The 2020 Polaris RZR PRO XP 4 introduced Polaris’ new Pro-platform chassis to the four-seat sport UTV market. Announced in October 2019, it combined a 181-horsepower turbocharged engine with a 125-inch wheelbase, 64-inch width, 22 inches of usable suspension travel and a cockpit designed around all four occupants.
The PRO XP 4 was more than a stretched version of the two-seat 2020 RZR PRO XP. Polaris added elevated rear seating, increased rear legroom and shoulder room, a 13-gallon fuel tank and fold-flat rear seats that substantially expanded its cargo capacity.
Why the RZR PRO XP 4 Was Important
Polaris had been building four-seat RZRs since the original RZR 4 800 arrived for the 2010 model year. The RZR XP 4 900, XP 4 1000 and XP 4 Turbo progressively added more power and suspension capability, but the 2020 PRO XP 4 represented a more fundamental redesign.
The new platform used a one-piece welded chassis, revised drivetrain, redesigned clutch system and a more spacious cockpit. Comfort, storage, passenger visibility, accessory integration and onboard technology received nearly as much attention as engine output.
That broader approach made the PRO XP 4 an important milestone in the history of the Polaris RZR. It established the basic four-seat Pro-platform layout that Polaris continued to develop in later model years.

181-Horsepower Turbocharged Engine
The PRO XP 4 used the same 925cc turbocharged twin-cylinder engine introduced in the two-seat PRO XP. Polaris rated it at 181 horsepower and calibrated the power delivery to provide strong acceleration between approximately 20 and 50 mph.
Peak power was only part of the story. Polaris also redesigned the transmission and driveline for the new platform. The company claimed the transmission offered 39 percent greater durability, while stronger axles and an upgraded front drive system were intended to withstand the loads produced by the engine and heavier four-seat chassis.
The PRO XP platform also received a redesigned clutch system. During our test of the two-seat model on the Rubicon Trail, we found that its smoother, earlier clutch engagement provided better low-speed control than the preceding RZR Turbo S, although the factory Low-range gearing remained taller than we preferred.

125-Inch Wheelbase and 64-Inch Width
The PRO XP 4 measured 64 inches wide and rode on a 125-inch wheelbase. That wheelbase was 29 inches longer than the two-seat PRO XP’s 96-inch measurement.
The added length gave Polaris room to improve rear-passenger accommodations while increasing stability in rough terrain, high-speed whoops and dune transitions. Its 64-inch width also made the PRO XP 4 more appropriate for many recreational trails than the 72-inch RZR Turbo S 4.
High-clearance front and rear suspension components helped produce a claimed 14.5 inches of ground clearance. The PRO XP 4 rode on 30-inch Maxxis Carnivore 2.0 tires, which were large for a factory-equipped 64-inch sport UTV at the time.
Designed Around Four Occupants
One of the most important changes was the attention given to the rear passengers. Polaris elevated the rear seating position to improve forward visibility and claimed four additional inches of shoulder room and three additional inches of legroom compared with the preceding four-seat platform.
The driver and front passenger received sliding seats, while the steering wheel offered both tilt and telescoping adjustment. Front and rear half doors were standard across the original lineup.
Polaris also introduced fold-flat rear seats. Folding the rear seats created more than 16 cubic feet of enclosed storage space behind the front occupants, making the vehicle more practical for camping equipment, tools and other riding gear when all four seats were not needed.
PRO XP 4, Premium and Ultimate Trims
Polaris initially offered the 2020 RZR PRO XP 4 in three trim levels:
- PRO XP 4: The base model included the 181-horsepower engine, 64-inch chassis, 30-inch tires, half doors and fold-flat rear storage.
- PRO XP 4 Premium: Added upgraded interior equipment, premium paint, a more extensive lighting package, multipoint harnesses and additional storage features.
- PRO XP 4 Ultimate: Added DYNAMIX 2.0 active suspension, RIDE COMMAND, steering-wheel controls and a factory Rockford Fosgate audio system.
Original starting prices were $25,699 for the base PRO XP 4, $27,999 for the Premium and $32,299 for the Ultimate. These figures represent the announced 2020 model-year MSRPs and do not reflect current used-vehicle values.
DYNAMIX 2.0 Active Suspension
The Ultimate trim received FOX 2.5 Live Valve shocks controlled by Polaris’ DYNAMIX 2.0 system. Drivers could change suspension settings using controls mounted on the steering wheel instead of navigating through the touchscreen.
Comfort, Sport and Firm calibrations allowed the suspension to adapt to different terrain and driving styles. The steering-wheel-mounted “X” button immediately commanded maximum damping to help the suspension resist bottoming during an unexpected impact.
This technology was especially relevant in a four-seat vehicle. The longer chassis and changing passenger load placed additional demands on suspension control, and active damping helped manage body movement while maintaining ride comfort.
How the Original PRO XP 4 Fits into the Current RZR Family
The original PRO XP 4 established the 64-inch, turbocharged four-seat branch of Polaris’ modern RZR lineup. Polaris subsequently introduced the wider Turbo R and Pro R platforms for riders focused on dunes and open desert, while continuing to develop the more trail-friendly PRO XP.
For 2025, Polaris substantially updated the Pro-platform interior with improved airflow management, redesigned seats, more complete doors, revised storage and updated lighting. Our 2025 Polaris RZR Pro lineup overview explains those later changes and the differences among the Pro XP, Pro S and Pro R.
The basic role established in 2020 remains relevant: the PRO XP 4 combines turbocharged performance and room for four occupants with a 64-inch width that is more versatile on mixed recreational terrain than Polaris’ wider flagship models.

What is the difference between the Premium and Ultimate trims?
The Premium added interior, lighting, harness and appearance upgrades. The Ultimate added DYNAMIX 2.0 active suspension, RIDE COMMAND, steering-wheel controls and a Rockford Fosgate audio system.
Was this the first four-seat Polaris RZR?
No. The 2010 RZR 4 800 was Polaris’ first factory four-seat RZR. The 2020 PRO XP 4 was the first four-seat model built on the redesigned Pro-platform chassis.
Final Takeaway
The 2020 Polaris RZR PRO XP 4 represented a major generational change rather than a routine four-seat model update. Its 181-horsepower engine delivered the expected performance, but the more important advances were the stronger Pro chassis, longer wheelbase, improved passenger accommodations, fold-flat storage and available DYNAMIX 2.0 technology.
Those features helped move the four-seat performance UTV beyond simply adding two seats to an existing sport machine. The PRO XP 4 was developed as a complete four-passenger platform and became an important chapter in the evolution of the Polaris RZR.
