Motorsport UK are pleased to publish the 2026 Karting Yearbook.  

December 2025 will mark the release of the twenty-ninth edition of the Karting Yearbook, following the successful re-homologation of all the classes featured in the Yearbook. 

Some of the changes to the 2026 technical regulations include the successful homologation of the MightE Cadet and Rotax E10 Cadet as Motorsport UK continues to introduce electric powertrains into the sport. The regulations for these Classes will be available on the Motorsport UK Resource Centre under the filter ‘Technical: Kart’.  

The Tillotson T4 Junior & Senior Class regulations have been added into the appropriate sections of the Yearbook. 

Alongside the additions of the two electric Cadet Classes, all other key technical changes are outlined in red text and all competitors, entrants, and parents are encouraged to read through their specific class regulations to make sure they are ready for the 2026 season! 

The Motorsport UK 2026 Karting Yearbook can be found here and if you have any questions about next years change, please contact the Karting team at kart@motorsportuk.org
