The Fanatec GT World Challenge Europe Endurance Cup powered by AWS, formerly for sponsorship reasons the Blancpain Endurance Series from 2011 to 2015 and Blancpain GT Series Endurance Cup from 2016 to 2019, is a sports car racing series developed by SRO Motorsports Group and the Royal Automobile Club of Belgium (RACB) with approval from the Fédération Internationale de l'Automobile (FIA). It features grand tourer racing cars modified from production road cars complying with the FIA's GT3 regulations. The series's goal is to be an endurance racing championship for GT3 cars, similar to the FIA World Endurance Championship which were using GTE cars and Le Mans Prototypes. The series was primarily sponsored by Swiss watchmaker Blancpain, and the company's Lamborghini Super Trofeo series serve as support races. In 2019, SRO announced that their sponsorship deal with Blancpain had been discontinued and the series was renamed the GT World Challenge Europe Endurance Cup for the 2020 season.
