Quattroruote, the most influential italian car magazine, on january 2016 made a comparison between some 4wd systems. The Toy RAV4 hybrid was the worst, unable to move the car in a slight uphill using only the rear axle (front axle on simulated ice), because of the rear engine low torque. This means that the support given from the rear axle (35% of the whole power in best conditions, with petrol engine working and fully charged battery) is poor. Oldest RAV4, with a traditional mechanical linkage between rear and front axle, works definetly better. On the other hand, the electric system needs less space under the floor, and the consumption will be better.
