The Ski-Doo Summit 850 E-TEC Turbo is a snowmobile that completely redefines high elevation riding and takes the industry to new heights. Riders will experience factory-built power in a way never before attainable until the Summit 850 E-TEC Turbo.

Riders also get never before seen manufacturer-backed ease of use and peace of mind – because this is the world’s FIRST EVER OEM-built 2-stroke turbo engine.

The high elevation experience gets easier and more fun as deep snow pilots get the same kind of power their low elevation comrades have had for years, with no turbo lag and the same renowned ultra-quick throttle response Rotax 850 E-TEC engines are famous for.

The first ever factory produced 2-stroke turbo also lets riders enjoy centrally balanced handling, lighter weight and consistent performance, as altitude increases. Peace of mind is part of the package too with perfect factory integration, accurate calibration at all altitudes, in all conditions and the reassurance of a factory warranty.

Riders will enjoy every ounce of the 165 horsepower from the industry’s leading 2-stroke engine to its fullest, all the way to 8,000 feet (2438 m) in altitude. They continue to enjoy a 40-hp advantage over non-turbo 850’s from there up on the way to discovering stunning new winter playgrounds.

This 2020 late release Ski-Doo model begins with the REV Gen4 platform. So responsive, a simple glance is all it takes to point it in the rider’s desired direction. There’s no deep-snow snowmobile that translates the relationship between rider, sled and epic terrain better than the Summit.

More than a new engine, it’s a complete lightweight, turbocharged package fully designed by Rotax and Ski-Doo. In addition to delivering all its power at less weight than aftermarket turbo kits, the optimized layout in the chassis keeps the sled balanced side to side for easier handling. Available at dealers now, the Summit 850 E-TEC Turbo also comes standard with a new one-piece lightweight hood.

Technology background for Rotax 850 E-TEC Turbo

Designed specifically for the 850 E-TEC entirely within Rotax walls, the new turbo ensures full use of the 850 E-TEC’s 165 horsepower all the way up to 8000 feet and then maintains a significant 40-horsepower advantage over normally aspirated engines from 8000 feet to the top of any mountain.

When designing the new 850 E-TEC Turbo engine, four key factors were front and center for Rotax and Ski-Doo engineers to ensure optimal consumer satisfaction:

1. Responsive power delivery with no lag,
2. durability,
3. light weight
4. seamless integration into the responsive REV Gen4 platform.

Optimizing power at minimal boost was critical for both throttle response and longevity. An intake with a short-track bypass tract keeps throttle response crisp and quick, while the streamlined exhaust system minimizes backpressure.

An electronically controlled wastegate maintains consistent boost pressure (up to 4 PSI) and delivers it precisely as needed, to ensure the dynamic performance characteristics of the 850 E-TEC are never lost.

The in-house Ski-Doo/Rotax design advantages are immediately felt when riders experience how flawlessly the turbo package performs from idle to wide open throttle and how it integrates with the rest of the snowmobile. The compact turbine and compressor are ideally fitted within the REV Gen4 chassis.

The lightweight material along with a patented lightweight continuous oiling system and optimized down pipe are laid out to ensure the entire powerpack stays centrally balanced within the frame.

It’s all wrapped in a new one-piece lightweight hood and unique side panel with strategically placed venting for optimal cooling of critical power-producing components, and sleek, sexy styling.
