Hi folks,
I found this chart attributed to CNW Marketing:

"Percentage of new-vehicle shoppers who would consider buying a hybrid"
"Source: CNW Marketing Research Inc."
This reference was found in:

What is interesting is the demand defined as "consider buying a hybrid" remains about 3x the percentage of sales, assuming at most, 5% of all vehicle sales are hybrids.
