ECO idle in corolla? no corolla models yet have start stop technology, new ones are on doubt on fuel economy better but i also find each new 1.8 engine to be dimwitted and slow.
have a 2006 and 2010 1.8 altis, and drove the grande as well, for sheer acceleration the 2006 still felt better and more responsive, the 2010 a bit numb, and the grande also good grunt but the CVT gives a slippery feel in D and if you use paddles the gears are short shift so you have to constantly flick pedals to downshift to a acceptable gear. the combination of more weight, more busy tranmission and eco and other electronic nannies has reduced the responsiveness and snappiness of the power train with only 5-8hp improvements but good fuel economy bump.
