Jani chooses A1GP over Champ Car

The 24-year-old Team Switzerland driver is one of the favourites to win the A1 title and says he would rather concentrate on that than race in America this summer.

He told autosport.com: "The pre-season Champ Car tests clash with A1 races and when I look at how well we're going in A1, why would I want to not race to go and test a Champ Car?

"Champ Car has a very uncertain future and I haven't had an offer that I think I could win the title with, so why would I give away a title chance in A1 for that?"

Jani believes A1GP has developed into a championship that drivers can contest without racing during the summer as well: "You can do this and nothing else. Formula One drivers don't have to look to do anything in the winter and it's no different for us.

"I don't have to bring a budget to A1, the racing is good, and it gets excellent coverage. Most people would like to have a go at F1 as well of course, and that's my target as well, but a driver doesn't have to look beyond A1 - you could stay here for your career."

The Swiss is hoping to line up some F1 testing this summer and is chasing a race drive for 2009.
