Toyota is reportedly looking to parlay the popularity of the Prius into a whole new line of vehicles under a possible Toyota sub-brand. This sub-brand would be made up of a line of hybrid vehicles including a Hybrid SUV and a Hybrid Station Wagon (pictured above).

With hybrid vehicles gaining popularity in the U.S., larger hybrid versions of the popular Prius might satisfy that American need to size and storage capacity. Soccer mom’s alone could justify a Toyota Hybrid Station Wagon.

According to a Japanese newspaper, Toyota executives are looking at using lithium-ion battery packs for the upcoming line of hybrid vehicles, even though Toyota has in the past stated that they felt lithium-ion batteries were too expensive.

There is still a great deal of speculation surrounding this possible new line of eco-friendly vehicles, so stay tuned as more details come forth.
