Brawny V8 is Lexus Smooth
The LX 570's new 5.7-liter V8 delivers the punch and pulling power that customers in this segment demand. A real powerhouse in its segment, the powerplant produces 383 horsepower at 5,600 rpm. Peak torque of 401 lb.-ft at 3,600 rpm is a 22-percent increase over the 4.7-liter V8 in the 2007 LX 470 model. The V8's more advanced Dual VVT-i system controls valve timing and overlap on both the intake and exhaust valves, which helps to optimize power, fuel efficiency and emissions.
An Acoustic Control Induction System (ACIS) uses butterfly valves inside the intake manifold to switch 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.
New Suspension Technologies, Added Capability
Lexus LX models have always appealed to customers looking for a full-capability SUV. New upgrades to the suspension and full-time four-wheel-drive system enhance driving comfort and performance, both on- and off-highway. A Four-Wheel Electro-Hydraulic Suspension with Active Height Control (AHC) and Adaptive Variable-air Suspension reacts more quickly and allows for a greater range of adjustment than the system it replaces.
The new suspension system helps improve on-road handling by reducing chassis roll by more than 30 percent. The compression chambers of the shock absorbers are diagonally linked (front-left shock linked to rear right, and front right linked to rear left) by a center control valve. Passing small body motions from front-to-rear increases overall vertical suspension damping.
The Adaptive Variable-air Suspension (AVS) system helps to ensure smooth ride quality for all driving situations. AVS provides four positions to control the shock absorber damping force. Position 2 will suit most driving conditions and will automatically select the appropriate suspension damping in response to driving conditions. Position 1 provides a softer response on bumpy roads. Positions 3 and 4 provide increasingly greater levels of control for driving a heavily loaded vehicle, driving at higher speeds on paved roads, or driving on unpaved roads. When the driver shifts the two-speed transfer case into low range for negotiating steep inclines, AVS automatically selects the suitable damping setting.
Active Height Control (AHC) and New Crawl Control
The revised Adaptive Height Control (AHC) system in the new LX 570 also controls ride height, lowering the chassis by about two inches for entry and exit and returning automatically to its normal height when the vehicle begins to accelerate. For improved aerodynamics, the AHC system lowers the vehicle by nearly one inch in front and by a little more than a half inch in the rear at highway speeds. Finally, when the transfer case is shifted into low range, AHC raises the vehicle by approximately three inches to provide additional ride height in driving situations where chassis clearance is at a premium.
The LX 570 also introduces a new Crawl Control feature for improved throttle modulation when maneuvering over rough or difficult surfaces. When the transmission is shifted into low range, Crawl Control helps maintain appropriately low speeds, making it easier for the driver to maneuver the vehicle safely. Crawl Control also actuates a set of virtual locking differentials to minimize tire slippage and optimize chassis behavior.
Such enhanced chassis control reduces the likelihood of bottoming the LX 570 on the driving surface. Without canceling Crawl Control mode, the driver can reduce vehicle speed by braking, or adjust the crawling speed with a selector switch. A multi-terrain anti-lock braking system is designed to help reduce stopping distances on slippery surfaces such as sand or gravel.
Comprehensive Passive Safety
For enhanced occupant safety, the new LX 570 is equipped with a segment-leading 10 standard airbags, including driver- and front-passenger knee airbags, second-row seat-mounted side airbags and third-row curtain airbags. Active Front Headrests are a first for a Lexus utility vehicle, and the LX 570 also gains second-row seat belt pretensioners and a direct tire pressure monitor system.
The Lexus Definition of Luxury
In addition to its numerous standard features and advanced technologies,
the LX 570 also offers a number of optional amenities including climate-controlled front seats and heated rear seats, a rear-seat entertainment system with a nine-inch screen, the Lexus' Intuitive Park Assist (IPA), a first-in-its-class Pre-Collision System with Adaptive Cruise Control and the Lexus Link
