The capable GX 460 transitions into the 2012 model year with minimal changes. The standard model receives color-keyed bodyside molding with a chrome accent, while the Premium model now features a high-gloss wheel finish. In addition, the Fire Agate Pearl exterior replaces Peridot Mica.
The GX 460’s fuel economy is better than other V8 luxury utility vehicles and competitive with some six-cylinder models with its EPA-estimated 17 mpg combined, 15 mpg city and 20 mpg highway ratings.
The 4.6-liter V8 is teamed to a six-speed electronically controlled automatic transmission with sequential shift. The responsive powertrain is quiet and helps the GX 460 tow up to 6,500 lbs.
The standard full-time four-wheel drive uses an electronically controlled transfer case and a TORSEN® torque-sensing limited slip center differential which can be electronically locked. It also offers a low range for off-road driving. The TORSEN differential distributes power 40:60 under most driving conditions and changes the ratio as needed based on wheel slip.
The ability to change to a 30:70 ratio during steering maneuvers helps enhance vehicle tracking through curves. If the rear wheels spin, the center differential can change the ratio to 50:50 to help control the slippage. The TORSEN differential also helps make the GX 460 less prone to slippage caused by sudden changes in road-surface conditions, such as driving through a puddle or over an ice patch.
The GX 460 has robust body-on-frame construction and does not compromise on- or off-road performance; the high-strength chassis and dynamic suspension control technology support both.
The power rack-and-pinion steering system helps make it easier to maneuver the GX 460 in tight spaces. Available Adjustable Height Control (AHC) enhances the vehicle’s flexibility in a wide range of driving situations.
By adjusting sway resistance provided by the front and rear stabilizer bars, standard Kinetic Dynamic Suspension System (KDSS) can help reduce maximum body-lean angle by as much as 50 percent to help enhance both on-road handling response and off-highway capability.
Using hydraulic cylinders acting on each stabilizer bar and linked by a pressure-sensing valve, KDSS reduces the degree of roll stiffness provided by the stabilizer bars in response to changing road conditions and driver inputs. Because KDSS changes the effectiveness of the stabilizer bars in certain situations like off-road driving, the nominal stiffness of the bars can be notably increased to help reduce body-tilt and improve on-road handling.
During on-road cornering, when both front and rear hydraulic cylinders are in a neutral position no fluid flows in the system and the stabilizer bars work conventionally to help reduce body lean. 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. When the GX 460 encounters an uneven surface, one compressed cylinder causes fluid to flow to the other cylinder, helping the vehicle to keep all four wheels on the ground. That action increases wheel travel and articulation and helps to equalize wheel loading.
The GX 460, like all Lexus models, is equipped with an array of dynamic safety systems. Vehicle Stability Control (VSC) helps keep the GX 460 going on its intended course by detecting front- and rear-wheel slip during cornering and attempting to control either condition with a combination of torque intervention and individual wheel braking. Electronic Brake-force Distribution (EBD) utilizes the anti-lock brake system (ABS) and distributes proper brake force between the front and rear wheels according to driving conditions and wheel-load.
Brake Assist (BA) is designed to determine if the driver is attempting emergency braking, and if the driver has not stepped firmly enough on the brake pedal to engage ABS, the system supplements the applied braking power.
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 five low-speed settings. This allows the driver to maintain focus while steering over very rough ground or steep grades, without having to also modulate the throttle and brake pedals. Crawl Control also actuates the front and rear “virtual” locking differentials to help reduce tire slippage and optimize chassis behavior.
Without canceling Crawl Control, the driver can reduce vehicle speed by braking or adjusting 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.
Downhill Assist Control (DAC) is designed to augment the low-speed descending ability of the transmission’s low range by helping to hold the vehicle to a target speed with no intervention from the driver. Active traction control (A-TRAC) provides the traction benefits of having locked front and rear differentials, but with lower weight. The system can apply the brake to a slipping wheel, while transferring torque to the wheels with better traction.
A steering angle indicator in the gauge panel shows the driver at a glance which direction the front wheels are pointing – useful for situations where this can be difficult to discern, such as driving off-road or when parking.
The GX 460 features standard Smart Stop Technology as an additional measure of consumer confidence. The braking system enhancement automatically reduces engine power when the brake pedal and the accelerator pedal are applied simultaneously under certain driving conditions.
Available on the Premium model, the optional Pre-Collision System (PCS) with Driver Attention Monitor Package can help reduce collision damage. The package includes Dynamic Radar Cruise Control, which uses millimeter-wave radar to measure and help maintain a pre-set distance from a vehicle traveling ahead.
The Driver Attention Monitor uses a camera to monitor the orientation of the driver’s face. If the driver is not facing forward when an obstacle is detected ahead, it alerts the driver, first with a warning chime and a warning display. If the driver doesn’t respond as the car gets closer to the obstacle, PCS will warn the driver by gently applying the brakes. To help assist the driver in maneuvering around the obstacle, the system reprograms the steering ratio, amplifying the intensity and quickness of the steering response. At the same time, PCS automatically retracts the front seatbelts and prepares the brake system to respond with full force when activated by the driver in anticipation of a possible impact.
The Pre-Collision System Driver Attention Monitor Package also includes Lane Departure Alert (LDA) and Intelligent High Beam headlamps. LDA helps alert the driver of a perceived unintentional lane departure by sounding a warning buzzer and displaying an alert. It does not steer the vehicle independently and it requires the driver to maintain active steering control. Intelligent High Beam headlamps that automatically switch the high beams to low beams when encountering oncoming vehicles or approaching vehicles from the rear.
The versatile passenger-side second row seat slides 4.1 inches fore/aft to maximize passenger and cargo carrying ability. The foldable and reclining second row seats also feature a 60/40 walk-in function to access the standard power fold-flat third row seats. The rear door window has a flip-up glass panel for added convenience.
Equipped for family multimedia entertainment, the GX 460 comes standard with a Lexus Premium nine-speaker audio system with iPod®/USB connectivity, Bluetooth® hands free phone capability and music streaming, and an integrated SirusXM Satellite Radio receiver (complimentary 90-day trial subscription included). When connected to the USB port, the iPod can be controlled through the audio system or steering wheel controls, while information such as names for the artist, track and album is displayed on the headunit or optional navigation screen.
A rear back-up camera is standard and provides the driver a view of what its lens can detect behind the vehicle when engaged in reverse gear, projecting the image on the standard 4.2-inch multi-information display, or the optional navigation system’s LCD display.
The hard disc drive (HDD) navigation system is a standalone option and features Voice Command casual language-based voice recognition system and Bluetooth phonebook download to enhance owner convenience. The available 17-speaker Mark Levinson® Premium Audio system is the platinum standard for OEM mobile audio. The available Rear Seat Entertainment (RSE) system includes two LCD screens, one in each of the front seat backrests. Three-zone automatic climate control for enhanced third-row passenger comfort is also available as a standalone option.
Available on the Premium model, with the optional Pre-Collision System (PCS) with Driver Attention Monitor Package, the Wide-view Front and Side Camera is designed to enhance visibility in tight settings, such as parking garages, and to help the driver’s view around corners when pulling out of parking spaces into traffic, and stopped at intersections and T-junctions. The available Intuitive Parking Assist helps the driver detect obstacles at the front, rear or corners of the vehicle and helps guide the GX into street or garage parking spaces.
