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 off-road 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 off-road 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.

The transfer lever extending from the center console is about the only thing that tells you this Land Cruiser 100 is a serious 4x4 and not a passenger car. It also has more luxury outfittings than the 80-series did. It comes with an option for a DVD navigation system with EMV (Electro Multi Vision) in the center panel.

The upper luxury grade comes with an option for genuine leather seats. The 100-series does not have overfenders, but the wide body means more space on the inside as well.

The chassis of the 100-series has independent suspension in the front, and a completely different structure from the 80-series with built-in collision safety features. However, the 100-series made for the Australian market (105) has rigid coil springs in both front and back, and uses the same chassis from the 80-series.

The double wishbone type front suspension is designed to improve both riding comfort and handling stability. The wheel stroke is not large, but the suspension has durability on a par with the rigid type.

The rear suspension is a 5-link rigid coil structure like that of the 80-series. Improvements in the position of the links made the ride more comfortable. There is also an option for differential lock on the rear axle.

The 4.7-liter V8 2UZ-FE-type gasoline engine is a scaled up version of the 1UZ-FE-type engine used for the Celsior (LS400). It boosts the most powerful engine specs of the entire line to date, with a maximum output of 235PS/4,800rpm, and a maximum torque of 43kgm/3,600rpm.

The 1HD-FT-type engine from the 80-series was upgraded to an electronically controlled 1HD-FTE-type, a turbo diesel engine with mostly improvements on emissions. It produces an output of 205PS/3,400rpm and a torque of 44kgm/1,800rpm.
