"We are pleased to extend our technical partnership with Ferrari taking Sauber into the new era of engines that starts in 2014," team boss Monisha Kaltenborn said. "Ferrari has been a long standing partner of the team, first from 1997 to 2005 and then again from 2010 onwards.

"We are proud to extend our relationship with such a prestigious and renowned brand and look forward to entering the 2014 season with a strong and reliable partner like Ferrari."

Sauber joins Marussia as a Ferrari customer team for 2014, leaving Lotus as the only team on the grid still to confirm its engine deal for the introduction of the new 1.6 litre turbo-charged units.

The Enstone-based team is expected to remain with Renault however alongside Red Bull, Caterham and Toro Rosso, with the remaining four teams all using Mercedes power.
