Ford's diesel-electric hybrid Reflex Concept features solar panelling

Reflex's energy is stored in a new-generation lithium-ion battery pack, using the same technology found in cell phones. Ford was the first manufacturer to produce an electric vehicle using this type of battery system when it introduced the electric Ford Ka research vehicle in 2000. Also contributing to Reflex's power and performance are unique headlamps and taillamps that integrate solar panels. The Ford-patented battery-charging lighting system improves fuel economy by using the sun's power to charge the on-board batteries, while capturing and reusing the daylight at night.

Reflex also uses ground rubber from scrap athletic shoes, called Nike Grind, as insulation to reduce noise and vibration in the car's interior.
