2018 World Touring Car Cup

The 2018 FIA World Touring Car Cup (known as the FIA WTCR presented by Oscaro for sponsorship reasons) was the inaugural season of the World Touring Car Cup (WTCR). It took over from the World Touring Car Championship and adopted the TCR technical regulations. It was also the 14th overall season of the series that dates from the 2005 World Touring Car Championship. The change of name and new rules follow the declining interest in the TC1 regulations used by the World Touring Car Championship between 2014 and 2017 and the growing interest among manufacturers in the TCR touring car category.

Team and driver changes

 * As the new WTCR regulations do not allow factory teams, Polestar Cyan Racing will not take part in the new series. Thus Nick Catsburg and Néstor Girolami left the team with Girolami returning to Super TC 2000 Championship and Catsburg joining BMW to race in the FIA World Endurance Championship. Development driver Yvan Muller, who competed as one-off entry last season, formed Yvan Muller Racing with 2017 WTCC champion Thed Björk with the team using the Hyundai i30 N TCR for the season.

A provisional calendar was released in December 2017. In March 2018 an additional round in China was added at the Wuhan Street Circuit.

Sporting regulations

 * With titles for drivers and teams only the new series will receive "World Cup" rather than "World Championship" status. Manufacturers will be able to develop cars for competition that are then sold to privateer entrants and will also be allowed to provide ongoing support and development to those teams.
 * The WTCR series will be capped at 26 entries with up to two wildcards nominated by the organizers at each race weekend. The entry cap will be in place for all races except for Macau where six wildcards were nominated. All Teams will have to enter a minimum two cars with an entry fee of 150,000 Euro.
 * The weekend format was also changed. Now there are three races per weekend instead of two with the first race being held on Saturdays with its own 30-minute qualifying session right after the two Free Practice sessions. On Sundays there is going to be another qualifying session to determine the grid for Race 3, while Race 2's starting grid will have the Top 10 drivers from the session in reverse order.
 * The tires will be supplied by Yokohama and the fuel by Panta.
