As a very loyal Toyota customer I am always interested in all the new technology that this company produces. The hybrid car has been advancing leaps and bounds over the past few years. As far as I know a Sienna hybrid is being planned for but has not become a reality. This car line has a few model options for hybrids and I am sure that their is a market for a minivan hybrid. Their minivan is very popular and adding this wonderful technology to this car would be a great addition to their line of cars. We will have to wait and see….
