Pedro Piquet took a maiden career GP3 win with a dominant performance at Silverstone, beating team-mates Giuliano Alesi and Ryan Tveter to the chequered flag.
After finishing in seventh place in Saturday's Feature Race, Piquet lined up in second place on the grid for Sunday's Sprint behind Alesi who started from pole position.
When the lights went out for the 15-lap charge to the flag at Silverstone, Piquet got an early jump on Alesi to take the lead on lap 1 before setting the fastest lap on the second tour of the circuit, breaking DRS range from the second-placed Frenchman.
While Alesi searched for the pace to match his team-mate out in front, Tveter, who secured a career-best fourth place finish one day earlier, moved into the podium positions by overtaking Leonardo Pulcini on lap 5.
Behind the battle at the front, an intense fight was emerging for the final points paying positions, with Jake Hughes battling with Dorian Boccolacci, Nikita Mazepin and Niko Kari in search of a points finish in front of his home crowd – a result that the Briton achieved by claiming eighth.
On lap 15, the chequered flag waved and it was Piquet who stood on the top step of the podium, holding off a late-race charge from Alesi after a Virtual Safety Car on lap 12 temporarily halted proceedings. Tveter finished in third place to complete a 1-2-3 for Trident.
Saturday's Feature Race winner, Anthoine Hubert, finished in fourth place to successfully extend his lead in the Drivers' Championship with rival and team-mate Callum Ilott claiming fifth in the second ART Grand Prix machine.
Leonardo Pulcini was sixth for Campos Racing while Mazepin was seventh. Hughes completed the top eight.
Boccolacci narrowly missed out on a points finish in ninth while Tatiana Calderon put in an impressive performance to finish in tenth place, albeit outside of the points, after starting from 17th, battling her way through the field to secure her best finish of the 2018 season.
Sunday's Silverstone Sprint saw four drivers fail to see the chequered flag, with Julien Falchero, Kari, David Beckmann and Gabriel Aubry retiring.
After beating Ilott on Sunday, Hubert now holds a six-point lead while Piquet has jumped into fifth place in the Drivers' Championship as his impressive rookie campaign in the series continues.
GP3 will return in Hungary for the ninth and 10th rounds of the 2018 season on July 21 and 22.
