I actually took the picture of this car because it was a neat display (and the other side of the car was MOE green
). I did talk to the rep about their fuel cell prototype car, but that was a bland color.
If you look closely, and you may not be able to see it in this pic, the yellow is actually painted to look like rows of corn kernels.
The rep did say to someone there that E85 is just a temporary solution to the gas crisis and more work is being done to improve cost and efficiency.
