A draft 21-race calendar released by teams and broadcasters sees Mexico City join the Formula 1 line-up for the first time since 1992.
The calendar – which must be approved by the International Automobile Federation in September – has the most races in the championship’s history.
Like Mexico, Grands Prix in Sochi and South Korea would each be subject to track approval, with Austria returning to the calendar and India dropped from the schedule.
The season will start in Australia in March and finish in Brazil in November.
