Altis has sunroof (optional), 6-speed (for MT), better looking steering wheel with 4 spokes, cruise control (optional), better looking odo with more features and information, better looking under the hood view, flat floor (on the back side), more luxurious looking interior, driver air bags, side skirts, retractable mirrors, auto rain detection wipers ( optional), better sound system, navigation and multimedia system with rear view camera, company fired alloy rims, company fitted fog lights, colored side mirrors and door handles (currently not even gli is offering this), and ofcourse a bigger engine displacement (1600 cc) coupled with dual VVTi.
There are basically 4 trims of altis. The features noted as optional above vary depending on the trim, else all other features are standard. This is in addition to all the standard features of a GLi.
Hope this answers your question. And I think your title should have been "Difference between Altis and GLi". Because technically Altis is also a corolla.
