[edit] Criticisms

I believe there are many issues that GM conveniently ignores in the judging of this competition. Three of which fall under fuels.

1. Hydrogen is 100% well-to-wheel efficient. 2. E85 effectively displaces 85% of gasoline. 3. B20 effectively displaces 20% of diesel.

Hydrogen wins. Ethanol takes 2nd. Biodiesel fails.
