Saturn Aura Green Line – 2007 Preview: The Saturn Aura Green Line joins a product lineup that eschews Saturn’s traditional dent-resistant body panels in favor of European styling and sophistication. With the addition of the Green Line, the Aura expands to three models and is also the first hybrid sedan from GM (the rest have been trucks or SUVs). The Aura Green Line will be out-powered by the base model, but Saturn hopes its improved fuel economy and hybrid cachet will outweigh that shortcoming. The price difference is also offset with a higher level of content, splitting the difference between the XE and the XL. Most important is price, as it will be one of the largest and least expensive hybrid sedans on the market.
