Federico Montoya, the younger brother of Williams driver Juan Pablo, will drive in the German Formula BMW series next year.
The Berlin-based Muecke team said on Monday that the 19-year-old would drive for them in 2004.
"He is a great talent and will go places in motor racing," team chief Peter Muecke said of the Colombian, who had a promising run in the Florida Easykart series this year.
The most famous siblings in motor racing are Ferrari's world champion Michael Schumacher and younger brother Ralf, who is Montoya's team mate in the BMW-powered Williams team.
