Polaris has officially unveiled the 2027 RZR Pro R Boost, the most powerful production side-by-side the company has ever offered. Designed to push the limits of off-road performance, the new model produces an impressive 275 horsepower thanks to the addition of a turbocharged version of Polaris’ 2.0-liter ProStar Fury engine.
A 66-millimeter Garrett turbocharger and liquid-to-air intercooler helps deliver 50 more horsepower than the naturally aspirated Pro R while maintaining performance at elevations of up to 10,000 feet. Â Engineers also upgraded the continuously variable transmission (CVT), strengthened the driveline, enlarged the half shafts, and redesigned the cooling system to handle the additional power and torque. A roof-mounted air intake directs airflow to the rear-mounted radiator, helping maintain consistent performance in extreme conditions.
The 2027 Pro R Boost will be available in both Ultimate and Ultra trim levels, with the latter receiving Polaris’ advanced Dynamix DVS suspension system, active sway-bar technology, carbon-fiber components, and BFGoodrich tires. Pricing begins at $49,999 for the two-seat Ultimate model, while four-seat and Ultra variants command higher price tags. Deliveries are expected to begin in November.
