Nov.27 (GMM) Pedro de la Rosa has admitted he left Brazil after Sunday's 2012 finale with a real sadness.
HRT's owner Thesan Capital is no longer prepared to fund the Spanish backmarkers, making it likely Interlagos was the last race in the team's three-year history.
"We have finished the season with so much uncertainty about what will happen now," lead driver de la Rosa told Antena 3 television.
"We started the project thinking it would be long term," he said.
At the very least, de la Rosa acknowledged that Formula One will no longer have a Spanish team.
"Whatever happens, for many reasons, the team will not be Spanish and that's the biggest sadness I have," he said.
"We will probably never see a Spanish team in Formula One again."
