Developed in cooperation with Mitsubishi, the Smart ForFour adds a second, larger line for the trendy automaker, as it prepares to expand into new markets. On sale in Europe this fall, the ForFour carries the two-tone appearance and wafer-thin overhangs that help distinguish the brand's diminutive vehicles. Despite the name, there will also be a five-passenger model offered. As with the smart city-coupe, customers can choose between a plastic roof, a panorama glass roof, and an electric glass sunroof for the smart ForFour. A Brazil-built ForFour variant will be offered in the United States, likely with a more aggressive exterior, increased power, and possibly all-wheel drive.
