I bought the Elite i20 petrol version month back. Drove 300+ kms. i 20 is best in comfort and ride quality. I saw reviews about this car and worried about mileage after booked the car. Once i started driving i see the surprising result in mileage( got 22.3 KMPL in Highway and city 15 KMPL)
Note: Maintained consistent speed to check the mileage in highways( 70 to 90 and RPM 2000 or less)
