Citroen driver Robert Kubica has admitted he would "give all his money" to return to Formula 1 racing.
Kubica has been out of grand prix racing since his rally crash in February of 2011.
The Pole announced details of his first full season of rallying in Warsaw yesterday, revealing a four-round European Rally Championship effort, but he says his focus remains on getting back to F1.
He revealed he turned down the chance to race in the DTM because he knew rallying would provide a bigger physical challenge to him.
Kubica reckons he is ready to race in Formula 1 at circuits like Barcelona, but feels he would not be able to compete at more twisty tracks.
"I would pay all the money I have to be back in the cockpit of a Formula 1 car," said Kubica. "At the moment [racing at] Barcelona would be possible, Monaco would not be possible.
"I would prefer to still be an F1 driver, but if I really saw myself one and a half years ago, and somebody told me I would be announcing a big programme with [ERC sponsor] Lotos, Citroen and Michelin in the European Rally Championship and in the WRC, I would not have believed it.
"I still hope to come back to where I was. I think everybody would like to see me there.
"It's a bit strange, even some people from rallying would prefer I stay in rallying, but I'm coming from Formula 1 and suddenly what was all my life stopped in one second.
"Now I know, I knew it always, but now I appreciate more that there's nothing better in life than doing what you want to do."
Kubica tested a Mercedes DTM car earlier this year before committing to the ERC and WRC2 with Citroen.
If Citroen's planned WTCC programme for 2014 is signed off, it is expected Kubica will play a part in the testing programme, but for now he says that's all he's interested in from the series.
"DTM was a good opportunity for me," he said. "But somehow my way of looking [at] what I want this year... I think is the best for me led me to decide for rallying. I would definitely have an easier life [in the DTM] and better chances of good results, but for me results are not the numbers.
"For me what I am looking for this year is to improve my physical state, improve me as a driver and I hope I will learn a lot of new things thanks to the rallying. Maybe this will be the key for the future."
