The Formula One community arrived here in Budapest under a cloud following Bianchi's death on July 17 from the injuries he suffered during last season's Japanese Grand Prix.
But his contemporaries vowed to race on in the Frenchman's honour and they delivered one of the finest races in recent seasons.
Sebastian Vettel (right), who started from third, went toe-to-toe with Lewis Hamilton on the 180mph run down to turn one before taking the lead and he never looked back.
"This victory is for Jules," Vettel said. "We know this has been an incredibly tough week. It has been difficult and this one is for him."
Hamilton appeared flustered by yet another poor start and he attempted to pass Rosberg at the chicane, but the move failed. He stepped on to the grass and then ran across the gravel before rejoining the track in 10th.
Red Bull pair Daniil Kvyat and Daniel Ricciardo finished second and third respectively, with Hamilton finishing sixth and Rosberg in ninth.
Hamilton leads the Formula 1 standings from Rosberg by 24 points with Vettel in third, 42 points behind Hamilton.
