The DTM has announced a new-look calendar that includes a first visit to Sweden and Hockenheim slimming to a single round, with one "exciting" addition yet to be announced.
Hockenheim will not open the DTM season, or host two rounds, for the first time since the series was relaunched in 2000, with the '20 campaign instead opening at Zolder (pictured above in 2019) on April 24-26.
Following Zolder, the DTM will head to Lausitzring - which has moved from a late-season slot - ahead of the only TBA on the calendar.
A DTM statement said that the series will announce the identity of that its unknown May race at the 2019 Hockenheim season finale next month, with ITR CEO Achim Kostron adding: "We still have one surprise in store. And it's very exciting."
Following months of speculation, former Swedish Grand Prix venue Anderstop (pictured below) is the fourth round of the campaign on June 12-14.
Fellow DTM calendar debutant Monza follows Anderstop on June 26-28 as the Formula 1 Italian Grand Prix venue appears for the first time, following the DTM's decision to exit its Misano contract one year early, after two years at the circuit. It held a night race in 2018 (pictured below) before switching to daylight for this season.
Brands Hatch sits between the Norisring and Assen rounds and has kept its slot on the calendar despite the DTM holding discussions with British Grand Prix venue Silverstone.
Nurburgring and Hockenheim again operate as the final two rounds of the season as expected, although the DTM had been in protracted negotiations with Hockenheim during the season.
"The 2020 DTM calendar reflects our ambition to achieve both growth and stability," said Kostron.
"We'll continue to race at Germany's most popular motorsport venues while also increasing the series' presence across Europe.
"We want to continue growing awareness of DTM in key European markets - so racing at legendary British and Italian racetracks such as Brands Hatch and Monza really allows us to reach those national audiences.
"Equally, our first visit to Sweden next spring will unlock another new and important motorsport market, one that continues to grow.
"While the scope of the calendar keeps growing, we've remained loyal to our fans in Germany, retaining four races at key German venues.
"In addition, the location of both Zolder and Assen means they're both within easy geographical reach for many German fans.
"We feel like we've got a perfect blend of venues and dates, and we're already getting excited about the new season."
DTM Boss Gerhard Berger added: "I'm delighted that DTM will be racing in Sweden for the very first time.
"It's an exciting addition for us, and I'm equally sure that Sweden's motorsport fans will relish watching wheel-to-wheel-racing with these spectacular turbo-charged DTM cars at their home circuit.
"And, personally, I have some very fond memories of Anderstorp: I raced a Schnitzer BMW 635 CSi there in the 1980s - it's a really fantastic track."
There is one clash with Formula E - the yet to be announced round clashing with the Berlin Formula E race - with the DTM keen to avoid overlap with other series.
That means Audi's Robin Frijns and Nico Muller, who was announced as a Dragon driver on Wednesday, will be able to compete in all but one race in both series.
Berger held a fans forum discussion at the Nurburgring in which concerns were raised over the strength of the DTM's support package.
R-Motorsport is in discussions with the series over adding its new-one make series to the grid, while W Series will continue on the DTM package in 2020.
The calendar remains subject to the approval of FIA World Council.
