2010 On 29 September 2009, Stefanović announced his plans to compete in the first round of the 2010 season, in Bahrain, despite not having an entry for the 2010 season, and the
Concorde Agreement only allowing for the presence of thirteen teams on the grid. Further opportunities to enter the sport in 2010 arose when manufacturer teams
BMW Sauber and
Toyota withdrew their entries. On 3 March 2010, the FIA announced that USF1 "[would] not be in a position to participate in the 2010 FIA Formula One World Championship" and that it would be impossible to add a new team to the grid less than two weeks before the
opening race of the season. Zoran Stefanović was reported as attempting to merge USF1 with Stefan Grand Prix, though the plan failed after meeting with resistance from USF1 founders
Peter Windsor and
Ken Anderson. The team planned to include a young driver program that would allow rookie drivers testing time on behalf of the teams they sign for; as Stefan would be immune to the ban on in-season testing as it had not been accepted to the 2010 grid. On 29 January the team confirmed that it would be receiving technical support from Toyota, and that it was still pushing in its efforts to join the grid for 2010 just six weeks before
the first race of the season. Despite not having an entry, the team had sent its equipment to the
Bahrain International Circuit in preparation for the
2010 Bahrain Grand Prix. The team also planned to test its car over three days at
Autódromo Internacional do Algarve on February 25–28 with two drivers, but this was cancelled as the team could not secure a tyre supply. Formula One's sole tyre supplier,
Bridgestone, would not supply F1-specification tyres to Stefan until the team acquired an entry. Formula One's commercial rights holder
Bernie Ecclestone mentioned that he had spoken to
Mirko Cvetković, the then-
Prime Minister of Serbia, and that he was confident that Stefan had the funding required for F1. Three weeks later, the team announced that the partnership with
Toyota Motorsport had ended because it was not feasible to continue for an entry for 2010. However, it did not rule out the possibility of the partnership being re-established for 2011. In April, Stefanović announced that in addition to applying to enter the season, he was also planning to build the "Stefan Technology Park", which included a Formula One-standard circuit, in
Stara Pazova.
2011 Following the withdrawal of USF1 from the 2010 season, the FIA announced that it would re-open the selection process for
2011. In the week before the
2010 Italian Grand Prix, the FIA announced that none of the prospective entrants met the minimum funding or engineering requirements, leaving the thirteenth grid slot vacant.
2015 The bid process was not re-opened for the
2012 season. In March 2014, it was revealed that Stefanović had again lodged an application to join the Formula One grid after the FIA had announced earlier that the entry process would be reopened with the intent of new team joining the grid starting with the
2015 Formula One season. Stefanović withdrew the application in February 2014.
2019 In July 2017, Stefanović revealed a new plan to enter the series from the 2019 season, stating that he had a facility in
Parma and personnel ready to set up a team. The statement of intent came two weeks after rumours surrounding the entry of a Chinese team for the 2019 season became public. ==Car and drivers==
