Vehicle Information
Ski-Doo Summit 850 Snowmobile (2017-2026)
The Ski-Doo Summit 850 (2017-2026) is a mountain snowmobile designed for deep-snow enthusiasts, renowned for its advancements in engine technology and chassis design. Powered by the 849cc Rotax 850 E-TEC two-stroke engine, this model has evolved to deliver exceptional performance. The 2017-2026 period saw significant innovations. In 2017, the REV Gen4 platform and the 850 E-TEC engine were introduced, optimizing handling and rider control. The 2020 model year brought the 850 E-TEC Turbo engine, a first for a mass-produced turbocharged two-stroke, delivering 165 horsepower up to 8,000 feet of elevation. A major shift occurred in 2023 with the launch of the narrower and lighter REV Gen5 platform, accompanied by the powerful 180-horsepower 850 E-TEC Turbo R engine. Continuous refinements, such as in 2026 with the Summit X Expert Package, further enhanced lightness and maneuverability. FAQ:
