I knew that GM had built real, road-ready hydrogen fuel cell vehicles. But I didnt really believe it until I saw one, and drove it.

The Chevy Equinox I piloted—one of about one hundred that GM will put on the road later this year—looked as polished and user-friendly as any new car on the lot. Its a comfy, soccer-mom/dad vehicle that seems like any other small SUV until you turn the ignition—err, I mean the key. There is no ignition.
