The World Rally Championship is set to welcome another factory team in the form of Volkswagen, who will join the likes of mainstays Citroen and Ford, as well as newcomers MINI. It has been reported that VW will confirm its WRC entry on May 5 at a press conference in Sardinia, the eve of Rally d’Italia.

There’s no official quote, but apparently the agreement was reported to have just received the final internal signature required. Some have said that VW initially planned to reveal its WRC intentions in Portugal last month, but lacked those all important signatures.

Rumours are that the Italian announcement will include details of a “Polo World Rally Car” that will contest selected WRC rounds in 2012 before doing a full season in 2013. Driver speculations include the names of ex-champ Petter Solberg and Nasser Al-Attiyah, the Qatari who won this year’s Dakar Rally with VW.
