I have recentlt bought nexon xm in the ver beginning i drive it in city on eco mode abot 400km in 2 weeks i get average of 8 kmpl my daily round was aprox 25 30 km. Then i drove it to chd to bareilly and then return it was about 1000km + round trip . And on eco i get average of 13 km . Mid showing 15 but i calculate it by refueling . 1st service done . I remark this complaint to tata they told that after 4th service the car going to give u average . Till now i have refuel tank of 42k + in just 4 months . Its fuel economy is worst than i thought. And the interior is not that good. + the ac is not that effective.. and it lacks power in city and eco. Other than that. The quality design storage is awesome .. out of 10 i give 6.5
