If they put 1.6 in Kizashi. it will loose its charm, it will become a big fat old lady unable to move:). Kizashi is a luxury car and in my opinion Pak suzuki can't build a good luxury car. It is a car of the segmemt of Hyndai sonata,volkswagon passat,Toyota camry and honda accord, trimming it down will be unfair to it.
To replace cultus they need to launch Ritz(Splash) and A-star to replace alto.
