2026 AORRC classes revealed

Being in essence a merger between Best In The Desert and Unlimited Off-Road Racing, the American Off-Road Racing Championship understandably created its rulebook by synthesizing the regs from the two series.

The moto and quad classes adopted the BITD rules, while most of the four-wheelers will use UNLTD’s. UTVs are a mix of both.

Car / Buggy

Although based on the UNLTD rulebook, most of the car and buggy categories maintain the same name as their BITD counterparts such as Class 1 and the new-for-2025 Super 10.

The AORRC’s Class 1, for example, is BITD’s Class 1500. Class 10 is Class 1000, while Class 5 Unlimited and Class 12 are respectively based on BITD Classes 5000 and 1100. Class 1/2-1600, a common face in many desert series, was what BITD called Class 2000.

The much beloved Class 11 will also be part of the AORRC program.

Truck

Trucks are also based on UNLTD, meaning BITD drivers would have to account for some slight changes.

Following SCORE’s Trophy Truck model, BITD’s Trick Truck category has been divided into four-wheel- and two-wheel-drive Unlimited Trucks. Class 1300 has been converted into Unlimited Truck Legends, while Class 6100 is for Spec trucks.

Other class name changes for BITD racers to get used to include:

  • Class 1200 → Stock Production Truck Full
  • Class 1700 → Jeepspeed Challenge
  • Class 2700 → Jeepspeed Cup
  • Class 3700 → Jeepspeed Outlaws

UTV

UTVs will use a combination of UNLTD and BITD rules. There will also be a category for electric and hybrid UTVs, which are still in their infancy but have seen increased relevance like the upcoming Segway Super Villain SX20T hybrid; a gas-based version raced BITD’s Silver State 300 in May.

The AORRC has also introduced a pipeline program for UTV drivers to move up from Sportsman to Pro classes with their existing cars. R/H2 drivers start in UTV Stock R/H2 before graduating to UTV Pro Stock R/H2 and ultimately reaching UTV Pro. Meanwhile, those not in R/H2 begin with UTV Stock, then head up UTV Pro Stock and either UTV Pro Turbo or UTV Pro.
