Italian F4 champion Ralf Aron will move up to European F3 with frontrunning squad Prema Powerteam.
The 17-year-old Estonian took Prema to its second Italian F4 drivers' title in two years - the first having been won by Williams junior Lance Stroll, who will be a teammate of Aron's in F3 next year.
Prior to his Italian F4 title, Aron impressed on the Formula Renault 1.6 scene, finishing runner-up in the NEC series and winning five races in a part-time campaign in the STCC-supporting Nordic championship.
"I am very happy to make the step from Formula 4 to Formula 3 and especially with Prema," Aron said. "We had a fantastic season together and I am grateful for the opportunity, hopefully I can make them proud again."
Aron and Stroll are the two confirmed drivers in Prema's four-car 2016 line-up. They were set to be joined by Ben Barnicoat, his deal with Prema having been officially announced by the Racing Steps Foundation on British television.
However, Barnicoat has recently tested with other F3 teams, putting the deal in doubt - with Prema trying out other hopefuls Nick Cassidy and Maximilian Gunther instead.
