibration.As the 90-series developed new variations were added to the lineup, and more offroad 4x4 mechanisms were added. To cope with increased vehicle weight a new 4-cylinder 3RZ-FE-type gasoline engine was selected, and the 1KZ-FE-type diesel engine was replaced with a direct fuel injection 1KD-FTV-type that has greater output, lower fuel consumption, and cleaner emissions. Moreover, Active TRC was added to the drive train, which helped maintain constant delivery of drive force by automatically applying the brakes to any tire that began to spin when driving on uneven ground, enabling you to take full advantage of the existing traction in the other tires. This made the Prado both safer and more aggressive at the same time
The Path to Prestige : Prodction Period was from 1989 to 1998
The concept of the 80 series was the combination of "Advanced" and "Top Quality" features at the highest level.However, the true reason why the 80 series gained worldwide attention was the fact that it able to maintain its original toughness of excellent off-road characteristics while being loyal to the above.

In 1989 regular minor changes were introduced, all in the direction of greater luxury, which led eventually to the evolutionary transformation of the ever-popular 60-series into the new 80-series.At the time the 60-series was being driven more for leisure or family use, and as a town car, than as an offroad vehicle. Over time the demand increased for more fashionable and passenger car like characteristics. The response to this market demand was the 80-series Land Cruiser.The aim of the 80-series was to be both at the forefront of technology and luxury. Along with passenger car like styling in the front design, wide tires and large fenders gave it a bold effect, looking something like a luxury battleship that could cruise the land. It was a break from the tradition of the Japanese 4x4. Moreover, accommodations remained for offroad applications, such as space in the instrument panel to install wireless communications equipment, and a rail for mounting a roof carrier.It was large at 5 meters length and 2 meters wide, with 3 types of engines to choose from; the 3F-E-type gasoline engine, the 1HD-T-type direct-injection diesel turbo engine (4,163cc, 165PS, 37.0kgm), and the 1HZ-type diesel engine. For all but one type of model in the series, it came with rigid coil springs in front and rear, and a full-time 4x4 power train. Of course the top of the line van and wagon offered a VX Limited grade.In 1992 the original 3F-E-type engine was replaced in the new model FZJ80G with a 1FZ-FE-type gasoline engine (DOHC in-line 6-cylinder, 4, 476cc, 215PS, 38kgm specs). In 1995, the HDJ81V was added to the lineup, and the 1HD-T-type diesel engine took on 4-valves in the 1HD-FT-type engine (4,163cc, 170PS, 38.7kgm specs). In addition a camper style model called Active Vacation was added to the lineup, which was registered in a low tax and low maintenance bracket
The transition from the 60-series to the 80-series was more drastic than that from the 50-series to the 60-series. A number of new technologies were introduced, and it was more of a revolutionary change than an evolutionary one.The only engine that was kept on as it was from the 60-series was the 3F-E-type, while the diesel 1HD-T and the 1HZ-type that had also been used in the 70-series underwent major improvements not only in power but also in reduced noise and vibration, making it a new generation diesel engine. The new engine design included thicker cylinder walls with reinforced ribs, thoroughly researched through computer analysis. Moreover, the cylinder head cover and other parts that did not need to be reinforced were replaced with resinous parts, enabling the new engine to be stronger, lighter, and more compact at the same time.The 80-series lasted for about 9 years, during which both the gasoline and the diesel engines evolved. The gasoline engine progressed from the 3F-E type to the 1FZ-FE-type, which was a DOHC with 4 valves on each cylinder. The diesel engine progressed from the turbo spec 1HD-T-type to the 1HD-FT-type, which was also a 4-valve per cylinder type.In the power train, the transfer gained a central differential, and all but one grade had a full-time 4x4 system. A switch on the instrument panel enabled you to go from 2WD to high-range 4WD, while a lever on the floor enabled you to directly shift into LO range 4WD. This so-called HF2A transfer had electronic controls for locking the central differential when you wanted to, so that according to ground conditions even in part-time 4x4 mode you could drive effectively on bad roads. Moreover, there was also a maker option for an electronic differential lock mechanism on the front and rear axle, which enabled you to travel even further on bad roads.In the suspension, leaf springs were replaced with coil springs in front and rear. This maintained strong durability, while at the same time improving driving comfort and steering stability. There were 3 arms supporting the axle in the front, and 5 in the rear. Each arm had rubber bushings on the pivot portion, which were designed to provide strong axle support as well as reduce shocks and vibrations coming from rough road surfaces. The overall result was improved riding comfort
Aiming to be The World's Best : Production Period was in 1998
The 100 series debuted despite no apparent loss in popularity of the 80 series prestige SUV (Sports Utility Vehicle) which was at the pinnacle of its success. The luxuriousness even above the 80 series was aimed at being the world's top level and became an instant success
The Land Cruiser 100-series has not only reached the top of the Land Cruiser series, but has actually come to represent the pinnacle of all offroad 4x4 vehicles, and is outfit with a full range of high-level mechanisms. Among these is AHC & Skyhook TEMS, truly the King of 4x4 systems. AHC stands for Active Height Control, which enables you to maintain a constant height of the vehicle, regardless of the load or number of passengers you are carrying. When driving offroad on ground with rough spots, the vehicle height can be raised to prevent the underside of the car from hitting or scraping the ground.The Skyhook TEMS mechanism electronically adjusts the damping force of the shock absorbers appropriately according to ground conditions, and this system both makes for a more comfortable ride and improves handling stability. A soft suspension makes a more comfortable ride, but the problem is that it also tends to increase instability and feels unsettled. Stiff suspension settings provide more stability, but make the ride also feel stiff and unpleasant. Skyhook TEMS overcomes these respective limitations and gives you the best of both worlds.The addition of a 2UZ-FE-type V8 gasoline engine was just right for a luxury 4x4. This engine was a scaled up version of the 4-liter V8 1UZ-FE-type engine that Toyota used in its luxury passenger model the Celsior (known overseas as the Lexus LS400). For its installation in the Land Cruiser 100-series its aluminum alloy cylinder block was made more durable by using a steel compound. Moreover, the brake system was tuned, and the engine was modified to give it higher performance in the mid- to low rpm range, befitting the heavy body that the engine had to move.For the diesel engine in the series, the 1HD-FT-type that had been used in the 80-series was given refinements, and a high-pressure compact electronically controlled direct-injection fuel pump and intercooler were added. Thus the 1HD-FTE-type engine was created, with improvements in power, fuel consumption, and emissions. Along with the direct-injection fuel pump, the injection nozzle was improved, which resulted in greatly reduced noise and vibration. The 2H-type engine had been used in the 60-series. This was the original predecessor of the 1HD-FTE-type engine that carried the Land Cruiser diesel engine into the next century

