During Hay Days 2026, held September 12–13 in North Branch, Minnesota, the SledMagazine.com team had the opportunity to meet with Steve Cowing of Ski-Doo and take a closer look at one of the Canadian manufacturer’s most exciting new developments: the Rotax 600RR E-TEC engine.
With 130 horsepower, a claimed 20% quicker throttle response, and new engine management technologies, this two-stroke twin represents a significant evolution of the popular 600R E-TEC.
Exclusive Interview: Steve Cowing Introduces the New Rotax 600RR E-TEC
Steve Cowing of Ski-Doo introduces the new Rotax 600RR E-TEC engine during Hay Days 2026 in Minnesota. Exclusive interview by SledMagazine.com.
For snowmobile enthusiasts, Hay Days offers a unique opportunity each year to discover the latest manufacturer innovations and speak directly with key figures in the powersports industry.
During our visit to the Ski-Doo booth, Steve Cowing introduced us to the new Rotax 600RR E-TEC, an engine that now plays an important role in the 2027 Ski-Doo lineup.
This new powerplant isn’t simply about producing more horsepower. Ski-Doo has also focused on throttle response, electronic engine management, and fuel efficiency.
Let’s take a closer look at what these improvements mean for snowmobilers.
Rotax 600RR E-TEC: 130 Horsepower and Sharper Acceleration
The new Rotax 600RR E-TEC retains a liquid-cooled, two-stroke twin-cylinder design with a displacement of 599.4 cc.
However, several improvements take its performance to the next level.
Output now reaches 130 horsepower, an increase of five horsepower over the previous 600R E-TEC.
Perhaps the most interesting improvement, however, is throttle response.
According to Ski-Doo, the new engine delivers up to 20% quicker throttle response, thanks in part to new auxiliary injectors and a higher maximum engine speed of 8,250 rpm.
For riders, this should translate into a more immediate response when opening the throttle, particularly when exiting corners or accelerating along the trail.
This evolution could make the riding experience even more engaging while maintaining the versatility that made the 600R E-TEC so popular.
A New Approach to E-TEC Fuel Injection
The Rotax 600RR E-TEC continues to use BRP’s E-TEC direct-injection technology, complemented by auxiliary injectors.
This configuration allows precise fuel delivery management based on engine demands.
The manufacturer’s goal is to deliver improved throttle response, optimized combustion, and reduced fuel consumption under certain operating conditions.
This approach demonstrates that modern two-stroke engine development is no longer focused exclusively on increasing horsepower.
Efficiency, smooth operation, and electronic control are becoming increasingly important.
Smart ECO: Improving Fuel Efficiency Without Sacrificing Performance
Among the technologies introduced with the Rotax 600RR E-TEC, Smart ECO deserves particular attention.
Unlike a traditional economy mode that generally limits performance, this technology automatically adjusts engine management to help reduce fuel consumption.
When the rider demands more power, the system allows the engine to quickly deliver the performance available.
It’s an interesting approach for snowmobilers who enjoy spirited riding but also value fuel efficiency.
Ski-Doo claims reduced fuel consumption under certain conditions without compromising the overall riding experience.
Of course, real-world results will depend on riding style, snow conditions, terrain, and the particular snowmobile model.
Silent-Stop: A Practical Innovation for Trailside Stops
Another interesting innovation is Silent-Stop.
This technology allows the engine to shut off automatically during certain stops and restart when the rider is ready to move again.
The goal is to reduce unnecessary idling, particularly during longer stops.
This could help lower fuel and oil consumption while improving the overall riding experience.
For riders who enjoy long-distance touring, this feature represents an interesting development in two-stroke engine technology.
However, its behavior under different riding conditions will need to be evaluated to determine its true benefits on the trail.

Which 2027 Ski-Doo Snowmobiles Feature the Rotax 600RR E-TEC?
The new Rotax 600RR E-TEC isn’t limited to a single category of snowmobiles.
Ski-Doo offers this engine across several model families in its 2027 lineup, including:
- MXZ: Designed for riders who enjoy sporty trail performance.
- Renegade: Built for those seeking versatility and performance over longer distances.
- Backcountry: Intended for riders who split their time between groomed trails and off-trail adventures.
- Summit: Designed for deep-snow and mountain riding enthusiasts.
- Expedition: Offering versatility for crossover and utility-oriented applications.
Engine availability varies by model, version, and configuration.
This wide range of applications demonstrates the strategic importance Ski-Doo places on its new engine.
Rotax 600RR E-TEC: An Engine That Could Appeal to Many Riders
For years, choosing a more powerful engine often meant accepting higher fuel consumption and certain compromises in everyday use.
With the 600RR E-TEC, Ski-Doo is attempting to achieve a more attractive balance.
Its 130 horsepower should satisfy a broad range of snowmobilers, particularly those looking for a lively, responsive, and enjoyable machine.
The improved throttle response could also be a major selling point for riders who appreciate a more aggressive riding style.
Meanwhile, Smart ECO and Silent-Stop demonstrate the manufacturer’s commitment to improving the overall riding experience beyond pure performance.
This is certainly an engine worth paying attention to.
Meeting Steve Cowing at Hay Days: A Closer Look at Ski-Doo’s Evolution
Our visit to Hay Days gave us the opportunity to meet Steve Cowing and examine this new engine up close.
Beyond the horsepower figures, the Rotax 600RR E-TEC illustrates an interesting direction for Ski-Doo: developing engines that are more responsive while also better meeting the evolving expectations of today’s snowmobilers.
With this new powerplant, the Canadian manufacturer demonstrates that two-stroke engine technology still has considerable room for advancement.
Of course, the real conclusions will come after extended testing on snow, when we can evaluate its performance, fuel consumption, and riding characteristics under actual trail conditions.
One thing is certain: on paper, the new Rotax 600RR E-TEC has everything it takes to capture the attention of snowmobile enthusiasts!
