December 3, 2006 GM Advanced Design has won the Los Angeles Auto Show’s Design Challenge for the second year in a row. This year’s winning entry is a two-dimensional rendering of a 2015 Blue Sky Concept that addresses environmental sustainability. Called the HUMMER 02, the design was created to demonstrate that daily use of a vehicle could result in a net gain for the environment. The HUMMER 02 Concept features a phototropic body shell that produces pure oxygen throughout the life of the vehicle. Algae-filled body panels transform carbon dioxide into pure oxygen that is subsequently released back into the environment and inside the vehicle.
