The 2017 World Rally Championship-2 is the fifth season of the World Rally Championship-2, an auto racing championship recognized by the Fédération Internationale de l'Automobile, running in support of the World Rally Championship. It was created when the Group R class of rally car was introduced in 2013. The Championship is open to cars complying with R4, R5, and Super 2000 regulations.Esapekka Lappi did not return to defend his 2016 title as left Škoda Motorsport for the top WRC category to become third driver of Toyota GAZOO Racing.
The season is being contested over thirteen rounds in Europe, North and South America and Australia.
The FIA re-organised the calendar for the 2017 season to include a greater variation in surfaces between events, bringing the Tour de Corse forward from October to April. The decision was made after concerns were expressed about the 2016 calendar, which originally contained six consecutive gravel events followed by four tarmac rallies.
The Rally of China was removed from the calendar. The event had been included on the 2016 calendar before storm damage to the proposed route forced its cancellation. The round was removed from the 2017 calendar to give event organisers more time to prepare for a future bid to rejoin the calendar. Similarly, the FIA put the Rallies of Argentina and Poland on notice regarding safety concerns, threatening to rescind their World Championship status for the 2017 season unless safety standards were improved in 2016, with drivers citing a lack of safety marshalls and expressing concerns over spectators getting too close to the cars as the main areas to be addressed. Both events were subsequently included on the calendar.
