Is it true that the introduction of the new Dzire with reduced length is to enhance the sale of Maruti Suzuki SX4 which had a real competition from the old Dzire. Otherwise they would have continued the old Dzire also in the market.

I had a dream of having a black Dzire VDI earlier. But alas. The dream has shattered because of the new shape. Now I have to switch over to other brand which is is having a conventional shape having a full size boot at least 400 liters. One more doubt. How is the thigh support and the length of new and old Dzire.
