Just hours before the 2010 Chicago Auto Show opened to the public, the Hyundai Blue-WiLL hybrid concept was plugged in and ready to demonstrate the latest in automotive technology. Classified as a compact four-door, four-seat sedan, it was a test bed of new ideas including panoramic glass roof with solar panels for recharging batteries, a thermal generator which converted hot exhaust gases into electricity, drive-by-wire steering, lithium polymer batteries and touch screen controls. Blue-WiLL promised an EV driving range up to 40 miles on a charge and an economy rating up to 100 mpg. Helping to achieve those numbers was a direct injection 1.6 liter 152-hp four, a CVT and a 100kw electric motor. The futuristic exterior styling was matched by a flowing interior with adjustable Transparent Organic Light Emitting Diode displays mounted on the steering column. An additional side-attraction within the Hyundai exhibit was a kids' soccer area.
