Alexander Albon and Liam Lawson will enter the DTM this year with backing from Red Bull Racing.
Albon spent the second half of 2019 and the entire 2020 season racing with Red Bull in Formula 1 but has been replaced for 2021 by Sergio Perez.
Albon, who scored two podiums in 2020 at Mugello and Sakhir, will sink back into a reserve role for this year.
Albon will take part “in selected [DTM] races whenever his Formula 1 duties allow”, and will alternate with another driver, who will be confirmed in due course.
Lawson, 18, spent the last two years racing in the FIA Formula 3 Championship, ending the 2020 season fifth in the standings, picking up three race wins and a further three podiums.
Lawson has been part of Red Bull’s junior team since early 2019 and has raced in a handful of categories in that time, including the Toyota Racing Series, which he won in 2019.
Lawson is poised to combine his DTM duties with a seat in Formula 2.
It has not yet been confirmed with which teams and cars Albon and Lawson will compete in DTM.
Gerhard Berger, who has been the DTM boss since 2017, said: “Formula 1 drivers like Alex Albon, DTM stars like three-time champion René Rast, GT professionals and young talents like Liam Lawson – that is a high-class driver mix the way I would like it for the 2021 DTM season.
“It is also a perfect fit that ex-Formula 1 World Champion Jenson Button has already submitted an entry for the DTM with his team.”
New regulations will come into effect this year, with the previous Class One regulations being scrapped in favour of a GT3-based approach.
The nine-round season is due to begin at Russia’s Igora Park in late May.
