Built off a similar chassis as the Red Line Ion, the Cobalt SS Supercharged was developed alongside all the other serious GM Performance Division contenders at Germany's famed Nurburgring road course, GM's secretive Milford Proving Grounds and other testing facilities around the world. Like all GM Performance Division vehicles, it has world-class 60-0 mph braking distances thanks to oversized rotors and calipers. This car can go, turn and stop with the best sport compact vehicles in the world.
