Post by Ray OPost by borisHi,
Is RX400h AWD system is capable as one in RX350: for winter driving?
RX400h doesn't seem to have limited-slip differential. Also, what is
*real* gas mileage (for RX400h)?
Thanks in advance for any info.
Boris
Yes, as long as you do not drive in extremely deep snow.

Ray, what disadvantage would the 400h have versus the 350 in deep
snow? There is only .28 in difference in ground clearance, and VDIM
with TRAC act in essence like a limited-slip diff by transferring
power to the wheels with more traction. Although the 400h rear
electric motor does not put as much total power to the rear wheels as
a 350 can, in deep snow at slow speed the front wheels probably have
the most traction anyway.
*********
In re-reading my response, it was not worded clearly. As far as I know, the
400h does not have a disadvantage versus the 350 in deep snow, but neither
is very good in deep snow or in rough off-road conditions because of the
relatively low ground clearance and car-type suspension. The same could be
said for most, if not all, car-based crossover SUV's. If you intend to
drive in very deep snow or in rough off-road conditions, a vehicle like the
GX or LX would perform better, with the payoff being less fuel efficiency.
