Ford Edge with HySeries Drive is world's first drivable fuel cell hybrid electric vehicle with plug-in capability. HySeries Drive technology is able to operate using a fuel cell, small gasoline or diesel engine connected to an electric generator to make electricity . The HySeries combines an onboard hydrogen fuel cell generator with lithium ion batteries to deliver more than 41 mpg, while some drivers will see fuel economy well over 80 mpg. The HySeries Drive name is derived from the powertrain's structure: a hydrogen fuel-cell-powered series hybrid drivetrain. This highly innovative approach reduces the size, weight, cost and complexity of a conventional fuel cell system by more than 50 percent. It also promises to more than double the lifetime of the fuel cell stack. The vehicle is built on a flexible powertrain architecture that will enable ford to use new fuel and propulsion technologies as they develop, without redesigning the vehicle. The plug-in hybrid is...
