Luca Filippi will test the 2012 DTM title-winning BMW at the Estoril circuit, the Italian said on Friday.
Filippi was without a full-time seat for the 2012 season after finishing as runner-up to Romain Grosjean in the 2011 GP2 championship. The 27-year-old made a sensational return to the series this year with Coloni at Monza, where he took victory despite not having raced for several months.
Filippi is still chasing a seat for next year and will get behind the wheel BMW M3 with which Bruno Spengler took the title in the German manufacturer's return to the series.
The test will take place at the Portuguese circuit next week.
