Toyota has confirmed that the Sai hybrid, a Toyota based on the Lexus HS 250h, will be available for sale on October 20th.  The Toyota Sai will most likely come with the same 2.4L HSD engine that is included in the Lexus HS 250h. And, like the HS, that increase in power will equal lower fuel efficiency (the HS gets 35 combined MPG). The Sai has a revised grille (with less chrome) and a new lower fascia and wheels. Different taillights distinguish the Toyota from the Lexus and, inside, there are fewer buttons and a revised mouse control.
