Sergio Perez has escaped injury after a spectacular crash during opening Formula 1 free practice for the Hungarian Grand Prix.
With just 30 minutes of the session remaining, the Force India driver ran across the artificial grass on the exit of Turn 11.
Television footage of the crash indicated that there was a failure at the right rear of his car – most likely in the suspension – which pitched his car in to a spin.
Perez spun across the track and, after swiping the barriers on the right hand side of the track, his car flipped over its front tyre before ending up upside down.
Perez was able to get out of the car with the assistance from a track official and early indications are that he has suffered no injuries.
"It was a really bad accident, pretty unlucky," said Perez. "The track was dirty and I went on the AstroTurf and I collided [with the barrier] on the other side of the track at a very bad angle, so it made the car roll over.
"But everything's alright. It was a strange accident. I thought it was under control but the AstroTurf was very dirty which is why I went in the wall. We'll have to check everything in detail."
The session was red-flagged immediately while the wreckage of the Force India was returned to the pits.
