Ralph Boschung has revealed that he believes he could have finished in the top-five in the Drivers’ Championship in last year’s GP3 season had he completed the full campaign.

Boschung is one of five drivers from the 2016 season to graduate to Formula 2 in 2017, joining Alexander Albon, Nyck de Vries, Antonio Fuoco and champion Charles Leclerc, after signing for Campos Racing.

The Swiss racer missed three of the final four rounds in Belgium, Malaysia and Abu Dhabi after his best start of a season, claiming a maiden win in the Austrian sprint race last July with Koiranen GP.

He finished 11th in the championship with 48 points, the second-highest Koiranen driver in the standings. Boschung believes that if he had been able to continue, he could have returned to the top step of the podium later in the year.

“As a team at Koiranen we showed that we were capable of race wins and consistent top-five positions,” he told Read Motorsport.

“The level of the championship was obviously very high, but realistically if we would have kept the momentum from Austria, Silverstone and Hungary, we could have fought for more race wins and probably a top-five or top-six in the championship at the end of the year.”

Despite not being able to finish the year, he is still grateful for the skills he has learned during his 18-month spell in the series.

“Last year was obviously quite a short year for me, but accumulating one-and-a-half years of GP3 has massively helped me develop as a driver in many areas I never thought I could improve on.”

He also praised the efforts of his former staff at the Finnish team.

“It’s a team that with limited resources compared to ART Grand Prix still were able to fight for championships and race wins.

“The engineers we had were on top of the game every time, and my team-mates Matt Parry and Matevos Isaakyan were really pushing the team in the right direction. I definitely had great experiences and learned a lot.”
