Here's what I was told by Toyota. If you haven't done so already, anyone posting here should go to Toyota.com and express their interest in buying this sort of vehicle:

Thank you for your interest in our hybrid technology and for being part of the Toyota family.

We appreciate your feedback that you would like to see Toyota offer the RAV4 as a hybrid because the only way we know what our customers are looking for is when they tell us, as you have. We try to scope our customers out in advance, by researching the market, conducting interviews, surveys, focus groups and doing our homework, but there's no better source than a Toyota owner who takes the time to tell us like it is.

We can't guarantee that a hybrid RAV4 will be made available in the future, but if it were, it would be driven by just this sort of honest communication.

Again, please accept our apologies for your disappointment and our sincere thanks for taking the time and trouble to let us know.
