We asked our test riders to choose their favorite ultra deep powder snowmobile of the year and the 2019 Ski-Doo Summit X 175 earned the honor.

When it came to choosing their award winners for the 2019 model year, perhaps the most contentious category among the Snowmobile.com mountain team was the Ultra Deep Powder Snowmobile of the Year. Ultimately, the 2019 Ski-Doo Summit X 175 edged out the Polaris Pro-RMK 174 by the narrowest of margins.

According to our test riders, it was the Summit’s 16-inch wide track (the Pro-RMK sports a 15-inch track) and nose lift from a quick throttle snap that gave Ski-Doo the top honor for 2019.

2019 Ski-Doo Summit X 175

Not an easy pick. This, along with the Most Improved category, was our most debated. We give this again to the Gen-4 Ski-Doo Summit X 175. Though the Pro-RMK 174 deserves every bit of recognition as the 175 Summit X (and SP), it is the Summit’s 16-inch wide track (versus the Pro-RMK’s 15-inch wide) and nose lift from a quick throttle snap to hop around a tree blow hole, that give the Summit 175 a slight margin lead over the Pro-RMK.

The the Gen-4 850 Summit X 175 acts much like a 165 Summit X, but is more stable on a mountain’s side from nose to tail. This sled is nimble, fast, powerful and is pretty much exactly what you are looking for in an ultra deep powder snowmobile.

An 849cc Rotax engine provides the power for the Summit X 175, dishing out 165 horsepower at 8,000 RPM with more than 106 lb-ft of torque. When it comes time to hit back at a mountain that is trying to defeat the climber and his or her mission, the big 850 with boost injection gives the Ski-Doo Summit X 175 the extra oomph to hit back and win.

Honorable Mention

2019 Polaris 850 Pro-RMK 174

We can’t forget the 2019 Polaris 850 Pro-RMK LE 174. Its new front end, planted stance, grunt-filled 850 Patriot motor, and coil-over Walker Evans shocks make it an ultra deep powder snowmobile champion as well. It matches up with the Summit X 175 about as evenly as two snowmobiles can.
