Alfa Romeo Sauber is the latest team to set a date for the launch of its 2018 challenger.
The covers on the C37 will be pulled off on February 20, the team confirmed on Monday.
Thanks to a renewed deal with Ferrari and a title sponsorship deal with Alfa Romeo, the Swiss outfit will be powered by a current-spec Ferrari power unit, having previously run year-old units throughout the 2017 season.
The C37 will be driven by Sweden's Marcus Ericsson and 2017 Formula 2 champion Charles Leclerc, with Ferrari-affiliated Antonio Giovinazzi lined up in the reserve/test role.
After finishing 10th in the Constructors' table in 2017, with just five points, Sauber is looking to push forward and re-join the midfield runners.
The team is currently scheduled to be the second outfit to break cover on their 2018 challengers with Williams taking the covers off the FW41 five days prior.
Pre-season testing gets underway on February 26 at the Circuit de Barcelona-Catalunya.
