GT World Challenge (GTWC)

Definition and Organisational Structure
GT World Challenge (GTWC) is a premier global GT3 racing platform managed and promoted by SRO Motorsports Group, structured around a "global brand, regional execution" model. Built on unified FIA GT3 technical regulations, the platform is divided geographically into four standalone regional championships: GT World Challenge Europe, GT World Challenge Asia, GT World Challenge America, and GT World Challenge Australia. While each regional series operates autonomously with independent championship points, all share GTWC's unified global branding and technical benchmarks. In the 2026 season, the four regional series kick off in close succession within roughly three weeks, staging a combined 29 events and 46 races across 14 countries on four continents.

Competition and Driver Categorisation
At the core of GTWC's sporting structure is the driver categorisation system. Driver line-ups are grouped into distinct competition classes based on their FIA driver ratings, whilst vehicle performance is equalised via the BoP (Balance of Performance) system to ensure a level playing field across diverse GT3 machinery and marques. The European series features four classes: Pro (all-professional line-ups), Gold Cup (pairing Gold and Silver drivers), Silver Cup (all-Silver driver line-ups), and Bronze Cup (pairing a Platinum or Silver driver with a Bronze-rated competitor). The Asian series runs Pro-Am, Silver-Am, Silver, and Am categories, mandating the inclusion of at least one Asian driver. The American series is contested across Pro, Pro-Am, and Am classes, while the Australian series features Pro-Am, Am, and Trophy categories, with the Trophy class dedicated to older-generation GT3 cars.

European Series Race Format
GT World Challenge Europe stands as the flagship and most competitive regional championship in the GTWC ecosystem, boasting the largest grid sizes. The 2026 calendar features 10 rounds, split evenly into five Endurance Cup and five Sprint Cup events. The Endurance rounds comprise the Circuit Paul Ricard 6 Hours, Monza 3 Hours, 24 Hours of Spa, Nürburgring 3 Hours, and Portimão 3 Hours; the Sprint Cup adopts a double-header 60-minute race format per round, visiting Brands Hatch, Misano, Magny-Cours, Zandvoort, and Barcelona. The prestigious 24 Hours of Spa is the marquee round of the European series, expected to draw a record-breaking 70-car entry in 2026. Endurance races award double championship points, while the 24 Hours of Spa carries quadruple points.

2026 Season Technical Regulations and Grid Outlook
The 2026 GTWC manufacturer roster features 10 marques: Aston Martin, Audi, BMW, Corvette, Ferrari, Ford, Lamborghini, McLaren, Mercedes-AMG, and Porsche. The headlining technical highlight is the European debut of the Lamborghini Temerario GT3, which succeeds the Huracán GT3 under the banner of Rutronik Racing and TGI Team by GRT. The Ferrari 296 GT3 EVO, Ford Mustang GT3 EVO, and Porsche 911 GT3 R EVO are also campaigned in updated EVO specifications. The European Endurance Cup grid is capped at a maximum of 60 cars, alongside 45 entries for the Sprint Cup. Notable new entries include Verstappen Racing joining the Pro class with Mercedes-AMG, and Lilou Wadoux making history as the first female driver to contest the Pro class for a factory-backed works outfit.

Chinese Motorsport and the Asian Championship
The 2026 GT World Challenge Asia calendar features the Mandalika round in Indonesia from 2 to 3 May. The presence of Chinese drivers and racing teams continues to expand across the Asian series. Contested under a two-race, 60-minute sprint format per race weekend, all four competition classes mandate at least one Asian driver, providing regional talents with a platform to go wheel-to-wheel against international GT3 drivers. Spanning iconic Asia-Pacific circuits such as Sepang, Mandalika, and Shanghai, GTWC Asia serves as the core pillar of the Asia-Pacific region within the global GT3 racing landscape.
