Toyota Corolla Altis has no chances of coming with a sunroof as the current top model has every other feature than the sunroof. Toyota may add sunroof in the next generation of Altis but an optional model with sunroof has not been discussed anywhere in the current market scenario. The engine in the Altis comes to be the 1364 cc, D-4D which produces only 87 BHP. The power value seems to be quiet lower than the values in the competition.
