The world has been waiting. Ski-Doo has delivered again, with the first-ever 2-stroke turbocharged engine in the Rotax 850 E-TEC Turbo. Perfectly melded with the ultra-agile REV Gen4 platform, the Summit 850 E-TEC Turbo delivers maximum power up to 8,000 feet and continues to deliver 40 more HP than naturally aspirated 850-class engines as the ride climbs higher in elevation.
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.
