F1 Azerbaijan GP: Updates and Analysis.

The FIA has shortened the DRS zone for the Azerbaijan Grand Prix in Baku by 100 metres, reducing the distance the drag reduction system can be used on the main straight. The move is in line with F1's efforts to fine-tune the balance between improving the show and making overtaking too trivial. Baku is the fourth of five F1 circuits to have undergone tweaks to the DRS zones. The Baku City Circuit has also been resurfaced ahead of its sixth running of the race.
