The first-ever factory-built 2-stroke turbocharged engine in any industry. 2020 Ski-Doo Summit® Sport 850 E-TEC® Turbo WE CHANGED THE RULES The first factory-built 2-stroke turbocharged sled is here. The Rotax 850 E-TEC Turbo is purpose built for the REV Gen4 platform with never-before-seen 2-stroke power delivery and precision handling to create the ultimate sled for technical riding. Features may include: ROTAX 850 E-TEC TURBO ENGINE ELEVATION DOESN'T STAND A CHANCE The first-ever factory-built 2-stroke turbocharged engine in any industry. The Rotax-designed and built turbo provides full 165 HP* from the industry’s strongest 850 twin up to 8,000 feet of elevation and maintains a 40-HP advantage compared to normally aspirated 850’s. Sophisticated design integrates flawlessly with the REV Gen4 platform for ideal balance at minimal weight. Ultra-impressive power, instant response with no lag, and factory reliability from a turbocharged 2-stroke - only the industry’s leading manufacturer could develop and stand behind it. SHORT TUNNEL DROP THE DRAG Go more places with a shorter tunnel length allowing optimal maneuverability in deep snow thanks to exceptional snow evacuation. Standard rear lightweight snowflap with LinQ-ready attachment points to attach optional removable long snowflap. ONE-PIECE LIGHTWEIGHT HOOD LIGHT AND AIRY One-piece Polypropylene construction instantly drops 6 lbs. of weight. Optimized ventilation for heat dispersion and noise reduction. ERGONOMIC DEEP-SNOW DESIGN Purpose-built for a better deep-snow experience with lower seat height, shorter riser, smaller diameter handlebars and low handlebar strap for the ultimate advantage in deep snow. DYNAMIC HANDLING A MORE CONFIDENT RIDE Revised ski spindle and ski stopper for more predictable handling and a confidence-inspiring ride on steep sidehills and rough terrain. E-TEC SHOT STARTER EASIEST STARTING Push-button starting with almost no added weight. After an initial pull-start, the engine charges an ultracapacitor. Pushing the handlebar SHOT button for subsequent starts uses energy stored in the ultracapacitor to turn the magneto into an electric motor that rotates the flywheel, and with E-TEC technology, starts the engine. Eliminates nearly 20 lb. (9 kg) compared to conventional electric start. SHOT starting is only possible with Ski-Doo-exclusive E-TEC technology. TMOTION LIMITER STRAP ADJUSTER DIAL YOUR RIDE Quickly and easily change limiter strap length for desired ski lift without crawling under the sled. KASHIMA COATED SHOCKS SMOOTH RIDE Kashima coating delivers silky smooth shock piston movement for consistent cushioning through every bump - big and small. Plus, adds durability for worry-free performance on every ride. FULL-LENGTH PROFILE RUNNING BOARDS SURE FOOTING Rigid full-length extruded aluminum grid-style design with wide openings for exceptional snow evacuation and superior grip. Flat foot positioning for comfort and control, plus a 1 lb. weight reduction.
