2010 Lexus GX 460 review:

2010 Lexus GX 460

Given the character of the GX 460, we were surprised to see a Sport mode on the six-speed transmission. In this mode, the SUV might hit Lexus' reported 7.8 seconds to 60 mph, as it lowers the shift points. But it didn't downshift aggressively in turns. Given this vehicle's poor fuel economy, using its Sport mode will just burn more gas without delivering much benefit.

Ignoring the various sport settings, the GX 460 proved easy to drive in most circumstances. The big engine gave it enough power for passing maneuvers and its turning radius was reasonable for such a big vehicle. A backup camera and side mirrors that automatically dip down when the car is put in reverse helped us while parking. The image from the backup camera is crisp, but it doesn't show any distance or trajectory lines.

Lexus also offers adaptive cruise control, lane-departure warning, and side and frontview cameras, although these were not included on our test vehicle.

Stellar sound
In one way, the GX 460 really stood out: its stereo had excellent audio quality. With the navigation system comes a Mark Levinson audio system using 17 speakers and a 330-watt amplifier. This system goes deep in even compressed audio tracks, bringing every tone to the surface. We are always pleased when an audio system surprises us with sounds in a track we hadn't heard before.

However, the Mark Levinson system not only finds these sounds, but also makes them real. It recreated tambourines and other percussion instruments, placing them clearly in the cabin. In one track that fades out to the sound of a car driving away, it seemed like a Chevy had just driven through the GX 460's cabin. The sound is also well-balanced, keeping highs from getting too shrill or bass from rattling door panels, yet still producing a chest-felt thump.

Browsing an iPod library causes any album at the top of the list to start playing immediately.

Unlike most other automakers with hard-drive-based navigation systems, Lexus doesn't let you rip CDs to the car. That leaves iPod integration, Bluetooth streaming audio, satellite radio, and a six-disc CD changer as audio sources. For iPod integration, we had the same complaint as in the Toyota Sienna: land on any album or artist while viewing the library with the touch screen, and it starts playing immediately, ruling out any idle music browsing.

Another thing we found annoying is that the navigation system would not mute or pause the stereo when it issued route guidance voice prompts. With such a good audio system, we frequently had it turned up loud, drowning out the next turn directions.

Lexus uses its latest Bluetooth phone system with the GX 460. Not only does it download a phone's contact list, but it also makes the names available through the voice-command system.

In sum
The big 2010 Lexus GX 460 has some interesting design quirks, such as a side-opening rear door. Stylistically, its side graphic, the window, and pillar arrangement, is nicely sculpted, but the whole vehicle hardly cuts a unique figure on the road. The cabin tech interface looks good, but iPod integration is difficult to use.

Although Lexus fitted it with a new engine, variable-valve timing is nothing new, and the six-speed automatic transmission is pretty standard these days. The only things giving the GX 460 a bump in performance are its off-road systems, which could be useful if an owner were to take this $60k vehicle into the back woods.

The GX 460 really stands out for its cabin tech. Although we would like to see richer maps, the ability to pick destinations from a PC then download them to the car is very cool. The stereo sources are pretty standard, but the audio quality from the Mark Levinson sound system is superior to most other factory offerings. The availability of driver-aid systems such as adaptive cruise control, lane-departure warning, and cameras all around boost its tech credentials.
