If Red Line is for performance, then Green Line is for fuel economy. At least that is Saturn's plan. Saturn is planning a hybrid line of its vehicles called the "Green Line." The hybrids will be 'mild' hybrids, with the majority of the fuel economy improvement attained through stopping the engine during deceleration and at stops. The first Green Line model will be the Vue Green Line, which is scheduled to go on sale in mid-2006.
