Regarding CVT's, the new 2014 Corrola has a new "wide ratio" CVT. It's good to note for the uninformed such as myself, that there is a spread between top and bottom gear in a cvt. So it doesn't have an "infinite" ratio in the sense it can have an infinitely tall top gear.
Taller geared CVT's are great for people who don't know how to hypermile. Last time i looked, a belt and cone CVT was 5-8% less efficient than a manual. A 1:1 stick shift ratio is about 3% more efficient than any other gear.

The CVT by its lonesome was said to provide up to a 2.4 mpgUS boost over and above the previous generations 4-speed AT. A 6.26:1 from bottom to top wide ratio spread will do that for you and per the calculations, the Corolla LE with the CVT runs at just 1,520 RPM at 60 mph which matched the real world revs. IT was back on 09 when we drive the older 160 hp 2.4L Camry motor in a Corolla S with a stick and it was revving in the 2,700 RPM range at 60 mph. This is a huge difference! The ancient 4-speed AT in the base L runs at a disingenuous 2,330 RPM at the same 60 mph.
