Thousands of stories have been written about the 2011 Chevrolet Volt, but if you read many of them with a keen eye, you realize the author doesn't quite have all the facts about this series hybrid car (with plug-in capability) — and often inaccurately called an electric car. It's no wonder given that information has been released in fits and starts, and then revised, and revised again.

Fortunately, John O'Dell, our resident Green Car Advisor, has place together an A-to-Z guide to the Volt that provides answers to nagging questions.

For instance, writes O'Dell, "the engine-generator automatically kicks in when the battery charge is 70 percent depleted, proving the juice the electric drive system needs to keep operating.

"[But] contrary to what you might have heard elsewhere, the Volt's engine-generator doesn't recharge the battery pack. It can trickle a little excess juice into the pack from time to time, but its primary job is to keep the electric motor fed."
