Two beastly machines emerged from the mad-science realms of the UTV world last year: Can-Am's Maverick R3 and Polaris' RZR Pro R Factory. Minnesota outfit Polaris introduced the latter as the chosen rig for an industry-first factory-backed race team, and it won out of the gate. Team driver Brock Heger won three of the four races in the SCORE series, including the Baja 1000, driving off with the series' Pro UTV Open Class Championship and getting Polaris the Manufacturer's Championship. Moving into this year, a modified version of the first-gen Pro R Factory won its class at the Dakar Rally as part of Sebastien Loeb Racing, then Heger piloted the standard factory rig to victory in the Desert Race at the King of the Hammers. For this weekend's San Felipe 250, the first race in SCORE's 2024 schedule, Polaris introduced the second-gen RZR Pro R Factory, improved with expertise and parts from car-based motorsports.
