Robert Kubica's says he would be able to race "without any limitations", following his return to a Formula 1 cockpit for the first time in six years.
Kubica's F1 career came to a halt in 2011 when he was involved in a rallying accident during the 'off-season', severely injured his right-arm in the crash, forcing him to undergo several rounds of surgery.
It seemed unlikely that he would ever be able to pilot an F1 car again, due to the confined nature of the cockpit and the limited movement in his arm, but following a Renault test a fortnight ago in a Lotus E20, Kubica says there are no issues whatsoever.
"It turns out that [an F1 car] is not as scary as it seemed to be," Kubica told Polish TV network Eleven Sports. "I can even admit that an F1 car was one of the easiest machines to drive with my limitations following my accident.
"Now I can sleep better because I know that I can drive an F1 car without any limitations, I can drive quickly and consistently."

Although there are no plans for a comeback just yet, Kubica says that is ultimately his aim.
Speaking about the recent test, the 32-year-old said he felt at home behind the wheel almost immediately.
"One of the best moments was returning to the pits after my first run when I realised that everything was under control and nothing had changed," he said.
"After the first three laps it seemed that the break had not lasted more than a month. It was a shock as I had a lot of question marks after so many years [away from the sport].
"I have been working on my physical condition. I've never been so fit. For the first time in my life my body weight is lower than in 2008.
"I felt very confident in the cockpit. I felt at home."
