Robert Kubica insists he won't head to DTM or another touring car series any time soon as his focus is still on Formula One.
The Polish driver has been away from F1 since partially severing his right forearm in a rally crash back in February 2011.
But while the closest he has come since to a F1 car was a recent run in the Mercedes F1 simulator, the 28-year-old was offered a DTM drive with Merc for this year's Championship.
Kubica turned it down, opting instead to contest the European Rally Championship.
And the former Renault driver says he will keep saying no as long as Formula One is still a possibility.
"For me, now, the priority is to get as fit as I can," he told Autosport.
"I'm not able to come back into single-seaters at the moment, and my vision is not to come back in saloon cars on the circuit at this stage.
"DTM, for me, is one of the highest-level Championships in the world, the drivers who are racing there; I'd say there's a minimum of 10 who can win races. It's a very high-level Championship.
"It's not that I'm underrating these cars, or GTs or anything else, it's just that I have something in my mind and I'm trying everything to achieve it, and this is the best way for me.
"Maybe one day in the future I will race in DTM or GT or whatever, because I will feel that it's the right moment. I'm still young, I think I can still achieve something in motorsport, I will try my best."
Kubica, though, admits that a future in Formula One may never be on the cards.
"There is not any guarantee, there is no percentage to say whether I will come back or not, but it's also not 100 per cent that I will not be back in F1. I will try my best.
"I have been through a difficult period, and I'd say it's an easier period now, I am enjoying myself, but it is still not a totally easy period for me, because I'd definitely prefer to be in F1 driving, 100 per cent fit. The reality is different.
"Now I need a little bit of everything - a little bit of luck and motivation, which I think I have, and to keep working so maybe I have the chance to get back to where I was before the accident."
