still fuel efficient is kiki more thn cowrola. we have an at city 10 for home use which gives 10.5km/l with 100% ac(as fuse of windows got blown due to stupid chu chu remote installation last year till now didnt had time to diognose the problem:/ ) i have manual 09 city it gives me 15.6km/l with heavy n normal foot.
corolla is more heavy, comfortable, durable, n some how fuel consumption will almost be the same. though u can go for gas in at city as its not a vario tranny, not sure about the 1.6.
if ur drive is on motorway or carpeted roads go for city as u will enjoy driving it n it also have 50% better ac thn ALTIS yes ALTIS 1.8. but if u have kacha paka road traveling thn go for corolla even if it gives much less average. u will curse ur self driving a new city on un carpeted road. u can even feel the texture of road n every single bump in ur head in this car. corolla will glide on it like a glider.
