Might not be an applicable comparison because they are two different cars from different manufacturers.
The potential for fuel savings is higher in the CX-5 considering it can run in FWD mode on roads where you don't need AWD. If I'm not mistaken, the reason Mazda stayed with a FWD based AWD system is for fuel economy reasons. Nah, it's just economy reasons, so they wouldn't have to re-design their cars.Not saying it is only fuel efficient when in FWD mode, because Mazda even said that when driving in snow, it will run in AWD mode because it is more efficient than running in FWD mode. Whether the fuel savings are significant enough to be noticed in 1 fill-up, I don't know, probably not. But it might be significant enough in the long run. The Jeep cost around 1mpg or less was the consensus, driving the front tires 52% and the rear 48%, spinning both drive-shafts. Highway
Also, I think the AWD system in the Mitsubishi Evo was the best AWD system under $45k.
