2010 Lexus RX350: All-new, with more technology but less complexity.

As vehicles become more complex, driving becomes more like operating a computer. Yet the new 2010 Lexus RX 350 and RX 450h seems uncommonly easy to operate. And they are brimming with new technology. If the RX were a computer, and in more ways than ever, it is, it would have a plug-and-play operating system and an inviting, engaging user interface.

When driven back-to-back against the previous model, it's clear the new 2010 RX offers more than cosmetic improvements. Mechanical improvements for the all-new Lexus RX include an independent rear suspension, a 10-airbag safety system, a six-speed sequential transmission, and an improved all-wheel-drive system. Upgraded accommodations include better seats, integrated satellite radio, acoustic glass, automatic high beam control, and a heads-up display among other things. Many of the improvements are due to more and better computer logic for integrated control of driving systems such as the transmission, all-wheel-drive, navigation, steering and brakes.Perhaps the key interior upgrade is the introduction of a mouse-like controller which Lexus calls Remote touch. It's used instead of a touch screen to operate climate, audio and the navigation system.
