The world of supercars and hypercars is dominated by a single solitary materials: carbon fiber. A composite materials, it is used all through these sports activities vehicles’ our bodies, their suspensions, and are even used to construct the chassis on which all the pieces sits. Why? As a result of these supplies are light-weight, sturdy as shit, and could be molded into no matter form or type these firms want.
However carbon fiber, particularly the kind of carbon fiber that is used within the automotive world, is dear to provide. You want giant autoclaves, giant printing machines, and all the bottom supplies to make the carbon fiber itself, too. Hell, it is best to see the dimensions and manufacturing course of for Christensen Arms’ barrel wrapping on my rifle. It is a testomony to simply how intensive and huge a manufacturing line you want even for one thing so simple as quite a lot of carbon fiber sheets.
And so, there’s good cause why the overwhelming majority of automotive producers have not adopted the expertise for regular on a regular basis use. And there is even higher cause for why the powersports world, exterior of some carbon fiber panels right here and there, have not adopted it both. Margins are smaller right here, and also you’d want a wholesome funding within the infrastructure.
That, nonetheless, apparently is not stopping Polaris from trying towards the long run and patenting what seems to be the primary carbon-fiber/composite-framed snowmobile. Have a look.

Whereas scrolling the US Patent Workplace’s newest and best, I got here throughout a patent titled, “Straddle Automobile Chassis with Composite Superstructure” from Polaris Industries. Give Polaris solely has a number of straddle-type autos—ATVs and snowmobiles, RIP Timbersleds—my curiosity was piqued, particularly given the composite nature of all of it. However the patent itself is far more attention-grabbing than the title lays out.
“A composite superstructure of a straddle-type car, resembling a snowmobile, fashioned from a fiber bolstered polymer and lengthening from a ahead part coupled to a ahead portion of a chassis of the car to a rearward part coupled to a rearward portion of the chassis, the place the superstructure defines at the very least one steering publish mount configured to couple with a portion of a steering meeting of the car,” states the patent’s summary.
The outline goes on to relay, “The current disclosure describes straddle-type leisure autos, together with, however not restricted to, snowmobiles, all-terrain autos, private watercraft, and two- or three-wheeled bikes, having a number of composite body assemblies extending from a place ahead of a steering system of the car and both defining or coupled to border members supporting at the very least one among an operator space, straddle seat of the car, gasoline tank, or tunnel. The described composite body members facilitate manufacturing of the car by lowering half depend, meeting steps, meeting time, or combos thereof. Moreover, in comparison with different body members configurations, the described composite body assemblies could scale back the whole weight of the car, scale back weight over the middle of gravity of the car, and stiffen the whole car construction thereby offering for improved efficiency, dealing with, or each.”
Now, a number of issues. First, as you possibly can see within the patent drawings, what we have now is a snowmobile that seems to sport a composite body, i.e. carbon fiber. Snowmobiles are pretty heavy issues, so any quantity of weight discount within the sled’s chassis goes to pay dividends, particularly for backcountry sleds that see additional weight decreases in comparison with path sleds. Second, swapping from an aluminum/steel observe tunnel to 1 made from carbon fiber or another composite could possibly be an superior development in lowering the observe’s warmth when you must hit ice or hard-pack snow, as carbon fiber does not are inclined to warmth up in the identical manner as steel does. In reality, it’s miles higher at warmth dissipation.
Lastly, it is attention-grabbing that Polaris mentions PWCs and bikes, as the corporate does not manufacture both. Are these coming?
As for once we’ll see this expertise on an actual, manufacturing snowmobile, that is anybody’s guess. However the truth that this patent exists tells me that we would see it fairly quickly, and that Polaris is investing in its future, in addition to the way forward for its snowmobiles in far wilder methods than we may’ve ever imagined. I can not wait to see this within the flesh.
