This is still confusing, do I read this right? the VCM is better in the city and the non-VCM gets better mileage on hwy?Third Gen 2010 - City VCM/17 NonVCM/16 - Hwy VCM23 NVCM25
Third Gen 2009 - City VCM/17 NVCM/16 - Hwy VCM23 NVCM25
Third Gen 2008 - City VCM/17 NVCM/16 - Hwy VCM23 NVCM25
Third Gen 2007 - City VCM/17 NVCM/16 - Hwy VCM23 NVCM24

First, VCM is very unlikely to kick in during city driving (if ever) and the whole point of it was/is for hwy running when it can kick in.
My experience is VCM only kicks in during steady running above 30-35 mph and even then it drops out at the slightest upgrade (avoid the cruise control if you want max VCM). Also, my mpg clearly improve with hwy driving when VCM is available.
Maybe the chart numbers are just reversed.
