2009 Lexus LX 570

Lexus introduced the all-new, more powerful, more capable and more luxurious LX 570 premium luxury utility vehicle for 2008. A new optional Luxury Package and other enhancements for 2009 help keep this luxurious eight-passenger model at the top of its segment.

New semi-aniline leather-trimmed seating and Bubinga wood trim give the LX 570 an even more luxurious look and feel inside. A new cool box for beverages adds convenience, and a new SmartCard key enhances vehicle security. Elegant exterior design is accented for 2009 with new liquid graphite finish for the standard 20-inch wheels and a new exterior color, Costa Azul Mica.

Engine/Transmission/Drivetrain/Performance
The LX 570's 5.7-liter V8 delivers the punch and towing power demanded in this segment. The new, high-tech powerplant produces 383 horsepower at 5,600 rpm and peak torque of 403 lb.-ft at 3,600 rpm. Crucial to LX customers who tow with their vehicles, 90 percent of peak torque is available at just 2,200 RPM.

The V8's advanced Dual 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. Tubular stainless steel headers flow into a full stainless steel exhaust system.

The LX 570's six-speed automatic transmission is designed to handle high torque while performing with Lexus quietness and smoothness. The electronically-controlled transmission's control unit estimates road conditions and predicts the driver's intention to select the appropriate gear ratio for the vehicle's speed and the driving conditions. A sequential shift mode allows the driver to select gears manually. Even at very low speeds, such as trail driving, the transmission operates smoothly and imperceptibly.

The LX 570's transfer case provides full-time four-wheel drive that is equally adept at handling the rigors of slippery winter weather or deep mud or snow. A 2.618:1 low-range ratio is available for challenging driving surfaces. The system uses a TORSEN® limited-slip locking center differential to distribute power 40:60 front-to-rear, directing more power to the wheels with the best grip should slippage occur. Four-wheel Active Traction Control (A-TRAC) employs both brake and throttle intervention to help control wheel spin. Vehicle Stability Control (VSC) helps maintain directional control during cornering and can be disengaged via the “Trac off” switch.

The Crawl Control feature provides improved throttle modulation when maneuvering over rough, uneven or difficult surfaces. When the transmission is shifted into low range, Crawl Control regulates engine speed and output, along with braking force, to propel the vehicle forward or in reverse at one of three low-speed settings. Crawl Control also actuates a set of virtual locking differentials to help reduce tire slippage and optimize chassis behavior.

Without canceling Crawl Control mode, the driver can reduce vehicle speed by braking or adjust the crawling speed with a selector switch. Hill-start Assist Control (HAC) provides additional control for off-road driving by helping to keep the vehicle from rolling back while starting on a steep incline or slippery surface.

Chassis/Body/Suspension/Tires/Brakes
The LX 570's highly capable chassis is equipped with an advanced suspension system. Body-on-frame construction provides ruggedness and durability in extreme driving conditions, plus impressive towing capability and ride isolation characteristics. Towing capacity is 8,500 pounds. An electro-hydraulic system with four-wheel Active Height Control (AHC) and Adaptive Variable Suspension (AVS) reacts more quickly and allows for a greater range of adjustment than the system used in the previous LX model.

Applying advanced computer aided engineering and lightweight components, engineers developed an all-new frame structure that uses lightweight, high-strength steel. Deeper, wider frame longitudinal members help to provide enhanced safety. The new frame was tested over some of the worst roads in Australia, plus desert areas of the U.S. and other parts of the world in conditions where other SUVs could not go. The body utilizes welded high-strength sheet steel, especially in the A-, B-, C- and D-pillars and in the rocker area to reduce weight and increase rigidity.
