Potential Future Changes RX400h

I'm just stating the obvious, but whatever is in store for the RX 330 is likely in store for the 400h. I do not know what may be in store for either, but you'll probably have an easier time researching changes in the 330.

Since the RX body style was just changed in 2004, it probably won't be for a while. Lexus still has a few other body styles to update before they circle back to the RX.

Would the new generation RX or Hybrid RX eventually become the Lexus HPX? You can see some photos in the internet on Lexus HPX. Perhaps go and type the search engine on images for "Lexus HPX". I saw the ones with grey colour, with camera side mirrors, very smart looking, but closer to a station wagon...
