The Swedish Ferrari junior had a tough race last weekend at Monza, where he did not score any points at all, but now took the chance for quick revenge.
He started Sunday's F2 race from pole position, which he then held throughout the race.
The 22-year-old Swede won by seven seconds over runner-up Irishman Alex Dunne, and thus climbs to sixth place in the overall standings.
There are three race weekends left in the F2 series.
