Ralf Schumacher looks set to call time on his Formula One career after a poor test drive for Force India, according to reports in the German press on Friday.
Schumacher has been out of contract since October when his Toyota contract expired and has struggled to find another team after the worst season in his 11-year career left him 16th in the World Drivers Championship.
"It looks like that was the last time I will drive a Formula One car," the 32-year-old younger brother of seven-times world champion Michael told German tabloid Bild on Friday.
"It is not expected that I join Force India, I took on the test drive as an opportunity to prove myself."
After the test drive in Spain, Schumacher was 20th and last of all the test drivers, nearly three seconds behind leader BMW driver Robert Kubica.
Force India, formerly known as Spyker, had been seen as a potential employer for Schumacher after spells with Jordan (1997-98), Williams (1999-2004) and Toyota (2005-07).
"I would like to continue my career in F1, but it is not an obligation. I would like to continue, but I don't know if these are the right conditions," he added on television channel RTL.
Ralf Schumacher has already offered his services at McLaren-Mercedes to succeed Spaniard Fernando Alonso and has been told they will make a decision on who will partner Lewis Hamilton in January.
