Lexus has revealed the second-generation of its GX midsized luxury SUV, the GX 460, ahead of its official debut next week at the LA Auto Show. The same size as the model it replaces, the new GX 460 is still an old-fashioned, body-on-frame design that shares a platform with the redesigned Toyota 4Runner. Both are traditionally capable off-roaders. But it promises more refinement, through technology and conveniences. For example, a power-folding third-row seat folds flat into the floor, rather than up against the sides as the old one did. And that is just the beginning.The name change also represents moving to a new 4.6-liter V8, which makes 301 hp, up from 263. The standard transmission is a new six-speed automatic–upgraded from last year’s five-speed. EPA fuel economy estimates are 15 mpg city and 20 highway, for a combined 17 mpg; the last GX returned 15 mpg combined.
A host of new high-tech features provide protective systems for everything from off-road driving to on-road crash performance.
Previously optional, the new Kinetic Dynamic Suspension System (KDSS) is now standard. It hydraulically controls the anti-roll bars for reduced body lean in corners, and disengages the bars for greater off-road articulation. The vehicle also has downhill assist control to automatically limit descent speeds on steep slippery grades off-road. The Crawl Control, trickled down from the Land Cruiser, is a feature that automatically controls the throttle to maintain a set speed on slow off-road ascents. Crawl Control engages automatically when low-range is selected and the crawl speed can be adjusted manually. Hill start assist keeps the vehicle from rolling back when starting on an uphill.
