How Polaris Fit a 2.0L Engine in an RZR

It was a tight fit.

The Polaris RZR YouTube channel has been carefully releasing RZR Pro R content ever since its official launch on November 9. Today’s batch of videos includes several maintenance tutorials that go over how to change the air filter and spark plugs in the new machine. Coincidentally, it also gives us one of the first looks into how Polaris crammed a 2.0L four cylinder motor into the back of an RZR frame.

We took a first look at this revolutionary RZR during launch day and have since broken it down in our buyer’s guide page to give prospective shoppers a better understanding of what’s new for the 2022 Polaris RZR Pro R. It’s not just a new 225 hp engine. There’s a lot more going on to make this both the most powerful and most expensive RZR ever produced.

From the video we can clearly see that the ProStar Fury 2.0L engine is mounted longitudinally, like a conventional rear-wheel-drive car, down the rear of the RZR’s frame. The long hunk of metal sits tucked under the cargo box with the air cleaner accessible from inside the cockpit’s rear plastic wall. This orientation opposes the horizontally mounted parallel twins that normally fill this space in an RZR frame, with each cylinder sticking off to one side or the other.
