The 2026 Ultimate Cup European Series is scheduled to be the eighth season of the Ultimate Cup European Series. The Ultimate Cup Series is a program comprising multiple endurance and sprint championships across different classes of motor racing. 2026 will see the championship hold a two-race winter series ahead of its main season for the first time.
The 2026 calendar was announced on 30 July 2025. The series will no longer hold two events at Circuit Paul Ricard, instead holding the final round at Algarve International Circuit and also making its debut at Circuit de Spa-Francorchamps. In November 2025, the calendar was updated: The round at Motorland Aragón was replaced with a round at Circuito de Navarra one week earlier, while the final round at Algarve International Circuit was brought forward by three weeks.
The European Endurance Prototype Cup was only open to Nova Proto NP02 cars.
The Hoosier Formula Cup will be open to Tatuus F3R T318 cars powered by either Alfa Romeo or Renault engines on 13-inch Hoosier tyres.
The Calendar of the Ultimate Winter Cup was announced at the launch of the winter series on 19 June 2025. The series will consist of two race weekends, held across the Iberian peninsula.
