While not as tumultuous as last year, the 2021 Formula 1 season has already proven to have its fair share of shake-ups (Mercedes trailing Red Bull, for example), and we’re only seven races in. Now, two more big changes have been announced this past week: Turkey will be returning to the calendar and Abu Dhabi’s Yas Marina circuit will be getting a minor redesign. Regarding the former, the Turkish Grand Prix had originally been scheduled for the weekend of June 11-13, but Coronavirus travel restrictions led to it being axed. Since then, a second race in Austria has filled its spot, but now it will rejoin the calendar to fill the gap left by the cancellation of the Singapore Grand Prix, which was originally set for the weekend of October 1-3.
