Mercedes-AMG will support its customer teams in the DTM this year, marking a return to the series for the first time since its factory exit in 2018.
Autosport understands that Mercedes' support will not be limited to just spare parts and supply of factory drivers, but could also include providing additional funding to customer teams.
Although Mercedes stopped short of revealing how many teams would benefit from its involvement, it is understood that the German manufacturer is interested in supporting four to five cars in the series this year.
So far, GruppeM is the only Mercedes customer to confirm that it would compete in the DTM this year, with plans to field a single AMG GT3 in the series.
Following Mercedes' announcement, three German manufacturers have now pledged their support for the new GT3 era of the DTM, with Audi and BMW having already made a commitment last year.
Ferrari will also be represented in the DTM this year, with Red Bull fielding a two-car entry run by AF Corse for its Formula 1 test and reserve driver Alex Albon, Liam Lawson and Nick Cassidy.
Lawson will drive the Red Bull-liveried entry for the full season alongside his primary campaign in FIA Formula 2, while Albon and Cassidy will share the second entry carrying the colours of AlphaTauri.
"To the strongly contested series in which we were already present last year, the DTM will now be added, another series with a long tradition to expand our international involvement," Stefan Wendl, head of Mercedes-AMG Customer Racing, said.
"From my perspective, we are in a very good position for all the upcoming challenges with the Mercedes-AMG GT3 and the Mercedes-AMG GT4, both in terms of our goals at the real-world race tracks and concerning our involvement in sim racing."
Mercedes also announced its full factory driver roster for GT3 and GT4 categories, with Maximilian Buhk, Maro Engel, Maximilian Gotz, Thomas Jager, Raffaele Marciello and Luca Stolz all retaining their places from last year. They will be joined by new recruits Daniel Juncadella and Jules Gounon.
Mercedes has enjoyed a long history in the DTM but pulled out of the category at the end of 2018 season (above) to race in Formula E.
However, the move away from Class One rules in favour of GT3 cars, triggered by Audi's exit, has lured the Stuttgart-based manufacturer back to the DTM.
