I'm a big guy 6' 240 lbs. in our new 2015 RXh I drop the driver set down all the way and I feel comfortable.

I rode shotgun yesterday when my wife was driving and I was surprised that the passenger seat height is much taller than drivers seat when set at the lowest position. It's actually too high for me even at the lowest setting. Is it just me?

 

Responding to my own posting.

I dropped of our RX450h at the dealer today to get credit card keys programmed and look at the intermittent parking sensor. They gave me a RX350 loaner. The passenger seat on it also will not go as low as the driver seat. I guess that it's a *feature*

 

I think it's been that way for a while. My '02 RX seemed to have that problem. I had a couple of passengers that were 6' or just over 6' who mentioned their head was right at the headliner.
I have no clue as to the reason.
