The boxy Flex combines SUV-like versatility with near-carlike driving dynamics. The interior is highly functional, with room for up to seven passengers in three rows, and its shipping-container shape works well for cargo. Rear visibility is hampered by big head restraints. Handling is not particularly nimble, but the ride is comfortable and the cabin remains quiet. The base 3.5-liter V6 gets 18 mpg overall. Choosing the turbo V6 gives you quicker acceleration at a cost of just 1 mpg overall. Sync 3 has replaced the complicated and distracting MyFord Touch infotainment system.
