Gianni Morbidelli took his first Superstars International Series win of the season at Zolder, while Laurens Vanthoor stole the show with a stunning drive from last to second.
Starting from pole position on a greasy circuit, Morbidelli's only challenge was holding off the more powerful Mercedes of Tonio Liuzzi on the run down to the first corner.
Having successfully held on to the lead, he then let the four-wheel-drive Audi Sport Italia RS5 do the rest of the work, pulling 2.8 seconds on the field on the first lap alone, before leading all the way to victory.
Vanthoor made it an Audi one-two, but his race was far less straightforward.
With a transmission problem in qualifying leaving him starting off the back row, the Zolder local had it all to do in the 25-minute race, and he wasted little time.
By the end of the first lap, he was 10th. By the end of the second lap, he was sixth. With eight minutes of the race left to run, he was in second and catching Morbidelli.
In the end it was not enough to win, but it was still the most impressive drive of the race.
Luigi Ferrara's Roma Racing Mercedes was the best of the rear-wheel-drive cars, finishing a lonely third, ahead of impressive debutant Renaud Kuppens' Scuderia Giudici BMW.
Liuzzi had a quiet race on his way to fifth, with Raffaele Giammaria and Fabrizio Giovanardi following him home.
Giovanni Berton, Thomas Biagi and Nicola Larini rounded out the top 10.
