Wagon R performed good. But keep the ac off while mounting up. Motorway was constructed till abbotabad Maqsood interchange. Avg. Speed throughout the journey on motorway was 120.use Low "L" gear while decelerating down from heights. As it's 660cc vehicle therefore pick up was slightly low while mounting up. Any vehicle which could climb up the Monal Islamabad could easily go till Naran or even far than Naran.
