Adriano Buzaid took his third Silverstone victory of the season the second Formula Renault UK Championship race of the weekend at Silverstone.
Fortec Motorsport's Brazilian driver, who now has a total of four wins this season, added victory on the National circuit to his double triumph on the Grand Prix circuit at World Series by Renault. Alpine Motorsport's Dean Stoneman took second, while Manor Competition's Henry Surtees was third having started 15th on the grid.
CR Scuderia Formula Renault's championship leader Adam Christodoulou retired on lap one after contact with pole-sitter Jordan Oakes. Manor's Alexander Sims came fourth to close the gap at the top of the drivers' standings to 34 points after dropped scores are taken into account, the equivalent of a race win plus fastest lap bonus.
Alpine Motorsport's Dean Stoneman has now won the Graduate Cup category, for young and inexperienced drivers, with two races to spare. He follows Adam Christodoulou as winner of the rookie competition.
A damp track greeted the drivers for the 18th round of the single-seater series and ever-changing track conditions would play a role in the ensuing 22-lap race. Eurotek Motorsport's Oakes made a clean start from pole position but Christodoulou was able to draw alongside on the run to Copse. Oakes ran onto the tarmac run-off area as Christodoulou took the inside line, but the pair clashed wheels as Oakes rejoined the circuit. While he continued, Christodoulou spun and was then unable to turn into Becketts due to damaged suspension.
Starting fourth on the grid, Sims spun as he took avoiding action exiting Copse, while CR Scuderia's Ryuji Yamamoto surged from the fifth row to challenge the leaders. Stoneman led through Becketts but Oakes re-passed him at Brooklands before Buzaid took the lead with great traction out of Woodcote as Yamamoto followed in second.
Further contact in the midfield saw CR Scuderia's Jesse Krohn lose his front wing after hitting Fortec Motorsport's Riki Christodoulou, who suffered a broken rear wing. Both continued in the race, eventually finishing twelfth and 14th respectively. Meanwhile, from 17th on the grid, Apotex Scorpio Motorsport's Josh Scott reached ninth place by the end of lap one.
After a brief Safety Car spell, Stoneman immediately took third place from Oakes at Becketts, the pole-sitter then spinning at Brooklands as he tried to regain the place. Two laps later, Stoneman got a great run out of Becketts and passed Yamamoto at the end of the National Straight.
Krohn's lack of front downforce allowed Alpine Motorsport's Rossi and Fortec's James Calado to pass. Lap eight saw Sims, recovering from almost last on the road, reach 11th place by passing Fortec's Oli Webb as they crossed the start/finish line. One lap later, he overtook CR Scuderia's Scott Jenkins.
