Poor milleage , good suspension, handling ,AC

Unexpected low milleage of 13.85 to 14.66 rated on tankfull to tankfull . Do not expect a Matiz space which is brilliant . This car is closer to Alto size but better lugage space. Ride ,comfort and noise level is superb and handling also stable . There is good power for overtaking but not the friskiness of Matiz . BIG disapointment is milleage .My best milleage was after carefull driving on highway for 60% and AC on 40% .I used to get 17-18 km/l on Matiz .So owners of Spice Version hold on to your car. AC cooling very good . I have done 890kms on model LT Option .Will give further feedback after servicing and any tweaks if possible .Ride ,comfort and noise level is superb and handling also stable . There is good power for overtakinUnexpected low milleage of 13.85 to 14.66 rated on tankfull to tankfull . Do not expect a Matiz spa
