Kubica quiet on future

Robert Kubica is refusing to speculate on his future in the wake of Mercedes' confirmation that he will test one of their DTM cars on Thursday.

Kubica's Formula One career was put on hold after he sustained serious injuries in an horrific rallying accident almost two years ago.

The 28-year-old Pole, who has undergone several operations, has since taken part in a number of national rallies as part of his lengthy rehabilitation.

Kubica will take another vital step towards a potential comeback tomorrow when he gets behind the wheel of one of Mercedes' German touring cars, the AMG C-Coupe at the Ricardo Tormo Circuit in Valencia.

For Kubica, it will be his first proper outing on a racetrack under test conditions since his time in Formula One.

"I'm really pleased Mercedes-Benz is giving me the opportunity to test their car, and I'm looking forward to getting acclimatised to a race car again," said Kubica, who suffered a partially severed right hand in addition to elbow, shoulder and leg fractures in the accident on the Ronde di Andora rally on February 6, 2011.

"It will be in proper testing conditions, on a permanent circuit, and it's important because the car has good levels of downforce.

"But it's still too early to make any statements about my future because of this one test. I'm just looking forward to tomorrow and we'll see what happens after that."

Prior to his accident, Kubica competed in 76 grands prix for BMW Sauber and Renault, with his sole victory to date coming in Canada in 2008.
