From the latest Lexus magazine. I copied it here, so errors are mine.
RX drivers, take note: The arrival of the next model, the RX 350 is near. The vehicle's elegant, compact body remains the same, but it now includes a larger 3.5 liter V6 engine that boosts the SUV's horsepower to 270. RX engineers also added new noise- and vibration-reduction components such as an acoustic glass windshield and extra sound insulation, and they enhanced the optional DVD Navigation System with Lexus' Generation 5 software, which, among other features, includes crisper graphics, voice-activated destination inputs, and a "bread crumbs" tool that allows drivers to retrace their steps. Also new: an optional 9 inch screen for the Rear Seat Entertainment System (RSES), as well as Mark Levinson DVD Surround Sound Audio (also optional).
