Robert Kubica has claimed that he can return to Formula 1 in the future, nearly two years after a crash in a rally car caused him to suffer several fractures to his arm and leg.
The former BMW driver has begun racing in rally cars once again but admits that his biggest target is to secure a seat for a Formula 1 team.
"I still believe I can come back," Kubica told F1 Racing. "It's not just a dream. Right now I have limitations with driving single-seaters, but they are less than they look from the outside.
"Things are improving. It wasn't like this six months ago and it wasn't like this three months ago. And thanks to rallies and tests on the race track, slowly my condition is improving - but there's still a long way to go.
"Most important for me is that I have seen the pace is still there and I am absolutely sure I can drive competitively again."
Kubica has not raced in Formula 1 since the Abu Dhabi Grand Prix in 2010.
