The 2007 Saturn VUE SUV has updated its lineup with the aptly named Green Line Hybrid. This new model uses a 2.4 L, 170 hp Ecotec inline-4 engine and seats 5. It uses gasoline when the car moves, then switches primarily to electric power when the driver brakes. Saturn has given the new hybrid a similar appearance to the other trims. In addition, the Green Line has improved on the traditional VUE's fuel consumption by almost 20% and lets you know with a gauge that flashes the word Eco when fuel economy exceeds the EPA average. The other gasoline-powered trims remain relatively unchanged. Gas mileage still runs from around 20 mpg in the city to 28 mpg on the highway. Saturn has modernized the interior and added standard remote keyless entry to all trims. Overall, reviewers appreciate the almost seamless transition from the gas-powered VUE to the environment friendly Green Line. Solid handling on all trims makes it hard to tell them apart. The VUE's evolution shows how Saturn has placed a premium on function while slowly developing the form. For all the hype about the new hybrid, the new Saturn VUE chooses not to toot its own horn until you step in and drive.
