Other features include seat upholstery and door linings made from what Honda calls “Bio-Fabric,” a corn-based material that's soft to touch and offers what Honda claims to be durability and resistance to sunlight damage. Other improvements include shift-by-wire – not that great, yet -- and a newly designed instrument panel with easy-to-read green and yellow graphic “ball” that shows hydrogen consumption.
