Is there a hybrid minivan out there?

With 137,000 miles on my 2000 Toyota Sienna minivan, it’s going to be time soon to get a new car.

I want to get a hybrid so I can use less gas and feel less pain as it climbs past $4. But as far as I can tell, there are no hybrid minivans out there.

Toyota may be releasing a hybrid minivan next year, but according to Hybridcenter.org, a project of the Union of Concerned Scientists, they may not, even though they have some in Japan. I was intrigued to read Toyota received 18,000 signatures on a petition asking the company to bring a hybrid minivan to the U.S.

So if I can’t get a hybrid minivan, what is the biggest car I can get with the best mileage to shlep the kids around town?
