Anthony DavidsonAnthony Davidson could make a racing comeback in the DTM this season after testing for Audi in Spain earlier this week. Audi has at least one vacancy in its lineup following the retirement of Tom Kristensen, and Davidson says the series appeals to him.

"I would definitely be interested in racing in the DTM; it's something I've got my eye on," he told AUTOSPORT. "If I was given a chance to do it, I would. They invited me to come and do the test and you can't turn down a company like Audi."

The former Super Aguri Formula 1 driver, who was contracted to the Brawn squad until the end of last year, admitted that he is starting to evaluate his options outside of F1 after spending 18 months on the sidelines since the withdrawal of Honda's second team in 2008.

"I've tried very hard to get back into F1, and I'm still trying," said Davidson, "but with the chances of finding something diminishing there I've decided to look at opportunities elsewhere. I've always wanted to drive a DTM car, so this has been a good experience."

Davidson was joined at the Audi test by Formula 3 drivers Mika Maki and Jean-Karl Vernay, Porsche racers Rene Rast and Jan Seyffarth, former A1GP driver Filipe Albuquerque, and Formula Renault 3.5 regular Miguel Molina.
