Ahead of the 2025 season, Best In The Desert has made various updates to the classes for UTVs and introduced a new one for unlimited cars.

On the UTV side, the UTV Pro Turbo and UTV Pro Open classes have been consolidated into a single UTV Pro class. UTV Super Stock and UTV Super Stock R are also renamed to UTV Pro Stock and UTV Pro Stock R, respectively. While rule changes for the latter are fairly minute, the Pro class merger comes in line with a broadened rulebook to encourage participation.

UTV Pro drivers can earn points at the upcoming King of the Hammers if they enter in an Open or Pro Modified UTV. The same applies to UTV Pro Stock and Pro Stock R if they race in a Stock UTV.

“As the UTV racing world continues to innovate and push boundaries, we’ve worked tirelessly to ensure BITD stays at the forefront of the sport,” reads a series statement. “After months of collaboration with industry leaders, OEM manufacturers, and our dedicated Tech Team, we are proud to announce a series of carefully considered updates for the 2025 season.

“These changes represent countless hours of research, discussions, and a commitment to growing the sport while maintaining its integrity. We believe these updates will foster even more competitive and exciting racing for all participants.”

UTVs, with enough modifications to the point where they are hardly UTVs anymore, can theoretically also take part in the newly formed Super 10 category. The class is designed for open-wheel cars with unlimited suspension and an open body style, though engines are limited to those with one to four cylinders. It is not to be confused with Class 1000, which is BITD’s version of Class 10.

Super 10 will follow most of the same regulations as other Car/Truck classes, though exceptions include permitting the use of turning and steering brakes (a rule that also exists for Class 1000).

Besides the four-cylinder limit, the Super 10 engine can only have four valves per cylinder and two camshafts at most. Engines below 2000cc are to be forced induced while those beyond that must be naturally aspirated. Rotary engines are forbidden while the exhaust and intake are open for modification. Class 1000 overlaps in some respects, though it requires the engine to be mass produced and “readily available to the general public.” One- and two-seat cars are permitted.

“Due to popular demand, we’re excited to introduce the all-new Super 10 class—a high-performance Car/Truck category built for those ready to push the limits,” BITD said. “This class is open to all 1–4-cylinder unlimited cars and is designed to welcome highly modified UTVs and other extreme off-road machines that meet the official BITD regulations. While Super 10 does not replace Class 10, it creates an opportunity for racers to showcase their innovation, skill, and the raw power of their modified vehicles on the toughest terrain.”
