Kerb loading led to the incident that Perez suffered in FP1 yesterday


It has been announced today that the wishbone failure on Sergio Perez’s Formula 1 car that led to his Hungarian Grand Prix practice crash was caused by repeatedly using the full length of the track’s kerbs.

The Mexican’s Force India was heavily damaged when it hit the barrier before rebounding and rolling after the right-front wheel folded under the front of the car.

The accident was triggered by a failure caused by the high loading experienced at the Hungaroring.

In an interview with the media today, Force India chief operating officer Otmar Szafnauer stated the following:-

‘The failure was due to the fact the loading that it saw is different to any other track on the calendar.

‘The rumble strips here are so long that if you ride on them completely, you get high frequency, a decent aptitude load, that you don’t see anywhere else.

“You can still run onto them, but don’t stay on them forever. But, we have stiffened them up significantly after testing them back at base.’

The design philosophy of the B-spec wishbone is the same as its predecessor but the team had to make new parts for the updated car so that it would fit.

Force India had brought a new floor and front wing to this race, but as there was a quick turnaround between races, the team had no spares and thus Perez was forced to return to the original B-spec car debuted at Silverstone for the rest of the weekend as a result of this.
