The littlest Toyota, the Yaris, is about to become hybridized too, and the engineering job to reduce the size of its Hybrid Synergy Drive system for the diminutive car is worth a look. The hybrid engines from the larger Toyotas such as the Prius and Auris were too large for the Yaris as they would have eaten into passenger space, and as the car's catchcry promotes a "small outside, big inside" character, a new powerplant was prescribed.
Toyota was obviously very keen to bring hybrid drive to the tiny Yaris, which is sold as the Vitz in some markets and the Diahatsu Charade in others.
