I guess, as is the case with Subaru, the AWD with a stick is a completely different system from the AWD with a slushbox. The former has to have a preset distribution (e.g. 55/45 or 50/50), whereas the slushomatic can have the quasi-AWD, with variable distribution. I doubt, given the demand, we will see AWD with a stick on anything new....sadly.
Funny, I am in a similar situation with a "3". The average observed consumption is about 10.5-11, mixed cycle and medium to heavy foot. More space would be nice, but based on all other reviews, neither CX5 nor the 5 are as tossable as the 3....
