It's expected to deliver a 50-percent improvement in fuel economy compared to a V6 Vue. That would mean about 30 miles per gallon in combined city and highway driving.
Unlike the Vue hybrid that's currently on sale, this one will be a "full hybrid" capable of driving under all-electric power at low speeds.
GM also announced at this show that it expects to begin selling a plug-in hybrid version by 2010.
All three hybrid Vues - mild hybrid, 2 mode and plug-in, will sell together at Saturn dealerships.
