I tried the new Rx, albeit a non hybrid version. Here some of my impressions:
-Exterior, design wise, it starts to grow on me.. I still prefer the 2nd gen RX though. Some clever details; I like the new mirrors and their placement, I like the hidden rear wiper, although wonder how to change it, I like the keyless entry
-Trunk: wider loading areas, but no more little compartments underneath, no easy way of keeping grocery bags or similar right up. Hatch opens a bit higher than previous, but still to low for me (6.3), easy handle to flatten rear seats.
-back seats: noticeably more legroom. 2 dvd screens seem a bit to much to me, I prefer 1 roof mounted screen.
-Drivers seat: even more comfortable than 2nd gen RX, cooled seats are a nice touch, dash is nice, navi screen is better placed, the control thing is easy to use, much better than I thought, one large centre armrest with deep bin underneath. I did pinch my fingers badly while moving the arm rest forward, so watch out! Shift stick is hiding heating controls when in P, heating controls are a bit random, no logic there, interior color schemes are as before, and personally I think they are very ugly.. The only combinations acceptable for me are al black with darkwood or what I currently have grey with black wood, if only Lexus would offer a choice of wood replacements, like brushed metal or full leather or piano finish or just a more modern type of wood...
Nav is much better, voice control is usable now.
Drive: nice, a little bit more sportier than before, a bit better in the corners, a bit faster, less noise.
All in all small improvements, nothing dramatic.
O yes, the new red is nice!
