2027 Polaris RZR Pro R Boost: 275 Horsepower Is Another Level

Polaris has spent nearly two decades pushing the performance side-by-side category forward, and for 2027 it is taking another significant step with the introduction of the all-new RZR Pro R Boost. The big news is right there in the name: Polaris has added turbocharging to its 2.0-liter ProStar Fury engine, pushing output to an incredible 275 horsepower.

But there is a lot more going on here than simply bolting a turbo onto the existing Pro R. Polaris has upgraded the cooling system, clutching, transmission, front drive system, half shafts and other driveline components to deal with the additional power. Throw in new suspension technology on the Ultra trim, Apple CarPlay compatibility and both two- and four-seat configurations, and the RZR Pro R Boost looks like one of the biggest performance updates to the RZR lineup in years.

2027 Polaris RZR PRO R Boost

275 Horsepower From a Turbocharged 2.0L

Obviously, the headline feature is the engine. The RZR Pro R Boost gets a turbocharged ProStar Fury 2.0-liter production engine producing 275 horsepower. That's a substantial jump in power and puts an enormous amount of performance behind your right foot.

Polaris says the combination of increased torque and an optimized power-to-weight ratio provides quicker acceleration and immediate throttle response while maintaining smooth power throughout the RPM range. Just as importantly for riders heading into the mountains, the turbo system has been designed to maintain peak power at elevations of up to 10,000 feet.

That last part could be a big deal. Anyone who has spent time riding naturally aspirated machines at elevation knows how noticeable the power loss can become. Maintaining the Boost's performance as the elevation climbs should make this machine particularly interesting for riders who regularly tackle high-altitude dunes and mountain terrain.

Built to Handle 275 Horsepower

Making 275 horsepower is one thing. Getting that power reliably to the ground in sand, rocks and desert terrain is another. Polaris appears to have spent considerable effort upgrading the supporting systems rather than simply chasing a horsepower number.

Performance and Driveline Highlights

  • New high-capacity clutching system
  • Larger clutch design
  • Increased clutch airflow
  • Additional cooling fins to help manage heat
  • Designed to improve belt life during demanding riding
  • New dual-radiator cooling architecture
  • Improved cooling for the engine, turbo and transmission
  • Stronger front drive system
  • Upgraded transmission
  • Reinforced driveline components
  • Strengthened half shafts
  • Updated engine calibration
  • Refined CVT tuning
  • New engine isolators designed to reduce noise and vibration

We like seeing this kind of attention paid to everything surrounding the engine. With this much horsepower on tap, cooling, belt durability and driveline strength become every bit as important as the horsepower figure itself. Polaris says the changes are intended to provide a more direct transfer of power while maintaining consistent performance under demanding conditions.

2027 Polaris RZR PRO R Boost Ultimate

RZR Pro R Boost Ultimate

The Ultimate trim pairs the new 275-horsepower powertrain with desert-tuned DYNAMIX suspension.

Polaris has added new G-out protection and rear bump control features, designed to give the suspension better control when the terrain gets rough and speeds start climbing. This should make the Ultimate an interesting choice for riders who want the Boost powertrain and active suspension without moving all the way up to the Ultra.

Ultimate Highlights

  • 275-horsepower ProStar Fury 2.0L Turbo
  • Desert-tuned DYNAMIX suspension
  • New G-out protection
  • New rear bump control
  • Available in 2-seat and 4-seat configurations
  • Apple CarPlay compatibility

2027 Polaris RZR PRO R Boost Ultra

RZR Pro R Boost Ultra

The Ultra is where Polaris really turns things up.

Instead of the Ultimate's DYNAMIX system, the Ultra receives race-proven DYNAMIX DVS suspension along with what Polaris calls the industry's first active sway bar links. The system can make adjustments up to 200 times per second, giving the suspension another tool for controlling the chassis and responding to changing terrain.

There are also several visual and hardware upgrades that distinguish the Ultra from the Ultimate.

Ultra Highlights

  • 275-horsepower ProStar Fury 2.0L Turbo
  • DYNAMIX DVS suspension
  • Active sway bar links
  • System adjusts up to 200 times per second
  • Carbon-fiber hood
  • Carbon-fiber seat bezels
  • MPI GT steering wheel
  • 32-inch BFGoodrich tires
  • Exclusive paint and graphics
  • Available in 2-seat and 4-seat configurations
  • Apple CarPlay compatibility

The active sway bar technology may ultimately be one of the most interesting parts of the new machine. Horsepower gets the attention—and 275 horsepower certainly deserves plenty of it—but being able to better manage that performance through suspension and chassis control could have just as much impact from behind the wheel.

More Technology and Connectivity

Polaris is also bringing Apple CarPlay compatibility to the RZR Pro R Boost. For riders already using their phones for music, navigation and communication, that should make the RZR's technology feel more integrated with what they use every day.

Polaris also says a broad selection of accessories will be available, allowing owners to customize the Boost for their particular type of riding.

