The lowdown on F1's prospective 13th team

Pre-season testing for 2011 is under five months away and the F1 community is still none the wiser as to who will be filling the vacant 13th team slot. Reports suggest a total of 15 teams - the same number of applicants as last year - applied to enter Formula One, but with main favourite ART Grand Prix having withdrawn their entry recently, among others, it leaves just three potential contenders vying for the coveted grid slots.
