The luxurious Lexus GX 460 luxury utility vehicle carries over into 2013 with its 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 GX 460 has EPA-estimated fuel economy ratings of 17 mpg combined, 15 mpg city and 20 mpg highway.
The GX 460 is one of the few premium 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. 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 front/rear under most driving conditions and changes the ratio as needed based on wheel slip.
The ability to change to a 30:70 front/rear 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 front/rear 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.
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 sway 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- lean 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.
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. The driver can reduce vehicle speed by braking or adjusting the crawling speed with a selector switch.
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 following distance from a vehicle traveling ahead.
The Driver Attention Monitor uses a camera to monitor the orientation of the driver's face. If it determines that 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 changes 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 increased braking force when activated by the driver in anticipation of a possible impact.
The Pre-Collision System Package also includes Lane Departure Alert (LDA) and Intelligent High Beam headlamps. LDA uses certain lane markings to help alert the driver of a perceived unintentional lane departure by sounding a warning buzzer and displaying an alert. Intelligent High Beam headlamps automatically switch the high beams to low beams when encountering oncoming vehicles or approaching vehicles from the rear.
The Lexus GX 460 also offers Lexus Enform® with Safety Connect®. Lexus Enform with Safety Connect is standard on all vehicles equipped with the optional Navigation system. The Lexus Enform and the Safety Connect response centers operate 24 hours a day, 7 days a week—every day of the year. Complimentary one-year trial subscriptions are included on all purchases of new Lexus vehicles equipped with these features.
Vehicles equipped with Lexus Enform are factory ready for subscriptions to a variety of innovative SiriusXM services including NavTraffic, NavWeather, Sports, and Stocks. SiriusXM data services offer complimentary one-year trial subscriptions and require a separate audio subscription.

301 HP in this whale? Hope they don't plan to tow anything... yea I know most that buy these typically don't tow but on occassion they will attempt a boat but with this... I would maybe suggest a Jet Ski at max! And 20 mpg
Damn thing will be lucky to pull Granny off the piss pot!

301HP V8? That's pathetic!!!
Guess what, the Expedition (and Navigator, for that matter) with the Triton V8 has more power, A LOT more torque, and also gets 20 MPG on the highway. And how long has this Expedition been out? Since like 2007? And to make things worse, the Expy is a fully size up from this disgrace of a BOF SUV.
And who the hell is going to take this thing off-road? Probably some desert-running Cartel but that's about it.

I will up you one... Try a Tahoe, with the 5.3L which its rated 21 mpg and it's been out since..... 2007

I wonder if lexus is going to try and fuse their current styling direction into their suv lineup..
It will look hilarious...

They did it on the RX. Not a new car, just a new front end.
It's hilariously bad.

For the RX, that treatment is helping it.. Made it from ridiculous ugly to hilariously bad... I guess i would rather laugh at it than throw up at it...
