Interesting to see how different track characteristic, track temperature and a bit difference tire compound could make such a drastic difference.
Last week Alonso was untouchable in Shanghai with front limited tires and slight cooler track temp. In Bahrain, its totally different and we see Vettel won in similar fashion this weekend.
But I still reckon if Alonso's DRS was functioning properly, he would at least be on the podium. That makes VET, ALO, and RAI the usual suspects on the podium.
