Simona de Silvestro's road to Formula 1 appears to have ended.
Until now, the 25-year-old female Swiss driver was a Sauber tester, testing one of the Hinwil based team's older cars with unique 'Clean Air Energy' branding.
The former IndyCar driver had also been linked with a F1 debut in Friday morning practice in Austin next month..
However, her F1 career hangs in the balance after negotiations to resolve a contractual dispute between her management and the Sauber team broke down
"Simona's driving programme will not continue for financial reasons on her side," a spokesman for the Swiss team confirmed.
"Everyone who has worked with Simona over the past six months is very disappointed.
"We are currently examining other possibilities," the spokesman is quoted as saying.
British magazine Autosport understands she will retain her status as an affiliated driver.
