Polaris Unleashes the Most Powerful UTV Ever: The 400-HP RZR Pro R Factory Boost

Polaris has just unveiled the 2027 RZR Pro R Factory Boost, a race-spec UTV that boasts an astonishing 400 horsepower. This beast of a machine is designed to dominate every off-road race in the world, with a 2.0-liter ProStar Fury turbocharged four-cylinder engine that’s been cranked up to deliver ‘up to’ 400 horsepower. The RZR Pro R Factory Boost has a base price of $200,000 and features a host of goodies, including a 45-gallon long-range fuel cell, a MoTeC electronics package, and DYNAMIX DV Live Valve shocks. The UTV also has a redesigned body for optimal airflow and less drag, as well as a FOX steering damper for better high-speed control. Polaris states that the RZR Pro R Factory Boost isn’t replacing its Gen 2 RZR Pro R Factory race machine, but rather complementing it in the lineup. The first customers have until February 15th, 2027 to place their orders for the first batch of UTVs, which will make its dynamic debut at the King of the Hammers next year.
