I am very close to making the plunge and getting a Nissan Altima Hybrid, but had a quick question I can't seem to find the answer to.

The state hybrid tax credit here (Oklahoma) depends on the percent of power the car draws from the electric motor (I suspect on average.) Does anyone have that number?

Specifically, the credit is half of the cost of the vehicle, limited to the portion of the vehicle propelled by electricity, or the percentage of time the vehicle operates solely on electricity.

Thanks in advance for the help.
