i have a lancer 1.6glx auto so i can give you exact details
with ac it will do 7.5 to 8 in city .who ever says it can do more than 10 is wrong . i have tried to drive it at very low rpms and still the best i got was 8 with ac in summer.
ride is very good.much better than any local assembled car
you have to run it on mixture of hioctane and super other wise it will do knocking with ac (dewan people also recmends that)
what ever you do,dont buy from mitsubishi defence moters
they are a bunch of unprofessionals who cant even retune the ecu for the local petrol
