The World Touring Car Championship has switched its season-opening round back to Curitiba.
The March 19-20 event had been due to take place at Interlagos, but that plan has now been abandoned due to logistical issues owing to renovation work being done at the Brazilian Grand Prix venue.
WTCC promoter Marcello Lotti said that the event would, as planned, share top billing with the country's hugely popular V8 Stock Car Championship.
"After five years as a standalone event, WTCC is now facing an important development through this partnership with [Stock Car promoter] Vicar [Promocoes Desportivas]," he said.
"The opportunity of sharing the event with V8 Stock Cars and the outstanding joint promotion set up by Vicar will greatly enhance the world championship's popularity in Brazil. I wish to take this opportunity to thank the Municipality of Curitiba that enthusiastically keeps on supporting the WTCC event in Brazil."
Lotti also announced that Vicar will promote the event for the next three years, meaning that it is likely to feature both championships until at least 2013.
