Mercedes-Benz F-cell

Based on the last-generation Mercedes-Benz B-class, the hydrogen-powered F-cell is an electric mini-minivan fueled by compressed hydrogen. Able to whir silently for 190 miles between fill-ups, the lease-only F-cell drives surprisingly normally, more like a Nissan Leaf than the starship Enterprise. That said, unless you live in California, where hydrogen-refueling stations exist, forget it.
