How does a HCH qualify for 2006 tax credit?

To be eligible for the tax credit, a vehicle must meet the following requirements

- It must be powered primarily by an electric motor drawing current from rechargeable batteries, fuel cells, or other portable sources of electrical current.
- It must have at least four wheels and be manufactured primarily for use on public streets, roads, and highways (vehicles exclusively used on rail or rails do not qualify).
- It must meet all federal and state emissions requirements.
- It has never been used as a nonelectric vehicle.
- You must purchase the vehicle new and for your own use, not for resale
- You must drive it mostly in the United States.
- Government agencies, tax exempt organizations, and foreign entities are not eligible.

The first point, must be powered primarily by an electric engine? This is not the case of any hybrids listed on this board. So who qualifies?
