Rally Bulgaria (Рали България) is the most prestigious and also the oldest rally event in Republic of Bulgaria.
 It was confirmed for the 2010 World Rally Championship season as the seventh of all thirteen planned events.
 Year 2010 was also the first and so far the only one that Rally Bulgaria has been in the World Rally Championship, having previously hosted races for the European Rally Championship instead.
 The application of the country was accepted by the FIA despite the fact that Rally Bulgaria's candidate event in July 2009 ended in an accident which killed Italian co-driver Flavio Guglielmini and seriously injured Swiss driver Brian Lavio.
 Bulgaria was the only new candidate for the 2010 World Rally Championship season, although Rally Argentina had made a reserve application just in case Bulgarian rally failed.
The 2010 Rally Sweden was the opening round of the 2010 World Rally Championship season.
 It was the season's first and only event held on snow- and ice-covered gravel roads.
 The rally was held over February 11–14, beginning with a Super Special Stage in the event's base town of Karlstad.
 The rally was also the first round of both the Production Car World Rally Championship, and the brand-new Super 2000 World Rally Championship.
The 2017 Rally Sweden (formally known as the 65th Rally Sweden) was a motor racing event for rally cars that was held over three days between 10 and 12 February 2017.
 It marked the sixty-fifth running of the Rally Sweden, and was the second round of the 2017 World Rally Championship and the WRC-2 and WRC-3 championships.
The 2017 FIA World Rally Championship is the forty-fourth season of the World Rally Championship, an auto racing championship recognised by the Fédération Internationale de l'Automobile (FIA) as the highest class of international rallying.
 Teams and crews are competing in thirteen events—starting in Monte Carlo on 19 January and ending in Australia on 19 November—for the World Rally Championships for Drivers, Co-drivers and Manufacturers.
 Drivers are free to compete in cars complying with World Rally Car and Group R regulations; however, only Manufacturers competing with 2017-specification World Rally Cars are eligible to score points in the Manufacturers' championship.
 The series is once again supported by the WRC-2 and WRC-3 championships and the newly created WRC Trophy at every round, and by the Junior World Rally Championship at selected rounds.
The 2018 FIA World Rally Championship will be the forty-fifth season of the World Rally Championship, an auto racing championship recognised by the Fédération Internationale de l'Automobile (FIA) as the highest class of international rallying.
 Teams and crews will compete in fourteen events for the World Rally Championships for Drivers, Co-drivers and Manufacturers.

The FIA World Rally Championship-3, or WRC-3 (formerly known as Production World Rally Championship, or PWRC), is a companion rally series to the World Rally Championship, and is driven on the same stages.
 WRC-3 is limited to production-based cars homologated under the R1, R2 and R3 rules.
 The series began in 2002, replacing the FIA Group N Rally Championship and it was for Group N cars.
 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.
The Rally of Poland (in Polish, "Rajd Polski") is a motorsport event for rally cars that was first established in 1921.
 It is second-oldest rally in the world, preceded only by Monte Carlo Rally.
 In 1973, the Rally of Poland was the one of the thirtern rounds of newly established FIA World Rally Championship, but was removed from the 1974 calendar.
 It later found a place as a round of the European Rally Championship, and after a move to Mikołajki in the Masurian Lake District in 2005, event organisers started lobbying for the event's inclusion as a round of the World Rally Championship.
 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.
 However, the event was once again removed after a single season, and was replaced by Rally Bulgaria.
The FIA World Rally Championship-2 or WRC-2 (formerly known as Super 2000 World Rally Championship or S-WRC), is a companion rally series to the World Rally Championship, and is driven on the same stages.
 WRC-2 is limited to production-based cars homologated under the Super 2000, N4, R5 rules.
 The series began in 2010 and split the Production World Rally Championship (P-WRC), which was previously open to both Super 2000 and Group N4 cars, into two separate competitions, both of which received their own FIA titles.
 There was also a World Rally Championship Cup for Teams within the S-WRC but this was discontiniued after 2010.
