The new Haas Formula 1 team is also scheduled to launch its car on the same day, while Williams' FW38 will be debuted on the Monday.
It was also confirmed on Monday that Sauber will not introduce its 2016 car until the second test, which begins on March 1. It will attend the first test with its 2015 challenger, the C34-Ferrari.
