Wheel-to-wheel racing kicked off at the RTX Karting RMC Winter Trophy Sunday. Now a three-race series due to issues with timing and scoring on Saturday, qualifying on Friday afternoon set the grid for the prefinals on Sunday. With Prefinal A and B for classes over 36 entries, the top-18 in each prefinal transferred directly to the main event with all other class prefinals setting the grid for the finals.

The second running of the Rotax Winter Trophy has hit the spot in 2023, growing the two-round series to a total of 100 entries. With an increase in participants of 66.6% on the first edition of the Rotax MAX Challenge Winter Trophy USA in Florida last year, the interest in the championship saw drivers coming from 14 different nations to compete for the titles and RMC Grand Finals tickets.
