Williams' Lowe has 'no issues' with Kubica fitness
Paddy Lowe says Williams are convinced Robert Kubica is fit enough to race in Formula One after he completed another testing session in Abu Dhabi.
The Pole was an assured presence behind the wheel at Yas Marina circuit, as he attempts to secure a return to F1 following a serious rally crash in 2011, and managed to go quicker on Pirelli's new hypersoft tyres than Williams driver Lance Stroll.
It remains to be seen if the former Renault driver has done enough to earn a seat in 2018, but Williams' chief technical officer has been impressed.
Asked if Kubica has proven his readiness, Lowe said: "Yes, there are no issues around that subject. Robert did a great job.
"We were very happy with that, absolutely with the number of laps and with the running altogether.
"[His feedback is] very good. He is a driver of tremendous experience and very knowledgeable around his work.
"His job is a professional racing driver so he has that confidence and you can feel it in the garage so everybody's happy with Robert."
According to Lowe, Kubica's determination to recover from the major injuries he suffered has won the 32-year-old plenty of fans.
"Robert is a driver that we've all admired when he drove in Formula One and even since then," he said.
"It's a great example of his character that he considered coming back from this accident that he had and fighting away just seeking if he could come back into Formula One."
As for selecting Williams' next driver line-up, Lowe said: "We'll keep working.
"We're concentrating on the testing and then we'll regroup afterwards to make our decision for next year in terms of racing."
