Innovative Suspension and Technologies

Significant upgrades to the suspension and full-time four-wheel-drive system raise the LX to new levels of driving comfort and performance, on- and off-road. A Four-Wheel Electro-Hydraulic Suspension with Active Height Control (AHC) and Adaptive Variable Suspension is quicker and allows for a greater range of adjustment than the system it replaces. The new cross-linked system allows each wheel to react to the driving surface it is in contact with and also react to the actions of the opposing wheels. Using a valve at each corner and a center or master valve, the cross-linked suspension system detects the extension or deflection of each of the LX 570's 20-inch wheels and counters that with appropriate response at the opposite wheels.

The intelligence built into the LX 570's new suspension senses chassis roll and helps reduce that roll by more than 30 percent. The system also controls ride height quickly, lowering the chassis by an average of two inches for entry and exit and returning automatically to its normal height when the vehicle begins acceleration.

For improved aerodynamics, the new 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, the AHC system 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 will also include a new Crawl Control feature for increased throttle control when maneuvering over rough or difficult surfaces. When in low range, Crawl Control helps maintain appropriate low speeds allowing the driver to concentrate on steering the LX 570 on the desired path. Similar to cruise control in maintaining vehicle speed, Crawl Control also actuates a set of virtual locking differentials to minimize tire slippage and maximize chassis behavior. Because chassis control is significantly improved, the likelihood of bottoming the LX 570 on the driving surface is significantly reduced.

While Crawl Control can be compared in some ways to cruise control, the driver constantly maintains control over the vehicle. Without cancelling the Crawl Control mode, the driver can reduce vehicle speed by braking, or alter the speed higher or lower by adjusting a speed selector switch.

The new LX 570 will also feature a multi-terrain ABS braking system. This new technology is designed to help reduce stopping distances on slippery surfaces such as sand or gravel.

Among its many advanced technologies the LX 570 will also offer a new blind corner monitor feature designed for use in urban settings such as exiting a parking garage. With cameras located within the grille and under the passenger side-view mirror, the driver can easily check hard-to-view areas by simply pressing a button on the dashboard and viewing the camera images on the navigation screen.
