Although hydrogen and electric engines have been at the forefront of innovations featured in headlines, Arctic Cat has gone down an alternate route. The well-known snowmobile manufacturer has revealed the first-ever ‘magic number’ snow engine that shows unseen performance.<\/p>\n

The 858 engine is quite the revolutionary powerplant<\/strong> that was built for Arctic Cat’s CATALYST\u2122 platform. Instead of pursuing other fuel sources, Arctic Cat focused on raw mechanical innovation, creating an engine that redefines performance for snow vehicles. The showstopper of this creation, however, is a “magic number” -858. 858 is not just a name, it is a specific engineering choice that maintains the balance between power, agility, and efficiency like never before.<\/p>\n

858: Anything but an ordinary number<\/h2>\n

Why is there a strong focus on 858?<\/em> Arctic Cat\u2019s decision to rely on 858 was thoroughly considered. The name comes directly from the engine\u2019s displacement: 858cc, derived from a bore of 85mm and a stroke of 75.6mm. As opposed to manufacturers who chase bigger numbers for marketing appeal, Arctic Cat engineers are after balance.<\/p>\n

The magic lies in keeping the bore the same as the predecessor’s 800 C-TEC2 engine. The stroke is extended by 8%, which makes it possible for the Arctic Cat to increase the power whilst still keeping the engine compact and light. A wider bore could have resulted in an engine that’s bulkier and more prone to higher piston temperatures, whilst still compromising durability. The magic number 858<\/strong> allows the engine’s design to keep a slimmer profile, allowing for lower emissions without affecting performance. The result is a snow engine design without any bulk but with a great power-to-weight advantage.<\/p>\n

858 is the magic number that enables weight, reliability, and performance to intersect seamlessly for the CATALYST chassis.<\/p>\n

The engine with a catalyst chassis makes it great for performance<\/h2>\n

The way the 858 was developed makes it unique.\u00a0 Arctic Cat, however, created the engine and the catalyst chassis in tandem which surely is unique in the industry. The amalgamation has allowed engineers to harmonize engine position, intake angles, and weight distribution. The combination ensures greater performance with a lower center of gravity, improved agility, and greater mass centralization<\/strong>.<\/p>\n

The engine has other carefully thought-out features:<\/p>\n
