The Saturn Vue Green Line is not a full hybrid, which means it cannot operate on the electric assist motors alone. That's not ideal, but the compromise equates to a lower price tag for the technology. The Saturn Vue's hybrid powertrain isn't the most refined – the engine kicks on and off with a shudder, for example – but is adequate for the commuting most people do. If you need more power, the Vue Green Line can deliver but not with extra reserves. I like the traditional transmission mated to this hybrid because when accelerating the Vue doesn't suffer the long, protracted drone of a typical hybrid with a CVT.
