The Williams FW36 has been the best-of-the-rest during the previous three race weekends, but with the team expecting a tougher time at the Hungarian Grand Prix, specific updates have been introduced for this weekend.
This includes a roll-hoop winglet and revised rear wing, as well as the cooling tail fin that was raced at the German Grand Prix last weekend.
Post-2009, rules have prohibited the rear bodywork from being adorned with cooling outlets, fins and wings. But a few loopholes remain, and Williams has been clever to exploit most of them.
