In what setting. The last time I ever measured it was around 13km/ltrs, the car was on AC and fully loaded with 3 people at the back and a CNG cylinder, AC was on and on average the car was driven at around 4000 rpm. I think if driven at around 3000 rpm and also with 2 people 15km/ltr can be achieved on highways but in city I think it can be around 10-12km/ltr
