The 2021 RZR Pro XP4 1000 Ultimate is a high-performance UTV that showcases Polaris’ extensive experience in the off-road industry. Designed for both recreational riders and serious enthusiasts, this model delivers an impressive combination of power, suspension, and technology. The Ultimate package includes premium features such as Dynamix 2.0 active suspension, factory-installed LED lighting, and Polaris’ Ride Command system. While it offers plenty of strengths, certain aspects—especially the Ride Command—leave room for improvement.
One of the standout features of the RZR Pro XP4 1000 Ultimate is its suspension. The Dynamix 2.0 system provides a smooth and responsive ride, automatically adjusting the shocks in real-time based on terrain and driving conditions. This technology enhances stability, control, and comfort, making the vehicle perform exceptionally well on both high-speed trails and technical rock crawling. The long-travel suspension soaks up bumps with ease, keeping passengers comfortable even in rough terrain.
Power is another strong point of the Pro XP4 1000 Ultimate. The turbocharged 999cc engine delivers robust acceleration and maintains plenty of torque throughout various riding conditions. Whether climbing steep inclines, tearing through open deserts, or navigating tight trails, the RZR provides the necessary power to handle it all. The throttle response is crisp, and the overall performance makes it an exciting machine to drive.
However, a major downside of this model is the Ride Command system. While the idea of an integrated touchscreen system with GPS, Bluetooth, and group communication features is appealing, its execution has been problematic. Many owners, including myself, have experienced persistent issues that require multiple trips to the dealer. Even after a complete unit replacement, the system still fails to function according to factory specifications. Given the importance of a reliable navigation and communication system on long rides, this is a frustrating shortcoming in an otherwise well-built vehicle.
Despite the Ride Command issues, Polaris’ experience in the UTV industry is evident in the overall design and build quality of the Pro XP4 1000 Ultimate. The vehicle feels well-engineered, with thoughtful ergonomics, comfortable seating, and user-friendly controls. The chassis is rigid and durable, providing confidence when pushing the machine to its limits. Polaris has been refining its RZR lineup for years, and that expertise shines through in many aspects of this model.
Overall, the 2021 RZR Pro XP4 1000 Ultimate is a powerful and capable UTV with top-tier suspension and performance. It excels in handling rough terrain with ease, making it a great choice for adventure seekers. However, the Ride Command system remains a major drawback, as ongoing issues make it unreliable. If Polaris could resolve these technical problems, the Pro XP4 1000 Ultimate would be even closer to the perfect all-around UTV.
