a single coil over shock right through the middle. The snowflap— already petite— is even smaller. The new PowderMax Ultra-Light with Flex Edge track’ s outermost lugs have a bit less width, which not only reduces weight but also its rotating mass. It also sports a powder-friendly Pilot DS 3 ski, unchanged from last season.
The naturally aspirated engine claims 165 hp.

Even with some similarities, the Ski-Doo Summit X 850 E-Tec Turbo R 154 Expert Package is a different beast compared to the X. The Turbo Expert Package uses the aggressive Pilot DS 4 ski, drastically updated for 2026 with an altered keel, changed reinforcements and a bit of weight savings. They’ re built for riders who need a lot of positive carve and line— just a little turn to the bars and the skis grab. This ski is exclusive to the Expert Package.
Also new up front: The S32 twin link steering is a ground-up redesign from the steering post to the sway bar. It’ s lighter in weight and created to have zero bump steer. The RAS 3 front suspension has 8.1 inches of travel from easy-adjust KYB 36 Pro 36 EA-3 shocks. A new, taller spindle accommodates new control arms— with a lower shock bolt mounted through the body of the A-arm to retain travel despite the narrower stance. The steering swing increases by 30 percent with the new setup. Donuts, anyone?
The rear skid retains the rigid arm tMotion XT setup and adjustable limiter strap where a 16- by 154- by 3-inch full-width rod track is installed and KYB Pro36 EA-3 shocks cushion the ride. The shorter tunnel( 45mm on 154 models) saves 5 pounds plus the reduction in carried coolant. Various weight savings shave 6 pounds from Turbo Expert Package to 457 pounds dry. The outside ski width of the narrowed-stance Expert becomes 38.25 inches.
The turbo engine spits 180 hp up to 8,000 feet.
The Summit X 850 E-Tec Turbo R 154 Expert pricing starts at $ 21,649.
HANDLING ⊲
This is the sled to navigate through junk snow on an edge and in control. The improved handling, ability to hold a line without feedback and overall precision surpasses the others in the class.
TRACK ⊲
If you have to give it a grade, it’ s 60-to- 70 percent better at holding an edge than an X, which now feels twitchy.
FRONT SUSPENSION ⊲
The clicker shocks on 1 and 2 are ideal. Leave it on 1 for some easy riding, bump it to 2 if you want to blast a few corners. Overall, solid shocks.
SKI ⊲
I expected the narrow ski stance to make it to flop around, leave me upside down in the rhubarb after turning and be a handful … and it did none of those things.
