Austria's Patrick Friesacher has been named as Minardi's second race driver for the forthcoming Formula One season.
The 24-year-old will join Dutchman Christijan Albers on the grid for the first race in Melbourne on March 6.
Friesacher, who has won two races in Formula 3000, said: "For me, it is the realisation of a long-held dream to be in F1. I am extremely happy."
Minardi had been expected to sign Denmark's Nicolas Kiesa, but a funding problem opened the door for Friesacher.
Minardi boss Paul Stoddart was impressed by the Austrian in testing last November.
"He's a quick and, equally importantly, consistent driver, who is also capable of providing good technical feedback to the engineers.
"I firmly believe the combination of Patrick and Christijan Albers, will provide Minardi with an extremely strong young driver line-up this season, " he added.
