GM has drawn fire for its line of full-size and thirsty SUVs. The 2007 Aura Green Line is one of 12 hybrids the company is rolling out over the next several months to enhance its “green” image, showcase its hybrid technology, and obviously draw fuel economy-minded customers to its showrooms that otherwise wouldn’t consider a GM vehicle. Saturn’s stated goal is to offer affordable hybrid technology. At a base price under $23,000, the Aura Green Line should be among the more affordable hybrids on the market.