A Full model Change for the First Time in Six Years: Production year 2002
The theme for this full model change was "NEW TRADITIONAL 4WD". The outstanding driving ability succeeded through the generations was further enhanced together with also pursuing excellent onroad running ability

Continuing the tradition of the preceding 90 Series, the Land Cruiser underwent a full model change in 2002 with further enhanced outstanding drivability under grueling conditions. The quality of the interior and exterior has also been thoroughly refined for a pleasant onroad driving experience that looks set to create a new legacy in the Land Cruiser Prado tradition.In terms of performance, the front suspension features an independent double wishbone structure while the rear adopts a 4-link axle suspension. A newly designed and exclusive high rigidity frame provides superior maneuverability and running stability while also offering a comfortable ride. The new Land Cruiser not only evolves offroad driving characteristics, but also fully enhances its onroad driving performance.In addition to the adoption of a new frame, the effective placement of sound reducing and absorbing material and the new flush body surface result in quiet road, wind, and engine noise on par with a medium-high class passenger sedan.Newly developed Torsen LSD (Limited Slip Differential) is used for the center differential and distributes 40:60 front/rear basic driving force with automatic and instant adjusting to ideal distribution of front and rear torque according to road conditions for enhanced tracability during turning. This has resulted in superior onroad driving as well as superior traction in slippery conditions such as on icy roads. In addition, an active TRC (TRaction Control system) independently controls braking at all four wheels with a active wheel speed sensor semiconductor for superior control when climbing and descending. Furthermore, DAC (Downhill Assist Control) enhances vehicle stability when descending steep slopes, while Hill start assist control depresses vehicle rearward motion when climbing steep slopes.

For the exterior, the Toyota design keywords of "Vibrant" and "Clarity" have been successfully carried over to this full-fledged 4WD vehicle. While maintaining the Land Cruiser's functional and dynamic shape, the design goal was for a clean and long-lasting design. Inheriting the unique characteristics of the strong presence of 5-door models and a vibrant feel of the 3-door models, this new model has a Land Cruiser Prado look while also adding next-generation appeal with vertically oriented headlamps and front grilles, and a cabin shape consisting of flowing surfaces. The length, width, and wheelbase have been increased while the height has been kept down for an extremely stable yet rugged look
THE TOP OF THE FOOD CHAIN: Production year 2008
