The date of the Haas presentation is known
The American team owned by Gene Haas will unveil its new car in Barcelona just before the start of the first week of winter testing.

We finally know the date and location for the presentation of the new Haas. Following the VF-19, the team has named its car VF-20 this year.
Unlike last year when the American team was the first to unveil its new creation, we will have to wait until February 19 at 8:00 a.m. this year to discover the new livery. This presentation will take place 15 minutes before the Alfa Romeo unveiling and on the very day the winter testing begins.
This year again, Romain Grosjean and Kévin Magnussen will be driving this car powered by the Ferrari hybrid engine. However, the 2020 livery is expected to be different from last year following the end of the partnership with Rich Energy. The black and gold color scheme should disappear in favor of a more classic livery with red, gray, and white used in previous years by the American team.
As of now, eight out of the ten teams have announced the launch date of their new cars. Only the Red Bull and Williams teams still leave uncertainty about their launch dates.
