Depends which type you gonna buy. Automatic or Manual. 4G13 12 Valve 1300cc engine or 8 Valve 1500cc engine.
Its slightly varies for sub-model to sub-type.
Further fuel consumption does not depend on single factor. This is something which is in your control actually. Feed good quality and recommended fluids, change them timely,…. driving habits, daily route, etc. etc. so many things count.
I had Lancer 1991 model 1300CC 12 valve engine Manual. And it gave me 10 km/l within city with & without AC. And 15~16 on highways.
2005 model is definitely better than this.
