A rumour (i believe its true) has been around for quite some years.... They say, big 3 are under an understanding among themselves that who will cater\focus on which market.
Suzuki for hatchbacks
Honda for executive "premium"
sedans
Toyota for rental sedans "the XLIs"
, with an ounce of Grande
Since Kia is also a big competitive player among the 3...so they are focusing on an entirely new segment of crossover and leading in it, with an ounce of hatchbacks (to not interfere with Cultus sales much)
If you look back, Suzuki never willfully marketed their sedans, margalla, baleno, liana, ciaz... All worthy opponents of rolla, city.
IM brought cuore, but never marketed\pushed it much.. they could easily moved to an efi engine in 2012, when mehran did.. but ofc.. mehran is Boss.
IM could easily put vitz in competition of swift
Kia could easily put cerato in competition of City\yaris
Kia could easily put rio in competition of swift
Hyundai could easily put their i10 hatch in competition of Cultus
Bhai, its all just an agreement among these companies, so that sab mil baant ke lootein.
