450h AWD in the Snow

getting off topic ,,, I are grew up with a diesel car. That thing had too much low end torque and driving off in 2nd was never a problem and with clutch wear, I could even start off in 3rd.
The Auto trans just does not give you the needed options.
My wife' GS400 usually starts of in 2nd [auto tran] ... once in a while after a good warm up and on an upward incline, it does decide to start off in the 1st.

Simply real AWD has all 4 wheels independently vectored. Rear axle should have two motors for that. Acura MDX hybrid interestingly has two motors. Toyota/Lexus is very conservative implementing evolving technology. Nowadays most everything is done by software(firmware) control using fuzzy logic, AI logic rather than hardware. We have to keep up with technology. One reason why Toyota/Lexus is reliable(?)
I did not have looked at Audi, Porsche, BMW hybrid AWD. Few miles from highway to my cabin has rough road. One thing I feel is RXh rear end is too light. Feels like rear wheels are trying to float in deep snow.
Really it comes down to driver should understand fully what kind of vehicle (s)he drives tackling all terrains. Many are vehicle operators vs. drivers. Everything in life has a limit.

I am familiar with the various designs, but have only owned Ford 150, Dodge Ram, and the AWD RXh while in my present home in rural Michigan. The closest road from my driveway leading away from our lake home is very difficult to ascend if/when it is polished snow (or worse - ice); and the RXh is much better at it in AWD than the Ram is in 4X4.
I'd entertain a discussion as to why the AWD RX’s individual-wheel control is superior to transfer-case-gear-locked 4WD from an engineering/Safety/driving perspective; but it sounded like you had something to share with the group about the RXh’s snow capability (or lack thereof?).
In my experience - noteably the slippery grade at my residence - the combination of electric control and individual wheel position brake-controlled traction in my RX is superior the Dodge’s 4x4 ON THE STREET.
Now, if I wanted OFF-road prowess, I’d ask to borrow my buddy’s 4 x 4 Pinzgauer.

Nate:
What is the weight distribution front to back on your Dodge Ram?
My son's friend gave us a visit in his raptor on a nice dry day. Our driveway is not very steep but it is curved and the trick is to keep the vehicle moving. Raptor left skid marks at every place the young driver decided to stop.
4x4 means the engine gives power to 4 wheels, but traction is another story.

4x4 implies there is no center differential, which means front and rear wheels will be fighting opposite forces as the vehicle drives on a curve.
The more locked the system is, the more rubber it will leave behind, as something has to give to compensate for different rotational speed.
These typically do not want to turn and are good for moving in a a straight line.

Even at 50/50 weight distribution, it still takes more than double amount of traction in the back to get the front wheels to drive over snow.