2027 Polaris RZR Pro R Boost Models

The new Boost lineup will include four basic model and trim combinations:

  • 2027 RZR Pro R Boost Ultimate – 2 passenger
  • 2027 RZR Pro R Boost Ultra – 2 passenger
  • 2027 RZR Pro R 4 Boost Ultimate – 4 passenger
  • 2027 RZR Pro R 4 Boost Ultra – 4 passenger

Pricing for the lineup starts at $49,999 U.S. MSRP. The press release does not provide individual MSRP or color information for each of the four models.

The RZR Pro R Boost is scheduled to begin arriving at Polaris dealerships in November 2026.

Our Take

The 275-horsepower number is going to grab everyone's attention, and for good reason, but we're just as interested in everything Polaris changed around the engine. A bigger clutch, additional cooling, reinforced driveline components and upgraded suspension show that the Pro R Boost was developed as more than simply a horsepower upgrade.

Then there's the Ultra. Active sway bar links capable of making adjustments up to 200 times per second combined with DYNAMIX DVS could make the Ultra's suspension technology every bit as noteworthy as its turbocharged engine.

The original RZR helped redefine what a sport side-by-side could be back in 2007. Nearly 20 years later, 275 horsepower from a production RZR is a pretty wild indication of just how far this category has come.

Competitor Models

With 275 horsepower, the RZR Pro R Boost sits at the extreme end of the factory sport side-by-side market, but Polaris isn't alone in chasing huge performance. Two of its most interesting competitors are the 2027 Kawasaki TERYX H2 and 2027 Can-Am Maverick R. All three offer serious horsepower and advanced suspension technology, but they get there in very different ways.

2027 Kawasaki TERYX H2 Limited eS

The new two-seat TERYX H2 brings Kawasaki's supercharged H2 powertrain into a shorter sport platform. Its 999cc mechanically supercharged inline-four produces 250 horsepower and 146.2 lb-ft of torque, compared with 275 horsepower and 215 lb-ft from the RZR Pro R Boost's 2.0-liter turbocharged inline-four.

Kawasaki pairs its engine with a CVT and gives the TERYX H2 a 101-inch wheelbase, 74-inch width, 23.2 inches of front suspension travel, 24 inches of rear suspension travel and up to 16.9 inches of ground clearance.

The TERYX H2 Limited eS is the closest comparison to the RZR Pro R Boost Ultra from a suspension-technology standpoint. Kawasaki's KECS+ system combines FOX 3.0 Live Valve Internal Bypass shocks with an electronically controlled FOX Live Valve Sway Bar Disconnect. Polaris answers with DYNAMIX DVS, FOX 3.0 Live Valve X2 Internal Bypass shocks and electronically controlled stabilizer-bar links capable of locking and unlocking up to 200 times per second.

Pricing also separates the two. The TERYX H2 starts at $32,899, while the more comparable Limited eS starts at $41,399. The RZR Pro R Boost starts at $49,999.

The Kawasaki gives up 25 horsepower to the Polaris, but counters with a mechanically supercharged engine, shorter wheelbase and substantially lower starting price.

2027 Can-Am Maverick R X rs

The Maverick R offers another completely different take on extreme side-by-side performance. Its 999cc turbocharged Rotax three-cylinder produces 240 horsepower, putting it 35 horsepower below the 275-horsepower RZR Pro R Boost.

The major mechanical difference is the transmission. Polaris uses its automatic PVT system, while Can-Am uses a seven-speed dual-clutch transmission with High and Extra Low ranges. That gives the Maverick R a very different power-delivery experience from both the RZR Pro R Boost and TERYX H2.

The Maverick R X rs provides 25 inches of front suspension travel and is available with Can-Am's Smart-Shox electronic suspension system. It rides on 32-inch ITP Tenacity XNR tires mounted to 16-inch flow-formed beadlock wheels.

The Maverick R X rs starts at $44,199 before adding the available Smart-Shox option, placing its starting price between the TERYX H2 Limited eS and RZR Pro R Boost.

Three Different Ways to Build an Extreme-Performance Side-by-Side

What makes this group particularly interesting is that there isn't one engineering formula being followed by everyone.

  • Polaris RZR Pro R Boost: 275-hp 2.0L turbocharged inline-four, automatic PVT and available DYNAMIX DVS active suspension with electronic stabilizer-bar links.
  • Kawasaki TERYX H2: 250-hp 999cc mechanically supercharged inline-four, CVT and available KECS+ with FOX Live Valve Sway Bar Disconnect.
  • Can-Am Maverick R: 240-hp 999cc turbocharged three-cylinder, seven-speed DCT and available Smart-Shox electronic suspension.

The RZR Pro R Boost brings the biggest horsepower and torque numbers of the three, while Kawasaki's supercharged engine and Can-Am's seven-speed DCT give those machines distinctly different personalities. Suspension technology has also become nearly as important as horsepower, with Polaris, Kawasaki and Can-Am each using electronically controlled suspension to help drivers put increasingly serious levels of performance to the ground.
