Ski-Doo Summit 850 E-TEC Turbo Revealed

BRP announces a factory-built 2-stroke turbo 850 engine for its Ski-Doo Summit.

Ahead of the usual spring reveal of new model year sleds, BRP has announced the world’s first factory 2-stroke turbo snowmobile. It’s called the Ski-Doo Summit 850 E-TEC Turbo, and it is essentially a turbo-charged Summit with Expert Package.

In a surprising move, BRP is calling the Summit 850 E-TEC Turbo a model year 2020 sled, and says it is available immediately in limited quantities. Woah!

The technical details of the factory modified 850 E-TEC are not available at this time, but BRP claims the engine will produce 165 horsepower all the way up to 8000 ft elevation and maintain +40 horsepower above 8000 ft.

Fuel and Tuning

BRP says the Ski-Doo 850 E-TEC Turbo will run on pump gas—premium unleaded, 91 octane fuel. The turbo system and ECU will not require any tuning.

The Ski-Doo Summit 850 Turbo will feature a one-piece lightweight hood, that will provide 6 lb of weight-savings to offset the extra addition of the turbo components. BRP says that the Summit 850 E-TEC Turbo adds just half the weight of an aftermarket turbo kit for the same engine.


SHOT Starter

The 850 Turbo will be fully compatible with Ski-Doo’s innovative SHOT starter supercapitor engine starting technology.



The Summit 850 Turbo model will feature HPG Plus Premium shocks that use a lightweight spring technology and are Kashima-coated for superior performance.


Tunnel Length

BRP says that the 2020 Summit 850 E-TEC Turbo sled will come with a short tunnel. Although unconfirmed at this time, it seems likely to be the same short tunnel design as the 2020 Ski-Doo Summit with Expert Package. Other similarities to the Expert Package are listed, such as lower seat height, shorter riders and mountain strap and smaller diameter handlebars.
