Polaris has officially launched the Polaris RZR Pro R Factory Boost Unveiled With 400 HP, a purpose-built desert racing UTV producing up to 400 horsepower. Introduced during the 2026 Camp RZR event at the Glamis Imperial Sand Dunes, the new race machine combines a turbocharged 2.0-liter engine with an extended wheelbase, reinforced chassis, carbon fiber bodywork, and upgraded suspension. With a starting price of $200,000, the Factory Boost represents a significant addition to Polaris’ factory-built racing lineup.
Unlike the production RZR Pro R Boost, this new machine is engineered specifically for competition. Developed by Polaris engineers and manufactured in Roseau, Minnesota, the Factory Boost builds on the company’s existing Gen 2 RZR Pro R Factory race platform while introducing substantial changes designed for high-speed desert racing.

400-Horsepower Turbocharged ProStar Fury Engine
At the heart of the Polaris RZR Pro R Factory Boost is a race-tuned, turbocharged ProStar Fury 2.0-liter four-cylinder engine producing up to 400 horsepower.
That substantial power output is designed to give competitors the acceleration and high-speed performance needed for demanding desert racing environments, where maintaining momentum through sand washes, open terrain, and rough sections can make a significant difference.
The new race machine builds on the foundation of the recently introduced production RZR Pro R Boost, but incorporates competition-specific engineering and components developed through Polaris’ factory racing program.
Rather than replacing the existing Gen 2 RZR Pro R Factory, the Factory Boost joins it as another option for professional and privateer race teams looking for a factory-developed competition vehicle.

Longer Wheelbase and Reinforced Chassis
One of the most significant changes to the RZR Pro R Factory Boost is its redesigned chassis.
Polaris has extended the wheelbase by 6.5 inches, bringing the overall measurement to 111 inches. The additional length is intended to improve straight-line stability and control when traveling across rough terrain at high speeds.
Engineers have also increased the tubing diameter in key structural areas to improve chassis strength and rigidity.
The redesigned cockpit is two inches wider, providing additional space and legroom for the driver and co-driver. An all-new roll cage further strengthens the competition-focused design.
Together, these changes move the Factory Boost further away from a traditional recreational side-by-side and closer to a dedicated desert race car.

Carbon Fiber Bodywork Designed for High-Speed Racing
The RZR Pro R Factory Boost features full carbon fiber bodywork developed to reduce weight and improve aerodynamic efficiency.
Polaris engineers used computational fluid dynamics (CFD) to evaluate airflow at speeds exceeding 100 mph. This development process helped shape the redesigned cage, arched roofline, and rear bodywork.
Aerodynamics become increasingly important in open desert racing, where vehicles spend extended periods operating at high speeds.
The combination of lightweight carbon fiber panels and a carefully shaped exterior is intended to improve airflow while supporting the vehicle’s overall performance.

Race-Tuned FOX DYNAMIX DV Suspension
Suspension performance is another major focus of the new Factory Boost.
The race machine features three-inch internal bypass DYNAMIX DV Live Valve shocks with upgraded one-inch shock shafts.
These competition-specific components are engineered to withstand the repeated impacts and demanding conditions associated with long-distance desert racing.
Polaris has also developed race-specific suspension tuning to provide improved control across changing terrain.
A FOX steering damper comes standard, helping reduce steering disturbances caused by large impacts and rough terrain.
The suspension package reflects the experience Polaris has gained through its RZR Factory Racing program and the continued development of the Gen 2 RZR Pro R Factory platform.

45-Gallon Fuel Cell and Upgraded Electronics
Long-distance desert racing requires more than horsepower and suspension travel. Fuel capacity, electronics, and reliability are equally important.
The RZR Pro R Factory Boost features a 45-gallon fuel cell, an increase of 11 gallons compared with the previous RZR Pro R Factory’s 34-gallon system.
According to Polaris, the larger fuel capacity extends the machine’s range beyond 200 miles, potentially allowing race teams to reduce the number of fuel stops during competition.
The Factory Boost also receives a fully integrated MoTeC electronics package featuring an upgraded M150 ECU.
Two power distribution modules replace the previous model’s single-module configuration, providing additional electrical distribution and control capabilities.
These upgrades are designed to support the increasingly complex demands of professional off-road racing.

Polaris RZR Pro R Factory Boost vs. RZR Pro R Factory
Although both machines are designed for competition, Polaris is positioning the new Factory Boost as an additional option rather than a replacement for the existing Gen 2 RZR Pro R Factory.
The Factory Boost introduces a turbocharged 400-horsepower powerplant, longer wheelbase, wider cockpit, revised aerodynamics, and increased fuel capacity.
The existing RZR Pro R Factory remains available for racers who prefer the established platform.
Offering both vehicles allows Polaris to serve different racing requirements while continuing to develop its factory-built UTV racing program.

RZR Factory Racing Targets 2027 King of the Hammers Debut
The new RZR Pro R Factory Boost is scheduled to make its competition debut at the 2027 King of the Hammers, where the RZR Factory Racing team plans to enter the machine in multiple races.
The event will provide an early opportunity to evaluate the new platform against some of the most demanding terrain in off-road motorsports.
With 400 horsepower, a significantly revised chassis, race-specific suspension, and increased fuel capacity, the Factory Boost brings substantial changes to Polaris’ competition lineup.
For professional teams and serious privateer racers, the new machine offers a factory-engineered platform designed to compete at the highest levels of desert racing.
Whether those upgrades translate into continued racing success will become clearer once the Factory Boost begins competing in 2027.
