Saturn’s sleek new Curve concept car was designed by GM North America, developed by GM’s European Advanced Design Center in Sweden, and assembled with assistance from Italian coachbuilder Pininfarina. Styling details abound, including roof pillars that are concealed by a “floating” canopy of glass, and a front-hinged, clamshell hood. The vehicle is coated in Mission Silver, a warm color chosen for its liquid metal appearance. Sports car performance is derived from a supercharged 2.2-liter Ecotec four-cylinder engine that produces more than 200 horsepower, mated to a Getrag five-speed manual transmission.
