Car Forum / Lexus Cars / November 2008RX400h AWD system
Hi, 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 > Hi, > [quoted text clipped - 4 lines] > > Boris Yes, as long as you do not drive in extremely 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.

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.
