The most competitive end of the automotive market happens to be the smallest car segment also called the A-segment. This is the compact hatchback segment dominated by the Maruti Alto with other fringe players like Hyundai Eon and the Datsun Go clutching at the straws.
Breaking through this segment isnt easy, volumes may be high but value low and at the end of the day what customers are looking for more than anything is overall ownership value. That is a terribly hard thing to come by where pricing at all stages is highly critical and none barring Maruti have managed to surpass expectations.
