The second half of the 2026 ProKart Challenge began over the August 15-16 weekend at Sonoma Raceway. The Sonoma, California circuit welcomed the series for the second of back-to-back trips, hosting the fourth round of the season championship on the ‘Reverse National’ layout. Picture-perfect weather greeted the nearly 160 entries across 11 categories for the weekend.

Qualifying Practice, Heat Races, and Pre-Finals are now in the books, and the only session that remains of any importance is the Finals on Saturday. With RMC Grand National Championship titles on the line, one of the best days of the year in all of karting happens tomorrow.

The day started under cool and calm conditions at the Circuito Internazionale di Napoli in Sarno, Italy, but the track action heated up throughout the day, concluding with three Qualifying Practice sessions. Setting the grids in Micro MAX, Mini MAX, and MAX DD2 Masters, the remaining classes will qualify tomorrow, with wheel-to-wheel action to follow. Of note, Non-Qualifying Practice 6 for Junior MAX Even, Senior MAX Odd and Even, MAX DD2 Odd and Even were cancelled today due to heavy rain, as those classes still have Non-Qualifying Practice 7 tomorrow morning.

The RMC Grand Finals 2024 roared to life today at 09:00 with the Non-Qualifying Practice Sessions for all categories, held at the legendary Circuito Internazionale di Napoli. Under perfect weather conditions, all drivers were seen fine-tuning their skills on the track, setting the stage for an exciting week of racing action.

Last weekend, KartCenter Campillos hosted the first edition of the Rotax MAX Challenge Winter Cup organized by WSK Promotion. The mixed weather conditions added an extra layer of excitement to the already thrilling racing spectacle, with rain and sunshine alternating throughout the weekend, providing a true test of the drivers’ skills.
