Currently, the F1 season is scheduled to begin with the Canadian Grand Prix in June, though that is expected to be postponed too.
It would mean that the season gets underway in France at the end of the month, though July could be more likely with the Austrian Grand Prix taking place on the 5th. The country is set to become the first European nation to lift lockdown measures.
Formula 1 teams have switched focus in the meantime to helping combat the virus, with Project Pitlane aimed at aiding those in need due to the COVID-19 outbreak. Ventilators and assisted breathing devices have been prioritised since the original shutdown came into effect last month, and Mercedes today announced its innovative breathing aids have gone into production, with 1000 units made every day.
