The Flex has defied classification since its introduction. The model combines minivan-like versatility with station wagon looks, an SUV profile, and car-like driving dynamics. The exceptionally open cabin seats seven adults comfortably and its second-row seats are about the most spacious you'll find. Meanwhile, dual rear-seat sunroofs let in lots of light. The standard 3.5-liter V6, mated to a six-speed automatic transmission, isn't the most refined powertrain. However, it pulls well and gets 17 mpg overall. The optional EcoBoost V6 delivers effortless power and the same fuel economy. The ride is comfortable and quiet. The Flex also has very good fit and finish. Among our gripes; the driver's footwell is a little cramped from the left, the cockpit feels narrow, and the MyFord Touch control interface is both complicated and distracting.
