Ford Motor Company's long-term goals are to focus on developing fuel cells and hydrogen technology.
Ford's HySeries Drive is a battery powered hydrogen fuel cell hybrid electric car that has plug-in capabilities. "The HySeries Drive technology is able to operate using a fuel cell,
small gasoline or diesel engine connected to an electric generator to
make electricity."
Aside from Ford's concept car, the Ford Airstream Concept, Ford has also unveiled the Ford Edge with Hyseries Drive, which is equiped with a hydrogen storage tank, 336 volt lithium-ion battery pack fuel cell and 2 electric motors. The Ford Edge with Hyseries Drive is the "world’s first drivable fuel cell hybrid electric plug-in that combines
an onboard hydrogen fuel cell generator with lithium-ion batteries to
deliver more than 41 mpg with zero emissions."
As stated, the new Edge delivers a highway/city rating of 5.7L/100 km (or 41 mpg) with no emissions. For distances less than 80 km (or 50 miles) fuel consumption can be reduced to 3.0L/100 km (or 80 mpg). It can travel at speeds upto 136 km/h (or 85 mph).
The first 40 km is run on stored electricity, then the hydrogen fuel cell allows it to run for another 320 km with no emissions. The HySeries vehicles can be plugged into a normal 110-volt outlet to recharge the battery. The technology is in Ford Motor's Company's long term plans of 2020 and beyond.
