GM hopes people will stop asking who killed the electric car. This week the company unveiled an ambitious test-drive program, Project Driveway, to highlight its work with fuel cell technology. “Project Driveway” is lending 100 New York-area families a Chevrolet Equinox outfitted with a fuel cell propulsion system. For the next three months, the drivers will have one place – a new hydrogen refueling station in Westchester – to fill up. But the 350-mile range means there will soon be a bunch of these SUVs commuting to Manhattan. There have to be significantly more stations in the metropolitan area when Chevrolet brings the fuel cell Equinox to market in two years. Unlike hybrids, which typically combine gas-powered engines with fuel cells or electric battery power, the Equinox relies on just one system. It’s powered solely by hydrogen and emits only water.

Some engineers have claimed that the water is clean enough to drink. But try not to hold your cup up to the tailpipe of a Chevy Equinox during the next 90 days unless you’re really certain it’s powered by fuel cells.
