Polaris Just Announced the RZR Pro R Boost — Their Most Powerful RZR Ever

By Trail Tested TX | Houston, TX

Polaris dropped their full 2027 off-road lineup today, and the headline news is a big one for anyone in the SxS world: the RZR Pro R Boost, a turbocharged version of their flagship Pro R platform. Polaris has offered turbocharged RZRs before — the RZR Turbo S and Pro XP among them — but this is the first time that turbo power has landed on the Pro R chassis, and the horsepower number is the highest Polaris has ever put in a RZR. As a RZR Pro XP4 owner myself, this is the kind of announcement that gets my attention.

The Headline Number: 275 Horsepower

The RZR Pro R Boost is built around a ProStar Fury 2.0L turbo engine putting down 275 horsepower — Polaris is calling it the most powerful RZR they’ve ever produced, and it’s hard to argue. For comparison, the current naturally aspirated RZR Pro R tops out at 225 horsepower, so this is a real jump, not an incremental bump.

A few things stood out to me reading through what Polaris is doing to actually put that power to the ground, since a bigger number on paper doesn’t mean much without the supporting hardware:

• New high-capacity clutch system with added cooling fins and a larger clutch design, aimed at reducing heat and extending belt life — something turbocharged UTV owners already know is a real concern under sustained load
• All-new dual-radiator cooling architecture to manage engine, turbo, and transmission heat together
• Reinforced driveline components, including strengthened half shafts, built specifically to handle 275 horsepower in extreme terrain
• Turbo tuning that holds peak power up to 10,000 feet of elevation — a detail that matters a lot if you’re running anywhere in the mountains, not just desert running at sea level

Two Trims, Two Passenger Configs

The Pro R Boost comes in both 2-seat and 4-seat configurations, each available in Ultimate and Ultra trims.

• Ultimate gets desert-tuned DYNAMIX suspension with new G-out protection and rear bump control.
• Ultra steps up to DYNAMIX DVS with an active sway bar system that adjusts up to 200 times per second, plus a carbon fiber hood and seat bezels, an upgraded steering wheel, 32″ BFGoodrich tires, and exclusive paint.

It also picks up Apple CarPlay compatibility, which is a first for the Pro R lineup as far as I’m aware.

Price and Availability

Starting MSRP is $49,999, with dealer shipments beginning November 2026. That’s a serious price tag, but it’s also a serious machine — this isn’t a trim bump, it’s a new powertrain architecture built from the ground up to handle turbo power reliably. Full specs and configurator are up on Polaris’s official RZR Pro R page if you want to dig deeper.

What Else Came Out Today

Polaris didn’t stop at the RZR. A couple other pieces of the 2027 announcement worth knowing about if you’re cross-shopping or just keeping tabs on the brand:

• Polaris XPEDITION now offers NUMATIX, the industry’s first pneumatic CVT — a drive clutch controlled by air pressure instead of the usual mechanical setup, which Polaris says cuts perceived noise by up to 40% at 35 mph while still delivering full CVT responsiveness. It also adds reinvented drive modes (Comfort, Standard, Sport) and an integrated on-board air system for trailside tire inflation.
• Sportsman 500 joins the ATV lineup as a genuinely budget-friendly option — $6,999 MSRP, 2,500-lb winch, 11.5″ ground clearance, and an auto-locking front drive system that engages automatically when it senses wheel slip.

My Take

I run a RZR Pro XP4, not a Pro R, so this doesn’t directly affect my rig — but it’s a meaningful signal about where Polaris is headed. Bringing turbo power to the Pro R platform for the first time is a big architectural bet, and the amount of supporting engineering around cooling and driveline strength tells me they’re not just chasing a bigger horsepower number for a spec sheet — they’re building it to actually survive real desert running at that power level.

If you’re in the market for a new machine this fall, or just curious how this stacks up against the naturally aspirated Pro R, I’ll be keeping an eye on early reviews once these start hitting dealers in November.
