When Polaris introduced the original Pro R, it reset expectations for what a high-performance side-by-side could be. For 2027, the company has raised the bar once again with the all-new RZR Pro R Boost—a turbocharged desert machine packing an incredible 275 horsepower.

This isn't just another trim level or incremental update. It's the most powerful production RZR Polaris has ever built, combining a new turbocharged engine, advanced cooling technology, intelligent suspension, and premium interior features into one purpose-built performance machine. Whether you're chasing wide-open desert trails, climbing massive dunes, or simply looking for the ultimate sport UTV, the Pro R Boost was designed to dominate.

Turbocharged ProStar Fury Engine Delivers 275 Horsepower

The centerpiece of the 2027 RZR Pro R Boost is Polaris' new 2.0-liter ProStar Fury turbocharged engine. Producing an astonishing 275 horsepower at 7,000 RPM and 215 lb-ft of torque at 4,000 RPM, it delivers explosive acceleration while maintaining smooth, controllable power throughout the RPM range.

One of the biggest advantages of turbocharging is consistent performance at elevation. Unlike naturally aspirated engines that lose power as altitude increases, the Pro R Boost continues pulling hard even above 10,000 feet, making it an excellent choice for riders who frequently explore mountain trails or high-elevation dunes.

Polaris also redesigned the shift interface for 2027, giving the transmission a more precise mechanical feel when selecting Drive, Reverse, or Park. It's a small detail, but one that improves confidence every time you climb behind the wheel.

Built to Stay Cool in Extreme Conditions

Producing 275 horsepower creates serious heat, especially in desert environments where temperatures regularly exceed 100 degrees. Polaris addressed that challenge with one of the most advanced cooling systems ever installed in a production UTV.

Dual-Radiator Design

Instead of relying on a single cooling system, the Pro R Boost separates cooling responsibilities between two radiators:

• Rear high-temperature radiator dedicated to engine cooling
• Front low-temperature radiator designed specifically for the turbocharger and transmission

This layout allows each system to operate more efficiently under demanding conditions.

Functional Roof Scoop

A new roof-mounted air scoop channels fresh air directly into the rear radiator. Because the intake is positioned above the vehicle, cooling performance remains effective regardless of windshield or light bar configurations.

Cooler Interior Temperatures

Polaris also focused on rider comfort by moving more heat away from the cockpit. Additional fresh-air intake points and 360-degree rotating air vents help reduce footwell temperatures, making long rides considerably more comfortable—even during triple-digit desert heat.

FOX Live Valve Suspension Gets Even Smarter

Putting 275 horsepower to the ground requires more than just big shocks. That's why Polaris equipped the Pro R Boost with FOX 3.0 Live Valve X2 Internal Bypass shocks, managed by the company's latest electronic suspension systems.

The Ultimate model features DYNAMIX DV, while the Ultra receives the upgraded DYNAMIX DVS system.

Both systems constantly monitor terrain and automatically adjust compression and rebound damping in real time, helping the vehicle stay composed through whoops, g-outs, rocks, and rough desert terrain.

New tuning updates for the 2027 model include:

• Improved G-out protection
• Enhanced rear bump control
• Faster suspension response
• Better overall stability at speed

The result is a suspension system that continually adapts to changing terrain without requiring driver input.

Premium Interior Technology

The cabin has evolved into one of the most advanced interiors available in a sport side-by-side.

10.4-Inch RIDE COMMAND Display

At the center of the dashboard sits Polaris' largest touchscreen to date. The 10.4-inch RIDE COMMAND display includes:

• Split-screen capability
• 3D trail mapping
• Group Ride tracking
• Integrated rear camera
• Future Apple CarPlay® compatibility

Navigation, vehicle information, and camera views are all easily accessible from one intuitive display.

Heated and Ventilated Pro Climate Seats

The Pro R Boost also introduces Pro Climate seats that are both heated and ventilated. Whether you're heading out on a cold morning ride or spending hours in summer heat, drivers and passengers can choose the level of comfort that suits the conditions.

Rockford Fosgate Stage 4 Audio

For riders who enjoy music on the trail, Polaris includes a 1,500-watt Rockford Fosgate Stage 4 audio system capable of delivering powerful sound even at higher speeds.

RZR Pro R Boost Ultimate vs. Ultra

Both the Ultimate and Ultra are available in two-seat and four-seat configurations. Fuel capacity has also increased, with 14.7 gallons available on two-seat models and 17.4 gallons on four-seat versions.

Here's how the two trims compare:

The Ultra trim adds several premium cosmetic and suspension upgrades for buyers who want the most capable Pro R Boost Polaris offers.

A New Standard for High-Performance UTVs

Beyond the impressive numbers, the 2027 RZR Pro R Boost represents a significant step forward in high-performance off-road engineering.

Its aggressive front-end styling, highlighted by the signature Fang LED lighting, matches the performance underneath. The turbocharged engine, sophisticated cooling system, electronically controlled suspension, and premium technology package work together to create one of the most complete sport UTVs currently available.

For riders who demand maximum power without sacrificing comfort, technology, or durability, the 2027 Polaris RZR Pro R Boost establishes a new benchmark. Every manufacturer competing in the high-performance side-by-side segment now has a new target to chase.
