It's not uncommon for the first year of a new car design to have large differences between teams, things should be closer next year as teams make improvements. This weekend looks like it's shaking things up already, Ferrari is extremely close. Schumacher and Stroll both made it to Q3 for the first time this year if I'm not mistaken so midfield is getting shaken up too. Not making a mistake on the track or on strategy is going to win it tomorrow, it's not a forgiving track because of lack of paved overruns and the sand that tends to blow onto the track and make it slippery outside the racing line.
