This is all good info - thanks for the CVT anecdotes.


Versa: your car uses the same JATCO CVT-7 transmission as in the Mirage I drove. Though it could be programmed differently for different applications (1.6L 109 HP vs 1.2L 78 hp).


Considering pretty much the only reason for building CVT's is improved fuel economy, it sure is odd that they don't do DFCO as much as other transmission types.

I wonder if it's partly because there aren't enough DFCO opportunities built into the various fuel economy test "routes" (driving patterns).


Rooster: your experience of seeing "boosted" RPM when going downhill is interesting. Do you mean RPM goes up higher than you'd see for example with a fixed gear connection to the wheels (like a manual) as speed increases?
