Ford is working to provide manu-facturing flexibility in its assembly plants. A prime example is the Michigan Assembly Plant, where they are building the Focus, Focus ST, Focus Electric, C-MAX Hybrid, and C-MAX Energiâgasoline-powered, electric, hybrid, and plug-in hybrid vehiclesâall on the same production line. It is the only plant in the world that is doing so. (Photo: Sam VarnHagen/Ford).
