A realistic Robert Kubica admits he still has a long way to go to recover from injuries he suffered in a rally crash in 2011.
The Pole endured significant injuries in February that year when he crashed his Skoda Fabia into a barrier in the first stage of the Ronde di Andorra, an incident which forced doctors to rebuild his right hand.
After feeling his way back into racing by focusing his comeback around rally cars, Kubica made a long-awaited return to the cockpit of a race car when he took the wheel of a DTM Mercedes in Valencia last week.
While revealing his condition is improving with every drive, the former BMW Sauber and Renault driver stressed he is some way from a full return to competitive track racing.
"I have big injuries, so there is still a long way to go for my health and my body," Kubica told the DTM's online TV channel.
"But yeah, slowly it is getting better. Of course, it has needed time.
"This test was just to get a feeling of the car and see how it looks and how it is to drive a DTM car.
"Overall I feel comfortable in the car which is good. That is always important, especially if you only have a short time to adapt."
Currently, Kubica cannot drive a single-seater racer due the condition of his right arm but he has not given up on one day returning to Formula One, telling F1 Racing magazine last week that a comeback is 'more than just a dream'.
For now however, the 28-year-old is just happy to be able to drive track cars once again and after testing the DTM car said he would be open to competing in the category.
"If I have enough room in the car - and in the DTM car I do - then there is no big limitation for my arm," he said.
"So we will see. For sure, the DTM can be an option for me."
