Hello,
For the expected running mentioned and drive most on highways - you are going to get good mileage in Petrol too
For 12,000 Kms, with 70% drive on highway running on Petrol - if driven at controlled speed can give you mileage of 16 Kmpl in Petrol
Yes, the price difference is not huge, But Hope you are aware of some of key points in Diesel
- Grand I10 Diesel comes in smaller 1.1 Lit Diesel Engine, which is slight underpowered in terms of Engine Power & Torque - if compared with Swift
- Diesel historically has higher maintenance costs (Fuel Filter, Engine Oil, Air Filter) and even some spares are priced higher too
- Insurance Premiums comes with virtually negligible OD Discounts after 3 yr in Diesel and has higher premium to it
- Noise of Diesel Engine is relatively much more than the silent K Series of Swift or VTVT Kappa Engine of I10 Petrol
As you have taken Test Drive - Did you observed any difference in outside view from Grand and Swift. Why ? I felt that the outside view of the car seems obstructed bit by high mounted dash
(though my height is 5'11). Worse, the seats are not height adjustable in Sportz Variant
(Asta however has)
Presuming - you did not had any discomfort, will recommend Grand I10 Sportz over Swift , Especially the features makes it a real value buy
You can read on comparison of details which we posted in one of the previous thread -
Swift Vs Grand I10
Hope it answers !!
