The Xprize did away with the emissions test.

But maybe there are other fuels like Hydrogen that pollute less or not all because of their chemical make up?
At least with the original idea of running an FTP-75 cycle. In the end, it was a simple calculated grams per mile of CO2. By leveraging the bio-content of E85, Edison could show a "clean engine path". Meaning, they probably could pass the FTP-75 with a bit of work. They also could leverage the high octane of E85 to increase specific power and efficiency.

With the efforts to produce ethanol from cellulose sources, E85 could become a much more viable option. Thus, Edison could make the case for a fueling infrastructure.

Hydrogen is a clean fuel, if you can overlook the problems in production, storage and transport.
