Ford's completely new model, the Edge, is designed as a crossover, combining the cargo space and visibility of an SUV with the comfortable ride and fuel economy of a sedan. We got a chance to drive one through the windy roads north of San Francisco recently at a Ford model launch event. Our car was the top-of-the-line SEL version with all-wheel-drive, navigation, and a premium audio system. The Ford Edge goes on sale in November 2006.
