Suzuki is the dumbest auto manufacturer in the world and in pakistan their stupidity is high like K2. There is a solid reason why they went bankrupt in America.
They sold old EFI cultus for several years with user manual written for 3 cylinder carby cultus. These idiots are still selling "kamani wali Mehran" with only two AC ducts calling it Euro 2/4 EFI Mehran and I am sure if it is tested according to real Euro standards, it will fail all emission tests.
These idiots are calling Mega Carry's speedometer a "safety feature" on their site. Check the screenshot below.
So don't believe whatever crap is mentioned on their site. It is not 100% correct. New Cultus aka Celerio got same K-Next (Next Gen K10B) engine which is installed in Celerio in other countries. (This engine is directly imported from Indonesia or Thailand). Overall quality of body, paint and other parts might be lower than international variants but the engine is same.
And also do not do the mistake of buying Wagon R engine parts for New Cultus. They won't fit properly.
