The 2019 Polaris snowmobile lineup has been unveiled and the big news is the introduction of the new Polaris 850 Patriot engine, which is found in a number of sleds.

It’s the most wonderful time of the year as snowmobile manufacturers are unveiling their newest creations and the 2019 Polaris snowmobile lineup is looking very interesting – thanks in large part to a big boost in power.

What makes the 2019 Polaris snowmobile lineup so intriguing is a new Polaris 850 Patriot engine, which will power a number of new sleds across the RMK, Switchback, Rush and Indy line-ups.

According to Polaris, the 850 Patriot is a clean-sheet design. In fact, Polaris says the only parts used on other Polaris engines are the spark plugs, two sensors and some common fasteners. Polaris designed the Patriot 850 with reliability in mind and it is backed up by a four-year warranty.

What can we expect from the Patriot 850? Polaris promises this engine offers unrivaled acceleration is the quickest revving in the industry thanks to 13% less rotating intertia than its closest competitor. Horsepower also sees a 9% bump over the Polaris 800 H.O. engine. While Polaris didn’t give us an exact horsepower number, assuming the 800 H.O. produced about 160 horsepower, the new Patriot 850 should be somewhere in the neighborhood of 174 horsepower. Polaris also boasts it has industry-leading power-to-weight ratio with a 9% advantage over any other competitive mill.
