At the 2011 Detroit Auto Show, Toyota expanded its Prius line with the addition of the Toyota Prius V family hauler. Next year, Toyota will add a Prius city car with the ‘Prius C‘ nameplate. Of course, there is no desire for the Japanese automaker to stop there.

Well, the ultimate decision is up to you. Cast your vote at http://www.toyota.com/priusfamily and give Toyota a hand in figuring this one out.
