Yea the Edge benefits with just being a 5 seater, the Taurus X and future Flex will be Fords 3rd row seat offerings in the crossover marketplace. The thing im very concerned with is Fords future product lineup according to the rumors
Escape seats 5- 4 and 6 cylinder power (even in a futire offering, prob moving to more compact platform)
Edge seats 5- 6 cylinder power
Taurus X seats 7- same 6 cylinder power as Edge- very safe- Flex could spell disaster to its future
Flex seats 7 or 8- same power as Edge and Taurus X, very large cargo, but overall very similar in conceptual design to Taurus X
Explorer seats 5-7- 6 and 8 cylinder power- rumored to be moving to unibody crossover platform in next generation, if this can really stand out and maybe offered only in 8 cylinder power, it may be able to set itself apart from the Flex.
This is my idea of what Ford should do to stop confusion, bring the all new Euro Ford Kuga over and badge it as the Escape with only a 4 cylinder to compete with Rav4 and CRV. The Edge would stay the same, I think in the next intro of a new Taurus, i would drop the Taurus X in an attempt to lose confusion between it and the Flex. Keep the Flex the way it is as a minivan alternitive, and finally make the Explorer the unibody like rumored and make it high profile with a sole V8 option.- This would round off all Ford SUVS and crossovers besides the Expedition and give Ford a well balanced and competitive lineup.
