The tough, mid-size, V8-powered GX gets a major upgrade this month as the new GX 460. Experienced GX drivers, take note: KDSS has been enhanced, as there’s an array of new off-road technologies:
Crawl Control: Although this available system is new to the 2010 GX, Lexus unveiled Crawl Control two years ago in the Lexus LX. Think of it as a sort of cruise control for more extreme off-road situations. On steep slopes or uneven terrain, the system automatically works the throttle and brakes to help keep the vehicle steadily moving forward, sensing when one wheel might spin and then compensating by applying more torque to another. The driver’s job? The driver can concentrate on steering. > View demo
Multi-Terrain Select: A Lexus-first, this available GX system allows drivers to put the vehicle in one of four terrain modes: Mud & Sand, Loose Rock, Mogul, or Rock. Depending on the mode selected, the GX’s Vehicle Stability Control (VSC) computer applies selective braking and optimal drive torque for superior traction.
Multi-Terrain Monitor: Another Lexus first, the available Multi-Terrain Monitor gives 2010 GX drivers navigation-screen views of the areas just around the vehicle, thanks to four cameras. One shows the low-front surroundings, one shows the rear surroundings, and two others show the side areas next to the tires. The system kicks on automatically at slow speeds, such as when squeezing through tight spaces (drivers can toggle through each view via a steering-wheel control).
KDSS Upgrade: The 2010 GX 460 also gets an upgrade to its Kinetic Dynamic Suspension System (KDSS), the award-winning suspension technology that debuted with the vehicle in 2004. KDSS is a stabilizer system that helps optimize traction in off-road situations, while providing minimized body “lean” when on the highway. The upgrade: the system now electronically controls the effect of each stabilizer to optimally match current terrain to help provide even better handling. > View demo
Safety Systems: The 2010 GX 460 offers a host of advanced safety and driver-support technologies, including Dynamic Radar Cruise Control, AFS (Adaptive Front-lighting System), the Pre-Collision System (PCS), and Lane Keep Assist, a system that can recognize certain lane markers and warns the driver if he or she is about to unintentionally deviate from the lane.
Interior: For 2010, think genuine leather upholstery trim on all three rows of seating. The eight-way power adjustable front seats include heating, ventilation, and power lumbar support; the driver’s seat also features a multiple-driver memory function. The second row features a versatile 40:20:40 split seatback; the outer seats are heated, and all of them recline. Models with the seven-seat option have a power flush-with-floor third row seat: with the push of a button, the third row headrests collapse and the seat automatically folds flush with the floor, helping optimize cargo-carrying capacity.
Body-on-Frame Construction: A last note on 2010 GX quality. While many premium SUV competitors are moving toward the car-like unibody construction, the redesigned GX remains a body-on-frame vehicle, meaning the body is attached to a single rigid frame (found in vehicles that require strength). In addition to its better durability, body-on-frame construction has proven superior in suppressing road noise and vibration—which translates to a more peaceful interior cabin.
 The GX 460 is designed to meet most off-road driving requirements, but off-roading is inherently dangerous. Abusive use may result in bodily harm or damage. Lexus encourages responsible operation to protect you, your vehicle and the environment. Seatbelts should be worn at all times.
 Dynamic Radar Cruise Control is designed to assist the driver and is not a substitute for safe and attentive driving practices. Please see your owner's manual for important instructions and cautions.
 The Pre-Collision System is designed to help reduce the crash speed and damage in certain frontal collisions only. It is not a collision-avoidance system and is not a substitute for safe and attentive driving. System effectiveness depends on many factors, such as speed, driver input and road conditions. Please see your owner's manual for further information.
 Lane Keep Assist is designed to read the lane markers of certain roads and apply slight torque to the steering wheel to help keep the car in the center of the lane. It is not a collision-avoidance system and is not a substitute for safe and attentive driving. System effectiveness depends on many factors. Please see your owner's manual for further information.
