My 2010 Corolla Xli was doing 510km/full tank AC on and without AC 575km.
This new Xli is not doing so.
On meter it also show 13km/l but this not true.
I never drive it on highway. I bought this car to drive in city(Lahore).
For long drive I use C200 which give 12-13km/l. If no traffic then 15-16km/l.
