Where does a wagon end and an SUV begin? 58 and 72 inches, if you ask Ford. The latter is the height of the company's super-selling Explorer while the former measures the once-popular Taurus, and standing between them is Ford's latest five-door family hauler. Its name is Freestyle, its roofline stands between them at 68 inches off the ground, and Ford has declined to put a label on it.See, automakers are well aware that people are tiring of SUV drawbacks and are now trying to sneak back into the station wagon category without anyone noticing. Keeping them tall and offering all-wheel-drive seems to do the trick, so the Freestyle conforms. Yet most of the wagon cues are present as well: low ground clearance, unibody construction, independent suspension, overhead cam engine, front-wheel-drive basis. Could this be the best of both worlds?Ford sure borrowed a lot from the old world, snatching a platform from its most valuable European subsidiary (Volvo) to use for the Freestyle's blueprints. Aside from safety, Volvo knows a thing or two about station wagons, and thinking of the Freestyle as an extended Volvo V70 with a Ford engine isn't too far off.
