I am using Baleno Delta petrol since 2016. I drive in city approx. 60 kms per day. City mileage is 13 km/l. I occasionally drive on highway on an avg speed of 100 to 120 kmph. Highway mileage is 18 km/l. I would say it's a good value car on prime hatchback segment. Love the old model design. The new design looks poor :( Bad move by maruti in making changes with a successful design.
