What's New for 2007: The Lexus RX 330 becomes the RX 350, thanks to a larger, more powerful engine. Beyond the engine, the standard equipment hasn't changed. Further, the hybrid-powered RX 400h is offered with front-wheel drive as well as all-wheel drive. The RX 400h now comes standard with the same equipment as the RX 350, except its hybrid gas-electric powertrain. Previously included features such and power tilt steering, moonroof and leather seating are optional.

The 2007 Lexus RX 350 is available with a choice of front-wheel drive ($37,400) or permanent all-wheel drive ($38,800). Both models are powered by new 3.5-liter dual-overhead-cam V6 engine that delivers 270 horsepower through a five-speed automatic transmission.

The RX 400h also offers a choice of front drive ($41,180) and all-wheel drive ($42,580) with Lexus Hybrid Drive technology.

Standard features on all models includes cloth upholstery automatic climate control, a 132-watt AM/FM/cassette stereo with eight-speakers and an in-dash, six-CD changer, cruise control, privacy glass, automatic headlamps, 10-way power adjustment for both front seats, 17-inch aluminum wheels and leather trim for the steering wheel and shift knob.

Options for both the RX 350 and RX 400h: The Premium Package ($1,245) includes leather upholstery, power tilt/telescope steering wheel, a roof rack and power moonroof. The Premium Plus Package ($2,060) adds high-intensity discharge headlamps that turn in the direction of travel and entry lights that illuminate the ground below the doors.

The navigation system ($2,650) has been upgraded for 2007 with Bluetooth and voice command capability and improved graphics, and it includes a rear-view camera that projects an image of what's behind whenever reverse is engaged. The nav system with Mark Levinson audio ($6,190 for RX 350, $4,130 for RX 400h) adds 240 watts, more speakers with a subwoofer and high-tech digital sound processing. Mark Levinson audio is available as a stand-alone option on the RX 400h ($980).

The giant multi-panel sunroof ($2,840) comes packaged with other features. A heated-seat package ($665) adds rain-sensing wipers and headlight washers. The Tow Prep ($160) package adds a transmission cooler, heavy-duty alternator and larger radiator. Other options include a rear-seat DVD entertainment system ($1,740), laser-managed Dynamic Cruise Control ($600), the HID headlamps ($815), and heated front seats ($540). XM Satellite Radio is offered as a dealer-installed option.

The Performance Package ($4,055) is the one option group offered only on the RX 350. It includes all of the items in the Premium Package, plus 18-inch graphite-colored aluminum alloy wheels with wider speed-rated tires, height-adjustable air suspension, sequential-shifting transmission, rain-sensing wipers and a power rear liftgate.

Safety features that come standard include the mandated front airbags, plus a smaller airbag to protect the driver's knees. Front passengers get side-impact airbags for torso protection, while the curtain-style head protection airbags span both rows and deploy to offer head protection if the vehicle senses the possibility of a rollover. All RXs feature advanced ABS, traction and stability electronics.
