 2006 2007 Lexus RX is too dedicated to the plush-riding Lexus ideal-even when rolling on its optional eighteen-inch wheels-to mount a serious challenge to the X5. Likewise, the steering is fine for straight ahead, but there's no buildup of effort as you turn the wheel. We were impressed, however, with the RX330's tightened turning circle. 2006 2007 RX 330 delivers everything the original did and adds a good deal more luxury. Despite a herd of imitators, we predict its popularity will be undiminished. For 2006 2007, Lexus releases the second generation RX 330, which is available in 2WD or 4WD configurations. Roomier than the model it replaces, the RX 330 features a new 3.3L V6 engine producing 230 horsepower. A new five-speed automatic transmission has also been added to the powertrain.
2006 2007 Lexus RX is larger, stiffer, and heavier. Good thing the V-6 engine has been enlarged from 3.0 liters to 3.3 and has been imbued with an additional 10 horsepower and 20 pound-feet of torque. That's enough to enable both the front-wheel-drive and the all-wheel-drive RX330 to snap off sub-eight-second 0-to-60-mph times, which, Lexus says, makes the RX330 quicker than the Acura MDX, the BMW X5 3.0i, the Mercedes-Benz ML320, and the Volvo XC90, its major competitors. It also returns a commendable 18 mpg in the city. Besides the larger engine and the five-speed automatic, another powertrain upgrade is the redesigned (optional) all-wheel-drive system, which has a center differential that splits torque 50/50 front to rear and then uses the Vehicle Skid Control sensors to send torque across an axle in the case of wheelspin.
