Replying to: stevedebi (Feb 07, 2006 3:21 pm) On cold days when the batteries are colder than their operating range they will be of dimminished use to the HSD system. As the interior of the car warms up (or if heaters are used in the battery compartment) then they will "come on line" as they reach operating temp. While this is happening you are burning gas and therefore getting less fuel efficiency in cold weather. Conversely, that same is true on hot days when the batteries are above their operating temp. They will not be able to supply peak current and therefore the gas engine will have to pick up the demand. Just as a point of observation, I think the main reason the batteries are inside the cabin with the passengers is that they perform best with the same thermal range as is comfortable for humans. There is a synergy there.

Is the RX 400h driveable on sand? I need a vehicle that can be driven off-road, expecially loose sand on beach as I go surf fishing frequently. Does the manual for this vehicle have anything to say about settings for driving on sand? Any opinions are appreaciated. Thanks.

Replying to: vpotluri (Mar 06, 2006 7:45 am) Though we tried the RX 400h on a couple of cane haul roads, Lexus engineers were quick to point out that although the RX 400h is technically an all-wheel-drive vehicle, it's not a capable off-roader. True, the mass majority that will buy this hybrid SUV won't ever take on any thing worse that a graded dirt road, or on snow. However, sand is to be avoided. With the aft electric motor being air cooled, there's a concern for excessive heat build up, which would cause the system to shut down (to protect itself), temporarily leaving its passengers stranded. If you want to go off road, the Lexus RX 400h is not for you. lolop, "Lexus RX 400h" #477, 18 Nov 2004 9:20 pm
