AlphaTauri will unveil its 2021 challenger on February 19.
The team is the fourth to announce plans to reveal its car ahead of the new season, with McLaren hosting an event on February 15, Alfa Romeo February 22 and world champions Mercedes waiting until March 2.
The AT02 will be driven by last season's Italian Grand Prix winner Pierre Gasly alongside highly-rated Japanese rookie Yuki Tsunoda, who has recently completed tests in a 2019 Toro Rosso at Imola and Misano.
The first day of pre-season testing takes place in Bahrain on March 12, with the season beginning two weeks later.
