Hyundai has revealed the first pictures of the BLUE-WILL, a plug-in hybrid concept car the automaker will reveal at the Seoul Motor Show on April 2nd, 2009. The car's parallel hybrid system features a 1.6-liter direct injection gasoline motor, a 100 kilowatt electric motor, a continuously variable transmission, and a lithium ion polymer battery pack.

The lithium ion polymer pack is the first use of the technology in a production car, according to Hyundai, and is situated next to the fuel tank underneath the rear seats to maximize storage space in the trunk. The car also has a panoramic roof which integrates dye-sensitized solar cells in order to regenerate the batteries without blocking the view. Various parts of the car will be made from recycled materials, including bioplastics, plants, and soft drink bottles and will also be bio-degradable.
