Ford does a good job creating efficient powertrains, and thier idea that 4WD is better than RWD in large vehicles (such as the Taurus, Explorer, Edge, and Flex) makes a lot of sence, however, I'm pretty sure using FWD over RWD in these large vehicles is simply robbing them of thier best performance figures, and towing capacities (at least for the suv's). Ford should get rid of the FWD option in these vehicles, and replace it with a RWD option, for various reasons. For example, making the Explorer, and Flex RWD will help increase thier towing capacity, and help them to handle better, since, through proper gearing, the torque could be vectored around a turn. As for the Edge, and Taurus, it would greatly help thier overall performance figures, by making them weigh less (than a 4WD), and handle better for reasons stated before. Ford already has plenty of technological goodies to aid the 4WD systems in these vehicles, so why not adapt them to an efficient, and cost effective RWD system?
