I was watching TV and saw the commercial for the Nissan Juke and decided to check it out because of the appearance of a manual electronic boost controller as part of the console. While looking at it, I couldn't help but notice the option of a Continually Variable Transmission as an option. This piqued my curiosity in the technology and as I was researching it I found that Subaru has one, Dodge did have one, don't know if they're still using it and Nissan has 2 that they're using. I haven't found any other car manufacturers that are using them, but other than Subaru, they're front wheel drive setups with AWD options.

What is the common consensus on being able to get a CVT in one of our little cars? I know it wouldn't be a bolt on and drop in fit, but as far as mounting it to the cradle and fabbing an adapter plate I can't see it being that big of an issue. The only real hurdle I can see would be the electronics to control it, right? Or is there something I'm missing?

Thoughts, comments?

That looks awfully familiar... 600 XLT?

Yeah, that's what I'm talking about. It seems to be simple technology and the only things that would really make it a challenge to implement would be the controller, I think.

I'm guessing that won't hold up in a car... The car CVT's that I've seen have a pretty mean looking steel "belt" to hold up to the torque. From what I hear that's the hard part of them...

Mini Cooper also used a CVT, but apparently not a great one. My fiance's Mini has one, I'd much prefer a standard or a good auto. -> http://forums.roadfly.com/f...ooper/9067189-1.html

Seems like a great idea if done right. Can set it up to run the engine at peak horsepower or peak efficiency..

That's what I was thinking, you can have the best of both worlds with this transmission, but it would take some serious ECM programming to implement. Like I said in my original post, the new Nissan Juke has a CVT as an option, and every review I've read has only good things to say about it which got me thinking about trying to fit one in a Fiero.
