Maruti suzuki swift is a superb car. with great mailage great performance and also give the great grip on road while driving. I am using it since 3 year and I never found any problum in it. Superb car.if you drive on high speed like 140 160 kmpl so the average of the car may be diffrent from the normal because of high speed. But the controlling of the car on any speed will be perfect. The car give you superb milege if you drive it on normal speed like 60 to 80. And if you will not change the gear again and again so the milege of the car will be too good. In the petrol it give 18.5 and an disel it give 19 approx.and the main part is the swiftvdi model is the best. This is the best car ever and it’s prize is affordable.
