The Sauber name will disappear from Formula One this season after more than 25 years with their announcement that the team will be renamed Alfa Romeo Racing.
Swiss Peter Sauber, now retired, founded the team in 1970 and then celebrated his debut F1 season in 1993.
The Sauber team has been using Ferrari engines for some time and had a collaboration with Alfa Romeo last season. Like Ferrari, Alfa Romeo belongs to the Fiat Chrysler Group.
"It is a pleasure to announce that we will enter the 2019 Formula One world championship with the team name Alfa Romeo Racing," team principal Frederic Vasseur said in a statement.
"After initiating the collaboration with our title sponsor Alfa Romeo in 2018, our team made fantastic progress on the technical, commercial and sporting side."
Sauber were eighth in last season's championship.
Kimi Raikkonen and Antonio Giovinazzi will drive for the team this year.
