Jul.27 (GMM/Inautonews.com) Fingers were being pointed at the Hungaroring’s curbs after Force India suffered a second failure of the weekend with its new ‘B’-spec car.

The Silverstone based team was buoyed by the early promise of the heavily modified machine, until Sergio Perez suffered his spectacular roll-over shunt in Friday practice.

As a precaution, teammate Hulkenberg then also sat out the second session while the apparent suspension problem was investigated.

Then on Sunday, it was German Hulkenberg’s turn to have a terrifying crash when the front wing folded underneath his car, spearing him into the barriers at full speed.

Force India technical boss Andy Green furrowed his brow.

“It was the same wing design as in Silverstone,” he told Germany’s Auto Motor und Sport. “The wing itself was brand new.

“But if it was ok at Silverstone then it should also have been ok here.”

Green acknowledged that it had been a structural failure, but fingers were also being pointed at the Hungaroring’s curbs.

“They are the most aggressive on the whole calendar,” said Hulkenberg.

Officially, Force India is still investigating, but it is true that Ferrari also had a front wing failure in practice.

The FIA’s Charlie Whiting insisted: “The curbs have not changed since last year.”
