the Toyota Prius got all the hybrid Lexus showed that a could be powerful and luxurious the RX hybrid SUV. That launched as the RX 400h in 2005, and now a much-needed update for the 2010 year. At Lexus’ preview for the we got to drive it over mountain and spend some serious trying out the new cabin tech.

The new is called the RX 450h, as Lexus up the gas engine from 3.3-liters to a V-6. And, like the model, that engine is by a full hybrid system, electric motors that can the car. With newer technology, Lexus was able to the RX 450h’s nickel-metal hydride pack, which sits the rear seat, a little As with the old version, the gas engine and one drive the front wheels.

it up to all-wheel-drive, and a second motor/generator added to power the rear

We took a sport-trimmed on a drive over twisty roads in Northern California, and a lot of improvement. Where the steering on the RX was extremely light, even at Lexus returned the electric-power to give more resistance in the RX Coming through a tight at speed, the steering wheel much more feedback. The were singing in the turns, but the suspension kept the car reasonably

Of course, there is a trade-off in the ride didn’t feel as as with the RX 400h. Lexus the suspension pretty radically in the of the RX, taking out the strut towers in of a double-wishbone. This new suspension to a firmer ride and increases the area.

More power was when we pushed the accelerator, as rates the total system at 295 in the RX 450h, 27 more horsepower with the older model. at 245 pound-feet, is up 37 pound-feet, although peak torque comes in at higher than on the RX 400h. The gas now runs on the Atkinson cycle, a of increasing engine efficiency valve timing that is used on the Toyota Prius and the Mariner Hybrid. Lexus fitted the engine with an recirculation system that the engine warm, making it to shut down the engine frequently and let the electric motors the car.

Although the power and displacement are these other technologies the RX 450h 27 mpg for the all-wheel-drive model and 28 mpg for the about 1 mpg better than on the model.

The actual hybrid behavior very similar to the current At a stoplight, the engine would off. On the green light, our low-speed acceleration was handled by the motors until we pushed the enough for the system to kick on the gas The transition felt a little seamless than on the older which could be partly of Lexus fitting it with damping materials.

According to Lexus, the RX 450h can under electric power at up to 10 mph, for approximately two minutes.

the old car had a battery mode on its transmission, the new one away with that in of an EV mode button. This tries to keep the car running electric power, but will kick in the gas engine if needed. of these power-train features are from the high-end Lexus LS sedan.

That is true of the which now has a sport mode and selection. As the RX 450h doesn’t any fixed gears, using unique planetary gearset, mode merely lets the revs higher, and the manual has virtual shift points really only help for braking.

Along with the and suspension updates, Lexus the RX 450h a complete and welcome for the cabin electronics. One of the most features is the voice-command system, can parse sentences for keywords to commands. For example, you can say, cold, and the car will turn up the Likewise, with the Bluetooth system, you can say, Can you buzz in his office?

If you have someone named in your phone book, an office number, the system dial that number. this system works Ford Sync, in that you can say the of someone in your phone and the car will place the call. But Sync, that type of command doesn’t work music.

Along with the voice Lexus updated the controller, a square joystick on the console to an onscreen cursor. This is the time we’ve seen an cursor on the screen of a production but for anyone that uses a (isn’t that everyone?), it be a familiar sight. We like you can change the settings for the cursor, a different shape and giving haptic feedback when you the cursor over a menu but the joystick doesn’t feel solid.

Worse, it doesn’t snap into its center position you move it around, which it a cheap feeling. Another of this interface is that, you have a fixed number of on the screen, you can still move the all over the place. In a car it seems it would be better to limit movement to clickable items.

The system has the usual sources, but USB drive and iPod integration. although the navigation system is drive-based, you can’t rip music to hard drive, as you can in most with this type of There is a rear-seat DVD option puts LCDs just the headrests of the front seats.

We could hear fairly notes through the frequencies, but we get a really hard snap percussion, as we’ve heard on high-end systems.

Besides the train, the gas only Lexus RX 350 be comparably equipped to the hybrid RX 450h. The RX 350 will hit showrooms in the while the hybrid RX 450h around in the early summer.
