Improving the performance

The 2011 Lexus RX 350 doesn't disappoint when it comes to a smooth quiet ride. You would expect Lexus vehicles to be exceptionally quiet, and the RX is no exception. The suspension is compliant and the added insulation will keep Denver driver’s and occupants well insulated from the noisy outside world.
The 3.5-liter V-6 is also notably quiet, but more than powerful enough to accelerate this crossover with ease. The suspension does feel soft, but for those Denver driving enthusiasts wanting a more sporty driving experience, the Lexus RX 350 can be ordered with the firmly tuned Sport package.
The RX 350 responds well to throttle out on the road. The six-speed automatic uses a lower first-gear ratio than the typical 5-speed, and it gets the RX quickly up to highway speeds and works well going up I-70 into the mountains.
The RX 350 is built more for passenger comfort and not for spirited driving. The double-wishbone independent rear suspension has a lot to do with that. But it still has good road manners when taking tight corners fast.
