One of the dual-powertrain variations will be a hybrid RAV4 built in collaboration with Tesla Motors and scheduled to be unveiled at the L.A. Auto Show in November. The plug-in Prius is expected to sell for $3,000 t $5,000 more than a gas-electric Prius, which can run from $23,000 to $33,000.

At least some, though perhaps not all, of the six hybrid models will be sold in North America, which is the world's largest market for hybrid vehicles.
