I just returned last Friday to Karachi from Kalam on my Alto 660C. We were four kids and two adults, and the car performed very well without breaking a sweat. After Bahrain, there are some patches where you will need to use Sports mode and traction control. The road is okay, but since the flood, the bad patches have increased in number. If there is snow on the road towards Malam Jabba, which wasn't when we were there, you can rent snow chains. Have a safe journey.
