Sauber has announced a major partnership with a trio of Russian companies that will secure the team's long-term future in Formula 1.
The companies involved are the Investment Corporation International Fund, the State Fund of Development of Northwest Russian Federation and the National Institute of Aviation Technologies.
AUTOSPORT understands there will be no change either to the shareholding of the team or the management.
"We are pleased to announce a partnership between the Investment Corporation International Fund, the State Fund of Development of North-West Russian Federation and the National Institute of Aviation Technologies with Sauber Motorsport AG, incorporating the promotion of the sport Formula 1 in Russia and jointly developing high-technological solutions," said a Sauber statement.
