David Schumacher, son of ex-Formula 1 driver Ralf, will contest the full FIA Formula 3 campaign with Charouz Racing System in 2020, alongside new team-mates Igor Fraga and Niko Kari.
Having raced in the Formula Regional European Championship last year, in which he finished fourth, David Schumacher contested the FIA F3 season finale at Sochi with Campos Racing.
He remained with the series for the Macau Grand Prix with the Charouz team - rebranded from the Sauber Junior Team - which he now joins for 2020.
"I feel really happy and grateful to make the step up to FIA Formula 3 full-time with Charouz," he said.
"I drove two events at the end of last year and that was good preparation for the season ahead.
"I got to learn more about the car, and that's valuable as we don't have many practice opportunities during race weekends.
"I think we can make a step forward this season and I will try and finish as high as possible."
Regular Esports driver and former Brazilian F3 class champion Fraga is leading this year's Toyota Racing Series, which finishes later this month, against strong competition, having finished third in Formula Regional last year with the DR Formula team.
He added: "I'm really looking forward to joining the Formula 3 field with Charouz.
"It is a competitive series and a very professional environment - running at the same events as F1 is kind of crazy to think about.
"I just can't wait to start my season.
"This year is about the process of learning.
"Of course, the goal is always to win a race, but I am not underestimating the challenge ahead either. I will give my best and push to achieve my goals."
Ex-Red Bull junior Kari won the SMP F4 championship in 2015 and has raced in European F3 and GP3 (now merged into FIA F3) ever since. His best finish in GP3 is 10th, and last year he took 15th with Trident.
"I'm really looking forward to this year," said Kari.
"It will be a nice challenge to go and fight for podiums and why not for the championship as well?
"It's going to be an interesting journey with Charouz and I'm sure we can work well together.
"I want to improve myself as a racing driver and Charouz is a very professional team.
"I'm hoping this can be the start of a long-term relationship and that we can make a good season out of it."
