The Alfa Romeo name will return to Formula 1 in 2018 in partnership with Sauber and Ferrari.
Sauber will now be known as the Alfa Romeo Sauber F1 Team, and the deal will include "strategic, commercial and technological cooperation" and "the exchange of engineering and technical know-how", said a team statement.
Great news in my opinion and a great boost for Sauber.
