Polaris RZR Pro R Boost makes 275 hp up to 10,000 feet and 115 degrees, with deliveries starting in November
Polaris adds its first turbocharged powertrain to the 2027 RZR Pro R, and a 400 hp Factory Boost sits above it at $200,000.
A turbo that holds its power
The RZR Pro R Boost makes 275 hp at up to 10,000 feet of elevation or 115 degrees Fahrenheit. [1] If you buy side-by-sides for desert or high-country use, that is the figure Polaris wants you to read first. Polaris says deliveries will begin in November. [2]
The Boost is introduced for the 2027 model year and arrives with the model's first turbocharged powertrain. [2] It uses a 2.0-liter four-cylinder with a 60-millimeter Garrett turbo. [1] The standard naturally aspirated Pro R makes 225 hp. [2]
How it drives
Our reviewer spent a day-long session at Sand Hollow State Park in Southern Utah with Polaris's newest flagship. [1] The throttle can be set to Rock mode for slow climbing and switched to Race mode when terrain opens up. [1]
The reviewer also rolled the RZR over on a long, wide, 35-mph right-hander at Sand Hollow. [1] He was not hurt, and the RZR's rollover protection system kept him safe. [1]
Suspension and spec levels
The Boost uses 29 inches of rear suspension travel. [1] The reviewed buggy's Dynamix DV semi-active suspension adjusts up to 200 times a second. [1]
Every Pro R Boost will come in either Ultimate or Ultra spec. [2] The Ultra models adopt the Dynamix DVS system, which brings the SxS industry's first active sway bar links. [2] Every Pro R, with or without boost, comes pre-wired to accept Dynamix DVS with 12-channel adjustment and active sway bar links. [1]
The Boost pack includes a carbon hood, a genuine racing wheel, upgraded BFGoodrich 32-inch tires, and a bespoke color and graphics order sheet. [2] Zach Blackford is the vehicle architect for the Pro R Boost. [1]
The 400 hp factory boost
The 2027 RZR Pro R Factory Boost produces up to 400 horsepower. [3] That is 125 hp more than the regular Pro R Boost. [3] It has a starting price of $200,000. [3]
Polaris says the Factory Boost is eligible for SCORE, AORC, and Ultra4 competition. [3] It is expected to make its competitive debut at King of the Hammers in 2027. [3]
How it compares
The Can-Am Maverick R is also turbocharged and makes 240 hp. [1] The Pro R Boost makes 275 hp, and the standard Pro R makes 225 hp. [1][2]
What it means for you
If you are shopping for a Pro R, the Boost is the turbocharged option for 2027, and deliveries are due to begin in November. [2] You will choose between Ultimate and Ultra spec, and only the Ultra models adopt Dynamix DVS with its active sway bar links. [2]
If you already own or order a standard Pro R, it comes pre-wired to accept Dynamix DVS. [1] If you want the 400 hp version, the Factory Boost starts at $200,000. [3]
