Saturn Aura Green Line: GM's hybrid cost cutter.

The Saturn Aura Green Line offers a compelling proposition. It costs considerably less than the competing Toyota Camry Hybrid so, even though it doesn't have the Camry Hybrid's fuel economy, the lower initial outlay should make up for the extra fuel cost. On the other hand, it costs $2,000 more than Saturn's base Aura XE, which has a 3.5-liter V6 engine and lower fuel economy.
