Versa CVT
My neighbor has one and it prompted me to look up the CVT on Youtube. Now I know our Fits aren't the fastest vehicles out there but the CVT trannmission brought only one thing to mind. BORING!
What's the purpose of the CVT tranny?

Infinitely variable gear ratios mean you can always be at the optimal engine rpm for power/acceleration/fuel economy.
Transmissions with set gear ratios are a compromise because you will almost never be at the perfect rpm and ratio for what you are trying to do.

There are CVTs that can lock the drive and driven pulleys into fixed virtual ratios to give the driver a set of virtual gears.
That's what the GDs sold here have: a 7-speed manual mode for the CVT.
Nissan has been developing CVTs for at least 20 years now and from what I remember, the strongest example they make is for the Murano SUV.

I have driven a Jeep and a Murano with CVT. They were both rentals and I put about 400 miles on each during a week. They do give smooth acceleration, but I gotta admit they are boring.
You don't get that low to high rpm to shift, low to high rpm to shift sound that a manual or even an automatic does. When you don't hear that "normal" engine sound the perception is that it has no power. When you read review of CVT the lack of power is the largest complaint. In reality it is just as powerful as a AT or MT, it just doesn't sound like it.

Picture this: You pile on the throttle, but the pickup isn't instantaneous as it would be with a traditional A/T on kickdown.
Instead, with a CVT the engine sticks to a certain engine speed where the torque is greatest...and STAYS THERE. The CVT will then vary its components (toroid, belt, pulley, etc) to deliver the increased road speed. Depending on the engine, said engine speed with peak torque can be pretty loud.
CVTs feed the power smoothly so the acceleration isn't as evident, but it's there. :D
