i havent taken it to murree side, but i have experienced it on Pir sohawa roads,
its pic is very good n responsive.
we were 5 ppl (60-75 kg each) in the car, and it gives no problem, it climbed up the hills very well in 2 and 1 gear,
actually most of the time while gng upwards, i put it in 2 (D2) mode, so it stays in 2nd gear normally, but when it needs to climb up after all the sharp turns of pir sohawa, it goes into 1st gear, when i push the pedal a lil more.
also it has given me about 11km/ltr average while gng up( from zoo to monaal)
