Sauber has partnered with Charouz Racing System to launch the Sauber Junior Team, which compete across the lower ladders of single-seater racing.
The newly-formed junior team will compete in Formula 2, International Formula 3, German and Italian Formula 4 series with full technical, sporting and commercial support from the Hinwil-based outfit.
Sauber Junior Team will be conducting their first tests across three days after the weekend of the Abu Dhabi Grand Prix from November 29 until December 1, when Formula 2 testing takes place.
Antonín Charouz, team owner of Charouz Racing System said: "Establishing a Junior Team partnership with Sauber Motorsport is a proud moment in the history of Charouz Racing System and we’re looking forward to taking some exceptional drivers on track in 2019, across three different categories of racing.
"The Sauber Junior Team programme is a very exciting development in international motorsport. It gives drivers the chance to potentially progress all the way from Formula 4 to Formula 1 with a single team.
"That’s a unique model and an exciting prospect for everyone involved."
Sauber boss Frédéric Vasseur added: "Racing is a vital part of Sauber Motorsport’s DNA and the Sauber Junior Team marks an important milestone in the company history.
"Sauber has a long tradition of helping drivers reach their full potential, having worked with the likes of Michael Schumacher, Sebastian Vettel and upcoming star Charles Leclerc.
"With this project, Sauber further extends its racing platform with a complete and dedicated programme from the junior series to the pinnacle of motorsport.
"We are delighted to partner with Charouz Racing System, a highly professional team that operates with success in all the series."
Charouz, which previously competed in Formula V8 3.5, entered Formula 2 this year, fielding Ferrari junior Antonio Fuoco and Louis Deletraz, who will test for Haas in Abu Dhabi later this month.
