I think Toyota is ahead of
I think Toyota is ahead of the pack by a country mile. The RAV4, Venza (which is basically a RAV4), Sienna, Highlander, Camry, Corolla, Prius - All available as hybrids and they are selling robustly. All of General Motors has zero. Ford has some but sales are trending to zero and the PHEV Escape is pushed out till next year. Acura, Infiniti, Buick, Cadillac, and many more brands don't have a single car that outsells the Prius. Imagine that!
