The Getz 1.1 should constantly get above 10km/L city driving, and perhaps hit 20km/L and above in the highway if driven gently. But if he's used to AE101 fuel consumption, hindi naman siya maninibago sa Sentra since pareho rin namang 1.6 EFI. Perhaps around 8-9km/L.

Unless one has financial concerns, no way is a man gonna downgrade from a 1.6L compact to a weedy 1.1L subcompact hatch.
