May 17 (GMM) NASCAR driver Kyle Busch has revealed that he is currently in talks to test a formula one car for the first time over the European winter period.

The 23-year-old, who was the Nextel Cup rookie of the year in 2005 and is the current championship leader, also refused to rule out making a full switch to the premier class of open wheeler racing some time in the future.

Busch, who has so far won two races in 2008 with his Toyota Camry, told reporters at the Charlotte track in North Carolina that the first step is talks with Toyota about a formula one demonstration drive in Japan.

"We're working on a test session right now at the end of November or beginning of December sometime -- going to Japan and doing a little exhibition sort of deal and see what it's like," he is quoted as saying by the Speed TV website.

Busch also indicated he would be interested in opportunities to race in formula one.

"I wouldn't mind it," the American said, albeit admitting some misgivings about F1's actual wheel to wheel action that apparently "isn't all that great".

"If I can do it and I'm good at it then I'll give it a shot and try it.

"We'll see how good I test, first.

"We'll see if my neck can withstand the g-forces of the braking and everything," he said.
