  "account": "The FIA is set to propose a modification in turbo restrictor regulations for the 2027 World Rally Championship to ensure a small power advantage for Rally1 cars over Rally2 cars. This change aims to prevent Rally2 cars, equipped with the FIA's 7,500-euro update kit, from consistently outperforming the new top-class WRC27 cars. The 2027 season will see the debut of new WRC27 cars and Rally2 cars, both adhering to separate technical regulations and expected to deliver similar performance levels. Rally2 cars with the update kit will weigh 10 kilograms less than the WRC27 cars. The FIA has also allowed Rally2 cars without the update kit to compete in a separate Rally2/WRC2 class. However, due to the close performance between WRC27, Rally2 kit, and Rally2 cars, the FIA has introduced a regulation change to differentiate the two classes. According to FIA technical director Xavier Mestelan Pinon, Rally1 and Rally2 Kit cars will be permitted to use a 33mm turbo restrictor, while Rally2 cars without the update kit will need to run a 32mm turbo restrictor. This amendment is anticipated to result in a 15-horsepower difference between the two classes, with Rally2 cars producing 290 horsepower. The proposed regulation change will be put to a vote at the next FIA World Motor Sport Council meeting on October 15.",
