Toyota Land Cruiser
The Toyota Land Cruiser remains unique in the market, an iconic and luxurious, full-size SUV imbued with undeniable go-anywhere capability and the safari-conquering spirit of its world-famous forbears. Also unique is the way the eight-passenger Land Cruiser has evolved from a basic four-wheel-drive utility vehicle into an upscale vehicle without compromising its roots – and that is the root of its loyal following.
The latest in Toyota’s “connected” and telematics technologies help ensure that the Land Cruiser can provide its driver and passengers with safety, security and convenience.
The Land Cruiser’s 5.7-liter DOHC V8 engine produces 381 horsepower at 5,600 rpm and 401 lb-ft of torque at 3,600 rpm. Ninety percent of peak torque is available at just 2,200 rpm, helping make the Land Cruiser an outstanding tow vehicle. The Land Cruiser uses regular-grade (87 AKI) gasoline and is ULEV-II certified.
The V8's advanced dual independent Variable Valve Timing with intelligence (VVT-i) system controls valve timing and overlap on both the intake and exhaust valves, which helps to optimize power, fuel efficiency and emissions. The Acoustic Control Induction System (ACIS) switches the length of the intake tract in two stages, based on RPM and throttle angle, to improve torque across the engine speed range. Stainless steel exhaust manifolds flow into a full stainless steel exhaust system. A water-cooled oil cooler helps control oil temperature while towing.
The Land Cruiser’s six-speed automatic transmission is designed to handle high torque while performing with luxurious smoothness. Fourth gear is direct drive, and both fifth and sixth gears are overdrive ratios. The transmission's control unit estimates road conditions to select the appropriate gear ratio for the vehicle's speed and driving conditions. A sequential shift mode allows the driver to select gears manually.
The Land Cruiser’s body-on-frame construction provides ruggedness and durability in extreme driving conditions, plus impressive towing capability and ride isolation characteristics. The front of the frame features a three-stage crush structure, so frame damage to other areas of the vehicle is minimized in the case of frontal impact.
The high-mount double-wishbone front suspension system uses gas-pressure shock absorbers, a hollow stabilizer bar, and coil springs. This system provides a high level of off-road driving capability and suspension control while maintaining outstanding on-road driving comfort. Approach and departure angles are 30 degrees and 20 degrees, respectively. At the rear, the reliable and proven four-link, coil-spring with lateral rod format provides a long suspension stroke and also features gas-pressure shock absorbers and a hollow stabilizer bar.
The Kinetic Dynamic Suspension System (KDSS) adjusts the lean resistance provided by the front and rear stabilizer bars. KDSS may reduce maximum body-sway angle by as much as 50 percent to help enhance both on-road handling response and off-highway capability. By using hydraulic cylinders acting on each stabilizer bar and linked by a pressure-sensing valve, KDSS reduces the degree of sway stiffness provided by the stabilizer bars in response to changing road conditions and driver inputs.
In off-road driving situations, KDSS allows the wheels on each axle to move with a larger degree of side-to-side independence, helping to minimize any tendency for wheel lift. During cornering, when both front and rear cylinders are compressed, no fluid is flowing in the system, and the stabilizer bars work conventionally to help reduce body lean. When an uneven surface is encountered, one compressed cylinder causes fluid to flow between the front and rear cylinders, allowing the stabilizer bars to move freely. This action increases wheel articulation and travel and also helps to equalize wheel loading. By allowing the stabilizer bars to disengage in certain situations, the nominal stiffness of the bars can be notably increased, thereby reducing body lean and improving handling without negatively affecting ride comfort or off-road performance.
