For informed people , vehicle classes are defined by body style & characteristics such as Hatchback, Sedan, Suv etc.
For rich & uninformed people, vehicle classes are defined by price range such as <5 Lakh, <10 Lakh etc.
Hence though an SUV is ideally not supposed to take away sedan customer, but In India any thing is possible.
Have anyone wondered how D segment car sales are dwindling after the launch of super successful XUV 500.
So I MHO Duster can eat away some customer from C segment sedan. The effect would be minuscule because I dont think Duster would be a successful model at first place. But had it been better priced (less than 50 k across the diesel variants), some probable Vento & Verna (top diesel variant) might have switch over to Duster.
1. Because In India's traffic condition it is actually much easier to drive a SUV/MUV/UV than a sedan. They offer better view of the road and our roads being fulled to the brim, view of every inch of the road become essential.
2. Additionally, since our roads are full of potholes so vehicle with better GC is always welcomed.
3. In our roads (filled with drivers of terrible road sense) it is very difficult to drive above 100 kmph where a sedan convincingly trumps an SUV. So below that speed, handling characteristics is not much noticeable. BTW
, IMHO it would be comfortable to drive a Duster above 100 kmph than a Verna.
