After being run as a candidate event in 2007 and 2008, Poland returned to the World Rally Championship in 2009, which was won by Mikko Hirvonen.

The cars used were modified road cars, often based on turbocharged, four wheel drive versions of standard small cars such as the Subaru Impreza WRX and the Mitsubishi Lancer Evolution, although a wide range of vehicles are homologated by the FIA for use in Group N. Apart from FIA sanctioned events, a lot of rallies at national levels are run under Group N.
