Fuel efficiency is the main problem in the iMT version, I am getting 8-9 km mileage in the city and 13 -14 km mileage on the highway which is very less compared to other brands available at this price tag.
Manual version zis gives good mileage of 13-15 in city conditions and 19-20 on highway driving.
Keep the mileage numbers in mind before buying the iMT version.
