Difference between years

[rightaway1]

I'm looking at buy a full size 2007 and up Chevy SUV, Suburban Ltz, Cadillac escalade esv or Yukon Denali xl. I know that the suburban change the trans to a 6 speed and Chevy cylinder deactivation in 2009. did the other SUV make and major changes in the later years to improve? Wiki and Google is not helping.what year did they add the cylinder deactivation to the 6.2.When I was looking on wiki, the escalade MY10 had it. I have no idea what year is. I couldn't find any info about the Denali.I wish there was a good website that showed you the difference/upgrades to each year

Edmunds doesn't really tell you the difference between each year like what I'm looking for

if you looking for multi-brand vehicle comparisons try some of the magazine sites to see if they have on line reviews from the past car&driver, motor trend, etc. Looking at owners manuals for the Suburban from 2007 to 2013 the only mention of active fuel management is on the 5.3 .

that is Cadillac, GM may introduce something in one brand but that doesn't mean it will be in all brands. Here is a link to Cadillac owners manuals if you want to research when AFM was introduced.
