You have a CVT, belt transmission. The 2015 model uses a newer CVT chain transmission. With each new design designers are able to make the overall system more efficient, less parts, etc... Thus the slight improvement in mileage. Officially it's a 1 mpg improvement.

BTW, some QX60 owners will kill for your more "reliable" belt-transmission.

Good info!

Random but how's does the pathfinder get such good gas mileage?

 

[yeller]

QX60 gets 20/26 while the Pathfinder gets 20/27.

That 1 mpg can be accounted for in the additional QX60 sound deadening, different parts, etc...

The newer CVT has a wider ratio range, so its cruise RPM is lower. It also uses less ATF in the case "bath", so there is less viscous friction.
