Honda improved it. Toyota "perfected" it.
Bunk! Honda perfected the ICE while Toyota fags put out all efforts and money into Prius. My brother in law has bought Prius. I told him this is a totally new Toyota independent division w the best engineers that Toyota would poach, that Toy would not mind taking losses on.
Guess what/ 70% of his Prius miles are on the highway. IOW ICE on a 95 HP motor..... lol another hybrid fake out!
