As predicted, the redesign is evolutionary. The car has much softer lines and curves than its predecessor, most evident by the toned down fender arches. The headlights aren't swept back as much either. The car's grille has also been updated with corners that don't stretch down as far, which reflects that of the updated American Fusion and European Mondeo.
This particular Fiesta is also a European ST-Line model. This trim adds a sporty-looking interior and some exterior bits to make a normal Fiesta appear more like a high performance ST model, but with none of the mechanical parts. Expect the standard model to look a bit more tame, and the ST to be more aggressive.
Ford has yet to reveal other details, but they should come later today. We expect the Fiesta will be more efficient and more refined, and to go on sale sometime next year, probably around the same time as the EcoSport subcompact crossover.
