Hybrid buyers are a fickle bunch. Toyota seems to sell all the Prius models they can build, yet luxury hybrids like Lexus’ HS 250h sit on dealer lots month after month. When Lexus announced that they were launching the CT 200h in the U.S. market, I’ll admit to scratching my head. If Lexus couldn’t sell the HS 250h, I wondered, what made them think they could move the CT 200h in substantial volumes?
