Då har Polaris släppt 2019 och den stora grejen är den nya motorn. Man har börjat med ett så gott som blank papper på denna motor som man utvecklat under ett antal år. Enligt motorteknikern bakom motorn ska den ha mer effekt än Rotax motsvarighet med en ökning på 9% jämfört med 800:an.
The Polaris Liberty® engine lineup is expanding with the introduction of the all-new Polaris 850 Patriot Engine, a powerful new member of the Liberty family that includes the 600 Cleanfire® and 800 H.O. Cleanfire® Engines.
With the knowledge gained from 25 years of legendary Liberty engine manufacturing, the Polaris Powertrain Team started with a clean sheet and a focus on durability as they developed the all-new Polaris 850 Patriot Engine – the most powerful Polaris snowmobile engine ever.
