Luis Perez-Sala has reportedly joined HRT as an official advisor to the Spanish team's new owners Thesan Capital.
The former Minardi driver was with the team at Silverstone two weeks ago and reportedly carried out an initial analysis in which it was decided the 'Hispania' moniker would for example no longer be used.
"Sporting competition is quite alien to Thesan so they need the advice of an expert," said the daily Spanish sports newspaper AS.
52-year-old Sala, who raced in F1 with Minardi in the late 80s, reportedly had existing links with the Spanish bank Banco Popular, which was involved in the sale of HRT to Thesan.
AS said Sala will make his next appearance at a Grand Prix in Hungary next weekend.
