Anyone who hadn't spotted ?scar Tunjo's graduation from Formula Renault 3.5 Series to GP3 over the winter will certainly have had their attention firmly captured by his race performance on Sunday morning in Austria, when he managed to leave his rivals standing with a superb display of overtaking that propelled him all the way from ninth place on the grid to the top step of the podium just 26 minutes later.

Tunjo had missed out on gaining any advantage from the reverse grid rules that had put Jenzer Motorsport's Ralph Boschung in pole position alongside Status Grand Prix's Sandy Stuvik for the green flag to Sunday morning's 18-lap race 2 in dry, bright and sunny conditions at the Red Bull Ring. The field had been trimmed to just 23 cars after Arden was forced to withdraw Kevin Ceccon's #14 car overnight after it was too badly damaged in a starting grid accident on Saturday. By contrast, Carlin had managed to patch up Mitchell Gilbert's car to allow him to take his place at the back of the grid after being involved in the same crash, and Campos Racing's Samin G?mez was also back in the fray despite suffering a sprained wrist when she had been wiped out as the innocent bystander to the incident.

When the lights went out it was Boschung who narrowly held on to the lead going into turn 1 ahead of a fast-starting Marvin Kirchh?fer in the ART, with Stuvik left desperately fighting off Jann Mardenborough down the long run into turn 2. Running behind them, Saturday's star racer Antonio Fuoco misjudged his braking into the right hander and ran straight into the right rear of his Carlin team mate. He was launched into the air by the impact, crashing down on the front of Stuvik's Status. Also out of the race were ?lex Palou (Campos Racing) and Alfonso Celis Jr (ART Grand Prix) as a result of a clash in the first corner, while P?l Varhaug hadn't even made it that far after being forced to pull into pit road at the end of the formation lap with a technical issue on his Jenzer Motorsport.

After three laps behind the safety car for a clean-up, the racing resumed fast and furious with Marvin Kirchh?fer (ART Grand Prix) getting the better of Boschung in turn 2 for the race lead, and Esteban Ocon (ART Grand Prix) similarly getting the better of Emil Bernstorff (Arden International) for third place, which he quickly upgraded to second with a nice move on the struggling Boschung next time by.

Saturday race winner Luca Ghiotto (Trident) was also on the march, the next to quickly dispatch Boschung enabling him to put one foot on the podium. It took Bernstorff until the midpoint of the race before he too found his way past the Swiss teen, which opened the door for Tunjo to follow him through and drop Boschung to sixth place ahead of Seb Morris (Status Grand Prix) who had managed to climb up to seventh place over the opening laps having started far down the grid from 19th position after incurring a pit lane speeding penalty on Saturday. Unsurprisingly it was only a matter of minutes before Morris too was putting the pole sitter in his rear view mirror.

With less than six laps remaining, it was now Tunjo's turn to burst into life. The 19-year-old Colombian kicked things off with quick, decisive passes on both Bernstorff and Ghiotto to force his way onto the podium, which he then followed up with a lovely smooth move on Ocon to take second spot. Nor was that looking the end of his run, as race leader Kirchh?fer was less than a second down the road having been unable to pull out a sizeable safety margin at the front since passing Boschung at the restart.

Kirchh?fer's tyres looked in a bad state, and this played out with a devastatingly easy pass around the outside for Tunjo to take the lead of the race with three laps remaining. A lap later he was already 1.4s clear of the field and it was evident that no one would be able to carry the fight to him in the time remaining. When the chequered flag came out his lead has stretched to a full three seconds as he celebrated his maiden win and first podium in only his second weekend in the GP3 Series.

Kirchh?fer had just enough life left in his tyres to cling on for second place by a narrow margin over Ocon, while Ghiotto had to settle for fourth place on this occasion having survived a late challenge from Bernstorff on the penultimate lap which saw him elbow the Arden on to the run-off area. Bernstorff showed brilliant car control to gather up the pieces and not crash as a result, and was rewarded with fifth place ahead of Jenzer Motorsport's Math?o Tuscher who got the better of Seb Morris as the Briton paid for his early flying laps with degraded pace toward the end. Status Grand Prix's Alex Fontana picked up the final point available in eighth place ahead of Matt Parry (Koiranen GP) with Ralph Boschung ending his long morning's descent down the running order in tenth place.

Further back Gilbert ended the day in 13th place in his repaired piecework Carlin, two spots ahead of his team mate Mardenborough who had been the sole survivor of the two lap 1 incidents after being able to continue following a visit to pit lane for running repairs. Samin G?mez also needed an unscheduled pit stop during the race and ended up finishing in last place, a lap off the leaders.

In the championship standings, this weekend's work in Spielberg, Austria means that Ghiotto emerges with the lead of the drivers' championship by ten points over Ocon, followed by Kirchh?fer and Bernstorff.

However it's very early days, with only two rounds of the nine-round season complete. The next action for the GP3 drivers and their team will come from Silverstone on July 3-5.
