2012 Lexus GX 460 Luxury SUV Combines Capability and Comfort

·         GX 460 Has Earned An EPA-Estimated 17 MPG Combined With 301-hp V8
·         Fold-Flat Third Row Provides Versatility for Passengers or Cargo
·         Body-on-Frame Construction Helps Provide Durability for On and Off-Road Adventures


The luxurious Lexus GX 460 luxury utility vehicle features a quiet cabin and a long list of standard features and options that make it a versatile choice for city and off-road driving. With its seven-passenger, three-row configuration and body-on frame construction, the GX 460 combines “right sized” mid-size packaging with family-friendly comfort and premium craftsmanship.    

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.
 
Engine/Transmission/Drivetrain/Performance
The GX 460 takes its model designation from its 4.6-liter V8 engine that produces 301 horsepower at 5,500 rpm and 329 lb.-ft. of peak torque at 3,500 rpm.  The 32-valve DOHC engine features aluminum alloy cylinder heads and block with dual Variable Valve Timing with Intelligence (VVT-i), which controls valve timing and overlap on both the intake and exhaust camshafts to optimize power, fuel efficiency and emissions.

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.  

Chassis/Body/Suspension/Tires/Brakes
The GX 460 is one of the few premium brand luxury utility vehicles that can deliver genuine trail driving capability.  Combining that capability with Lexus luxury and on-road performance makes it even more exceptional.  Lexus studied vehicle usage of current owners and found that many use their GX for family hauling during the week and vacations and camping trips on weekends.  They often tow a boat or watercraft and sometimes drive to areas with unpaved and rugged trails.

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 available Adaptive Variable Suspension (AVS) with three modes: Normal, Sport and Comfort, and independent front suspension delivers a smooth on-road ride without compromising rugged off-road capabilities.  The GX 460 rides on standard 18-inch alloy wheels with 265/60 R18 tires.

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.
 
Crawl Control and Downhill Assist Control
In addition to KDSS, the GX 460 offers optional Crawl Control, a technology that helps make driving off-road easier. The Crawl Control feature automatically modulates the throttle and brake, allowing the driver to concentrate on steering.  Crawl Control is also useful to help navigate the vehicle through sand, mud or snow.

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.
 
Safety/Security Features
The Supplemental Restraint System (SRS) includes standard 10 airbags: dual front airbags; front seat-mounted side airbags; driver and front passenger knee airbags; second-row seat-mounted side airbags, and roll-sensing side curtain airbags covering all three rows.  The front airbags are designed to inflate according to collision severity.  The roll-sensing side curtain airbags are designed to deploy when a severe tilt angle, roll or lateral G-force is detected.    

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.  

Active front headrests move up and forward almost instantly in the event of certain types of rear-end collisions when the force of the occupant's body is applied to the seat back. The available Adaptive Front-lighting System (AFS) illuminates a turn or curve as the driver steers into it and includes High Intensity Discharge (HID) headlights.  Standard headlamp cleaners on the Premium model help ensure optimal headlight performance in almost all weather conditions.

Exterior Design
Lexus designed the GX 460 to combine function and elegance, with unmistakable brand identity rooted in the L-finesse design language.  The overall effect conveys the vehicle’s full-range capability and luxury credentials.  A key goal of the designers was to have the vehicle create the impression of being sculpted from a single block of metal.

The distinctive grille features three horizontal bars and, upon closer inspection, intricate detail and texture that conveys renowned Lexus attention to detail.  Distinctive character lines on the hood and a chrome surround frame the grille.  The front bumper features standard integrated fog lamps.

Functional design elements include low-profile roof rails and an acoustic insulation windshield that help reduce wind noise.  Tasteful luxury touches abound, including green-tint UV protection front glass, privacy glass on rear windows, and running board courtesy lamps.
 
Interior Design
The GX 460 provides the luxury appointments and workmanship of a Lexus sedan. The GX 460 uses one-touch power windows with motors that reduce speed near the closure point to minimize the sound of the window closing.

The instrument panel is designed to appear as if formed from a single metal bar and is arranged to place all vital controls within easy reach.  Optitron® instrument gauges are a traditional and functional Lexus design element.  Leather-trimmed seat facings, headrests, armrests, door trim, shift knob and steering wheel also add to the Lexus touch.  Wood trim, instrument panel stitching and soft-touch surfaces enhance the luxury feel.
