Rubens Barrichello suffered a disappointing Turkish Grand Prix on Sunday at Istanbul Park and in the end his race was compromised by a series of mechanical issues.
Barrichello had qualified 15th, but he had a very poor start and a problem with the Grove-based outfits anti-stall system immediately cost him five places and dropped him down to 20th.
Although he then pushed hard throughout the race and battled his way back to 14th, he was further delayed by a slow pit stop and an issue with the throttle.
“I had a problem with the clutch at the start which is a shame because it's been fine all weekend so we will have to investigate that,” Barrichello stated. “We pitted earlier than we had originally planned because our pace was better than the cars in front.
“Our stop was quite slow because we had a problem with the front wheel. Later on, I then had an issue with the throttle. Our overall race pace wasn't too bad but we need to resolve these issues that we are having.”
Team-mate Nico Hulkenberg
also didn't do very well and he picked up a front puncture on the opening lap after contact with Sebastien Buemi. That incident dropped him to 23rd. Hulkenberg eventually finished in 17th.
“It hasn't been a good weekend for us and our race pace wasn't good enough today,” Hulkenberg noted. “I also had an incident on the first lap which meant I had to pit early. We have to keep working hard to find more performance.”
Williams technical director, Sam Michael summed-up: "We finished roughly where we qualified today. Rubens had a problem with anti-stall off the start, it wasn't a driver issue. Shortly after his pitstop, he then had a throttle control problem which dropped him back down the order again. The problem reduced so he was able to continue the race, but we'll be stripping the car down to identify what caused it.
"Nico came together with another car on the opening lap which damaged his front wheel. That forced him into a premature pitstop, so the rest of his race was consumed with tyre management.
"For the forthcoming events, our objective will be achieving better qualifying and race performance."
