Ford's Kuga could be getting a little brotherFord may be preparing a Fiesta-based mini-crossover, judging by the looks of this prototype we just spotted undergoing warm weather testing. The vehicle could become a junior sibling to the slightly larger, Focus-based Kuga. That European-designed small crossover is rumored to be arriving in the U.S. next year.Clearly wearing Fiesta sheet metal, this white-and-black Ford crossover prototype has significantly more ground clearance than the production Fiesta and, we're told, could be sporting an all-wheel-drive system. Take a closer look at the roof of this car and you'll see ballast added on to simulate the taller body this vehicle would receive.Demand appears to be growing for small, all-wheel drive vehicles -- especially overseas. While Toyota's all-wheel-drive version of the Matrix hatchback hasn't proved to be a sales leader in the U.S., Mini is close to entering this category with the Countryman crossover, and Hyundai has released a teaser sketch just today of the small all-wheel-drive ix20 concept. The latter crossover concept, making its debut at the Paris Motor Show, is not likely bound for U.S. soil should it make production. The same fate could befall a Fiesta crossover.
