“Day by day, rally by rally and test by test I see fewer limitations and
my goal is one day to drive properly. I don’t think pace will be a problem.

“When I drive it takes concentration and I forget my body’s limitations.
With the damage I have, I cannot (ever) achieve 100 per cent of what I had
before – but I hope to improve.

“If the limited pronation and supination were fixed 80 per cent, I would
say ‘yes’ to coming back to F1.”

Toto Wolff, the new head of motorsport for Mercedes, admitted he would “love”
to see Kubica back in a Formula One car in the future, but conceded that
this week’s test was a step into the unknown.

“We all obviously like Robert,” Wolff said. “He’s very special. I think
what we want to do at Mercedes-Benz is give him a chance of doing a proper
test in a proper racing car, seeing how he goes and how he feels.

“He’s not 100 per cent fit yet. It’s the first time he’s in a car with
downforce and I think we have to take it from there.

“If we see that he is doing well in a proper racing car with downforce, I
think there are still some physical constraints to driving a monocoque
chassis, with his elbow and with his arm.”
