when will snowmobile manufactures catch up with automotive CVT technology

[paulharris]

considering the doo(and others) belt issues I was watching this video and thinking how archaic the snowmobile cvt/rubber belt system is. they have been using the a rubber belt on snowmobiles for 50+ years with very few changes!! sleds back then had 20hp and today they have 160+. this system is stuck in the dark ages, you go out and buy a brand new sled in 2017 and rubber belt issues are STILL a constant headache and a high cost. the automotive world is light years ahead. i don't see why the snowmobile manufacturers could not adopt a similar technology with non-rubber belts. of course manufacturing costs and weight would probably be the biggest challenges, but think about a permanent belt, no dust, no rubber, no maintenance, no heat, no blown $200 belts. and able to handle the power of todays machines and way beyond with ease. check it out....

I think the biggest reason is weight, the clutches run in an oil bath. The next biggest reason is complexity. The automotive cvt's shift through hydraulic pressure. They don't use springs or weights to determine the shift patterns.

No belts to blow up that would be my dream come true!
