Cylinder deactivation also works around town. In the Hybrid Accord, it normally runs on 3 cylinders, but switches to 6 when you ask for hard acceleration.
Ahh I see. But still, shutting off all the cylinders would be better =) The Previa is not the same as the Sienna sold in North America. It is the same as the Estima sold in Japan. The Sienna is unique to North America while the Previa/Estima is sold everywhere else
