HMM: Report: Toyota to limit U.S. Prius V to five seats, other markets seat seven. “Toyota spokesman John Hanson gives several reasons for this decision, but two stick out above all others. Perhaps most important is the fact that the U.S. version of the V will come only with a nickel-metal-hydride battery pack, which takes up a lot of room in the hybrid’s hind-quarters to offer a sufficient third row. The Euro and JDM models will feature lithium tech, which is smaller and more compact.”
