Replying to this question here in this thread would be off-topic. I would be happy to discuss this again in another appropriate thread though.
My 2009 Corolla with the same 1.8 liter engine (I think) as the Pakistani Altis and a four speed automatic gearbox gets about 27 mpg US in the city and about 37 mpg US on the highway on regular fuel.
That comes out to about 11.4 km per liter city and 15.6 km per liter highway.
With a full tank, the car can easily travel more than 650 km ( i.e. over 400 miles).
