Q45 CVT

[Haitian_King]

Hey guys,

After reading about CVT's on Wikipedia, I became curious about the possibilities of putting it in a Q. Is it possible? Really outrageously expensive? Is it worth it?

I checked the search for CVT's and the only thing that came up was Louiegz saying that the CVT in his wife's rental MINI Cooper was terrible.

Some benefits I gleaned from the article were increased fuel efficiency and cheaper cost to maintain and repair.

So, any thoughts?

You certainly are full of ideas, eh?

No way is it going to be cheaper to install one. The main downfall about CVTs is that they are just now able to handle reasonable amounts of power. CVTs are weak by nature which is why they are generally used on lighter vehicles with not much HP. You would probably have to custom engineer a CVT from scratch to put into a Q.

In theory they're great... my one experience driving something with one was aweful... of course it was a Jeep Liberty rental beast. Major slush box.... it felt like the motor was hooked to a blender, and the swirling fluid was trying to turn something to propel the car. I didn't realize that it was even a CVT until later...

When is that a bad thing Wes? Otherwise life would be stagnant and boring.

I was just wondering. They made such a big deal in the commercials about the new Maxima and Altima having the CVT.

I've never had any experience with a CVT so I was curious. Oh well.

Far as I know, only the very latest CVTs are any good at all, particularly the ones in Nissans. They simulate gear changes or something?

[Haitian_King]

No idea. I saw the commercial for the Maxima and the guy driving had to imitate gear shifts with his mouth. It gave me the impression that it feels like one continuous acceleration with no shift jerks. Kind of weird though.

When me and Evan had the altima 2.5 with CVT, it was interesting. For regular driving it wasnt too bad for just sloshing around town.. Basically, if you left it in drive and were just poopin around town you wont mind.

This one had the 6 speed "sport shift". That really made the car fun because it simulates 6 gears. it "shifts" faster than Evan's GTI did and was quite a bit smoother...

Im not aware of any CVT setups that are used on longitudinal mount RWD cars.

Basically the way CVTs work is they have 2 different sized pulleys connected together with a belt... As one gets larger the other one gets smaller. The pulleys look similar to 2 cones put tip to tip so the pointy ends are touching. hydraulic pressure (or spring pressure in things like ATVs and snowmobiles) causes the pulleys to either get wider or narrower, thus decreasing the diameter that the belt contacts.

Ah. Interesting.

i could have sworn that the murano i drove was RWD, and had a CVT, i hated it

never lliked the idea of a transmission being (basically) a big rubber band that tightens the faster you wanna go haha

Murano is FWD. Think of it as a tall Altima.
